`
`ELECTRONIC CAMERA. HAVING IMPROVED
`FOCUS PERFORMANCE
`
`FIELD OF THE INVENTION
`0001. The present invention relates to an electronic cam
`era in which focus performance is improved by emphasizing
`perspective of an image displayed on an LCD.
`
`BACKGROUND OF THE INVENTION
`0002. In recent years, electronic cameras are popularly
`used. In this kind of the electronic camera, image data
`captured by means of a CCD image sensor and so forth is
`converted into digital data and is stored in a memory.
`Meanwhile, storage capacity of the memory increases in
`accordance with high integration thereof and moving-image
`compression technique is improved so that it becomes
`possible to take a moving image. Consequently, Some of the
`commercial electronic cameras are capable of performing
`both of still-image shooting and moving-image shooting.
`0003. When shooting is performed with the electronic
`camera, it is possible to utilize an LCD panel as an electronic
`viewfinder besides a built-in optical viewfinder. On the LCD
`panel, a Subject image formed on the CCD image sensor is
`continuously displayed. Many electronic cameras are pro
`vided with an autofocus function of an active system using
`infrared rays, for the purpose of performing focus adjust
`ment at a time of shooting. Among the electronic cameras,
`there is a single-lens reflex type provided with a manual
`focus function capable of manually adjusting the focus.
`0004. When the manual focus function is used in taking
`an image, a shooter visually finds a focal point by utilizing
`the LCD panel and the optical viewfinder. However, since a
`pixel number of the LCD panel is extremely small in
`comparison with that of the image sensor, the image dis
`played thereon is grainy and it is difficult to finely perform
`the focus adjustment. Moreover, when the LCD panel is
`used, quality of the viewfinder image displayed thereon
`further deteriorates due to dropping frames of the subject
`image continuously displayed.
`0005. In this regard, Japanese Patent Laid-Open Publi
`cation No. 2002-209135 proposes a method in which focus
`aid is performed by using a width of an edge detected from
`an image at a time when the focus is manually adjusted in
`the electronic camera. A user judges a degree of focus on the
`basis of a bar graph showing an evacuation result of the edge
`displayed on the LCD panel.
`0006) Japanese Patent Laid-Open Publication No. 2004
`040740 proposes a method in which a stop is vertically
`moved relative to an optical axis and a focus condition is
`displayed on the basis of image fluctuation to perform the
`focus adjustment. An aperture stop is provided so as to be
`movable at an optical path of a subject from side to side. A
`split image is produced from images obtained when the
`aperture stop is shifted to the right side and to the left side.
`The produced split image is displayed on a monitor.
`0007 Japanese Patent Laid-Open Publication No. 2005
`025055 proposes a method in which a user manually and
`correctly performs focus adjustment of a taking lens even
`when the attached taking lens is not supported by the
`autofocus function. A focal position of a manual focus lens
`is detected by using an AF sensor. At the identical lens
`
`position, the focal position is detected in another way on the
`basis of contrast change of a subject image formed on an
`image sensor. Based on the result of the detected focal
`positions, a built-in main CPU calculates correction data for
`correcting a focus shift amount in displaying focus aid. On
`the basis of the calculated correction data, the focus aid is
`displayed.
`0008. In Japanese Patent Laid-Open Publication No.
`2002-333569, low-pass filter processing of an image is
`abbreviated to facilitate focus adjustment performed by
`using a monitor image.
`0009. However, some of the above-mentioned methods
`are complicated and it is generally difficult to adjust the
`focus because a change of the focus is confusing in the
`manual focus using an electronic camera comprising a
`monitor of an LCD viewfinder type or the like. Further, there
`is an unsolved fatal problem in that it is turned out after
`shooting that the focus was not adjusted even though the
`focus seemed to be adjusted on the monitor.
`
`SUMMARY OF THE INVENTION
`0010. In view of the foregoing, it is a primary object of
`the present invention to provide an electronic camera in
`which a taken image is divided into areas in accordance with
`degrees of focusing and the image is displayed so as to
`emphasize a blur with respect to a non-focus area and so as
`to emphasize sharpness with respect to a focus area.
`0011. In order to achieve the above and other objects, the
`electronic camera according to the present invention com
`prises a focus-degree judging part, an image dividing part, a
`processor and a monitor. The focus-degree judging part
`partitions the image into plural blocks to judge a degree of
`focusing relative to each of the blocks. The image dividing
`part groups the blocks on the basis of the judged degree of
`focusing to divide the image into plural areas every gather
`ing of the grouped blocks. The processor performs different
`image processing with respect to each of the areas. The
`monitor displays the image processed by the processor.
`0012. In a preferred embodiment, the electronic camera
`further comprises a mode changer for Switching a first mode
`and a second mode. Under the first mode, the identical image
`processing is performed for the entire image. Under the
`second mode, different image processing is performed for
`each of the divided areas.
`0013. It is preferable that the electronic camera further
`comprises a focus changer for changing an autofocus and a
`manual focus. In this case, the second mode is automatically
`set when the manual focus is selected by the focus changer.
`0014. In another embodiment, the electronic camera
`includes a detachable lens unit containing an image sensor,
`and an emphasis degree of image processing is changed in
`accordance with a kind of a lens contained the selectively
`attached lens unit.
`0015. It is preferable that the emphasis degree of image
`processing is adjustable in accordance with properties of the
`monitor.
`0016. According to the present invention, perspective is
`emphasized and is expressed on the monitor like a single
`lens reflex. Since a user can easily recognize a focus change
`on the monitor, a focal position is correctly and easily

`
`adjusted. In virtue of this, the user can enjoy taking a
`beautiful picture with the electronic camera.
`0017. In the case that the electronic camera includes the
`detachable lens unit, the emphasis degree of image process
`ing is changed in accordance with the kind of lens of the
`selectively attached lens unit. In virtue of this, the user can
`enjoy taking a beautiful picture without regard to the kind of
`the lens contained in the lens unit.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`0025. An embodiment of the present invention is
`described below with reference to drawings. FIG. 1 is a
`block diagram showing an electrical structure of an elec
`tronic camera according to the present invention. In FIG. 1,
`a CCD image sensor 3 is disposed behind a taking lens 1 and
`a mechanical shutter 2. The taking lens 1 for focusing
`subject light on the CCD image sensor 3 is adapted to be
`moved to a focal position by a lens drive circuit 7, which is
`activated in response to a control signal outputted from a
`central control circuit 8. Meanwhile, a shutter speed and
`shutter timing of the mechanical shutter 2 are set in response
`to a control signal which is outputted from the central
`control circuit 8 in association with timing of a release
`operation of a user.
`0026. The CCD image sensor 3 converts an optical image
`of a subject, which is formed on pixels of the CCD image
`sensor 3, into an electronic signal. In other words, the CCD
`image sensor 3 performs photoelectric conversion. A drive
`circuit 4 produces a transfer pulse and Supplies this pulse to
`the CCD image sensor 3. On the basis of the transfer pulse
`produced by the drive circuit 4, the CCD image sensor 3
`outputs an image signal.
`0027) A CDS (Correlation Double Sampling) circuit 5 for
`reducing noise is activated in response to a drive pulse
`outputted from the drive circuit 4. The CDS circuit 5 is
`connected to the CCD image sensor 3 and an output terminal
`of the CDS circuit 5 is connected to an A/D conversion
`circuit 6, which converts an analog signal into a digital
`signal and outputs the converted digital signal. Image data of
`each pixel of the CCD image sensor 3 is obtained via the
`A/D conversion circuit 6. For the obtained image data,
`
`processing of correction and so forth are performed in a
`signal processor 16. The processed image data is transmitted
`to a focus-area judging part 17.
`0028. The focus-area judging part 17 uniformly partitions
`the image into Small blocks and judges an AF evaluation
`value of each of the blocks. Based on the AF evaluation
`values of the blocks, the focus-area judging part 17 divides
`the image into a focus area and a non-focus area. In this
`regard, the AF evaluation value changes in accordance with
`a position of a focus lens. The AF evaluation value means
`image definition calculated from an integrated high-fre
`quency component of a brightness value of a prescribed
`region included in the Subject image. FIG. 2 shows an
`example in that the image is divided into two areas, and FIG.
`3 shows the AF evaluation values of these two areas. In FIG.
`2, a person located at a central position is in focus, and the
`background including a mountain is out of focus. At this
`time, as shown in FIG. 3, the AF evaluation value is a peak
`of 6 with respect to a scope of the blocks wherein the person
`is taken in a condition that the current position of the focus
`lens is P1. In contrast, the AF evaluation value is 1 with
`respect to a scope of the background blocks. This is because
`a position P2 of the focus lens, which is different from the
`current position, is the focal position of the background
`blocks and the scope of these blocks is out of focus. On the
`basis of the judgment of the AF evaluation values, as shown
`in FIG. 2, the scope of the blocks taking the person is defined
`as the focus area 20 and the whole background including the
`mountain is differentiated as the non-focus area 21.
`0029. The two areas divided by the focus-area judging
`part 17 are respectively processed in different manners and
`are displayed on an LCD 12 in a state that perspective is
`emphasized. For example, the focus area 20 is processed by
`an edge emphasizing processor 14 So as to emphasize
`sharpness. On the other hand, the non-focus area 21 is
`processed by a low-pass filter processor 15 So as to exag
`gerate a blur. The focus area 20 and the non-focus area 21
`are composed again as the Sole image data in a Subsequent
`monitor-image composing processor 13. The composed
`image is displayed on the LCD 12 via an LCD drive circuit
`11. By the way, in case the AF evaluation values are identical
`relative to the entire image and it is impossible to divide the
`image into plural areas, the entire image is uniformly
`processed and is outputted to the LCD.
`0030. As to the process to be performed for each of the
`areas, the electronic camera 18 may be provided with a
`mode selection switch9 as shown in FIG. 4 to select whether
`the process is performed or not. The mode selection switch
`9 changes a display mode between a perspective emphasiz
`ing mode in which the process is performed, and a normal
`mode in which the process is not performed. The display
`mode may be changed by a user. In the case of changing the
`display mode, the central control circuit 8 executes a pro
`cedure along a flowchart shown in FIG. 5. At a shooting
`time, the electronic camera automatically moves the lens to
`the focal position after completing a search process of AF
`(Auto Focus). When the mode selection switch9 is slid to a
`side of the normal mode, namely when the normal mode is
`set, the entire image is uniformly processed and is displayed
`on the LCD. And then, the procedure is terminated. In the
`meantime, when the mode selection switch9 is slid to a side
`of the perspective emphasizing mode, namely when the
`perspective emphasizing mode is set, the taken image is

`
`partitioned into plural blocks and the evaluation values of
`the respective blocks are obtained. Based on the obtained
`evaluation values, the image is divided into areas. If the
`evaluation values are identical relative to the entire image,
`the image is not divided and is uniformly processed simi
`larly to the normal mode. The uniformly processed image is
`displayed on the LCD. And then, the procedure is termi
`nated. When the image is divided into plural areas, the image
`of each area is differently processed in accordance with a
`level of the evaluation value. After that, the image is
`displayed on the LCD and the procedure is terminated.
`0031. In a case that the electronic camera is provided
`with an AF/MF selection switch 10 for changing AF (Auto
`Focus) and MF (Manual Focus), the image of each area may
`be automatically processed only when the MF is selected. In
`virtue of this, convenience for a user is improved. In this
`case, the central control circuit 8 executes a procedure along
`a flowchart shown in FIG. 6. When the AF/MF selection
`switch 10 is set to the AF mode at a shooting time, the
`electronic camera automatically moves the lens to the focal
`position after completing the search process of AF. Then, the
`entire image is uniformly processed and is displayed on the
`LCD. After that, the procedure is terminated. Meanwhile,
`when the AF/MF selection switch 10 is set to the MF mode,
`a user manually adjusts the lens to the focal position. The
`image is partitioned into plural blocks and the evaluation
`values of the respective blocks are obtained. On the basis of
`the obtained evaluation values, the image is divided into
`areas. If the evaluation values are identical relative to the
`entire image, the image is not divided and is uniformly
`processed similarly to the AF mode. The uniformly pro
`cessed image is displayed on the LCD and the procedure is
`terminated. When the image is divided into plural areas, the
`image of each area is differently processed in accordance
`with a level of the evaluation value. After that, the processed
`image is displayed on the LCD and the procedure is termi
`nated.
`
`0032. A camera system 30 shown in FIG. 7 comprises a
`lens unit 32, which contains an image sensor and is detach
`able from a camera body 31. In the camera system 30, it is
`effective to change the emphasis degree of image processing
`and the level division number of the AF evaluation value in
`accordance with the kind of the lens unit 32, such as shown
`in the above Table 1.
`0033. The perspective is easily expressed by a bright lens
`in accordance with an f-number thereof, because a depth of
`field is shallow. On the other hand, however, it is difficult to
`distinguish the perspective with a dark lens. In this case, it
`is effective to increase the emphasis degree. As to a lens
`having a macro function capable of performing closeup, it is
`effective to increase the level division number of the AF
`evaluation value, and at the same time, it is also effective to
`increase the emphasis degree.

`0035) Similarly, as shown in Table 3, it is possible to
`express proper perspective by changing the level division
`number of the AF evaluation value in accordance with the
`pixel number of the LCD. In contrast to Table 3, it is also
`effective to increase the emphasis degree for the purpose of
`clarifying the perspective with the LCD having a small pixel
`number. By constituting the camera system Such that the
`user can set the level division number of the AF evaluation
`value and the emphasis degree, it is possible to provide the
`perspective desired by the user.
`0036). In the foregoing embodiments, the LCD is
`employed as the monitor of the electronic camera. The
`present invention, however, may be applied to an organic EL
