`
` High-Resolution Color CCD for Consumer Digital
`Still Cameras Supports VGA Resolution Moving
`Picture Imaging
`
`ICX652CQZ
`Diagonal 9.321 mm (Type 1/1.7) 13.69M-Effective Pixel
`
`In addition to the existing needs for even higher resolution in compact
`consumer digital still cameras, there are now increasing needs for
`improved high-ISO sensitivity and higher dynamic range.
`Sony has now developed the ICX652CQZ diagonal 9.321 mm (Type
`1/1.7) 13.69M-effective pixel interline CCD that is appropriate for high-
`end models of compact consumer digital still cameras.
`In this device, Sony used unique fine fabrication technology to reduce the
`unit pixel size to 1.75 μm, increase the pixel count, and achieve still
`imaging with 13.69M pixels.
`Furthermore, this device includes a horizontal and vertical pixel addition
`function that can add two vertical and two horizontal pixels to achieve
`continuous high-sensitivity still imaging equivalent to a 3.42M-pixel
`sensor.
`The ICX652CQZ also provides high picture quality VGA resolution
`moving image capture at 30 frame/s.
`
` ICX652CQZ
`■ Diagonal 9.321 mm (Type 1/1.7) 13.69M effective pixels
`■ Pixel size: 1.75 μm unit pixel
`■ Four-field readout
`■ Horizontal divided into fourths output
`■ Horizontal 3-phase drive
`
`
`
`The ICX652CQZ is a diagonal 9.321 mm (Type 1/1.7) 13.69M-effective pixel CCD that was
`designed for high-resolution consumer digital still cameras. It can capture high-resolution
`images by using a mechanical shutter. The ICX652CQZ is an increased pixel count version
`of Sony's existing ICX612CQZ (diagonal 9.299 mm (Type 1/1.7) 12.19M effective pixels) and
`allows customers to implement 13.5M-pixel digital still cameras with no changes to the
`optical system from existing cameras using the ICX612CQZ. Table 1 lists the device structure
`and table 2 lists the image sensor characteristics.
` The Industry’s Highest Pixel Count
`The desires for higher pixel counts are becoming stronger in the consumer digital still
`camera market. Sony has now released a Type 1/1.7 13.69M-effective pixel CCD that
`provides the industry's highest pixel count in a consumer digital still camera.
` Horizontal Divided into Fourths Output
`The usual way to maintain the frame rate as the pixel count increases is to increase the drive
`frequency. That does, however, have the problem that power consumption increases as well.
`In the ICX652CQZ, Sony developed a new horizontal divided into fourths output method (see
`figure 1) that uses addition to reduce the number of horizontal outputs to 1/4 the full number
`and achieves 30 frame/s VGA operation at the same 38 MHz drive frequency as the existing
`Sony ICX612CQZ.
` High Sensitivity, High-Speed Still Imaging
`The ICX652CQZ provides a high-sensitivity, high-speed output frame readout mode
`(horizontal and vertical 2 × 2 addition) to respond to the demands for higher ISOs in still
`imaging and improved continuous shooting functionality. (See table 2.)
`In this mode, the ICX652CQZ implements both a horizontal 2-pixel addition function for the
`horizontal divided into fourths method and a vertical register vertical 2-pixel addition function
`and outputs high-sensitivity (due to 4-pixel addition) 3.42M-pixel equivalent still images at
`6.1 frame/s.
` Low Smear Characteristics
`Improvement in image smear, which is a characteristic phenomenon in CCDs that occurs
`during moving picture imaging, are now strongly desired. To respond to this need, Sony has

`shielding film thinner and succeeded in reducing smear component admixture to the vertical
`registers. The use of this technology allowed Sony to improve the smear characteristics by

`approximately 4 dB from the existing Sony ICX636 (a 1.75 μm unit cell device), thus
`achieving a -89 dB level in frame readout mode. (See table 2.)

`•••• Mr. Akahoshi ••••
`To respond to market desires for higher pixel counts and further
`miniaturization, we developed a Type 1/1.7 13.69M-pixel CCD.
`This device provides high-sensitivity still imaging in frame readout mode
`(horizontal and vertical 2 × 2 addition).
`I strongly recommend that you consider using this device, which we
`developed using a wide range of the latest technologies.
