`PERSONAL IMAGING SYSTEM WITH VIEWFINDER AND
`

`
`
`
`of which the following is a specification:
`
`FIELD OF THE INVENTION
`
`
`
`The present invention pertains generally to a new photographic or video means and
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`apparatus typically cor.1prising a hand-held portable electronic camera sy"Jtem with
`
`
`
`
`
`
`
`
`
`viewfinder mean,; and electronic pen-based annotation means.
`
`BACKGROUND OF THE INVENTION
`
`
`
`In photography (and in movie and video production). it is often desirable to cap
`
`
`
`
`
`
`
`
`
`ture events in a natural manner with minimal intervention or disturbance. In the
`
`
`
`present invention, the scenario to be considered is that of face-to-face conversation
`
`
`
`
`
`
`
`
`
`between two individuals, where one of the individuals wish� to make a.n annotated
`
`
`
`
`
`video diary of the conversation without disrupting the natural Oow of the conver
`
`
`
`
`
`o;ation. In this context. it is desirabl� to create a personal video diary or personal
`
`
`
`
`
`documentary, or to have some kind of personal photographic or videographic memory
`
`
`
`
`
`
`
`
`
`aid that forms the visual cquiva.lent of what the electronir organizers and personal
`
`
`
`
`
`digital a.qgistants do to help us remember textual or syntactic information.

`
`

`
`
`
`to the poiut of being negligible (e.g. no bigger than th,. , · ,-, of a typical cam-
`
`
`
`era viewfinder, for example), the very gestt;re of hringirg a device up to the eye is

`
`
`
`
`
`
`
`
`
`
`
`unnatural and attracts considerable attention, especially in establishments such as
`
`
`
`
`
`
`
`department stores where photography is often prohibited. However it is in these very
`
`
`
`
`
`
`
`
`
`
`
`establishments in which a customer may wish, for example, tu have a video record of
`
`
`
`
`
`
`
`
`
`the clerk's statement of the refund policy or the term.ci of a sale. Just as department
`
`
`
`
`
`
`
`stores often keep a video recording
`
`
`of all transactions (and often even a video record
`
`
`
`
`
`
`
`
`
`
`
`
`
`ing of all activity within the establishment, sometimes including a video recording of
`
`
`
`
`
`
`
`
`
`
`
`customers in the fitting rooms), the goal of the present invention is to assist, for ex
`
`
`
`ample, a customer who may wish to keep a video record of a transaction, interaction
`
`
`
`
`
`
`
`
`
`
`
`with a clerk. manager, refund cY.p)anatioo, or the like.
`
`
`Although
`
`
`
`beneath there exist a variety of covert cameras such a camera concealed
`
`
`
`
`
`the jewel of a necktie clip, cameras concealed in baseball caps, and cameras concealed
`
`
`
`
`
`
`
`
`
`
`
`in eyeglasses, these c3Illeras 1eud to produce inferior images, not just because of the
`
`
`
`
`
`
`
`technical limitations imposed by their small si�e, but, more importantly be•_:\use they
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`lack a viewfinder means (e.g. means of viewing the image to adjust ...;,mera a.ngle for
`
`
`
`best composition). Because llf the lack of viewfinder means, the subJect matter iis
`
`
`
`
`
`
`
`not necessarily centered well in the viewfinder, or even captured by the camera., and
`
`
`
`
`
`
`
`
`
`or for use in documentary thus these covert cameras are not well suited to personal
`
`
`
`
`
`
`
`
`
`memory assistant. a personal photographic/videographic
`
`
`
`A wearable camera system (called WearCam) has been proposed in, for example,
`
`
`
`
`
`IEEE Computer, Vol 30, No 2, or equivalently http://wearc:am.org/ieeecomputer.html
`
`
`
`
`
`
`
`
`
`(see also http://wearcomp.org/wearpubs.htm)). Unfortunately embodiments of the
`
`
`
`
`
`clothing, and such as special WearCa.m invention typically require special preparation
`
`
`
`
`
`
`
`
`
`
`
`
`
`special wiring of the body a-priori. Such systems will work for those dedicated to be

`
`
`
`
`
`
`
`
`
`
`
`
`ing constantly wired with various computational a.nd sensory apparatus incorporated
`
`
`
`into special clothing, but there are a good many individual!! who may wish to obtain
`
`
`
`
`
`
`
`
`
`the same convenience without a change of lifesty)L-.
`
`
`

`
`the device need not investigative documentary videos having very good compositi'>n:

`
`
`
`picture or video cannot readily determine whether or not the apparatus is in use

`
`
`
`
`
`
`
`
`
`
`recording. Just as department stores and the like often have dark domes on their
`
`
`
`
`
`ceilings, so that customers do not know whethf!r or not there are cameras in the
`
`
`
`
`
`
`
`domes ( or which ones have cameras and even which way the cameras are pointed if
`
`
`
`
`
`there are cameras in the domes), the proposed invention creates a situation in which a
`
`
`
`
`
`
`
`department store clerk or the like wiJJ not know whether or not a customer's personal
`
`
`
`
`

`
`
`
`
`
`A camera is built into the clipboard with the optical axis of the lens facing the
`
`
`
`
`
`<lirection from bottom to top of the clipboard, so that during normal face-to-face
`
`
`
`
`
`conversation, the person holding the clipboard will tend to point the camera at the
`
`
`
`
`
`
`
`
`
`other person while taking written notes of the conversation. In this manner, the
`
`
`
`
`
`
`
`
`
`
`
`intentionality ( whether or not the person taking written notes is intending to point
`
`
`
`
`
`the camera at the other person) is masked by the fact that the camera will aJways
`
`
`
`Thus the in the clipboard. of its placement be pointed at the other person by virtue
`
`
`
`
`
`
`
`
`
`
`
`camera lens opening need not necessarily be covert, and in fact, could be deliberately
`
`
`
`
`
`accentuateci (e.g. made more visible) if desired. To understand why it might be
`
`
`
`
`
`
`
`
`
`<lesirable to make it more visible, one can look to the earner� in department stores.
`
`
`

`
`
`
`
`
`which are often placed in hrge dark smoked plexiglass domes. In thi::i way they arP
`
`
`
`
`
`
`
`neither hidden nor visible, but rather, they serve as an uncertain deterrent b criminal
`
`
`
`
`
`
`
`
`
`
`
`conduct. \\ihile they could easily be hidden inside smoke cfetectors, ventillation slots,
`
`
`
`
`
`
`
`
`
`or small openings, the goal of the dome is to make the camera conceptually visible
`
`
`
`
`
`on the clipboard manner, a large lens opening yet completely bidden. In a similar
`
`
`
`
`
`
`
`
`
`may, at times, be desirable, so that the subject will be reminded that there could be a
`
`
`
`
`
`
`
`
`
`
`
`recording, but will be uncertain as to whether or not such a recording is actually taking
`
`
`
`
`
`place. Alternatively, a large dark shiny plexiglass strip. made from darkly smoked
`
`
`
`
`
`
`
`
`
`plexig]ass (typically 1cm high and 22cm across) is installed across the top of the
`
`
`
`clipboard, as a very subtle yet visible deterrent to criminai behaviour and disrespect.
`
`
`
`
`
`
`
`
`
`
`
`One or more miniature cameras are then installed behind the dark plexigla.ss, looking
`
`
`
`
`
`
`
`forward through it. In other embodiments, a camera is installed in a PDA, and then
`
`
`
`
`
`
`
`th� top of the PDA is covered with dark smoky plexiglass.
`
`
`
`The clipboard is fitted with an el�ctronir. rlisplay system which includes the capa
`
`
`
`
`
`
`
`
`
`bility of di5playing the imag" fro,, the camera, so that it can serve as a viewfinder
`
`
`
`
`
`
`
`
`
`constructed for aiming the camera at th,-:mhject. Moreover, the display is typically
`
`
`
`
`
`so that it is visibJ,-only to the user of the clipboard, or, at the very lea.st, so that the
`
`
`
`
`
`
`
`imhjcct ot the picture cannot readily see the display. Such concealment of the display

`
`
`
`
`
`
`
`Such honeycomb filters are common in phvtography, where they are placed over lights
`
`
`
`
`
`
`
`
`
`to make the light sourc�s behave more directionally. They a.re a.lso sometimes placed
`
`
`
`
`
`
`
`over traffic :ights where there is a wye intersection, so Lbat the lights can only be seen
`
`
`
`
`
`
`
`drivers on do not confuse from one direction, for example, so that the traffic lights

`
`
`
`
`
`
`

`SUMMARY OF THE INVENTION: Informal review of what the new
`
`inveiJtion does
`
`
`
`One aspect of the invention a.Jlows the user tn take note:; with pen and paper ( or
`
`
`
`pen and screen) and continuously record video together with the written notes. Even
`
`
`
`
`
`
`
`
`
`if there is insufficient memory lo capture a continuous video recording, the invention
`
`
`
`
`
`
`
`
`
`to produce a picture can be desigue<l so the user will always end up with the ability
`
`
`
`
`
`from something that wa.s seen a couple of minutes ago. This may be useful to everyone
`
`
`
`
`
`in the sense that we may not want to miss a great photo opportunity, a.nd often great
`
`
`
`photo opportunities only become known to us after we have had time to think ahout
`
`
`
`something we previously saw. At the very least, if for example. a departr�1ent store
`
`
`
`
`
`
`
`the customer may owner or manager becomes angry and imulting to the customer,
`
`
`
`
`
`
`retroactively
`
`
`
`record the event, by opening a circular buffer.
`
`
`
`
`
`there are a safety. Although Such an apparatus might also he of use in personal
`
`
`
`�owing number of vidro surveillance camf!ras installed in the environment, a.Jlege<lly
`
`IPR2021-00923
`Apple EX1004 Page 11
`
`
`
`
`for "public safety", there have been recent
`
`
`
`
`
`
`
`questions as to the true benefit of such
`
`
`
`
`
`centralized surveil1ance infrastructures. Most notably there have been several exam
`
`
`
`
`
`
`
`
`
`ples in which such centralized infrastructure has been abused by the owners of it ( as
`
`
`
`
`
`
`
`
`
`
`
`in roundups and detainment of peaceful demoostrators). Moreover, "public safety"
`
`
`
`
`
`systems may fail to protect individuals against crimes committed by members of thf"
`
`
`
`
`
`
`
`
`
`
`
`organizations that installed the systems. Accordingly, embodiments of the invention
`
`
`
`
`
`
`
`
`
`often implement the storage and retrieval of images hy transmitting and recording
`
`
`
`
`
`
`
`images at one or more remote locations. In one embodiment of the invention, images
`
`
`
`
`
`
`
`
`
`were transmitted and recor,fod in different countries, so that they would be difficult
`
`
`
`
`
`
`
`
`
`
`
`to destroy, in the event that the perpetrator of a crime or other misconduct might
`
`wish to do so.
`
`
`
`
`
`
`
`
`
`
`
`The invc�ntion allows images to be captured iu a natural manner, without giving
`
`
`
`
`
`an unusual appearance to others (such as m abusive official).
`
`
`
`
`
`
`
`
`
`
`
`Moreover� a.s an artistic toot of personal expression, the apparatus allows the user
`
`
`
`
`
`
`
`to record, f,.om a new perspective, experiences that. have b'---eh <lifccnlt to so record
`
`
`
`
`
`
`
`
`
`in the past. For example, a customer might be tt.ble lo record an argument with a
`
`
`
`
`
`
`
`fraudulent business owner from a very close camera angle. This is possible because
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`a cliphoard may be extended outward Loward the person without violating personal
`
`
`
`space in th,� same way as might be necessary to do the same with a camera. hid
`
`
`
`den in a tit. clip, baseball cap, or sungfasses. Since a clipboard may extend outward
`
`
`
`
`
`
`
`from the body, it may be placed closer lo the subject than the normal eye viewpoint
`
`
`
`
`
`
`
`in normal face-to-face conversation. As a result, the camera can capture a very
`
`
`
`
`
`
`
`close-up vit!W of the subject. Such a view is often more desirable than the view ol>
`
`
`
`
`
`tainable fro:-i1 a telephoto lens located in eyeglasses (e.g. te)eph'lto embodiment o! th�
`
`

`
`
`
`
`
`ful compoeition, from underneath the subject's face, and is therefore most suitable.
