Abstract

Abstract The present invention comprises means for the instantaneous review of photographs as they are taken by a regular film camera. It comprises four basic components: 1) an image sensor means, preferably comprising a charge-coupled device ("CCD"), that produces a signal corresponding to the image sensed, disposed such that it senses an image corresponding to the image seen by a camera's objective lens; 2) a shutter release sensor means, preferably incorporated it the camera's shutter release, that indicates when a photograph is being taken; 3) an image processor means that processes the signal produced by the image sensor means; and 4) a display means, preferably a liquid crystal display ("LCD"), that displays the image seen by the image sensor means at the time the shutter release sensor means indicated that a photograph was being taken.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 132 words
Image review means for displaying an image corresponding to a photograph taken by a camera having an objective lens means, a back, a first flash mount means, and a first flash triggering means, said image review means comprising: flash mount attachment means for removably attaching said image review means to the first flash mount means of the camera; image sensor means capable of generating a signal corresponding to an image sensed by said image sensor means, said image sensor means orientable such that the image sensed corresponds substantially to the image seen through the objective lens means of the camera; and image display means capable of displaying an image corresponding to the signal generated by the image sensor means at the time the first flash triggering means of the camera is activated.
Claim 2
Dependent Claim 132 words
Image review means for displaying an image corresponding to a photograph taken by a camera having an objective lens means, a back, a first flash mount means, and a first flash triggering means, said image review means comprising: flash mount attachment means for removably attaching said image review means to the first flash mount means of the camera; image sensor means capable of generating a signal corresponding to an image sensed by said image sensor means, said image sensor means orientable such that the image sensed corresponds substantially to the image seen through the objective lens means of the camera; and image display means capable of displaying an image corresponding to the signal generated by the image sensor means at the time the first flash triggering means of the camera is activated.
Claim 3
Dependent Claim 39 words
The image review means of claim 1 further comprising memory means capable of storing a signal corresponding to the signal generated by the image sensor means at the time the first flash triggering means of the camera is activated.
Claim 4
Dependent Claim 18 words
The image review means of claim 1 wherein the image display means comprises a liquid crystal display means.
Claim 5
Dependent Claim 20 words
The image review means of claim 1 wherein the image display means is moveably connected to the image sensor means.
Claim 6
Dependent Claim 24 words
The image review means of claim 4 wherein the image display means is connected to the image sensor means by a ribbon cable means.
Claim 7
Dependent Claim 21 words
The image review means of claim 4 wherein the image display means is removably attachable to the back of said camera.
Claim 8
Dependent Claim 20 words
The image review means of claim 4 wherein the image display means is pivotably connected to the image sensor means.
Claim 9
Dependent Claim 46 words
The image review means of claim 1 wherein the image sensor means further comprises miniature zoom lens that allows a field of view of the image sensor means to be adjusted to correspond to a field of view of the objective lens means of the camera.
Claim 10
Dependent Claim 51 words
The image review means of claim 1 further comprising second flash mount means allowing a flash to be mounted to the image review means and second flash triggering means for triggering a flash mounted to said second flash mount means when said first flash triggering means of said camera is triggered.
Claim 11
Dependent Claim 50 words
The image review means of claim 1 wherein the image display means comprises inherent memory characteristics such that it is capable of displaying and retaining an image corresponding to the signal generated by the image sensor means at the time the first flash triggering means of the camera is activated.
