Abstract
Abstract A still image pickup device is provided with an image pickup element positioned on an image plane on which an object image is focused in a detection area and having an image pickup surface smaller than the detection area, for converting a part of the object image into an electrical image signal; a moving device for two-dimensionally moving the image pickup surface on the image plane; an input device for entering the image signal supplied from the image pickup element; and a control unit for controlling the moving device to move the image pickup surface based on the entry of the image signal by the input device, wherein the image pickup element converts another part of the object image into another image signal at a position to which the image pickup surface is moved and the input device enters the above-mentioned another image signal.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
208 words
An apparatus comprising: means for forming an object image on a predetermined plane; image pickup means having an image pickup surface positioned substantially on said predetermined plane, said image pickup means producing an electrical image signal from light incident thereon; moving means for two-dimensionally moving said image pickup means along said predetermined plane in an image detection area substantially larger than the area of said image pickup surface; memory means; processing means for processing said electrical image signal and storing the processed signal in said memory means; control means for controlling said moving means to move and stop said image pickup means in said detection area so as to position and stop said image pickup surface successively in a plurality of non-overlapping positions in said detection area, and for controlling said image pickup means and said processing means such that said image pickup means produces an electrical image signal at each of said plurality of positions and said processing means processes each electrical image signal and stores the corresponding processed signal in said memory means; and synthesizing means for synthesizing an image signal representing the portion of the object image corresponding to said plurality of positions on the basis of the processed signals stored in said memory means.
Claim 2
Independent Claim
208 words
An apparatus comprising: means for forming an object image on a predetermined plane; image pickup means having an image pickup surface positioned substantially on said predetermined plane, said image pickup means producing an electrical image signal from light incident thereon; moving means for two-dimensionally moving said image pickup means along said predetermined plane in an image detection area substantially larger than the area of said image pickup surface; memory means; processing means for processing said electrical image signal and storing the processed signal in said memory means; control means for controlling said moving means to move and stop said image pickup means in said detection area so as to position and stop said image pickup surface successively in a plurality of non-overlapping positions in said detection area, and for controlling said image pickup means and said processing means such that said image pickup means produces an electrical image signal at each of said plurality of positions and said processing means processes each electrical image signal and stores the corresponding processed signal in said memory means; and synthesizing means for synthesizing an image signal representing the portion of the object image corresponding to said plurality of positions on the basis of the processed signals stored in said memory means.
Claim 3
Dependent Claim
39 words
An apparatus according to claim 1, wherein the number of said positions is odd, and said control means controls said moving means such that said image pickup surface is first positioned at a central area in said detecting area.
