Abstract

Abstract In a photoelectric transducer device such as a solid state image pick-up device or sensor having a great number of minute photoelectric transducer elements with their image-receiving surfaces of certain shape arranged in a one-dimensional or two-dimensional manner so that brightness informations of the various individual sections of the object image are sensed by the respective photoelectric transducer elements which then produce outputs in the form of time-sequential signals, the above-described shape of the image-receiving surface area of each of the minute photoelectric transducer elements is made to be such that, as the distance from the center of the image receiving area toward the margin increases, the proportion of the area of a progressively farther concentric zone of the same width is decreased. The shape takes such a form or such characteristics as to be represented by a sampling function or other analogous functions with respect to the scanning direction of the image pick-up device.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 100 words
An image pick-up device comprising: (a) a color separation optical system which separates an incident light beam into a plurality of light beams having different colors; and (b) a plurality of solid state image pick-up devices each arranged so as to receive the light beams separated by the color separation optical system, and each having a plurality of photoelectric elements arranged in a matrix pattern in rows and columns, each photoelectric element having a light receiving surface, whereby light receiving surface of adjacent photoelectric elements form an overlapping zone at least in one direction along the row or the column.
Claim 2
Dependent Claim 100 words
An image pick-up device comprising: (a) a color separation optical system which separates an incident light beam into a plurality of light beams having different colors; and (b) a plurality of solid state image pick-up devices each arranged so as to receive the light beams separated by the color separation optical system, and each having a plurality of photoelectric elements arranged in a matrix pattern in rows and columns, each photoelectric element having a light receiving surface, whereby light receiving surface of adjacent photoelectric elements form an overlapping zone at least in one direction along the row or the column.
Claim 3
Dependent Claim 19 words
An image pick-up device according to claim 1, in which the color separation optical system includes a dichroic prism.
Claim 4
Dependent Claim 47 words
An image pick-up device according to claim 1, in which the color separation optical system and individual solid state image pick-up devices are so arranged to assure that corresponding images fall on photoelectric elements positioned at a predetermined same matrix position within the solid image pick-up device.
Claim 5
Dependent Claim 53 words
A solid state image pick-up device comprising: a plurality of photoelectric elements arranged in a matrix pattern in row-orientation and column-orientation, each of said elements having a light receiving surface, and light receiving surfaces of photoelectric elements adjacent each other in row-orientation and column-orientation having a mutually overlaping zone in row-orientation and column-orientation.
Claim 6
Dependent Claim 53 words
A solid state image pick-up device comprising: a plurality of photoelectric elements arranged in a matrix pattern in row-orientation and column-orientation, each of said elements having a light receiving surface, and light receiving surfaces of photoelectric elements adjacent each other in row-orientation and column-orientation having a mutually overlaping zone in row-orientation and column-orientation.
