Patent ID: 8654224

Claim:
A composite imaging element comprising: a first imaging element including a plurality of first opto-electrical conversion parts configured to receive light having a first basic color and a second basic color different from the first basic color, the first opto-electrical conversion parts being further configured to convert light received by the first opto-electrical conversion parts into a first electrical signal, a first light receiving surface formed by the opto-electrical conversion parts, a plurality of first separation regions provided between the first opto-electrical conversion parts, the plurality of first separation regions forming boundaries between adjacent the first opto-electrical conversion parts and a plurality of first circuit parts through which the first electrical signal is transmitted, the first circuit parts disposed at positions that overlap the first separation regions when viewed from a first direction, the first direction substantially perpendicular to the first light receiving surface; and a second imaging element including a plurality of second opto-electrical conversion parts configured to receive light emitted from the first opto-electrical conversion parts and convert light received by the second opto-electrical conversion parts into a second electrical signal, a plurality of second separation regions provided between the second opto-electrical conversion parts, the plurality of second separation regions forming boundaries between adjacent the second opto-electrical conversion parts and a plurality of second circuit parts disposed at positions that overlap the second separation regions when viewed from the first direction, the second electrical signal being transmitted through the second circuit part; wherein: the first opto-electrical conversion parts are disposed at a first pitch, the second opto-electrical conversion parts are disposed at a second pitch, the second pitch greater than the first pitch, and a portion of the first circuit parts are disposed at positions that do not overlap the second circuit parts when viewed from the first direction.
