IMAGING ELEMENT, IMAGING APPARATUS, ITS CONTROL METHOD, AND CONTROL PROGRAM

摘要

An imaging element having a layered structure including a first chip having a pixel portion in which pixels for photoelectrically converting an optical image of an object and generating a pixel signal are arranged two-dimensionally and a second chip in which a drive means of the pixel portion is arranged, and having a first output path to output the pixel signals of at least a first pixel group in the pixel portion and a second output path to output the pixel signals of a second pixel group, comprises the a conversion means for converting the pixel signals of the first and second output paths into digital signals and a control information generation means for generating control information of a photographing operation of the object by using the digital signal converted by the conversion means, wherein at least a part of the conversion means is arranged in the first chip.

主权项

1. An imaging element having a stacked structure which includes a first chip having a pixel portion in which pixels each for photoelectrically converting an optical image of an object and generating a pixel signal are arranged in a matrix form and a second chip having a first output path for outputting the pixel signals of a first pixel group in the pixel portion and a second output path for outputting the pixel signals of a second pixel group, the imaging element comprising:
a conversion unit configured to convert the pixel signals from the first output path and the second output path into digital signals, the conversion unit comprising a first conversion unit configured to convert the pixel signal from the first output path into the digital signal and a second conversion unit configured to convert the pixel signal from the second output path into the digital signal; and a drive unit configured to drive the pixel portion, wherein a conversion condition of the first conversion unit and a conversion condition of the second conversion unit differ.
