[Means for solving problems]
The present invention for solving the above problems is a solid-state image sensor having photoelectric conversion pixels arranged in two dimensions and randomly accessing the photoelectric conversion pixels, and the first skip for reading out arbitrarily designated pixels. It has a read mode and a second skip read mode for reading an image area smaller than the image frame read in the first skip read mode , and the number of pixels read in the first and second skip read modes is made equal. is there.
すなわち、本発明においては、受光部にランダムアクセス可能な固体撮像装置を用いて、画像読み出しエリアをスキップ読み出し及びブロック読み出しを用いて可変することで、センサチップ単体で電子ズーム処理を行う。また、読み出し画像領域を変えても読み出し画素数が変わらないようにしている。
That is, in the present invention, the electronic zoom process is performed by the sensor chip alone by changing the image reading area by using skip reading and block reading using a solid-state image sensor that can randomly access the light receiving unit. Further, the number of read pixels does not change even if the read image area is changed.
