Abstract:
1. A solid-state image sensor comprising: a pixel array; a color filter array complying with a Bayer array, the color filter array provided in correspondence to the pixel array; a first signal processor configured to process each of red-pixel and blue-pixel signals output from the pixel array; a second signal processor configured to process each of green-pixel signals output from the pixel array; and a control unit configured to control the pixel array, the first signal processor, and the second signal processor, wherein the control unit controls the pixel array to sequentially output pixel signals of a plurality of rows from the pixel array by selecting two rows at a time, the first signal processor performs a first signal process including an addition process for red-pixel signals output by performing twice the output of two rows from the pixel array, and an addition process for blue-pixel signals output by performing twice the output of two rows from the pixel array, the second signal processor performs a second signal process including an addition process for green-pixel signals output by performing twice the output of two rows from the pixel array, and the first signal process and the second signal process are performed at timings different from each other, a red-image signal and blue-image signal for a first field of the pixel array are generated while generating green-image signals for a second field of the pixel array subsequent to the first field, and a red-image signal and blue-image signal for the second field are generated while generating green-image signals for the first field.
