ABSTRACT:
A column A/D converter includes two column A/D converting elements. Each of the column A/D converting elements is operable to divide a pixel signal read out from a pixel array into two blocks i.e. an upper block constituted of upper two bit data, and a lower block constituted of lower two bit data, and sequentially perform A/D conversion with respect to the blocks in the unit of one horizontal scanning period. A controller causes each of the column A/D converting elements to concurrently perform A/D conversion with respect to different blocks of pixel signals at different rows.
