Abstract:
1. An image pickup device comprising: an image capturing unit that includes a solid-state image pickup device having a plurality of pixels arrayed in a matrix form, the image capturing unit sequentially outputting a plurality of image capturing signals each of which corresponds to one of a plurality of pixel signals output from the solid-state image pickup device; and an evaluation value generating unit to which the plurality of image capturing signals output from the image capturing unit are sequentially input, the evaluation value generating unit generating an evaluation value based on the input image capturing signals, wherein the evaluation value generating unit comprises: the evaluation value generating unit sequentially inputs signals corresponding to the plurality of image capturing signals sequentially output from the image capturing unit as input signals of the horizontal and vertical decimation units, the evaluation value generating unit sequentially inputs the image capturing signals obtained through the decimation process performed in the row direction by the horizontal decimation unit as input signals of the vertical evaluation value generating unit, and the evaluation value generating unit sequentially inputs the image capturing signals obtained through the decimation process performed in the column direction by the vertical decimation unit as input signals of the horizontal evaluation value generating unit.
