<p>PROBLEM TO BE SOLVED: To suppress a sense of discomfort on appearance of an image given to a user resulted from amplifying a signal based on electric charges obtained at each pixel arranged in a two-dimensional matrix shape.SOLUTION: When performing switching over of a gain of a column amplifier 103, according to a changed portion of the gain of the column amplifier 103, exposure control is performed by using both a gain of a digital gain amplifier 111 and exposure time so that the changed portion of the gain of the column amplifier 103 is cancelled out.</p> |
