Abstract:
1. An image pickup apparatus including a pixel section formed by arranging a plurality of pixels in a two-dimensional matrix form, each pixel including a first pixel having a first sensitivity to an amount of entered light, and a second pixel having a second sensitivity which is higher than the first sensitivity, the image pickup apparatus comprising: a first signal processing unit and a second signal processing unit each configured to perform analog-to-digital conversion processing on a pixel signal read from each pixel of the pixel section to thereby obtain image data; an interconnection layer including a plurality of interconnections for transferring the pixel signal to said first signal processing unit and said second signal processing unit; and a read-out unit configured to, when the pixel signal is read out from the first pixel, transfer the pixel signal to said first signal processing unit through one interconnection of said interconnection layer, and when the pixel signal is read out from the second pixel, transfer the pixel signal to said second signal processing unit through another interconnection of said interconnection layer, wherein in a case where the image pickup apparatus is to perform shooting with a predetermined dynamic range, said first signal processing unit and said second signal processing unit are both powered on, and in a non-recording operation state in which the image pickup apparatus is powered on but a shooting operation is not performed by the image pickup apparatus, said second signal processing unit is powered off whereas said first signal processing unit is powered on.
