These parallel operations can reduce a waiting time from a time when the main unit 220 performs one AD conversion to the time when the main unit 220 performs the next AD conversion. This can reduce the period for AD conversion of signals to be output by all pixel circuits 10. An increased frame rate of an imaging apparatus can further be advanced.
This embodiment is not limited to this example. For example, it may be configured such that, during one frame period, pixels having a color filter for a first color can be connected, and pixels having a color filter for a second color cannot be connected. Describing with focus on pixels of one column having R and G color filters, the input unit 210 connects signal lines 14a, 14c connecting to pixels having a color filter for R that is the first color to the main unit 220. On the other hand, during the one frame period, the input unit 210 may not connect the signal lines 14b, 14d connecting to pixels having a color filter for G that is a second color to the main unit 220. In this configuration, signals of pixels to be input to the main unit 220 can be handled as signals corresponding to one color only. This advantageously can simplify correction of the AD conversion performed by the main unit 220 and simplify corrects after the AD conversion.
