    Abstract: An imaging device includes a plurality of pixels arranged to form a plurality of rows and a plurality of columns and each including a photoelectric converter, an accumulation time controller that controls accumulation time of the plurality of pixels, and an amplifier that amp1ifies a signal based on charge generated by the photoelectric converter. The plurality of pixels are divided into a plurality of pixel blocks each including at least two of the plurality of pixels, the accumulation time controller is configured to control the accumulation time individually for the plurality of pixel blocks, and the amplifier is configured to output, for one pixel block of the plurality of blocks, a plurality of signals which are amp1ified at different gains and correspond to accumulation time of a common frame.

    Abstract: A focus detection apparatus that performs a first determination for determining whether a signal level indicating an amount of the electric charges accumulated in the photoelectric conversion element has reached a lower threshold, and a second determination for determining whether the signal level has reached a higher second. During a time period from when it is determined that the signal level has reached the lower threshold to when it is determined that the signal level has reached the higher threshold, the second determination is performed at a shorter time interval if an elapsed time from when the accumulation of the electric charges is started to when it is determined that the signal level has reached the first threshold is shorter than a reference time, and at a longer time interval if the elapsed time is longer than the reference time.
