IMAGING APPARATUS AND IMAGING SYSTEM

摘要

Because a conventionally known imaging apparatus includes a buffer element for each signal processing circuit, the number of buffer elements increases in proportion to the number of signal processing circuits. The delayed supply of a drive signal within a group of a plurality of signal processing circuits may require the operation timing margin to be set longer. In other words, the operational speed is hard to increase. First buffer circuits connected in series and second buffer circuits connected in parallel with the first buffer circuits are provided, and one second buffer circuit supplies a drive signal to a plurality of signal processing units.

1. An imaging apparatus comprising:
a pixel array; a plurality of signal processing units each of which is provided correspondingly to a column of the pixel array; and a drive signal transmitting unit which transmits a drive signal that drives the signal processing units, wherein the drive signal transmitting unit includes a plurality of first buffer circuits and a plurality of second buffer circuits; an output terminal of one of the first buffer circuits is connected to input terminals of another one of the first buffer circuits and one of the second buffer circuits; and the second buffer circuit supplies the drive signal of the plurality of signal processing units.
