Patent ID: 8218050

Claim:
A solid-state imaging apparatus comprising: a plurality of pixels arranged in a matrix in one or more rows and one or more columns, wherein each pixel includes a photoelectric conversion element converting light into an electric charge and outputs a read out signal based on the electric charge converted by the photoelectric conversion element; a plurality of capacitors arranged correspondingly to each of the columns of the plurality of pixels to hold the signal output from the plurality of pixels; and a horizontal scanning circuit for sequentially reading out the signals held by the plurality of capacitors, by sequentially transferring data pulse in response to a clock pulse, wherein the horizontal scanning circuit comprises a mask signal input portion to which a mask signal is input, and when the plurality of pixels output the signals to the plurality of capacitors during a horizontal scan time period in which the horizontal scanning circuit reads out the signal of one row of the pixels, and the read out signals change, the mask signal is input to the mask signal input portion, and a transfer of the data pulse is disabled irrespective of the input of the clock pulse.
