Solid-state imaging apparatus and imaging system using the same

摘要

Provided is a solid-state imaging apparatus including: imaging pixels each configured to generate an imaging signal through photoelectric conversion; focus detection pixels each configured to generate a focusing signal through photoelectric conversion; and an adding unit configured to add the imaging signals generated by the imaging pixels to generate an added imaging signal, and configured to add the focusing signals generated by the focus detection pixels to generate an added focusing signal, in which a number of the focusing signals to be used by the adding unit to generate one added focusing signal is larger than a number of the imaging signals to be used by the adding unit to generate one added imaging signal, and operation for outputting the added focusing signal and operation for outputting each of the focusing signals without adding are selectively carried out.

1. A solid-state imaging apparatus, comprising:
a plurality of imaging pixels each configured to generate, through photoelectric conversion, electric charge as an imaging signal; a plurality of first focus detection pixels each configured to generate, through photoelectric conversion, electric charge as at least a first focusing signal among first and second focusing signals used for a phase difference focus detection; and an adding unit configured to add the electric charge generated by the plurality of imaging pixels to generate an added imaging signal, and configured to add the electric charge generated by the plurality of first focus detection pixels to generate a first added focusing signal, wherein a number of the first focus detection pixels to be used for generating one first added focusing signal by the adding unit is larger than a number of the imaging pixels to be used for generating one added imaging signal by the adding unit, and wherein an operation for outputting the first added focusing signal and an operation for outputting each of the first focusing signals without adding are selectively carried out.
