IMAGING DEVICE, FOCUS DETECTING DEVICE, AND IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent a pixel output readout circuit of an imaging device from becoming complex. SOLUTION: The imaging device is constituted by arraying pixels for imaging each having a photoelectric conversion unit and pixels for focus detection each having a pair of a first photoelectric conversion unit and a second photoelectric conversion unit in two dimensions. The imaging device has an output unit which outputs a signal, generated by adding together outputs of first photoelectric conversion units 322 and 332 of a first pixel 321 for focus detection and a second pixel 331 for focus detection which are adjacent to each other among the plurality of pixels for focus detection from the first pixel 321 for focus detection and also outputs a signal generated by adding together outputs of second photoelectric conversion units 323 and 333 from the second pixel 331 for focus detection.
