Abstract
For each of the signal corresponding to a signal of a photoelectric converting unit being only a part of an effective pixel and the signal corresponding to a signal obtained by adding signals of a plurality of photoelectric converting units, the difference corresponding to the signal corresponding to the signal obtained by adding the signals of the plurality of photoelectric converting units of a light-shielded pixel.
Claims20
An image pickup apparatus comprising:
- a plurality of pixels arranged in a plurality of rows, that each has one microlens and a plurality of photoelectric converting units disposed to correspond to each one of the microlenses, and that outputs a signal by each row, wherein
- a first row being a part of the plurality of rows includes an effective pixel having the plurality of photoelectric converting units to which the light transmitted through the one microlens enters,
- a second row being other part of the plurality of rows includes a light-shielded pixel having the plurality of photoelectric converting units shielded from light, and does not include the effective pixel,
- the effective pixel in the first row outputs a first signal based on a signal generated by the photoelectric converting unit being only a part of the plurality of photoelectric converting units and outputs a second signal based on a signal obtained by adding signals generated by the plurality of photoelectric converting units,
- the light-shielded pixel in the second row outputs a third signal based on a signal obtained by adding signals generated by the plurality of photoelectric converting units, and
- the image pickup apparatus further comprises a signal processing unit configured to obtain a first difference between a signal based on the first signal and a signal based on the third signal and obtain a second difference between a signal based on the second signal and the signal based on the third signal.
