Abstract
An image pickup apparatus including: an image pickup device including a pixel region in which image pixels corresponding to microlenses are arrayed in a matrix, each of the image pixels being divided into a plurality of focus detection pixels configured to generate respective photoelectric conversion signals; and a control circuit configured to control a cycle in a column direction of first rows in which photoelectric conversion signals in an image pixel are added up to generate an image pixel signal, and second rows in which both of a pair of the focus detection pixel signals or one of the pair of the focus detection pixel signals and the image pixel signal are generated and read, in a frame is provided.

An image pickup apparatus comprising:
- an image pickup device including a pixel region in which image pixels corresponding to microlenses are arrayed in a matrix, each of the image pixels being divided into a plurality of focus detection pixels configured to perform photoelectric conversion of a light flux passing through a plurality of regions resulting from division of an exit pupil of a shooting optical system, to generate respective photoelectric conversion signals, each of the image pixels generating an image pixel signal and focus detection pixel signals based on the photoelectric conversion signals;
- and
- a control circuit configured to control a cycle in a column direction of first rows in which first reading is performed, the first reading including adding up all the photoelectric conversion signals generated in one of the image pixels to generate the image pixel signal and reading the generated image pixel signal only, and second rows in which second reading or third reading is performed, the second reading including generating both of a pair of the focus detection pixel signals in a pupil division direction based on the photoelectric conversion signals and reading both of the pair of the focus detection pixel signals, the third reading including generating and reading one of the pair of the focus detection pixel signals and the image pixel signal, in one frame.
A method for controlling an image pickup apparatus including an image pickup device including a pixel region in which image pixels corresponding to microlenses are arrayed in a matrix, each of the image pixels being divided into a plurality of focus detection pixels configured to perform photoelectric conversion of a light flux passing through a plurality of regions resulting from division of an exit pupil of a shooting optical system, to generate respective photoelectric conversion signals, each of the image pixels generating an image pixel signal and focus detection pixel signals based on the photoelectric conversion signals, the method comprising:
- performing first reading including adding up all the photoelectric conversion signals generated in one of the image pixels to generate the image pixel signal and reading the generated image pixel signal only, in first rows;
- performing second reading or third reading, the second reading including generating both of a pair of the focus detection pixel signals in a pupil division direction based on the photoelectric conversion signals and reading both of the pair of the focus detection pixel signals, the third reading including generating and reading one of the pair of the focus detection pixel signals and the image pixel signal, in second rows;
- and
- controlling a cycle in a column direction of the first rows and the second rows in one frame.
A computer-readable non-transitory recording medium recording a program for causing a computer to control an image pickup apparatus including an image pickup device including a pixel region in which image pixels corresponding to microlenses are arrayed in a matrix, each of the image pixels being divided into a plurality of focus detection pixels configured to perform photoelectric conversion of a light flux passing through a plurality of regions resulting from division of an exit pupil of a shooting optical system, to generate respective photoelectric conversion signals, each of the image pixels generating an image pixel signal and focus detection pixel signals based on the photoelectric conversion signals, the program causing the computer to:
- perform first reading including adding up all the photoelectric conversion signals generated in one of the image pixels to generate the image pixel signal and reading the generated image pixel signal only, in first rows;
- perform second reading or third reading, the second reading including generating both of a pair of the focus detection pixel signals in a pupil division direction based on the photoelectric conversion signals and reading both of the pair of the focus detection pixel signals, the third reading including generating and reading one of the pair of the focus detection pixel signals and the image pixel signal, in second rows;
- and
- control a cycle in a column direction of the first rows and the second rows in one frame.
