Abstract:
1. An image capture apparatus comprising: an image sensor having a pixel unit which photo-electrically converts an object image; a pixel signal readout unit configured to read out a signal for image forming and a signal for focus detection from the pixel unit; a general control and calculating unit configured to control the readout unit to change a ratio of a number of frames in the first readout mode and a number of frames in the second readout mode, wherein a first readout mode is a mode comprising reading out both the signal for focus detection and the signal for image forming from the pixel unit and a second readout mode is a mode comprising reading out only the signal for image forming from the pixel unit-without reading out the signal for focus detection, a phase difference calculation unit configured to determine based on the signal for focus detection whether the object image is in an in-focus state; and a temperature detection unit configured to detect a temperature of the image capture apparatus, wherein said general control and calculating unit is configured to control to read out the signal from the pixel unit in the second readout mode from a frame next to the frame in which the in-focus state has been determined by said determination unit, and to change the number of frames to read out the signal from the pixel unit in the second readout mode based on the temperature detected by said temperature detection unit, the general control and calculating unit further configured to increase the number of frames when the temperature detected by said temperature detection unit rises.
