Title:
IMAGING APPARATUS AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/092731
Kind Code:
A1
Abstract:
An imaging unit of an imaging apparatus comprises an imaging element having a plurality of photoelectric conversion units that converts an optical image of an object formed by an imaging optical system into an image signal. A focus detection unit reads out a plurality of image signals that has been pupil-split by the imaging element and performs focus detection. If an accumulation time of the imaging element or a signal-to-noise ratio of the image signal changes, a system control unit controls a readout line that obtains the image signals in a focus detection region with respect to the imaging unit to change the readout line of focus detection pixels in accordance with an accumulation time or a sensitivity setting of the imaging element. In a low shutter speed and a high sensitivity, the readout control of the image signal is performed by reducing the number of readout lines.
