Document Type and Number:
Japanese Patent JP2022184137
Kind Code:
A
Abstract:
To improve focusing accuracy based on auto-focusing in an image sensor in which an exposure condition can be set for each area.SOLUTION: Auto-focusing of an imaging apparatus in which a condition of exposure can be set for each partial area of a light receiving surface of an image sensor is performed. A first partial area in which imaging is performed using a first exposure condition and a second partial area which is adjacent to the first partial area and in which imaging is performed using a second exposure condition different from the first exposure condition are set on the light receiving surface. A third partial area which does not include an exposure-level difference which is a boundary portion between the first partial area and the secondary partial area is set as an area used for the auto-focusing. The auto-focusing of the imaging apparatus is controlled according to contrast of an image based on an image signal of the third partial area.SELECTED DRAWING: Figure 7
