IMAGE CAPTURING DEVICE, CONTROL METHOD THEREOF AND DATA MEDIUM Russian patent published in 2012 - IPC G03B13/36 G02B7/28 H04N5/232 

FIELD: physics.

SUBSTANCE: image capturing device has an image sensor for capturing an image signal generated by a photographic optical system which includes a focusing lens, a detecting unit for detecting the object region based on the image signal captured by said image sensor, a first generating unit for generating first information associated with the focusing state of the photographic optical system based on the image signal captured by said image sensor, a second generating unit for dividing optical flux from the object into two in order to generate two images and generate second information associated with the value of relative positional shift between the two images, and a control unit for controlling the execution of at least one of first focusing control using first information and second focusing control using second information. The control unit is configured to restrict execution of second focusing control when said detecting unit detects an object region.

EFFECT: ensuring stable focusing on an object at a high rate without creating inconvenience for the photographer.
