Abstract

According to an embodiment of the present technology, there is provided a processing apparatus or a program causing a computer to execute as a processing apparatus including a camera shake correction control unit configured to, based on a focus area in which pixel values of phase difference pixels is used in focus control among areas of an image output by an image sensor, control camera shake correction performed by changing a relative positional relationship in a direction perpendicular to an optical axis in an optical system between the image sensor that includes as some of pixels, phase difference pixels that are pixels for obtaining phase difference information to be used in focus control based on a phase difference method, and the optical system, which is for forming an image on the image sensor from light from an object.

Description

technical field [0001] The present technology relates to a processing device, a processing method, and a program. More specifically, the present technology relates to, for example, a processing device, a processing method, and a program that enable quick and accurate autofocus while also allowing camera shake correction to function as much as possible. Background technique [0002] For example, in digital (still) cameras such as compact cameras, mirrorless cameras, and single-lens reflex cameras, examples of autofocus (hereinafter also referred to as "AF") that automatically set the in-focus state to the in-focus state include the contrast method and difference method. [0003] In the contrast method, focus control for driving a focus lens is performed such that the contrast of an image captured by a digital camera is at a maximum. [0004] In such a contrast method, since the contrast of an image used in focus control can be obtained from an image captured by a digital ca...
