    Abstract: An image sensor includes: a first pixel having a first photoelectric conversion unit that photoelectrically converts light having entered therein, and a first light blocking unit that blocks a part of light about to enter the first photoelectric conversion unit; and a second pixel having a second photoelectric conversion unit that photoelectrically converts light having entered therein and a second light blocking unit that blocks a part of light about to enter the second photoelectric conversion unit, wherein: the first photoelectric conversion unit and the first light blocking unit are set apart from each other by a distance different from a distance setting apart the second photoelectric conversion unit and the second light blocking unit.

    Abstract: A focus detection device includes: an imaging unit having a first pixel and a second pixel each of which receives light transmitted through an optical system and outputs signal used for focus detection; an input unit to which first information regarding a position on an image plane and an exit pupil distance of the optical system is input; a selection unit that selects a first focus detection based on the signal having been output from the first pixel or a second focus detection based on the signal having been output from the second pixel, based on the first information having been input to the input unit; and a focus detection unit that performs the first focus detection or the second focus detection based on a selection by the selection unit.

    CPC classification number: G02B7/34

    Abstract: Disclosed is an automatic focusing system. The illumination system is configured to generate two illumination beams directed toward the characteristic signal generation system. The characteristic signal generation system includes two transparent gratings with regular periods. The two illumination beams respectively pass through the two transparent gratings to form two transparent grating image beams which are directed to the TIR prism and the objective lens at different angles. The two transparent grating image beam after passing through the objective lens interfere on an object surface to form a moiré fringe image which is captured by the imaging system. The processor is configured to determine a defocus direction and a defocus amount according to a position of the moiré fringe image captured by the imaging system and further to determine an adjustment amount of a position of an objective lens according to the defocus direction and the defocus amount.

    Abstract: Apparatus and methods employing a PDAF optical system are disclosed herein. An example apparatus includes an image sensor comprising a plurality of pixels. The plurality of pixels include a set of pixels configurable to be imaging pixels or focus pixels. The image sensor is configured to generate image data of a scene based on received light at the plurality of pixels. The example apparatus also includes a processor coupled to the image sensor. The processor may be configured to receive first image data of a first frame of the scene, determine at least one region of interest or region of non-interest of the first frame, select, based on the determined at least one region of interest or region of non-interest, a subset of the set of pixels to be focus pixels, and cause the selected subset of the set of pixels to operate as focus pixels.
