Abstract: An image processing device includes an inward state detection unit that detects, on the basis of an inward image acquired by photographing of a user side, a state of outside light in the inward image as an inward outside light state, and an outward state detection unit that detects, on the basis of an outward image acquired by photographing of an opposite side of the user side, a state of outside light in the outward image as an outward outside light state. Also included is a control unit that performs brightness adjustment processing related to brightness of the inward image according to a detection result of the inward outside light state and a detection result of the outward outside light state, and a recognition processing unit that performs gaze detection of the user on the basis of the inward image acquired by performance of the brightness adjustment processing.

Abstract: [Object] It is desired to provide a technology capable of appropriately controlling brightness of images by using a simpler structure. [Solving Means] Provided is an information processing device including: a determination unit that determines a range of brightness on a basis of a plurality of pieces of imaging data captured by a plurality of image capturing units; and an exposure control unit that controls exposure values of the plurality of image capturing units on a basis of the range of brightness.

Abstract: The present technology relates to an image processing device, method, and program in which an influence of outside light can be reduced. An image processing device includes: an inward state detection unit that detects, on the basis of an inward image acquired by photographing of a user side, a state of outside light in the inward image as an inward outside light state; an outward state detection unit that detects, on the basis of an outward image acquired by photographing of an opposite side of the user side, a state of outside light in the outward image as an outward outside light state; a control unit that performs brightness adjustment processing related to brightness of the inward image according to a detection result of the inward outside light state and a detection result of the outward outside light state; and a recognition processing unit that performs gaze detection of the user on the basis of the inward image acquired by performance of the brightness adjustment processing.

Abstract: An edge is detected by inputting a video luminance signal and based on a luminance signal difference. The detected edge is composed by the number in accordance with the number of pixels included in a block and counted by a plurality of counters corresponding to a horizontal position of an image. Values of respective counters are evaluated to identify a block boundary position. By performing filtering processing on the pixel signal at the identified block boundary position, a block distortion is reduced.
