Abstract: An electronic device includes at least one processor or circuit configured to function as a setting unit, an acquisition unit and a processing unit. The setting unit sets an object region in an image acquired from an imaging unit. The acquisition unit acquires a distance map including distance information corresponding to a pixel included in the object region. The processing unit determines object distance information indicating a distance to an object included in the object region, based on the distance information corresponding to the pixel included in the object region.

Abstract: An image data processing apparatus includes: an image data acquisition unit for acquiring low resolution image data and high resolution image data; and a confidence data determination unit for determining confidence data which indicates a level of confidence in a pixel value in the high resolution image data. The determination unit determines the level of confidence of a target pixel in the high resolution image data based on a comparison between a first and a second evaluation value. The first evaluation value is determined based on pixel values of neighboring pixels in a pixel position in the low resolution image data corresponding to a pixel position of the target pixel in the high resolution image data. The second evaluation value is determined based on the pixel values of the neighboring pixels, using a method that is different from the first evaluation value.

Abstract: An imaging device according to the present invention includes multiple pixels arranged in a row direction and a column direction, which are orthogonal to each other. The multiple pixels include distance measurement pixels each including multiple photo-electric converters arranged so as to be adjacent to each other in the row direction. When M and N denote integers not smaller than one, the pixels are arranged at positions shifted in the row direction for every M-number rows by an amount corresponding to a half of the pixel, color filters are arranged in the row direction in an array of N-number columns per cycle, and the color filters are arranged in the column direction in an array of 2MN-number rows per cycle.
