Color image capturing element and image capturing device

Abstract

The present invention provides a color imaging element and an imaging device capable of improving the AF accuracy of phase difference detection pixels. The imaging element (14) has: a color filter (30), and a basic array pattern obtained by arranging the first array pattern and the second array pattern in a point-symmetrical manner is repeatedly arranged, and in the above-mentioned first array pattern, the first filter The chips are arranged on the four corners and central pixels of a square arrangement of 3×3 pixels, the second filter is arranged on the central row in the horizontal direction of the square arrangement, and the third filter is arranged on the vertical direction of the square arrangement On the central row, the configuration of the first filter in the second arrangement pattern is the same as that of the first arrangement pattern, and the configuration of the second filter is swapped with the configuration of the third filter; and phase difference detection pixels are arranged at least at positions corresponding to the first optical filters on the upper end side and the lower end side in the basic array pattern.

Description

technical field [0001] The present invention relates to a color imaging element, an imaging device, and an imaging program, and more particularly to a color imaging element including pixels for phase difference detection, an imaging device, and an imaging program. Background technique [0002] In solid-state imaging devices mounted on imaging devices such as digital cameras, in order to improve AF (autofocus) performance, some of the pixels formed on the light-receiving surface of the solid-state imaging device are used as pixels for phase difference detection. ( For example, refer to Patent Documents 1 to 7). [0003] A pixel for phase difference detection is constituted by a pair of adjacent two pixels on which filters of the same color are mounted, as described in the following patent documents 1 to 7, for example, and the openings of the light-shielding film are respectively compared with those provided in ordinary pixels. Small shade opening. Moreover, the light-shiel...

Problems solved by technology

[0012] In this AF operation, the more pixels for phase difference detection, the higher the accuracy. However, when taking a normal subject image, the opening of the light-shielding film of the pixels for phase difference detection is narrow and the sensitivity is low, so it cannot be compared with ordinary pixels. It is impossible to increase the number of pixels for phase difference detection excessively
