Color image capturing element, image capturing device and image capturing program

Abstract

The purpose of the present invention is to improve the accuracy of phase difference AF control. An image capturing element (14) is provided with: a color filter (30) in which a basic arrangement pattern having a first arrangement pattern and a second arrangement pattern arranged to be symmetrical about a point is repeated, wherein the first arrangement pattern comprises first filters arranged on pixels in 2*2 arrangement located at the upper-left portion and a pixel located at the lower-right in a 3*3 pixel square arrangement, second filters arranged on the center and lower end lines in the vertical direction of the square arrangement, and third filters arranged on the center and right lines in the horizontal direction of the square arrangement, and wherein the second arrangement pattern comprises the first filters having the same arrangement as in the first arrangement pattern, and the second filters and the third filters having the arrangements interchanged with each other compared to the arrangements in the first arrangement pattern; and phase difference detection pixels arranged at positions corresponding to two pixels in the 2*2 pixel arrangement of at least one first arrangement pattern or second arrangement pattern, among all first arrangement patterns and the second arrangement patterns constituting the basic arrangement 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, an imaging device, and an imaging program including pixels for phase difference detection. Background technique [0002] In order to improve the AF (autofocus) performance of solid-state imaging devices mounted in imaging devices such as digital cameras, there is a technology that uses some of the pixels formed on the light-receiving surface of the solid-state imaging device as phase difference detection pixels ( For example, refer to Patent Documents 1 to 7). [0003] The phase difference detection pixels are, for example, as described in Patent Documents 1 to 7 below. They are composed of a pair of adjacent two pixels equipped with filters of the same color, and are provided with smaller apertures than the light-shielding film provided in ordinary pixels. The shading film opening. Furthermore, the light-shi...

Problems solved by technology

[0015] In this AF operation, the more pixels for phase difference detection, the higher the accuracy. However, there is a problem that when an ordinary subject image is actually captured, the opening of the light-shielding film of the pixels for phase difference detection is narrow and the sensitivity is low. Cannot be processed in the same way as normal pixels, so the number of pixels for phase difference detection cannot be excessively increased
