Embodiment Construction

[0091] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0092] [Overall structure of the digital camera of the first embodiment]

[0093] figure 1 It is a block diagram of a digital camera (imaging device) 10 including the first embodiment of the color imaging device of the present invention. The CPU 11 of the digital camera 10 sequentially executes various programs and data read from a memory not shown based on control signals from the operation unit 12 including a shutter button and various operation buttons, and collectively controls each unit of the digital camera 10 .

[0094] A zoom lens 14 , a focus lens 15 , a mechanical shutter 16 , and the like are incorporated into a lens unit (photographing optical system) 13 . The zoom lens 14 and the focus lens 15 are respectively driven by the zoom mechanism 17 and the focus mechanism 18 to move back and forth along the optical axis O1.

Abstract

A color imaging element comprising: first group pixels; second group pixels at positions shifted half; and color filters which are arrayed on each of the first and second group pixels, wherein the color filter array includes a basic array pattern in which first filters corresponding to a first color and second filters corresponding to a second color whose contribution rates for acquiring a brightness signal are lower than a contribution rate of the first color are arrayed, and is formed by repeatedly arranging the basic array pattern, one or more of the first filters are arranged in horizontal, vertical, diagonal upper right and diagonal lower right directions, one or more of the second filters are arranged in the basic array pattern, and a ratio of a number of pixels of the first color is greater than a ratio of a number of pixels of each color of the second color.

Description

technical field [0001] The present invention relates to a color imaging device and an imaging device, and more particularly to a color imaging device and an imaging device capable of reducing the occurrence of color moiré fringes and achieving high resolution. Background technique [0002] A digital camera (imaging device) equipped with a color imaging element such as a CCD color imaging element or a CMOS color imaging element and that acquires a digital image is widespread. In recent years, digital cameras have been able to generate various image data depending on the type of color imaging device. [0003] For example, the digital cameras described in Patent Documents 1 to 3 include: a first group of RGB pixels in which all pixels of a color imaging element are arranged in a predetermined pattern; A group of RGB pixels are respectively arranged adjacent to a second group of pixels. Specifically, the RGB pixels of the second group are arranged at intervals of 1 / 2 pixels re...
