Problems solved by technology

However, since pixels that are not subject to pixel mixing exist within the effective area of ​​the solid-state imaging device, it is unfortunate that high sensitivity cannot be achieved.
In addition, as a result of uneven arrangement of the reduced number of pixels for each color obtained by mixing, there is a problem of unevenness in the image.

Abstract

To solve problems of a conventional moving picture photographing using a high pixel density color solid-state imaging element that reflected noise intruded to a low frequency region of a high frequency video signal due to resampling is unavoidable and the effective sensitivity is remarkably deteriorated through aborted pixel signals although interleaved pixel reading represented by pixel interleaving in the vertical direction is generally employed. Pixel areas of the high pixel density color solid-state imaging element are divided into areas in units of pixel mixture, and all pixels in the same color are respectively mixed in each of the area divisions (16 to 19) to increase the pixel utilizing rate to 100%, and the spatial LPF effect of area pixel mixing remarkably suppresses the intrusion of reflected noise to the low frequency region of the high frequency video signal.

Description

technical field [0001] The present invention relates to color solid-state imaging devices for digital still cameras, digital video cameras and the like. Background technique [0002] Conventionally, solid-state imaging devices that convert received optical signals into electrical signals and output them as video signals are well known, and video cameras such as digital still cameras that display video signals obtained from this solid-state imaging device as still images are also known to every household. In recent years, video cameras using such a solid-state imaging device have higher requirements for image quality and performance, and improvement in image quality has been rapidly developed. [0003] For example, as long as it is a solid-state imaging device with 5 million pixels, the number of pixels in the vertical direction is about 1920 pixels, and the number of pixels in the horizontal direction is about 2560 pixels. The number of pixels is about 16 times higher than ...
