Color image collection device based on gray level sensor and color image sensor

Abstract

The invention relates to the field of image sensors, and provides a color image collection device based on a gray level sensor and a color image sensor to achieve the aims of enabling the gray level sensor and the color image sensor to collect a gray level image of a frame and a color image of the same frame respectively, and thus synthesizing a truer color image by correcting untrue luminance information in the color image through more accurate luminance information of collected gray level image. According to the technical scheme, the color image collection device based on the gray level sensor and the color image sensor is composed of the gray level sensor, the color image sensor, an adder and a color image generator, wherein the adder is used for conducting weighting addition on the luminance information provided by the gray level sensor and the luminance information collected by the color image sensor, and luminance information obtained through the adder and chrominance information obtained through the color image sensor are converted to be in a required chrominance space through the color image generator so that the new color image can be generated. The color image collection device is mainly applied to design and manufacturing of the image sensors.

Description

technical field [0001] The present invention relates to the field of image sensors, especially in complex environments, the key technology of CCD and CMOS image sensor imaging, which is used to realize the fusion of grayscale and color image sensors to generate new images. Specifically, it involves the technology based on grayscale and color A color image acquisition device with two color sensors. Background technique [0002] Common CCD and CMOS image sensors are divided into two types: grayscale and color. The two sensors have their own advantages in imaging technology. The grayscale image sensor only collects luminance information and has no chromaticity information, so the collected luminance information is more real and accurate than the color sensor; the image information collected by the color sensor It contains chromaticity information that grayscale sensors do not have. [0003] With the complexity of the application environment of imaging systems and the higher r...

Problems solved by technology

The imaging system of 4 image sensors has a strong theoretical basis, but its practicability is not strong. The clock registration technology of multiple image sensors is the bottleneck that is difficult to break through in the simultaneous acquisition of multi-sensor data. If the clock registration cannot be accurately realized, For video information, multiple image sensors do not collect the same frame of data, and the image information loses its meaning. At the same time, the amount of image data collected by 4 image sensors is too large compared with a single sensor and 2 sensors. Both image processing and transmission cause troubles and are not suitable for real-time requirements
