Problems solved by technology

Due to the rapid development of technology, the design of the module chip and the production process, assembly, burning and other production processes will lead to uneven chromaticity in the module image, specifically showing that the image edge is reddish, small areas are reddish, and slashes are biased. Abnormal phenomena such as redness, greenish edges, and greenish small areas seriously affect the high-quality requirements of modules mass-produced on the production line

Abstract

A block-based color cast detection system and its detection method, which reduces the influence of light sources, noise and other external environments, and uses automatic white balance technology to improve algorithm stability and detection rate, and adopts simple and practical adaptive image analysis The block method, as well as the area detection method based on statistical probability, realize accurate and efficient color cast detection.

Description

technical field [0001] The invention relates to a detection system and its method, in particular to a block-based color cast detection system and its method, which are used to detect whether there is a color cast phenomenon in the image of a camera module, and can effectively detect the color cast region of the image. Background technique [0002] The RGB color mode is a color standard in the industry. It obtains a variety of colors by changing the three color channels of red (R), green (G), and blue (B) and superimposing them with each other. Yes, RGB is the color that represents the three channels of red, green, and blue. This standard includes almost all the colors that human vision can perceive. It is one of the most widely used color systems at present. [0003] At present, users' demand for camera modules is getting higher and higher, which not only requires advanced technologies such as high pixels, large aperture, large field of view, optical image stabilization, and...
