Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] In order to solve the problem in the prior art that when there are multiple color cast ribbons in the detection area, it is impossible to accurately detect the color cast ribbons in the picture, such as figure 1 As shown, the present invention provides a method for detecting a color cast ribbon, the method comprising:

[0027] Step S01: Set a standard area and calculate standard R / G / B values. The standard area is an area centered on the center of the s...

Abstract

The invention discloses a color cast color tape detection method. The method is that a detection area in which the ratio of a short shaft to a long shaft in the center is less than a preset ratio is provided; an image is detected at a plurality of times; whether the image is qualified can be determined; therefore, the problems that a plurality of color cast color tapes of different types are in the same detection area, and therefore, the difference between the related R / G / B ratio calculation result of the detecting result to the related standard R / G / B ratio cannot be observed, and as a result, that no color cast occurs is determined according to the value result, can be effectively avoided; the tape shaped color cast stripes can be accurately detected, and the color cast problem can be accurately determined.

Description

technical field [0001] The present invention relates to the technical field of camera modules, and more specifically, to a method for detecting color cast ribbons. Background technique [0002] With the development of science and technology, camera modules, as a video input device, are widely used in computers, cameras and mobile phones. The camera module plays a vital role in the quality of the shooting picture. A common picture quality problem is the phenomenon of color banding in the picture. The phenomenon of color banding in the picture usually manifests as reddish or The bluish band-shaped area can generally be directly observed on the image after ISP technology (converting and processing the data captured by the camera to make the converted image suitable for human eyes). However, what is observed in the process of detecting the color cast is a RAW image, that is, a picture that has not been processed by ISP. Within the specified exposure range, it is difficult to ju...
