Light source correction method and system thereof

Abstract

The invention discloses a light source correction method and a system thereof. The light source correction method comprises the following steps of firstly, through testing a camera shooting module group under a standard light source, acquiring a standard white balance calculation parameter of the tested camera shooting module group under the condition that an input brightness value of the standard light source is a first preset value; then, taking the standard white balance calculation parameter as a correction standard of a light source of a platform to be tested, using the same tested camera shooting module group to test under the light source of the platform to be tested, and taking a current input brightness value as a correction input brightness value when a difference value of a currently acquired testing white balance calculation parameter and the standard white balance calculation parameter is less than a preset threshold value so that when the input brightness value of the light source of the platform to be tested is a correction input brightness value, an irradiation environment which has similar brightness with the standard light source whose the input brightness value is the first preset value is acquired, and a purpose of correcting the light source of the platform to be tested is realized.

Description

technical field [0001] The present application relates to the technical field of camera module exposure correction, and more specifically, relates to a light source correction method and system. Background technique [0002] With the continuous development of electronic equipment, the integrated camera or camera function has become one of the necessary functions of various electronic equipment. [0003] In the calibration process of the camera module, it is necessary to perform exposure correction on the camera module under the standard light source of the exposure correction (AE calibration) platform, so as to obtain the white balance calculation parameters obtained by the camera module under the standard light source of the exposure correction platform, The white balance calculation parameter is an important parameter for the white balance calculation of the camera module, and also an important parameter that determines whether the camera module can well reflect the color ...

AI Technical Summary

Problems solved by technology

[0004] However, when the use status of the standard light source of the exposure correction platform or its own state changes (such as light source attenuation or temperature change, etc.), it may cause the actual brightness value of the light under the same input brightness value of the exposure correction platform. changes, resulting in the camera module not getting an accurate white balance calculation parameter after exposure correction, which in turn affects the imaging quality of the camera module
