Introduce the antidote of the camera lens module aberration that the embodiment of the present invention provides with reference to figure 1, comprise the steps:
Step 100: the ambient color temperature value obtaining the current residing environment of camera lens module.
For same camera lens module, because the ambient color temperature value of varying environment is different, thus make same camera lens module can produce different aberration under various circumstances, need to adopt different rectification standards to correct, the accuracy of guarantee correction result.After the environment residing for camera lens module is determined, easily by measuring the ambient color temperature value obtaining current residing environment.
Step 200: find out the color temperature parameters of camera lens module under ambient color temperature value from the colour temperature-color temperature parameters corresponding relation curve of camera lens module.
Wherein, colour temperature-color temperature parameters embodies the parameter of the color representation of camera lens module under certain colour temperature, such as, can be the parameter of proportionate relationship between this colour temperature hypograph R, G, B component (red component, green component, blue component).Color temperature parameters can be following arbitrary or combination: R/B parameter, R/G parameter, G/B parameter, R/B parameter refers to the ratio of R component and B component, and R/G parameter refers to the ratio of R component and G component, and G/B parameter refers to the ratio of G component and B component.
Step 300: find out the color temperature parameters of standard specimen camera lens module under ambient color temperature value from the colour temperature-color temperature parameters corresponding relation curve of standard specimen camera lens module.
