AI Technical Summary
The color reproduction capability of a multispectral camera module is affected by the optical lens and filter, resulting in poor color calibration accuracy. The three-channel camera module cannot accurately reproduce the color information of the multispectral camera module, resulting in large image color deviation.
Design a filter whose transmittance curve is similar to the spectral response curve of the human eye. By limiting the spectral response range and angular offset, improve the color reproduction capability and color calibration accuracy of the camera module.
It improves the color reproduction capability and image color fidelity of the multispectral camera module, reduces color difference between the center and edge of the image, enhances the color correction accuracy of the three-channel camera module, and improves the user experience.
