Method and Apparatus for Controlling a Camera Module to Compensate for the Color Spectrum of a White LED |
摘要 |
A method and an apparatus enabling use of a light source emitting a spectrum of light not following characteristics of a blackbody source of light with a camera module programmed for use with light sources following characteristics of blackbody sources of light, wherein a white-balance patch is transmitted to the camera module to cause the camera module to accept color coordinates representing a point on a chromaticity chart that partly defines a region of color coordinates on the chromaticity chart into which color coordinates of the light source fall and to which color coordinates of a reference white color derived by a white-balance routine of the camera module are constrained.
