Abstract
The present invention is directed to a method of calibrating a light source. In one embodiment, a standard image sensor is used to capture emitted light of a standard and a to-be-calibrated light source in order to obtain a standard and a nonstandard image, respectively. A standard and a nonstandard luminance response are generated according to the standard and the nonstandard image, respectively. The to-be-calibrated light source is adjusted until the nonstandard luminance response is about equal to the standard luminance response. In another embodiment, the standard image sensor is used to capture emitted light of the standard and the to-be-calibrated light source. According to sampled outputs of the standard image sensor, a standard and a nonstandard chrominance response are respectively generated, which are used to compensate an image sensor under test.
