Abstract
A technique for sensing color involves detecting a portion of incident light that is not filtered by a color filter in addition to portions of the incident light that are filtered by color filters. The output related to the unfiltered light is used along with the outputs related to the filtered light to correct for voltage offsets that affect the amplification of the outputs. In an application, the output related to the unfiltered light is subtracted from the outputs related to the filtered light in a calculation of a linear transformation matrix.
