ABSTRACT:
A method for enabling an output device to emulate colors of a target camera includes the following steps: (a) utilizing the target camera to shoot a color chart to obtain a first plurality of output values respectively corresponding to a plurality of color patches of the color chart, (b) utilizing the output device to shoot the color chart to obtain a second plurality of output values respectively corresponding to the plurality of color patches of the color chart, (c) comparing the first plurality of output values with the second plurality of output values to deduce a color transform matrix, and (d) applying the color transform matrix in an image processing pipeline of the output device to enable the output device to emulate colors of the target camera.
