Abstract:
1. An apparatus for processing an image of an image signal projected through a digital camera lens, the apparatus comprising: an image sensor module configured to transform an optical signal projected through the digital camera lens into an electric signal, to generate and output an image signal; a light receiving module configured to receive light from a light source; a light source characteristic detector configured to detect a frequency of the light received by the light receiving module; and an auto color adjustment controller configured to identify a kind of light source by analyzing a frequency characteristic of the light source, and control a white balance gain of the image signal based on the kind of the light source, wherein the light receiving module comprises one or more circuits configured to determine the frequency of the light signal, wherein the one or more circuits comprise one of a processor configured to transform the light signal from a time domain to a frequency domain and a log transformer configured to transform the light signal into a log scale.
