Abstract:
1. An image sensing apparatus comprising: a color image sensor configured to perform a first exposure operation for processing incident light by using a first photoelectric conversion property and a second exposure operation for processing the incident light by using a second photoelectric conversion property differing from the first photoelectric conversion property, said color image sensor having capability to separately output first and second output signals obtained by the first and second exposure operations, respectively; a correction coefficient calculator for calculating correction coefficients used for correcting white balance of the first and second output signals; a processor for selecting output signals to be used as signals for constituting an image from among the first and second output signals for individual color components thereof based on a comparison between the level of each of the first and second output signals and one of threshold values; and a threshold setter for setting the threshold values for the individual color components according to the correction coefficients.
