Abstract
An electronic image sensing apparatus for photoeletrically converting an optical image in an image sensing unit, processing the resultant analog image sensing data, and recording, displaying, outputting, or externally outputting the processed image sensing data includes an analog semiconductor memory, a processor, and a luminance distribution adjustment unit. The analog semiconductor memory temporarily stores the image sensing data from the image sensing unit in the form of an analog value. The processor generates adjustment information for adjusting a luminance distribution of the entire image sensing data on the basis of luminance information of the image sensing data read out from the analog semiconductor memory. The luminance distribution adjustment unit adjusts the luminance distribution of the entire image sensing data from the analog semiconductor memory on the basis of the adjustment information generated by the processor.
