Abstract:
An image sensing apparatus having image sensing elements for converting an optical image of an object into electrical image signals and constructed so as to generate low resolution image signals on the basis of the electrical image signals in a first mode or to generate high resolution image signals in a second mode, selectively, comprising:detecting means for detecting levels of the electrical image signals; andcorrection means for correcting either exposure of said image sensing elements or levels of the electrical image signals or both on the basis of an average level of the electrical image signals whose levels are detected by said detecting means so that the average level of the electrical image signals approach a predetermined average value in the first mode, and for correcting either exposure of said image sensing elements or levels of the electrical image signals or both on the basis of a peak level of the electrical image signals so that the peak level of the electrical image signals approach a predetermined peak value in the second mode.
