Abstract:
    This invention provides an image sensing apparatus and method, which can independently calculate and display the histograms of the entire range and selected range of image data sensed by an image sensing element. In an image sensing apparatus of this invention, a microcomputer (16) calculates the histogram of the entire area of image data sensed by an image sensing element (6), and that of image data of an area selected by an operation member (18) which is used to select a photometry mode, and identifiably displays these calculation results on an EVF (12) via circuits from a video signal processing circuit (10) to an EVF driving circuit.
