Abstract
A video image pickup apparatus () includes an image sensor (), a knee processor () for performing a compression in a high-luminance characteristic interval of a picture signal based on an output signal of the image sensor, a block luminance calculator () for dividing a frame of image based on the output signal of the solid-state image pickup device into a set of blocks, calculating a set of luminance indices of respective blocks, an extreme extractor () for extracting a block having a highest luminance index, together with the luminance index, a display information generator () for generating a set of pieces of image information for exposure guide display including an image representing a region of the extracted block and an image representing the luminance index, an image superposer () for superposing the set of pieces of image information for exposure guide display on a frame of image based on the compressed picture signal to generate a frame of superposed image, and a view finder () for displaying the frame of superposed image.
