Abstract
An endoscope photometric apparatus includes a photometric apparatus for detecting the brightness of an image based on an image signal from an endoscope imaging apparatus. An extracting apparatus extracts, from the image signal from the imaging apparatus, a bright part in which the brightness level from the peripheral of the image is above a predetermined value and the spatial size of the bright part is below a predetermined value. A limiting device limits the input image signal into the photometric apparatus of the part, corresponding to the bright part, in the image signal by using the output of the extracting apparatus in order to reduce the influence of the bright part on the brightness of the entire image.
