Abstract
An image pick-up apparatus includes: an image sensing section which photoelectrically converts light from an object into an electrical output having a logarithmic function in relation to an amount of the light to produce image data regarding a light image of the object; an extracting section which extracts a particular portion having a specified luminance from the light image; a discriminating section which discriminates whether the particular portion has a light source; a data generating section which generates white balance adjustment data of the image data at a specified interval; and a changing section which changes the generation interval based on a result of the discriminating section. This apparatus can assure suitable and accurate color correction in accordance with a changed light source and for each of a variety of photographic scenes.
