Abstract:
An image taking apparatus comprising:a taking optical system for imaging a subject light; a distance measurement optical system having an optical path different from an optical path of the taking optical system, and not interlocking with a change of a focal length of the taking optical system; a pair of image sensor arrays for receiving subject light imaged by the distance measurement optical system; a plurality of brightness monitors being placed close to one of the image sensor arrays, each independently for measuring a brightness of a subject in a predetermined area and for outputting a signal corresponding to the brightness; a selector for selecting a predetermined brightness monitor from among the brightness monitors based on a image taking condition; and a controller for controlling integration by the image sensor arrays based on the signal from the brightness monitor selected by the selector, wherein one of the brightness monitors has a measurement area being large compared to an other brightness monitor, and covers a measurement area of the other brightness monitor.
