ABSTRACT:
At least one exemplary embodiment is directed to an image pickup apparatus configured to switch between a color and a black & white photographing modes, which includes an image pickup optical system, an image pickup element that receives a light through the image pickup optical system and opto-electronically converts the received light, a first luminance detecting unit that detects a luminance of a photographed object based on a signal from the image pickup element, a second luminance detecting unit that detects the luminance of the photographed object by receiving a light without intervention of the image pickup optical system, and a filter converting mechanism for interposing any one of a infrared cutoff filter and an optical element in an optical path of the image pickup optical system.
