PURPOSE:To output a photometric value suitable for a main object even if the luminance difference exists between the main object and a background and even if the weather changes, etc., by obtaining the photometric value from the luminance information of the area of a central part obtained before photographing and the luminance information of the area of a peripheral part obtained at the time of photographing after that. CONSTITUTION:A titled device provides a luminance information means for holding the luminance information obtained by photometry in the area of the central part of a light receiving means at the time of arranging the main object in the central part of a screen before photographing and a photometric value output indication means for making a computation means output the photometric value computed based on the luminance information obtained by photometry in the area of the peripheral part of the light receiving means at the time of photographing and the luminance information of the area of the central part held by a luminance information holding means to an arithmetic means. And the photometric value is obtained from the luminance information of the area of the central part obtained before photographing and the luminance information of the area of the peripheral part obtained at the time of photographing after that and when the luminance difference between the main object and the background is large, the photometric value suitable for the main object can be obtained even if the weather changes, etc.
