A camera control section () fixes among parameters for photographing which are set in a camera (), another parameter than exposure time, and causes the camera () to photograph a photographing target area while changing the exposure time. An image acquisition section () acquires N (N&#x2265;3) images of the photographing target area acquired by photographing by the camera (). A model generation section () extracts for each pixel position, pixel values of a same pixel position from the N images, and generates a model indicating for each pixel position, a relationship between exposure times and pixel values, based on the extracted pixel values of the same pixel position and an exposure time at a time of photographing of each of the N images. A luminance value calculation section () calculates a luminance value for each pixel position, using the generated model and a luminance coefficient. A luminance distribution generation section () generates a luminance distribution of the photographing target area, using the luminance value of each pixel position.
