Patent ID: 7221778

Claim:
An image processing apparatus for processing image data which is formed of a predetermined number of pixel data obtained by an image-capturing device including a predetermined number of pixels, the pixels having a time integrating function, said image processing apparatus comprising: a first movement detector configured to detect an amount of movement between frames of a foreground object of a designated frame of the image data based on the designated frame and a frame preceding or subsequent to the designated frame; a ratio detector configured to detect a mixture ratio indicating a ratio of mixture of a foreground object component constituting the foreground object and a background object component constituting a background object in a mixed area in the designated frame, in which the foreground object component and the background object component are mixed; a second movement detetor configured to detect, in accordance with the mixture ratio, an amount of movement of the foreground object within an exposure time in which the pixel data constituting the image data is obtained; and an exposure-time detector configured to detect a ratio of a time interval of the frames to the exposure time based on the amount of movement between the frames and the amount of movement within the exposure time of the foreground object.
