Abstract: PURPOSE:To improve the robust properties to the factor of fluctuation and to surely detect a desired frame by calculating the degree of assuredness of a fact that the candidate area of a subject is identical with the subject and using the evaluation value of the calculation. CONSTITUTION:A shape deciding part 9 performs the shape measurement processing to the image of a candidate area extracted by an area extracting part 8 and compares the shape of the candidate area with the shape features of a registered mobile subject to verify whether the extracted area is identical with the mobile subject or not. Then the part 9 calculates the degree of assuredness of the subject for each frame. A position deciding part 11 calculates the coordinate value within a screen for the area decided as a subject and then calculates a distance (difference) set from the subject stored in a position storing part 12. Then an evaluation value calculating part 13 applies the evaluation functions to several frames preceding and following a noted frame based on the difference between the degree of assuredness calculated by the part 9 and the subject position decided by the part 11. Then the evaluation is carried out in a certain frame range so that the frame including the subject is detected.
