摘要： An image signal processing apparatus detects a motion vector between two temporally successive frames, and includes a detection device, a calculation device, and an arithmetic device. The detection device is configured to detect the motion vector in pixel blocks between the two frames, and output an evaluation value, which represents the degree of correspondence between the two frames in the pixel blocks provided in the two frames, and which is calculated in the process of detecting the motion vector. The calculation device is configured to calculate an activity value, which represents the degree of variation in pixel value in the frame, on the basis of the direction of the detected motion vector. The arithmetic device is configured to perform an arithmetic operation to obtain an accuracy value, which represents the degree of reliability of the detected motion vector, on the basis of the evaluation value and the activity value.
