A parallax detector detects a parallax between a left-eye image and a right-eye image of an input stereoscopic image signal. A vector detector detects an inter-frame motion vector in the stereoscopic image signal. An output controller determines whether or not to generate an interpolated frame based on the detected parallax and motion vector, and outputs a control signal indicating a result of the determination. An output image generator generates an interpolated frame having an interpolation phase using the motion vector when the control signal indicates that an interpolated frame is to be generated.
