Abstract
An image processing apparatus with interframe interpolation capabilities for reproducing a sequence of video frames by performing a frame interpolation between two given video frame images to compensate for dropped frames. The image processing system comprises an outline detection unit to detect the outline of each moving object contained in a frame image and an affine parameter calculation unit to calculate first affine parameters based on the geometrical relationship between one outline image at a first point in time and another outline image at a second point in time. Based on the first affine parameters, an affine parameter interpolation unit performs a linear interpolation to produce second affine parameters corresponding to a third point in time between the first and second points in time. An interpolated image generation unit then applies an affine transformation to the object images at the first or second point in time, using the second affine parameters supplied from the affine parameter interpolation unit, thereby generating another frame image of each moving object at the third point in time.
