Patent ID: 8446526

Claim:
An image displaying device, comprising: a rate converter that interpolates an image signal subjected to a motion compensation process between frames or between fields of an input image signal to convert the number of frames or the number of fields of the input image signal for output to a display panel, the rate converter generating an interpolation image not subjected to the motion compensation process for a predetermined edge region of a display screen adjacent to edges including the edges on the left, right, top and bottom of the display screen for an image signal to be displayed on the display panel including edges of an effective image displayed on the display panel, the rate converter generating an interpolation image subjected to the motion compensation process for regions other than the predetermined region, the rate converter including: a motion vector detecting portion that detects as vector information a motion of an image between consecutive frames or fields contained in the input image signal; an interpolation vector allocating portion that allocates an interpolation vector between the frames or between the fields, based on the detected motion vector information; an interpolation image generating portion that generates an interpolation image signal from the input image signal, using the allocated interpolation vector; and an image interpolating portion that interpolates the generated interpolation image signal between the frames or between the fields, wherein the image displaying device invalidates the motion compensation process in either or both of horizontal and vertical directions for the predetermined region by fixing at 0 either or both of horizontal and vertical components of a motion vector in the predetermined region detected by the motion vector detecting portion, and the predetermined region is a region whose width from edges of the effective image is equal to or less than the maximum motion vector length detectable by the motion vector detecting portion.
