FIELD: information technology. ^ SUBSTANCE: disclosed is a liquid crystal display device comprising: means (14) of converting frame frequency via interpolation of an image which is corrected based on an interframe motion vector between frames of input video signals. During interpolation of signals which are represented by two or three successive identical images generated in television projector equipment for use in the next interpolated image, motion vectors are recalculated based on motion vectors (Va) used in generating the first interpolated image, thereby identifying motion vectors having high accuracy and fewer errors; a unit (10) for determining a repeated image, and uses an interval during which identical images successively appear without the need for identifying vectors for further increase in accuracy of motion vectors identified between the image and the other immediately preceding image. ^ EFFECT: high accuracy of identified vectors and generating interpolated images of higher quality, even if the device processes such data as three to two pull-down or two to two pull-down, having high probability of deterioration of accuracy of identified vectors due to a wide interval of movement. ^ 3 cl, 6 dwg |
