摘要： It is an object to prevent the image quality deterioration of a moving image likely to include a plurality of the same consecutive images such as a movie video image or a CG video image due to the motion-compensated frame rate conversion (FRC) processing. An image displaying device is provided with an FRC portion (10) for converting the number of frames in an input image signal by interpolating an image signal to which a motion compensation processing has been given between the frames in the input image signal, a controlling portion (14) for controlling each portion according to an image tone mode selected by a user.; The FRC portion (10) includes a motion vector detecting portion (11e) for detecting a motion vector between the frames of the input image signal, an interpolating vector evaluating portion (11f) for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion (12d) for generating an interpolating frame from the interpolating vector. In the case that the image tone mode selected by the user is a predetermined image tone mode, the controlling portion (14) set the motion vector detected by the motion vector detecting portion (11e) to zero-vector to make the motion compensation processing of the FRC portion (10) ineffective.

摘要： The crosstalk of a display apparatus can be efficiently eliminated to realize a precise, high-quality display. A liquid crystal display apparatus includes, as a crosstalk elimination circuit, an adjacent picture element acquisition circuit (1) that acquires display signals of picture elements adjacent to a self picture element, and two-dimensional LUTs (2) that use the display signals of the adjacent picture elements, acquired by the adjacent picture element acquisition circuit (1), to correct display signals of the self picture element so as to correct RGB display signals. The picture element display signals as corrected by the correction values output from the LUTs (2) are output to a source driver (4) via a timing controlling unit (TC) (3). In the crosstalk elimination circuit, the display signals of a picture element to be corrected and those of picture elements adjacent to the picture element that influence the picture element are used to acquire a correction value, thereby correcting the display signals of the correction target picture element.
