Abstract: 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 and an animation video 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 genre determining portion (14) for determining whether the input image signal is a predetermined genre, and a controlling portion (15). 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 (102) for generating an interpolating frame from the interpolating vector. In the case that the input image signal is relating to a movie or animation, the control portion (15) 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.

Abstract: An image processing device and method, and an image display device and method which realizes a high-definition displayed video by reducing motion blur caused by a holding-type display system and reducing motion blurs of the displayed video caused by the time integration effect of an image sensor while suppressing deterioration of an image. The image display device includes a motion vector detection section (101) which detects a motion vector in each predetermined region between the frames of an inputted image signal, and an edge emphasis part (2) which emphasizes the high-frequency component of the inputted image signal and an interpolated image signal generated by an FRC part (100) according to the motion amount of the inputted image signal detected by the motion vector detection section (101). This compensates the high-frequency component attenuated by the time integration effect of the image sensor to reduce the apparent motion blurs to improve the sharpness of the displayed image. By making the degree of edge emphasis of the interpolated image signal smaller than that of the inputted image signal, the sharpness of the displayed image is improved without making the image deterioration of the interpolated image signal distinct.

Abstract: In an image displaying device provided with a frame rate conversion (FRC) portion, the image quality deterioration in a moving image likely to include a plurality of the same consecutive images due to a FRC processing is prevented. The FRC portion (100) of the image displaying device includes a motion vector detecting portion (101) that detects motion vector information from an input image signal, an interpolation frame generating portion (106) that generates interpolation frames based on the motion vector information obtained by the motion vector detecting portion (101) and a same image detecting portion (105) that detects a case where the same images continue in the input image signal. In the case where the image of the (n−1)-th frame in the input image signal is substantially the same as the image of the n-th frame, interpolation image generating processing with the motion compensation processing made ineffective is performed between n-th frame and (n+1)-th frame to prevent that the interpolation image including a lot of errors is output.

Abstract: In an image display device having a frame rate converting (FRC) portion, it is possible to prevent image degradation of a combined image display portion such as an OSD and PinP attributed to the FRC process. The image display device includes: an FRC portion 10 for converting the number of frames of an input image signal by interpolating an image signal subjected to a motion compensation process between the frames of the input image signal; an OSD processing portion 14 for superposing an OSD signal on the input image signal, and a controlling portion 15. The FRC portion 10 has a motion vector detecting portion 11e for detecting a motion vector between the frames of the input image signal, an interpolation vector evaluating portion 11f for allocating interpolation vector between frames based on the motion vector information, and an interpolation frame generating portion 12d for generating an interpolation frame from the interpolation vector. When the OSD signal is superposed on the input image signal, the controlling portion 15 disables the motion compensation process of the FRC portion 10 by making the motion vector detected by the motion vector detecting portion 11e 0 vector.

The video image signal processing portion (16) adequately controls the video signal processing of the portion of the second video signal superimposed on the first video signal by using the video combining information, thereby prevents image degradation of and around the portion of the second video signal caused by the video signal processing, and generates a video with higher quality.
