摘要： 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.

摘要： In an image displaying apparatus including a motion compensated rate converting (FRC) portion, deterioration of image quality is prevented in an image having a high-speed region and a low-speed region mixed. The FRC portion includes a motion vector detecting portion 11e and an interpolation frame generating portion 12b. The motion vector detecting portion 11e includes a first region detecting means 112e1 that detects a first region (high-speed region) including a motion amount equal to or greater than a first predetermined amount from an input image signal, a second region detecting means 112e2 that detects a second region (low-speed region) including a motion amount equal to or less than a second predetermined amount from the input image signal, and a third region detecting means 113e that detects a still region from an inter-frame difference of the input image signal. The interpolation frame generating portion 12b executes a motion compensated interpolation process using motion vectors for the still region in the first region (background) and executes a zero-vector interpolation process for the still region in the second region (foreground).

摘要： 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.

摘要： It is an object to suppress a disturbance or distortion of an insertion image in the vicinity of an effective image edge portion such as an edge portion of a screen or the like caused by a moving compensation type frame rate conversion (FRC). An image processing device is provided with a moving vector detection circuit (2) for detecting a moving vector of an input image signal, an effective image edge portion judging circuit (5) for judging if a moving vector detecting position is adjacent to the effective image edge portion, and a vector switching circuit (3) for switching a vector in accordance with the judging result. The vector switching circuit (3) fixes the vector to 0 vector in the case where the moving vector detecting position is adjacent to the effective image edge portion. In the case where the position is in other region, the vector switching circuit (3) outputs the moving vector detected by the moving vector detection circuit (2) to an insertion vector allocation circuit (4).

摘要： 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.
