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： 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).

The video image receiving device (11) includes a receiving portion (12) for receiving the multiplexed data, a multiplexed data separating processing portion (13) for separating the multiplexed data into the video data and the video image decoding processing portion (14) and a video image composite information decoding processing portion (15) for decoding the video data and the video combining information respectively, and a video image signal processing portion (16) for subjecting the decoded video signal to a predetermined video signal processing. 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.

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： The quality of moving picture image with a large moving amount is prevented from deterioration due to moving compensation type frame rate conversion (FRC) processing. The image display device is comprised of an FRC unit (10) that interpolates an image signal subjected to moving compensation processing between frames so as to convert the number of frames of the input image signal, a moving amount judging unit (14) that judges whether a moving amount of the input image signal between the frames is larger than a predetermined value or not, and a control unit (15). The FRC unit (10) is provided with a moving vector detecting unit (11e) that detects a moving vector between the frames of the input image signal, an interpolation vector evaluating unit (11f) that allocates an interpolation vector between the frames on the basis of the moving vector information and an interpolation frame generating unit (12d) that generates an interpolation frame from the interpolation vector. In the case where the moving amount between the frames of the input image signal is larger than the predetermined value, the control unit (15) sets the moving vector detected by the moving vector detecting unit (11e) to be zero-vector, and it invalidates the moving compensation processing of the FRC unit (10).
