  • Patent number: 8446526
    Abstract: 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).

  • Patent number: 8395700
    Abstract: 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.

  • Patent number: 7901103
    Abstract: A backlight unit includes a fluorescent lamp to illuminate a liquid crystal panel, a reflection unit for causing the light from the fluorescent lamp to exit toward a certain direction, and a diffusion unit for diffusing the light from the fluorescent lamp and reflection unit, and reflectance or transmittance in the horizontal and vertical directions is controlled by applying a dot pattern that gradually increases densities from the central portion toward the peripheral portion to the reflection unit or diffusion unit, or by applying a dot pattern that gradually increases densities from the central portion toward the both ends in the longitudinal direction on the surface of the fluorescent tube of the fluorescent lamp. By doing this, brightness gradient is formed in the horizontal and vertical directions so that the brightness in the central portion of the liquid crystal panel is relatively higher than the brightness of the peripheral portion thereof.

  • Publication number: 20100091185
    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.
