摘要： A video with a display definition most suitable for the type of the video content to be displayed can be displayed. A liquid crystal display apparatus controls the luminance of the backlight light source according to the APL of the video signal measured by an APL measuring portion (16). The range of the video signal the APL of which is measured can be determined by, e.g., the luminance level of the video signal or by the genre information included in the inputted video signal or the OSD display information used when the liquid crystal apparatus (1) performs OSD display. The drawing shows the state that the upper and lower non-video areas are removed and an effective video area is determined. With this, the additional information displayed when the video signal is of a specific genre and the OSD-displayed additional information can be excluded, and the luminance of the backlight light source can be controlled to realize a display definition most suitable for the video signal.

摘要： Deterioration of the image quality of a moving image which is deteriorated due to a motion-compensated frame rate conversion (FRC) processing is prevented. An image display device comprises an FRC portion (10) for converting the number of frames of an input image signal by interpolating an image signal to which the motion compensation processing is performed between frames of the input image signal and a controlling portion (15) for controlling the operation of the FRC portion (10) after determining whether or not the degree of deterioration of the input image signal is equal to or higher than a predetermined value. The FRC portion (10) comprises a motion vector detecting portion (11e) for detecting a motion vector between 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. If the degree of deterioration of the input image signal is equal to or higher than a predetermined value, the controlling portion (15) makes the motion compensation of the FRC portion (10) ineffective by setting the motion vector detected by the motion vector detecting portion (11e) to a zero vector.

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 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.

摘要： An image-processing apparatus, as well as an image-processing method, is provided with a first inspection circuit which, with respect to density values of pixels within a specific area consisting of a target pixel and pixels in a vicinity thereof in image data for each color component, calculates an average density value, the sum of density differences, that is, the sum of absolute values of differences between the target pixel and the peripheral pixels, and the number the peripheral pixels having the same density value as the target pixel, so that a judgement is made as to whether the target pixel is a maximum value or a minimum value, and also calculates a run-length and the degree of busy from the pixel forming the maximum value or the minimum value. Moreover, based on the run-length and the degree of busy, the second inspection circuit extracts a pixel weight switching signal for each of the color components, and detects the periodicity of meshes of image data by counting pixels not less than the standard value or not more than the standard value based on the pixel weight switching signal within a predetermined counting area. With this arrangement, it becomes possible to carry out the discrimination between character areas and mesh areas as well as the discrimination between black character areas and white character ares with high precision.

摘要： A display device uses a plurality of monitors to constitute a single image, achieves high contrast and, suppresses variations in luminance among the monitors. Each monitor is provided with an image analysis portion that finds a first feature quantity in a video display region corresponding to a region of an LED backlight, and a gradation control portion that determines a first luminance level for the corresponding LEDs region and calculates a luminance stretch quantity for stretching the first luminance levels uniformly. A microcomputer selects a minimum luminance stretch quantity from among the monitors and outputs the selected minimum luminance stretch quantity to the monitors. The gradation control portion for each monitor stretches the first luminance levels uniformly to determine a second luminance level on the basis of the minimum luminance stretch quantity acquired from the microcomputer.
