摘要： Integrated processing of multimedia signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated system includes a main player that captures and processes signals digitally, a dummy display, and a dummy speaker. The dummy display may only have a display panel and a panel driver. The dummy speaker may only have a driving unit and no crossover logic. The main player may have a PC architecture and process all signals digitally for outputting signals tailored for the display device and the individual driving units of the dummy speaker. The integrated system may generate parameters for optimizing display of a video source. These parameters can be shared among users over a network connection.

摘要： A display apparatus, for instance a television receiver, comprises a cathode ray tube (3), a first circuit (1) for providing a high voltage (HV) to the cathode and a second circuit (2) receiving a gross signal (Y') and providing on at least an output at least a luminance signal (Y) controlling an electron stream of the cathode ray tube (3). To reduce stray emission, absence of gross signal (Y') is simulated when the apparatus is switched from on to off.

摘要： The projection display device stores, in a frame memory, a shot image of a test pattern for cases where the obstacle is not represented in the region of the projection; compares, at a comparison unit, a shot image of the test pattern for the case where the obstacle is represented in the region of the projection, with the stored shot image of the test pattern in order to detect an obstacle present in the region of the projection; generates, at an image-mask enlargement-processing unit, an image mask section having a region larger than the region of the detected obstacle; and effects, at a luminance control unit, a control to reduce the luminance in the image mask section.

摘要： An image processing system enabling luminance regulation depending on displayed images is provided by a projector, the projector including: a signal input section 110 which input an image signal; a signal output section 130 which outputs a corrected image signal; an image projecting section 190; a correction table storage section 140 which stores a correction table showing the relationship between a correction amount and a position in an image; an instruction input section 150 which inputs instruction information representing a correction instruction from a user; and a luminance regulating section 120 which corrects a luminance value of the input image signal to make a luminance value in a central portion of an image lower than the current luminance value of the center portion when uniformity improvement of luminance values in central and marginal portions of the image is desired, or corrects that to make a luminance value in a marginal portion of an image lower than the current luminance value of the marginal portion when emphasis of a central portion of the image is desired, based on the correction table and the instruction information.

摘要： In an image projection on a screen, an image projection apparatus improves the safety of entry into a proj ection region by the human body and does not bring about the increase of complexity of the configuration thereof owing to the improvement of the safety. A monitoring area is regulated on the outside of the projection area (3) of the screen (2). A detection wave such as infrared rays is emitted from a detection wave source (1c) of the image projection apparatus (1) . A reflection wave from the monitoring area is detected by reflection wave detection means (1d) such as a CCD sensor. Whether the human body or an obstacle enters the monitoring space, which is surrounded by a detection wave (4) between the main body unit of the image projection apparatus (1) and the screen (2), or not is detected. Once the entry is detected, the intensity of the radiation light traveling toward the projection area (3) is reduced or cut off according to the situation or the degree of the entry.

摘要： A method and apparatus for controlling the brightness of an image processing device to improve a brightness characteristic of an image signal, by reducing a pedestal voltage range and correspondingly expanding a brightness control voltage range in a highlight mode. The brightness control method includes the operations of determining whether a highlight mode is enabled; and if the highlight mode is enabled, reducing a pedestal voltage range by a first predetermined value and expanding a brightness control voltage range by a second predetermined value. The pedestal driving voltage and the brightness control voltage can be reciprocally controlled without modifications to a circuit having limited amplification, and the brightness can be improved without saturating an image in a highlight mode.

摘要： A video processing system is described for providing an image having more than one region on a display (DISPLAY). The system has a control means (1110; 110) which can determine, for each region (501, 502; 510, 520, 530), the type (e.g., graphics, text, computer programs, broadcast TV video, etc.) of the image material being displayed in the region (501, 502; 510, 520, 530). The system also has a video driver (1155; 135) coupled to the display for providing image signals having contrast and brightness characteristics. The control means (1155; 135) generates a control signal for causing said video driver means to adjust said contrast and brightness characteristics of said image signals according to the type of material being displayed in said region.
