摘要： Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a video image, that when displayed, includes a picture portion, a non-picture portion, and a subtitle which is superimposed on at least a subset of the non-picture portion, where the non-picture portion has an initial brightness value. Then, the system scales the brightness of pixels corresponding to a remainder of the non-picture portion of the video image to have a new brightness value that is greater than the initial brightness value to reduce user-perceived changes in the video image associated with backlighting of a display that displays the video image, where the remainder of the non-picture portion excludes the subset of the non-picture portion.

摘要： A video processing chip capable of adjusting aspect ratio and a method of displaying an image thereby are provided. The video processing chip outputs an adjusted image signal according to a video signal to an LCD panel to display an image. The video processing chip includes a video processor, a ratio detector, a timing controller, and a multiplexer. The video processor generates an image signal according to the video signal. The ratio detector detects the aspect ratio of the video signal, and outputs a ratio control signal according to a ratio setting value. The timing controller outputs a vertical blanking signal, a horizontal blanking signal, and a blanking data in responding to the ratio control signal. The multiplexer selects the blanking data signal or the image signal as the adjusted image signal to be outputted, so that the displayed image has the aspect ratio corresponding to the ratio setting value.

摘要： Embodiments of a system that includes one or more integrated circuits are described. During operation, the system receives a sequence of video images, where a given video image in the sequence, when displayed, includes a picture portion and the non-picture portion, and where the picture portion has a histogram of brightness values. Then, the system determines the intensity setting of the light source on an image-by-image basis based on the histogram, where the light source is configured to illuminate a display that is configured to display the sequence of video images. Next, the system selectively filters changes in the intensity setting of the light source, where the selective filtering is based on a magnitude of a given change in the intensity setting from a previous video image to a current video image.

摘要： The present invention relates to an improved interpolation based on motion compensation. In order to avoid interpolation artefacts in proximity to the image borders, in particular in letterbox type images, each motion compensated image data is subjected to a position validation in order to determine whether or not the motion compensated image data can be used for interpolation purposes. By comparing the position of the motion compensated image data in the referenced images with predefined borderlines, impermissible image data positions can be detected and interpolation based on such image data prevented.

摘要： A method and apparatus for changing the number of scan lines in a frame of video data to produce an image represented by the video data that corresponds to a desired aspect ratio. The apparatus includes a pair of finite impulse response filters for processing the decoded chrominance and luminance pixel values stored in memory. The filters permit a plurality of scan lines of chrominance and luminance data to be read and filtered on a continuous basis with any scan line of data being read only once. Thus, the filters provide a very efficient method of providing a frame of a number of output scan lines of chrominance and luminance pixel values that are different from the number of scan lines of chrominance and luminance pixel values in a frame of video data stored in memory.

摘要： An aspect ratio discrimination apparatus and an image display apparatus which prevent a malfunction in discrimination of a first video signal for exhibition of a normal image and a second video signal for exhibition of a horizontally elongated image. An upper-lower portion average brightness calculation section receives an input video signal to form an image and calculates an average brightness of upper and lower portions (black band portions) of the image. An upper-lower portion brightness difference calculation section calculates differences between the average brightness and brightness levels of the black portions of the image. A high brightness difference rate detection section discriminates whether or not the rate of the area of portions in the black portions in which the brightness differences are higher than a predetermined level is higher than a predetermined value. When the rate of the area is higher than the predetermined value, it is discriminated that the video signal inputted to the aspect ratio discrimination apparatus or the image display apparatus has the aspect ratio of 4:3.

摘要： An adaptation of an aspect ratio of a picture signal is effected by providing (1) a second derivative (D2) of an expansion factor (EF) in response to at least one constant value (C1, C2), by providing (3-13) a first derivative (D1) of the expansion factor (EF) in response to the second derivative (D2), by providing (14-21) the expansion factor (EF) in response to the first derivative (D1), and by expanding the picture signal in dependence upon the expansion factor (EF) to adapt the aspect ratio of the picture signal, whereby use of an expansion factor (EF) less than one results in a compression of said picture signal.

摘要： A video signal compression apparatus extracts a specific value written in a read only memory at every system clock pulse. The specific value can be varied at every clock pulse. Therefore, for example, only the center part of a picture can be horizontally compressed. A FIFO memory may be used. It is possible to select a mode with a fixed compression ratio or a mode in which a compression ratio varies at every clock pulse. Further, the fixed compression ratio can be set from the outside. Display position of the picture can also be changed.
