Abstract: An image adapter transforms an input image into an output image by successively processing tiles and by changing numbers of columns and of rows of image points. The image adapter includes queue memories connected in series so as to receive values associated with the points of a tile of the input image. A module for calculating a weighted average possesses inputs connected respectively to an output of one of the memories. The module produces values sampled in a direction parallel to the columns and corresponding to the values associated with points of the input image. A sampling rate converter, connected to the output of the module, produces values associated with the points of the output image according to a sampling rate determined for a direction parallel to the rows.

Abstract: A dynamic region, such as subtitles, is detected in a stream of digital video, and displayed along with a static region also in the stream, such as a video region, so that nearly all of the total vertical display area of a monitor displaying the dynamic and static regions is filled. For example, when the dynamic region is detected, the vertical size of the static region is adjusted to allow the vertical display of the dynamic and static region on the monitor simultaneously, without extending beyond or reducing to less than the total vertical display size of the monitor. Also, when the dynamic region is not detected, the vertical height of the static region is adjusted to fill the total vertical display size. Moreover, iterative increase and decrease in the vertical sizes of the regions may allow for a more pleasant viewer experience.

Abstract: When television screen setting is not set and thus a television screen setting completion flag is not set, and a terminals-connection judgment pin takes a low level, an i/p selection screen is initially displayed on a progressive display device. However, the i/p selection screen is not displayed on an interlaced display device. When processing performed for the i/p selection screen is completed, or when the terminals-connection judgment pin takes a high level, indicating that the video input D-terminal of the display device is not connected to the video output D-terminal, an aspect ratio setting screen is displayed. After aspect ratio setting is completed, the television screen setting completion flag is set. This eliminates the need to perform the television screen setting again.

Abstract: An adaptive compensation system for aspect ratio conversion. Video information, intended for her first aspect ratio display, e.g. the standard NTSC aspect ratio, is processed to determine additional information that can enable that video to be displayed and fill a wider aspect ratio screen. The processing can be a calculation which calculates, for example, texture, color and/or brightness of the edge portions, and automatically calculates video information to match the texture, brightness or color. The processing can be a database lookup, which automatically looks up likely portions from a database. The processing can also be an adaptive determination of what vertical portions of the image can be stretched without affecting the viewability, and then an adaptive stretching of different portions by different amounts.

Abstract: Designed for use with widescreen TVs or high-end TVs with a mode for accommodating anamorphic programs, an EPG client is equipped with an electronic program guide (EPG) and a letterbox-to-anamorphic converter. The EPG client evaluates EPG data to determine whether programs are in the letterbox format.

The converted anamorphic program is output to the television, where it is horizontally expanded to fit the screen.

Abstract: A method and an apparatus for calculating source image coordinates. In an embodiment, a variation rate of the source image coordinate with respect to a converted image coordinate is calculated by a recursive computation, and variation rates are accumulated to obtain the source image coordinate. Because the converted image coordinate sequentially increases one-by-one, the variation rate may be obtained by using adding operations of previously obtained source image coordinate, rather than multiplying operations with the all of the converted image coordinates. Therefore, the source image coordinates may simply and effectively be calculated.

Abstract: A system and process for creating an apparently higher resolution image on a display exhibiting a lower resolution is presented. The basic idea is to make multiple decimated versions of an image at different offsets in a smooth path (all of which will contain different bits of detail), and then animate through the resulting decimated images (i.e., show them in rapid succession). The viewer sees what looks like a higher-resolution image moving in a smooth path. The viewer sees this since the human eye is capable of integrating details over the continuous motion. Thus, images such as text enjoy an enhanced legibility.

Abstract: A microprocessor in a digital broadcast receiver outputs image data displaying a menu in a sub-screen when instructed by a user to display the menu: if received broadcast signals are those of an HD broadcast, and if the image format of a television, to which data are output, is 1080i or higher, and further if the screen size of the television, to which data are output, is 37 inch or larger; namely if characters in the menu are unlikely to be corrupted even when the television displays the menu in the sub-screen, and if there is no possibility that characters in the menu become too small to be identifiable. Thereby, it becomes possible for the television to display the menu in the sub-screen if the user can identify characters in the menu even when the television displays the menu in the sub-screen. Accordingly, the user can input setting of menu items while watching broadcast images.

Abstract: Described is an adaptive scheduler associated with a desktop window manager that dynamically controls the rate at which graphics frames are composed. Values corresponding to performance when composing a frame are measured, and the frame composition rate is adjusted as necessary based on the values. The measured data is sampled to provide smooth adjustments. The sampled data is evaluated as to whether the current frame rate is too slow, too fast, or acceptable. If too slow, the frame rate may increased relative to the refresh rate, while if too fast, the frame rate is decreased relative to the refresh rate. In one implementation, the frame rate is too fast if a count of missed frames achieves a missed threshold value, or if a count of late frames achieves a late threshold value. The frame rate is too slow if a count of early frames exceeds an early threshold value.

Abstract: When a video display system displays an image having an aspect ratio that differs from the aspect ratio of the system's display monitor, the image spans only an “active” portion of the available display area on the monitor. The display system sets the luminance and/or chrominance of pixels in the inactive areas of the monitor to match the average luminance and/or chrominance of a selected group of pixels forming the image in the active area. This helps prevent ghosting by aging the phosphors or other material forming the pixels in the active and inactive areas at the same rate.
