摘要： A method for processing video data to produce a progressively scanned signal from an input of conventional interlaced video. The data is received at a processor (1), used to determine a motion signal (26) over time between field of the data. The motion signal is filtered to reduce errors caused by noise-corrupted video sources and then further filtered to spread out the determined motion signal. Edge information (30) is located and combined with the motion signal to produce an integrated progressive-scan signal (36) for display on a video display device, producing images with sharper edges and motion signals which have a lower susceptibility to noise.

摘要： A motion adaptive method for vertically scaling an image. The image data is analyzed to obtain a motion magnitude value for each pixel (31). The pixel data is then processed with two scaling processes (35, 36), performed in parallel. One scaling process is better suited for low motion images and the other is better suited for high motion images. The motion magnitude value is used to select between or combine (38) the pixel data outputs of the two scaling processes (35, 36).

摘要： A method of pulse width modulation using a spatial light modulator (40) with a finite transition time. The method uses m bits per sample to digitize the incoming data, but apportions the LSB times for pulse width modulation based upon m-1 bits. The current video frame displays all of the bits for each sample, except for the LSBs for each sample. The next video frame displays all of the bits for each sample, adding one more LSB for dividing up the frame time. The first frame could use either the additional LSB time and display no data, or it could use only that number of LSB times it needs. In the latter, the system will have to adjust to different partitions of the frame time for alternating frames. The system includes a spatial light modulator (40), a memory (42), a formatter (48), a sequence controller (44) and a toggle circuit (46), to perform this method.

摘要： A method and display system for reducing the visual impact of defects present in an image display. The display includes an array of pixels, each non-defective pixel being selectively operable in response to input data by addressing facilities between an "on" state, whereat light is directed onto a viewing surface, and an "off" state, whereat light is not directed onto the viewing surface. A defect is the result of a defective pixel which does not respond to the input data presented by the addressing facilities, typically by continuously remaining in its "on" or "off" state. Each defective pixel is immediately surrounded by a first ring of compensation pixels adjacent to the central defective pixel. The compensation pixels are immediately surrounded by a second ring of reference pixels spaced from the central defective pixel. The addressing circuit-determined value of at least one compensation pixel in the first ring surrounding the defective pixel is changed to a corrective value, in order to reduce the visual impact of the defect.

摘要： A line generator (31) for receiving fields of pixel data sampled from a video input signal and for generating additional lines of pixel data so that the display frames will have more lines than the fields. The line generator (31) has a motion detector (31a) that determines, on a pixel by pixel basis, whether some part of the current field is in motion. A motion signal from the motion detector (31a) is used to select between outputs of two or more pixel generators (31b, 31c). One of the pixel generators (31b) provides pixel values that are better suited for display when the image is not in motion. The other pixel generator (31c) provides pixel values that are better suited for display when the image is in motion.

摘要： A method of reducing artifacts in SLM-based display systems (10, 20), whose images are based on data displayed by bit-weight for pulse-width modulated intensity levels. The method can be used with a multiple spatial light modulators SLM system (20), which concurrently displays images of different colors, or with a single SLM system (10), which generates differently colored images sequentially during each frame period. For a multiple SLM system (20), the method is used with SLMs (14) that are memory-multiplexed, having "reset groups" that are loaded and displayed at different times. Corresponding rows of the SLM(s)s are associated with different reset groups.

摘要： A digital television system (10) is provided. System (10) may receive a video signal at composite video interface and separation circuit (16). The video signal is separated into separate video signals by composite video interface and separation circuit (16). The separate video signals are converted to digital video signals in analog to digital converter circuit (18). Line slicer (14) divides each line of digital video signal into a plurality of channels such that each channel may be processed in parallel by channel signal processors (22a) through (22d). Each channel signal processor (22a) through (22d) may provide two lines of output for each line of video input. The processed digital video signals may be formatted for displays (26a) through (26c) in formatters (24a) through (24c).

摘要： An SLM-based video receiver (10) receives a video input of some standardized format at a signal interface unit (11) and passes the input to a processor (12). The processor (12) performs analog-to-digital conversion if the pixel data is analog and also performs other enhancements to prepare the pixel data for loading into a video memory (14). The pixel data from the processor (12), representing a field of pixel data, is stored into the memory (14) for loading into rows of pixel elements of a spatial light modulator (16). The spatial light modulator (16) receives the pixel data in rows and each individual pixel element responds accordingly. The pixel elements of the spatial light modulator (16) emit light or reflect light from a source (18) and generate a video frame for display on a screen (20). By exploiting the addressing functions of the spatial light modulator (16), the SLM-based video receiver (10) displays a video frame using a field of pixel data.
