Patent number: 6498816Abstract: A video processing circuit includes a processor that receives encoded images each having respective first and second regions and that receives a motion vector of the first region of a first one of the images. If the motion vector points to the second region of an image, the processor re-encodes at least a portion of the first region of the first image such that the first region of the first image has no motion vector that points to the second region of an image.Type: GrantFiled: September 3, 1999Date of Patent: December 24, 2002Assignee: Equator Technologies, Inc.Inventors: Venkat V.

Patent number: 6362835Abstract: A method and system for adjusting the brightness and contrast of a digital pulse-width modulated display without scaling the input image data. Brightness is adjusted by changing the duty cycle of a displayed pixel either by altering the bit display durations, or by turning the pixel on during blanking periods 36. The contrast ratio may be altered by changing the display duration of at least one of the MSBs differently than the display duration of at least one of the LSBs. Contrast may be increased by extending the MSB display periods 50 and shortening the LSB display periods 52. Contrast may be decreased by shortening the MSB display periods 56 and extending the LSB display periods 58. The color tint of the displayed image may be altered by individually changing the brightness of the constituent colors.Type: GrantFiled: November 23, 1993Date of Patent: March 26, 2002Assignee: Texas Instruments IncorporatedInventors: Paul M. Urbanus, Robert J. Gove

Patent number: 6300924Abstract: 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.Type: GrantFiled: November 21, 1995Date of Patent: October 9, 2001Assignee: Texas Instruments IncorporatedInventors: Vishal Markandey, Stephen W.

Patent number: 6232936Abstract: A method and device for increasing the effective horizontal resolution of a display device. One embodiment forms a cardinal array of digital micromirror elements by staggering alternate rows in an array. According to a second embodiment, an ordinal pixel array 57, is converted to a cardinal pixel array, by grouping SLM elements 59, 61, 63, and 65 into a pixel block 58. All of the elements in a pixel block are controlled in unison such that the pixel block acts like a single pixel. Rows of pixel blocks 67 and 69 are offset to provide the effect of a cardinal array of pixels without the decrease in efficiency sometimes associated with cardinal pixel arrays.Type: GrantFiled: March 31, 1995Date of Patent: May 15, 2001Assignee: Texas Instruments IncorporatedInventors: Robert J. Gove, Jeffrey B. Sampsell

Patent number: 6116768Abstract: A data processing apparatus includes a three input arithmetic logic unit (230) that generates a combination of the three inputs that is selected by a function signal. Data registers (200) store the three data inputs and the arithmetic logic unit output. The second input signal comes from a controllable barrel rotator (235). The rotate amount is a default rotate amount stored in a special data register, a predetermined set of bits of data recalled from a data register or zero. A one's constant source (236) is connected to the barrel rotator (235) to supply a multibit digital signal of "1". This permits generating a second input signal of the form 2.sup.N, with N being the rotate amount. The output of the barrel rotator (235) may be stored independently of the arithmetic logic unit (230) result. In the preferred embodiment of this invention, the three input arithmetic logic unit (230) is embodied in a data processor circuits as a part of a multiprocessor integrated circuit (100) used in image processing.Type: GrantFiled: November 30, 1993Date of Patent: September 12, 2000Assignee: Texas Instruments IncorporatedInventors: Karl M.

Patent number: 5999227Abstract: A system for handling special television video features digitally. The system receives incoming broadcast video into a switch (106). The switch allows the viewer to select a main channel and at least one auxiliary channel for viewing as a special feature, if the viewer does not want to view only the main channel for that particular special feature. The main video channel data is processed by a scan converter (216) to convert it from interlaced to progressive scan. A logic device (212) handles the auxiliary channel data to format it into the selected special feature and inputs that data to the scan converter (216) such that the special feature appears in the proper place relative to the main channel image.Type: GrantFiled: June 13, 1997Date of Patent: December 7, 1999Assignee: Texas Instruments IncorporatedInventors: Donald B.
