Abstract: A VGA to analog video converter is useful e.g. for displaying video and/or graphics data from a computer onto a large screen television or television monitor. The RGB video signals output from the personal computer are first converted to digital form. The analog-to-digital converter which does this is clocked by a clock signal generated by a phase-locked loop using the horizontal synchronizing signal from the personal computer. The digital RGB signals are then converted to a YCbCR format. A flicker filter eliminates the flickering appearing on the TV monitor by operating on the luminance (Y) component. The YCbCr signals are encoded into NTSC or PAL Standard, and output in composite analog video or S-VHS format. A color subcarrier synthesizer generates the color subcarrier signal to generate an accurate subcarrier frequency for the video output signals. An analog-to-digital clock phase adjustment is used to ensure that the input RGB signals are sampled at the proper instant by the analog-to-digital converters.

Abstract: A video decoder transcodes video data from various input formats to a predetermined output format. Input data may be standard definition data or MPEG2 compressed data. Standard definition data are rearranged into block format to be compatible with the decoder's single display processor. The display processor selectively processes and conveys either MPEG2 format data or non-MPEG2 format data to a display device. A block based frame memory stores MPEG2 and non-MPEG2 pixel block data, as well as standard definition data in raster line format during processing.

Abstract: In a video signal reproducing apparatus, the changing time of a sub-video signal is adjusted, by a time-adjusting circuit, so as to be synchronized with the changing of a frame of a main video signal from the output of an interlace-scan-video-signal converter. And the sub-signal is added to the output of an interlace-scan converter by an adder. The output of the adder is converted into a progressive-scan video signal in synchronism with the boundary of frames of main video signal by the progressive-scan video signal converter. In the reproducing apparatus, even in the case that the sub-video signal is recorded without synchronism with the frames of the main video signal, an irregular frame is not generated even when the sub-video changes. And a single field of the sub-video does not leave or is not visible.

The top sub-pixels of the second multi-sample are the bottom sub-pixels of a multi-sample of the first line of the second field. Also, the bottom sub-pixels of the second multi-sample are the top sub-pixels of the second line of the second field. The second multi-sample is written into the frame buffer.

Display drivers receive the horizontally scaled re-interlaced fame and produce therefrom television display signals for forming images on a television, a high definition television of other type of television display.

Abstract: The invention provides an image processing apparatus and method as well as a providing medium by which deterioration of the vertical resolution is prevented and conspicuous appearance of line flickering is suppressed. In order to convert an interlaced video signal having 525 scanning lines into another progressive video signal having 525 scanning lines while maintaining the image size, in an odd-numbered field, a line after conversion is offset by 0.5 H (H is the distance between horizontal scanning lines of the inputted video signal). Consequently, pixel data of each line Oi are produced from pixel data of two lines Ii and Ii+1 before conversion. As a result, pixels of a line on the boundary between white pixels and black pixels have a gray color. In an odd-numbered field, no offset is given, and pixel data of each line I1 of the field before conversion are set as they are as pixel data of each line Oi of the field after conversion.

Abstract: Two images are analyzed to compute a set of motion vectors that describes motion between the first and second images. A motion vector is computed for each pixel in an image at a time between the first and second images. This set of motion vectors may be defined at any time between the first and second images, such as the midpoint. The motion vectors may be computed using any of several techniques. An example technique is based on the constant brightness constraint, also referred to as optical flow. Each vector is specified at a pixel center in an image defined at the time between the first and second images. The vectors may point to points in the first and second images that are not on pixel centers. The motion vectors are used to warp the first and second images to a point in time of an output image between the first and second images using a factor that represents the time between the first and second image at which the output image occurs.

Abstract: A matrix display panel has scan lines that are selected in consecutive order. An interlaced image signal is displayed by the use of one or more output enable signals that enable only every second selected scan line to be driven.

Consequently, no frame memory is needed for scanning conversion or frame-rate conversion.

Abstract: Signals of odd lines in progressive scanning image signals in a first frame are extracted and displayed along odd lines on a matrix-type display device such as a liquid crystal display panel. Further, signals of even lines in progressive scanning image signals in a second frame successive to the first frame are extracted and displayed along even lines on the display device. Thus, one image of a frame is displayed on the display device in two frame periods so that one of the first and second steps is performed after the other thereof is performed. Alternatively, one of the signals of odd lines are displayed along two successive odd and even lines, while one of the signals of even lines are displayed along two successive even and odd lines. The display methods can be applied to a display panel having a larger number of scanning lines than a number of signal lines.

Abstract: A CCD converts an optical image of an object formed on its image sensing surface into electrical charges, and sequentially outputs the electrical charges of all of the light receiving pixels in one scanning operation in non-interlaced form. The outputs from the CCD are converted to the digital image signals by an analog-digital converter. A camera signal processing unit processes the digital image signals, thereby generating two streams of signals; one is digital video signals SV1 which are standard digital video signals in interlaced form, and the other is signals SV2 which are not outputted as the digital video signals SV1 out of the digital image signals of all of the light receiving pixels. These two streams of signals, SV1 and SV2, are processed differently depending upon a mode selected by a switch.

Abstract: A frame/field converter circuit addition-processes image data constituting respective fields in a ratio corresponding to an image pickup mode or the like and outputs the resulting image data. As a result of this, it is possible to perform addition processing on image data constituting respective fields in an optimum ratio corresponding to an image pickup mode or the like and output the resulting image data. This makes it possible to improve the frequency characteristic and S/N ratio of the image and thereby enhance the quality of the displayed image. A contour compensation circuit performs contour compensation processing with respect to the frequency band of the image data in correspondence with the zoom magnification. As a result of this, it is possible to mitigate the level of the return noises generated in correspondence with the zoom magnification and thereby prevent the deterioration of the frequency characteristic and S/N ratio of the image to thereby enhance the quality of the image.
