  • Patent number: 5757432
    Abstract: A computer system which manipulates audio and video signals. A multimedia input device which generates an audio and/or video signal is coupled to a processor. The processor is also coupled to a storage device upon which a decompression routine is stored, the decompression routine including a transposition routine. The transposition routine manipulates data elements associated with the audio or video signal in transposing an array of n rows of a plurality of data elements. The transposition routine causes the processor to interleave data elements from a first row with data elements from a second row to generate a first result. Data elements from a third row are interleaved with data elements from a fourth row to generate a second result. Then, data elements from the first result are interleaved with data elements from the second result to generate a third result.

  • Patent number: 5754243
    Abstract: A read control circuit reads image data, which are stored in a decoding image memory, at a read speed m/n times a display speed. These image data are written to line memories by a write control circuit. A read-address control circuit reads the image data from the line memories at a display speed, and line data for a letter-box image are generated by multipliers and an adder. Specifically, the line data of m lines which are read from the decoding image memory are transformed to n lines so that a letter-box display is made possible. Thus, letter-box transformation processing is performed with less memory capacity without the use of a field memory.

  • Patent number: 5751343
    Abstract: A film image reproduction signal output apparatus is provided which picks up an image on a developed film by a CCD, and produces an image reproduction signal by an image pickup circuit so that the image is displayed on a monitor. The present output apparatus detects whether the film contained in a cartridge loaded in the apparatus is a negative film or a positive film. If the negative film is detected, the image pickup circuit produces the image reproduction signal by reversing an image signal received from the CCD, for display on the monitor.

  • Patent number: 5751341
    Abstract: A medical video endoscope system for allowing high-resolution three-dimensional images to be viewed has a stereoscopic endoscope for converting optical images of an object to left and right video image signals. An electronic processor module controls the stereoscopic endoscope and processes the left and right video image signals into time-multiplexed signals representative of high-resolution three-dimensional images having stereoscopic depth. The time-multiplexed signals are provided to a monitor which displays high-resolution video images based on the signals. A viewing device is provided which allows a viewer to see high-resolution three-dimensional video images having stereoscopic depth on the monitor. A rigid sheath assembly with an angled distal tip can be placed over a barrel of the endoscope and rotated with respect thereto in order to change the viewing direction of the stereoscopic endoscope.

  • Patent number: 5751361
    Abstract: An apparatus for use in a video signal decoding system for concealing errors in a video signal first detects a lost block in the video signal, the lost block having errors, and then provides pixel values of neighboring blocks for the lost block in the video signal based on information for the lost block. Subsequently, The apparatus computes edge gradients of neighboring pixels included in a predetermined range of pixels surrounding the lost block based on the pixel values of the neighboring blocks and determines a pixel interpolation direction based on the edge gradients of neighboring pixels. A spatially interpolated block is produced based on the pixel values of the neighboring blocks and the pixel interpolation direction and it is provided as a substitution block for compensating the lost block.

  • Patent number: 5751357
    Abstract: A run length coding (RLC) is implemented in a coder/decoder unit (CD) in a forward path (VP) and a run length decoding (RLD) is implemented at the beginning of reconstruction in a reconstruction path for an internal reconstruction of the video data stream. As a result an added outlay seems to occur as compared to known methods. However, an interleaving of tasks that were successively implemented in previous methods is thereby enabled. A substantial reduction of the overall outlay compared to known procedures is achieved by the interleaving of the scan method (SV), quantizing (Q) and run length coding (RLC), run length decoding (RLD), inverse quantizing (IQ) and the inverse scan method (ISV).

  • Patent number: 5751340
    Abstract: A method and apparatus for improving an image received from a endoscope having a flexible fiber optic bundle that produces an interstitial grid overlay due to the dead space between each fiber pixel. The interstitial grid pattern in the image, is substantially eliminated by processing the image through a linear digital filter to attenuate the first-order spatial frequency components that contribute most to the interstitial pattern. The filter employs relatively small convolution kernels that are optimized for specific fiber spacing. The image is then processed through the linear digital filter by convolving the respective pixels in the image by the derived coefficients. The image is improved and the grid pattern may also be reduced by a dilation process which involves processing the image through a dilation algorithm to "grow" the bright center of each fiber pixel in the image so that the effect of the grid pattern is reduced.

  • Patent number: 5748243
    Abstract: A method for encoding motion picture, a method for decoding motion picture, a motion picture recording medium, and a motion picture encoding apparatus of the present invention can suppress the decrease in information of the fine pattern of an image while mosquito noise is reduced even in a signal band where an SN ratio is low. When a motion picture signal is encoded by using a specified prediction picture signal, a specified operation is applied to the encoded signal, the signal obtained by the calculation is quantized, and the quantized signal is variable-length encoded, a signal band in which the SN ratio of the picture signal is lowered is quantized and emphasized based on a non-linear characteristic. Then, at the decoding side, a decoded signal is inversely quantized and demodulated based on a non-linear characteristic having a characteristic opposite to the encoding side.

  • Patent number: 5745166
    Abstract: A video security system (10) capable of monitoring and recording fixed and moving targets and recording management information into a video signal such that the text can be removed from the video image produced by the video signal at playback of the recorded video signal. The VSS (10) allows a camera (70b) to switch (toggle) between two or more view positions of interest and to set the view positions into memory by pressing a single switch. The cameras (70b) are controlled to move rapidly, but accurately, between the positions within controlled parameters of speed and acceleration--including a period of substantially zero acceleration between changes in the rate of acceleration.
