摘要： A block noise removal device classifies, into separate pixel groups, interpixel differential values by using a block size N (where N is an integer) of the decoded video signal or by using M which is an integer multiple of the block size N. The block noise removal device accumulates the interpixel differential values in the pixels disposed in the nth position (where n is 1 to N or 1 to M) in the respective pixel groups. This accumulation is performed for each of the first to Nth positions or the first to Mth positions in all the pixel groups. The results of the accumulation provide first to Nth block noise values or first to Mth block noise values. Then, the largest block noise value among the first to Nth block noise values or the first to Mth block noise values is found. A block boundary position signal is produced that represents, as a block boundary position, the pixel position in the pixel group that corresponds with the largest block noise value. The larger of two block noise values of the adjacent pixels on both sides of the pixel having the largest block noise value is taken as the phase error block noise value. A phase error signal is then generated on the basis of the ratio between the phase error block noise value and the largest block noise value. Block noise removal processing is effected on the basis of a phase correction pixel sample value. The phase correction pixel sample value is obtained by performing phase correction processing based on the phase error signal on the decoded video signal.

摘要： A block noise removal device calculates a block boundary correction value. This correction value indicates a correction amount for a pixel sample value immediately before a block boundary position and a correction amount for a pixel sample value immediately after the block boundary position for each block boundary position in a pixel sample value sequence. Each pixel sample value represents a level of each pixel in a video signal. The block noise removal device obtains the block boundary correction value based on at least two consecutive pixel sample values immediately before the block boundary position and at least two consecutive pixel sample values immediately after the block boundary position. The block noise removal device then generates a block noise correction signal representing a correction amount for the pixel sample values corresponding to respective pixels in the pixel block is generated by performing interpolation computations based on the block boundary correction value found for each two adjacent block boundary positions. The block noise removal device adds the block noise correction signal to the video signal to produce a noise-removed video signal from which block noise has been removed.

摘要： A signal processing device outputs a (n+m)-bit return signal. A random number addition device generates an m-bit random number, and adds this number to the return signal. A round-down device rounds down the lower m bits of the return signal with the random number added. While such a process is repeated for the same pixels in a video image by several frames, the frequency of a carry caused by the random number addition corresponds to a numerical value shown by the lower m bits rounded down. As a result, the number of bits of the return signal is changed to n bits by the round-down process. However, information about the lower m bits rounded down is divided in a time direction and added to a video output signal.

摘要： A data recording apparatus records data onto a recording medium having a flash memory in which data can be written in block units using a part of a recording region as an alternative block for a defect block in which normal data writing cannot be performed. The data recording apparatus causes a user to select one of plural recording modes including a first recording mode and a second recording mode in which an amount of data to be processed is larger than that of the first recording mode, then obtains data in the selected recording mode and stores the data onto the recording medium. If an alternative block remaining amount obtained from the recording medium is equal to or less than a threshold value, the data recording apparatus allows recording in the first recording mode and inhibits recording in the second recording mode.

摘要： Prepared is brightness frequency data that indicates the number of pixels, having the same brightnesses in a brightness distribution for each of the fields represented by an input image signal. Based on the brightness frequency data, the number of subfields for emission at each brightness in a brightness region is adjusted for each of at least two brightness regions. As a result, the greater the frequency indicating the total number of pixels at each of the same brightnesses in a brightness region, the larger the number of subfields allocated to that brightness region. Therefore, satisfactory grayscale representation suitable to human visual characteristics is achieved.

摘要： A method of grayscale-driving a display panel in accordance with pixel data derived from a video signal. The display panel includes a plurality of display lines, with a plurality of pixel cells serving as pixels being arranged on each display line. A display period of a single field of the video signal is divided into a plurality of subfields. The method includes dividing one subfield into M lower subfields. M is an integer greater than one. M groups of display lines are prepared by sequentially taking every M display lines from the display lines. First to Mth address steps are performed in the M lower subfields respectively and sequentially. Each address step sets the pixel cells belonging to the display lines of the display line group concerned, to a drive mode determined by the pixel data. A first light emission step is performed to cause the pixel cells whose drive mode is a lit mode, to emit light directly before or after the address step concerned. Another subfield is divided into N lower subfields. N is smaller than M. N groups of L continuos address steps are prepared from the first to Mth address steps. L is an integer greater than one. The N groups of L continuous address steps are performed in the N lower subfields respectively and sequentially. A second light emission step is performed to cause the pixel cells whose drive mode is the lit mode, to emit light directly before or after the address step group concerned.

摘要： A video signal processing apparatus which performs a frame-rate conversion of a progressive line-scan video signal based on a film source of M film frames per second (wherein M is a natural number) into a video signal in which a same film frame is repeated N times for each 1/M second, and mixes, frame by frame, a video signal of a preceding frame and a video signal of a following frame of the converted progressive line-scan video signal. Thus, the display quality of telecine-converted images can be improved.
