    摘要: A video contrast enhancer enhances luminance contrast by dividing each video frame or field into blocks, calculating a mean luminance level for each block, selecting mapping functions on the basis of these mean luminance levels over a series of frames or fields, and mapping the video luminance levels according to the selected mapping functions. Color-saturation contrast is enhanced by modifying the amplitude of the modulated chrominance signal by the histogram equalization method, preferably by making a single linear modification in each period of the chrominance signal, so that color phase is not affected. For video signals with non-picture bands, these enhancements are preferably restricted to the picture area. If a black offset is present, it is preferably removed.

    摘要: A thermal transfer recording sheet is produced by placing, on one side of a sheet-like heat-resistant substrate successively along the surface, one or more thermal transfer recording layers containing a recording material which contains a binder material and a coloring material and whose viscosity is lowered and controlled by temperature-raise recording control, so that transferability to recording medium is imparted, and a thermal transfer coating layer containing a hot-melt material which is miscible (compatible) with at least a part of said binder material.The thermal transfer recording using said thermal transfer recording sheet is characterized by first subjecting the thermal transfer coating layer to temperature-raise recording control, forming a film of the hot-melt material on the surface of the recording material at least on a portion to which the recording material is transferred, and conducting thereon thermal transfer recording as usual. By this thermal transfer recording, the unevenness of transfer can be reduced and the recording sensibility can be improved.

    摘要: In a double superheterodyne tuner for receiving TV channel signals, a frequency in a range defined between 2520 and 2700 MHz is selected as the first intermediate frequency, while the first intermediate frequency is obtained by subtracting a desired channel frequency from a first local oscillator frequency. The tuner comprises first and second mixing circuits respectively used for effecting frequency conversion, where each of these mixing circuits has parallel coupled lines so that each mixing circuit operates as a balance-to-unbalance transformer. The second mixing circuit further comprises a short-circuit line placed between the parallel coupled lines. The tuner also comprises a band pass filter having a band width less than 5 MHz, which selectively transmits the first intermediate frequency signal from the first mixing circuit.
