    摘要： An image data coding apparatus adopting the method of this invention includes a divider section for dividing an image having gray levels into a plurality of blocks, each consisting of a plurality of pixels; a pre-processing section for detecting the density and the presence/absence of an edge in an image of each divided block; and a vector quantizing section for encoding an image of each block in accordance with the detected density and the presence/absence of the edge in the image of the block. The pre-processing section detects a standard deviation of density levels of the pixels included in each block. The vector quantizing section divides the density levels of the pixels included in each block into a plurality of level sections so as to obtain a code indicating the level section in which the density level of each pixel is included. In the vector quantizing section, the obtained code is again encoded by means of vector quantization.

    摘要翻译： 采用本发明的方法的图像数据编码装置包括：分割部分，用于将具有灰度级的图像分成多个块，每个块由多个像素组成; 用于检测每个分割块的图像中的边缘的密度和存在/不存在的预处理部分; 以及矢量量化部分，用于根据检测到的密度和块的图像中边缘的存在/不存在来对每个块的图像进行编码。 预处理部分检测每个块中包括的像素的浓度水平的标准偏差。 矢量量化部分将每个块中包括的像素的浓度级别分割成多个级别部分，以获得指示包括每个像素的浓度级别的级别部分的代码。 在矢量量化部分中，通过矢量量化再次对所获得的码进行编码。

    摘要： A display apparatus is configured to control a clock generator so that a phase of a clock can maximize an integrated evaluation value that is an integrated value of a differential absolute value between adjacent pixels in an image display unit over one frame of a plurality of digital video signals corresponding to a plurality of clocks having different phases generated by the clock generator when a value made by dividing a maximum value of the integrated evaluation value by a minimum value of the integrated evaluation value is larger than a threshold, and to control the clock generator so that the phase of the clock can correspond to an intermediate position in a phase range in which the position becomes constant relative to the phase of the clock when the value made by dividing the maximum value by the minimum value is equal to or smaller than the threshold.

    摘要： In order to produce a high-quality output of an image which is a mixture of images having different characteristics, there is provided an image processing apparatus having an image memory storing an entered color image and a feature detector, arranged for detecting a feature signal from the entered color image and storing the feature signal in the image memory. The feature signal represents a feature of the entered color image. An outputter is arranged for reading an image signal of the entered color image and the feature signal thereof out of the image memory, and outputting the image and feature signals as a recording signal. Processors are arranged for respectively processing one of a number of color components, which represent color image information, in accordance with the recording signal. The detection and storage in the image memory of feature signals and the readout of the image signal and associated feature signal from the image memory are performed in parallel.
