摘要： An image signal processing apparatus inputs a video signal, delays it by one field using a field memory, multiplies the delayed signal by a value K (K less than 1), adds the output from the multiplication to the input signal and supplies the sum to the field memory. The level of the signal read out from the field memory is compared with a predetermined value, and based on the result of that comparison, the video signal being input is substantially inhibited from being supplied to the adding means. The signal obtained by multiplying the immediately-preceding field signal by k, and the present-field signal, are cyclically added, so that the amplitude can be gradually increased. The comparison inhibits addition of a new field signal when the level of that stored in the field memory has reached a predetermined level.
摘要翻译：图像信号处理装置输入视频信号，使用场存储器将其延迟一个场，将延迟的信号乘以值K（K小于1），将来自乘法的输出与输入信号相加，并将该和值提供给场记忆。将从场存储器读出的信号的电平与预定值进行比较，并且基于该比较的结果，基本上禁止输入的视频信号被提供给加法装置。通过将前一场信号乘以k而获得的信号和当前场信号被循环地相加，使得振幅可以逐渐增加。当存储在现场存储器中的电平达到预定水平时，该比较禁止添加新的场信号。

摘要： An image processing apparatus in which the amount of data bits for each of plural block units is controlled to be the same for all block units, so as to facilitate location of each block unit in coded image data without necessarily decoding the entire image. Pixel image data which is formable into plural block units is input for each block unit, and the input image data is orthogonally transformed. The orthogonally-transformed image data is quantized, and variable-length coding is performed on the quantized image data so as to generate variable-length code. The amount of variable length code in each block unit is controlled to be no more than a predetermined amount of data bits, with the predetermined amount being the same for each block unit.

摘要： An image processing apparatus has a memory device for storing pixel image data, including both halftone image data such as data of image of a photograph having a gradation, and line image text data such as data, containing characters. The storage is conducted on the basis of blocks each having a predetermined number of pixels. The mean information quantity of the halftone image data per pixel stored in the memory means is not greater than the information quantity of the line image data per pixel stored in the memory means. The halftone image data is compressed on the basis of blocks. Therefore, both the halftone image data and line image data can be stored in a small memory by using common addresses, without causing any degradation of the image quality.

摘要： An image recording control apparatus analyzes color image data outputted by a host computer and determines whether image data of each recording color component of a printing device is present. If there is a color component for which image data is not present, an image recording process based upon this color component is skipped. As a result, a meaningless recording process is no longer performed even if the side transmitting the recording data does not apply special processing to the recording data about to be transmitted.
