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： In an image processing method, image information described by a page descriptor language is developed by the page descriptor language into a form not pasted with to-be-pasted image information, without reading out, for image development, the to-be-pasted image information from a unit for storing the to-be-pasted image information. The image information in the form not pasted with the to-be-pasted image information and the to-be-pasted image information are separately transmitted to a printer. The image information in the form not pasted with the to-be-pasted image information is compressed by reversible coding. The to-be-pasted information is compressed by irreversible coding.

摘要： This invention relates to an image encoding method and apparatus, and particularly has as its object to satisfactorily control the amount of encoded image data. In order to achieve this object, according to this invention, there is disclosed a technique for sequentially controlling the code amounts in accordance with accumulated code amount information and accumulated encoded area information, so that variable-length codes of an image fall within a predetermined memory capacity in a single pass. More specifically, in an image processing apparatus having a compression processor (15) for compressing input image information, and a memory (16) for storing encoded data by the compression processor (15), a code amount controller (14) calculates a reference code amount on the basis of the input image information, and controls the encoding condition of the compression processor (15) on the basis of the calculated reference code amount.

摘要： A data transmission system discriminates, for each one of a plurality of pieces of data representing an image provided in a frame, whether the one piece of data is a first type of data, which is to be developed into bit map data in a bit map area corresponding to the frame, or a second type of data, which is not to be developed into bit map data. The first type of data is developed into bit map data in the bit map area in response to the discrimination. Layout information of the second type of data in the frame is generated such that variation or rotation of the developed bit map data can be directed in the layout information. The developed bit map data, the generated layout information, and the second type of data are transmitted separately to an external apparatus.

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.
