Abstract: According to this invention, encoded data of a target data amount is generated by one image input operation while both lossless encoding and lossy encoding are adopted. For this purpose, a first memory stores encoded data of a shorter encode length among encoded data generated by a first encoding unit which performs lossy encoding and encoded data generated by a second encoding unit which performs lossless encoding. A second memory stores encoded data from a second encoding unit. When an encoding sequence control unit determines that the encoded data amount in the first memory has exceeded the target data amount, the encoding sequence control unit discards data in the first memory, sets a quantization parameter for a higher compression ratio for the first encoding unit, and causes the first encoding unit to execute encoding. Encoded data before the encoded data amount is determined to have exceeded the target data amount is re-encoded by a re-encoding unit.

Abstract: In a case of recording (printing) an image including texts and thin lines, the image is printed with an intended thickness without causing a crack in the thin lines. When the CAD mode is OFF in the apparatus proposed by this invention, assuming a pixel value indicative of a printing color component is 8 bits and the maximum value is 255, the value is reduced to, e.g., 90%, before halftoning is performed, and image forming is performed in accordance with the characteristic curve 751 which specifies the relation between the halftoning-processed data and the amount of exposure light. On the contrary, when the CAD mode is ON, halftoning is performed without reducing the pixel value indicative of a printing color components, and image forming is performed in accordance with the characteristic curve 753 which specifies the relation between the halftoning-processed data and the amount of exposure light.

Abstract: This disclosure relates to an image processing system which can eliminate white gaps which are highly likely to be generated in, e.g., a non-contact color developing system by a simple arrangement, and can output a high-quality image. If it is determined that a white gap process is required, the flow advances to check if the converted data indicates a primary color (single color). Other colors undergo a gradation level reduction process, and a laser is minimally and uniformly turned on (background exposure) at a level which is imperceptible to the human eye by always setting level 1 (data of minimum, invisible level) so as to generate output information with a light amount at an invisible or non-developing level or less, thereby eliminating white gaps.

Abstract: An information processing apparatus includes a composition device for composing document data, graphic data and image data. The document data to be composed is stored in a storage device in a form that is independent of the capacity of an output device. An output control device converts, in accordance with the capacity of the output device, the stored document data upon output to the output device, and controls the output device for outputting the converted document data.

Abstract: An image processor realizes a gradation function and prints and records color information sent from a host computer, as a high-definition and multi-halftone level image. The processor fetches PDL data into an input buffer by interrupt processing, and interprets an input PDL command in accordance with language specifications. If the input data is a drawing command, the input data is converted into a page object format supported by a hardware renderer. Subsequently, as pre-processing for rendering the page object, a determination is made if banding rendering (banding) processing is possible.

Abstract: Plural range images having different resolutions are generated from an input range image and normal vectors are calculated for each generated range image. An edge map is formed for each of the plural range images based on the calculated normal vectors and a single edge map is formed by synthesizing the plural formed edge maps. Polygon data describing the surface shape of an object represented by the input range image are formed based on the synthesized edge map. Polygon data of high precision that represents characteristics of the surface shape of the object is thereby formed with little data.
