Abstract: Stored digital data is searched for on the basis of an input image, difference information is extracted by comparing the retrieved digital data and the input image, and the difference information is composited to the digital data. Digital data generated by composition is stored. When no digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data. Obtained region segmentation information and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. A user designates the specific region by designating rectangular blocks in an image using a pointing device.

Abstract: A rasterizer generates bitmap images of RGB on the basis of object data inputted from a printer driver and stores the result in an image memory. The rasterizer brings attribute information representing attributes of the input object data into correspondence with each pixel of the generated bitmap images to store in an attribute map memory. An image processing unit converts RGB bitmap images stored in the image memory into binary bitmap data for each of YMCK colors which can be processed by an image forming unit. The contents of conversion processing such as dither matrix for binarization processing are switched on the basis of the attribute information retained in the attribute map memory.

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: A color image processing apparatus converts a first color signal (RGB signal) stored in a frame memory for displaying on, e.g., a CRT color monitor into a third color signal (R'G'B' signal) whose color image information is used for permanent visible representation by a printer, and outputs the third signal in order to effectively adjust differences between color gamuts of different devices. In the conversion processing, a conversion function for directly converting the first color signal into the third color signal is obtained by synthesizing three functions, namely, a first conversion function for converting the first color signal into a standard color space signal, a second conversion function for converting the standard color space signal into the third color signal, and a third conversion signal for converting the standard color space signal into another standard color signal suitable for a color gamut of the printer. The first color signal is converted into the third color signal in accordance with the new synthesized conversion function.

A first discriminating device discriminates whether the image represented by the input image data is a first predetermined image, and a second discriminating device discriminates whether the image represented by the input image data is a second predetermined image different from the first predetermined image. An output device combines discrimination results of the first and second discriminating devices and outputs a discrimination signal. The first and second discriminating devices perform the discriminating operations in parallel.
