摘要： To provide an image processing apparatus and method that enable high speed and high quality image drawing process. When a drawing instruction including drawing logical arithmetic process instruction is input to a drawing instruction converting unit, the drawing instruction converting mans converts the input drawing instruction to a drawing object and a drawing logical arithmetic process instruction and then stores these to a drawing object storing unit. A drawing logical arithmetic process instruction determining unit determines whether the drawing logical arithmetic process instruction has content to be drawn without logical arithmetic process or not. As a result of determination, when the drawing logical arithmetic process instruction is determined to have content to be processed without drawing logical arithmetic process, the drawing object converting unit converts the determined drawing logical arithmetic process instruction and drawing object to the instruction and drawing object which do not require the drawing logical arithmetic process and transfers the subsequent processes to the other processing unit.

摘要： The present invention provides an image processing device that avoids occurrence of unintended color conversion during the logical operation processing, and produces high-resolution images. In the image processing device of the present invention, after an input color conversion unit converts the RGB color space into the CMYK color space, a first color conversion unit executes color conversion of an area subjected to the logical operation processing into the CMY color space, and a logical operation unit executes the logical operation processing. Thereafter, a second color conversion unit executes color conversion of a logical operation result into the CMYK color space. On the other hand, a pixel value comparison unit compares the color values of the CMY color space before and after the logical operation by the logical operation unit; and if coincident, an output image selection unit selects the color values converted by the input color conversion unit as they are. Thereby, as a result of the logical operation, if the color values of the images are not varied, the original color values in the CMYK color space are adopted as the output result; and therefore, there will not be unintended color conversion executed by the first and second color conversion units.

摘要： Disclosed is an image processing device capable of recognizing a specific image such as an image which is prohibited from printing at high speed and, moreover, without being influenced by an image forming process. A drawing command analysis unit analyzes a drawing command received by a drawing command input unit and sends an analysis result to both an output image data generation unit and a recognition image data generation unit. The output image data generation unit generates output image data adapted to an image formation device in accordance with the drawing command. In parallel with the operation, the recognition image data generation unit generates recognition image data adapted to a recognition unit in accordance with the drawing command. The recognition unit performs a process of recognizing a specific image by using the recognition image data. The recognition image data may have a data format, resolution, a color space, and the number of bits per pixel which are different from those of the output image data. When the specific image is recognized by the recognition unit, the output image data generation unit stops outputting the output image data.

摘要： The present invention provides an image processor and an image processing method wherein a specific image such as an image of which the printing is prohibited can be recognized at high speed and in addition, with high precision. A rendering command analysis unit passes a rendering object to any of a recognition unit for a raster image, a recognition unit for graphics and a recognition unit for a character according to the type of the rendering object in the rendering command and tries to recognize a specific image. The result of recognition by each recognition unit is passed to a recognition determination unit and it is synthetically determined based upon these results of recognition whether the specific image exists or not. Even if the specific image is formed by dividing into plural types of rendering objects, the specific image can be recognized by such recognition processing. Also, processing for generating output image data by an output image data generation unit according to a rendering command and outputting it is executed in parallel with such recognition processing so as to speed up processing.
