摘要： When inputted pixels from an input DMA unit, a packing unit outputs data package. One data package consists of α inputted pixels. A memory control unit writes, on a write line memory at a write interval, the data package that is outputted by the packing unit. The write interval is α times longer than an input interval at which the pixels are inputted into the packing unit. During the writing process, the memory control unit reads out another data package from a read line memory at a read interval that is the same as the input interval. In addition, the memory control unit treats the write line memory as the read line memory, after completing the writing process. Alternatively, the memory control unit treats the read line memory as the write line memory, after completing the reading process.
摘要翻译：当从输入DMA单元输入的像素时，打包单元输出数据包。一个数据包由α个输入的像素组成。存储器控制单元以写入间隔在写入行存储器上写入由打包单元输出的数据包。写入间隔比将像素输入到打包单元的输入间隔长α倍。在写入处理期间，存储器控制单元以与输入间隔相同的读取间隔从读取行存储器中读出另一数据包。此外，在完成写入处理之后，存储器控制单元将写入行存储器视为读取行存储器。或者，在完成读取处理之后，存储器控制单元将读取行存储器视为写入行存储器。

摘要： An image processing apparatus includes (i) a repulsive force generating section for setting repulsive force values RVa and RVu of a quantized pixel according to an output pixel value of the quantized pixel, (ii) a repulsive force calculating section for calculating a repulsive force value RVC to be used in quantizing a quantization-target pixel by attenuating, according to a distance between the quantized pixel and the quantization-target pixel, the repulsive force values RVa and RVu set for the quantized pixel; and (iii) a threshold value correcting section for correcting a threshold value T used in quantizing the quantization-target pixel according to the repulsive force value RVC. This makes it possible to prevent an increase in the number of processing steps and amount of processing when an image is processed with an error diffusion method. At the same time, it is possible to prevent decrease in image uniformity and formation of a pattern unique to the error diffusion method.

摘要： A storage process section stores, into an exceptional reference image list, discrimination information for discriminating a reference image which permits image processing and a reference image which forbids or restricts image processing. In case where a maximum value of a similarity calculated by a voting process section is not less than a threshold value, a control section determines whether a reference image having a maximum similarity is the reference image which permits image processing or a reference image which forbids or restricts image processing and determines whether or not it is necessary to forbid or restrict image processing with respect to input image data in accordance with a result of the determination. This makes it possible to prevent erroneous determination from forbidding execution of image processing based on input image data or to prevent erroneous determination from allowing execution of image processing based on input image data.

摘要： A pseudo-random number generator comprises a controller, a plurality of LFSRs, a FIR filter and a normalizer. The pseudo-random number generator initializes the LFSRs in such a manner that each LFSR has a predetermined phase difference with the other LFSRs, sets the coefficient of the FIR filter in accordance with the desired frequency characteristic of a noise signal, and sets a parameter in the normalizer. The operation of the LFSRs is started, thereby acquiring a noise signal having the desired frequency characteristic.

摘要： An asymmetrical multiprocessor system includes a plurality of processors. At least the first processor and the second processor are asymmetrical to each other. The plurality of processors execute a plurality of unit jobs, workloads for which are foreseeable, the unit jobs being allocated job by job to the plurality of processors. For this purpose, a unit job list, which is used as reference information when the unit jobs are allocated to the plurality of processors, are prepared. Based on the unit job list, unit job scheduling is performed, so as to determine in what order the unit jobs are to be executed, and to which processor the unit jobs are to be allocated. With this arrangement, it is possible to attain a high capability with less hardware resources.

摘要： The present invention provides an image processing apparatus capable of preventing deterioration of judgment accuracy when performing document matching process. To be more specific, when selecting feature points in the neighborhood of a target feature point, a predetermined number of feature points are selected after excluding a prespecified number of feature points in turn from the feature point nearest to the target feature point. For example, when the plurality of feature points are selected, the plurality of feature points, after excluding at least a feature point existing at a position nearest to the target feature point, are selected. Thereby, without increasing the amount of feature points for calculation of features (feature vectors), it is possible to prevent the deterioration of judgment accuracy.
