摘要： A user specifies image data to be transferred and the conversion form of the image data. An information processing device instructs an image data obtaining device to transfer the specified image data. The transferred image data is converted into data in the form specified by the user. The image data to be transferred and the specification of its conversion form are simultaneously received, so that the image data is transferred and converted at the same time. Accordingly, user operations are reduced and user operability can be improved.

摘要： The present invention concerns an image processing device and an image processing method for processing a decoded image, and its objective is to optimally binarize a decoded original. After the respective density histograms of colors R, G, and B have been drawn, the hierarchical relationship between the low-density-side peak value and high-density-side peak value is investigated. A color component which is to become a binarization object is determined based on the comparison results on the number of color components whose high-density-side peak value is/are higher and the number of color components whose low-density-side peak value is/are higher, and the color of the pixel to be outputted is determined based on the comparison of the pixel with a threshold value.

摘要： A method for detecting a skew of a document image corrects the skew of a document image input from an image scanner, and achieves increased accuracy compared with prior art document image skew detection methods. After segmenting the input document image into regions each having a predetermined width, lines containing black pixels are detected from each of these regions. Then, from a region where the detected lines containing black pixels follow one another in a consecutive manner, a partial image is extracted, the skew angle of the partial image is detected, and the skew angle of the document image is determined based on the thus detected skew angle of the partial image.

摘要： When it is determined whether the color of each cell of an image is black or white from the gradation value of each cell, the determination is made by comparison of the gradation level of the cell with a threshold if the gradation level is sufficiently close to that of black or white. In contrast, if the gradation value of the cell is within a gray zone, the color of the cell is determined from the colors of the cells adjacent to the cell of interest. That is, if the gradation value of the cell is gray and the colors of the adjacent cells are all black, the color of the cell is determined to be white; and conversely if the colors of all the adjacent cells are white, the color of the cell is determined to be black.
摘要翻译： 当从每个单元的灰度值确定图像的每个单元格的颜色是黑色还是白色时，如果灰度级与该单元格的灰度级足够接近，则通过将单元的灰度级与阈值进行比较来进行判断 黑色或白色。 相反，如果单元的灰度值在灰色区域内，则根据与感兴趣单元格相邻的单元格的颜色来确定单元格的颜色。 也就是说，如果单元的灰度值为灰色并且相邻单元的颜色全部为黑色，则单元的颜色被确定为白色; 相反，如果所有相邻单元的颜色为白色，则确定单元的颜色为黑色。

摘要： Compressed print data from a host PC is transferred to the data receiving unit, compressed print data transfer unit and compressed print data storage unit of a printer controller unit, and is transferred to a bitmap data storage unit after being restored to a bitmap by a data restoration/transfer unit. Then, the decompressed print data is output to a printer engine by a bitmap data transfer unit as video signals. The data storage capacity management unit optimally re-distributes storage capacity between two storage areas of the compressed print data storage unit and bitmap data storage unit, according to printing status signals, such as resolution, paper size, warm-up status of an engine, previous frequency of use, transfer speed and the like.

摘要： An image reading apparatus is attached to the top of a PDA. During the image reading operation, an operation state control signal is output from the image reading apparatus to the PDA. According to the signal, the intensity of an input display unit not required during the operation can be reduced. Additionally, the power supply or the supply of a signal not required during the operation is stopped. Furthermore, an LED of the PDA issues a notification of an operation state by lighting, blinking, or turning-off. When the input display unit displays an image, an erect image and an inverted image are appropriately switched depending on the operation state. During an image reading operation, input by input buttons and a touch panel of the input display unit are nullified to avoid the occurrence of a malfunction.
