摘要： PURPOSE:To raise the bit rate of a cache, and to speed up the processing of a whole system by using x address and y address of a picture for cache control. CONSTITUTION:The device is constituted of a coordinate calculating means 32a to generate the memory address of a picture after transformation, x and y addresses of an original picture and the memory address of the original picture, a picture element value generating means 32c to generate the picture element value after the transformation from the picture element value of the original picture, and a picture data cache 32b in which the higher order bits of the two-dimensional coordinates x, y are made into a tag and the lower order bits of x, y are made into an index. Then, by generating successively picture elements positioned close to each other on the picture after the transformation, in regard to the picture element to be accessed in order to generate the picture element value of the picture after the transformation as well, the picture elements positioned close are made to be accessed successively. Thus, the bit rate of the cache is raised, and the processing speed of the whole system is accelerated.

摘要： PURPOSE:To increase the continuous processing speed by using line memory for reference line generation, which decodes two-dimensional encoded data, as a line memory for original picture upper line generation which reduces picture data by the four-point interpolation method. CONSTITUTION:Two-dimensional encoded data is inputted to a decoding circuit 14, and this circuit refers to a line memory 12 or 13, where picture data of the like just preceding the decoding object line is stored, to decode inputted two-dimensional encoded data to picture data. Decoded picture data is written in the line memory 12 or 13, where picture data of the line just preceding the decoding object line is not stored, and is sent to a reduction circuit 15 and an interface 16 to an external bus 19. Thus, the processing to decode encoded data to picture data and the processing to reduce decoded picture data are performed at a high speed.

摘要： PURPOSE:To easily grasp which window is open by displaying a window so that the window is leaned. CONSTITUTION:In addition to icons 51 - 53 for window operatings for movement, enlargement, reduction, and entire-surface display, an icon 54 for the leaning operation of the window is displayed at the lower part of the window 2. An operator clicks the leaning icon 54 with a pointing device and the window 2 is displayed as if it were stood against the wall, so that large parts of windows 3 and 4 hidden behind the window 2 in interaction mode are displayed. The operator clicks the window 2 which is displayed in the leaning state and then the window 2 is put back to its last state. Consequently, even when many windows are displayed on the display screen, overlaps of the windows are reduced and the contents of the respective windows can easily be grasped, so which window is open can easily be grasped.

摘要： PURPOSE:To control the increase of LSI packages by providing the increment input to the address of a dynamic random access memory DRAM, producing an address increment signal via an image process means, and switching the data revolving direction by a reading or writing cycle. CONSTITUTION:The address increment signals of the DRAM 100 - 133 containing the address increment inputs serve as the outputs of plural 2nd level comparison means at fall of a row address strobe signal and then as the outputs of plural 1st level comparison means at fall of the column address strobe signal respectively. Thus it is possible to select a memory cell to which each memory package has an access. Furthermore a data revolution means 2 obtains the output data on the memory package and an image process means 1 as the inputs of the means 2. Then the data revolving direction is switched by a reading or writing cycle. As a result, the increase of LSI packages can be prevented.

摘要： PURPOSE:To improve the operability of an operator by processing the preparation of a fringed picture with exclusive OR and constituting image data to a pseudo stereoscopic body. CONSTITUTION:In order to prepare a fringed picture 26, a picture processor 4, microprogram 4a, and image controller 5 are actuated and two copies of an original picture 21 are taken. One copy 22 is parallel-displaced in the X-axis direction by one dot and the other copy 23 is similarly parallel-displaced in the Y-axis direction by one dot. Then exclusive OR are respectively taken by means of the controller 5 between the original picture 21 and displaced copies 22 and 23 so as to obtain the X-axis changing point picture 24 and Y-axis changing point picture 25 of the original picture 21. Then the controller 5 takes the exclusive OR of the picture 24 and 25 and prepares the data of a fringed picture 26. When the data are transferred to a picture memory 8 for display, the fringed picture 26 can be obtained. Therefore, a graphic can be constituted to a pseudo stereoscopic body quickly and easily and the operability of an operator can be improved.

摘要： PROBLEM TO BE SOLVED: To perform discrimination with high reliability and high efficiency by discriminating a paper sheet by reading the image data of the conveyed paper sheet through both an outgoing path and an incoming path. SOLUTION: When a paper money 1 is inserted, a bidirectional paper discriminating device 10 detects the insertion of the paper money 1 through a money reception sensor 2a, drives a conveyance driving mechanism 3 so as to convey the paper money 1 in the direction shown by an arrow (a). lets the paper money 1 pass under discrimination sensor 4 and successively sends read data 5 for discrimination to an arithmetic processing part 6. The arithmetic processing part 6 inputs the data 5 for discrimination, inputs expected value data 8 from a prepared data table 7, compares the respective data and discriminates the truth/false of the paper money 1. Next, it is detected by a money reception sensor 2b the paper money 1 is sent out to the side of the incoming path, and the paper money 1 is conveyed to the sensor 4 for discrimination again. The sensor 4 for discrimination reads the paper money 1 reversely from the outgoing path, sends out its data for discrimination to the arithmetic processing part 6 and discriminates the denomination of the paper money 1.
