摘要： In a data recording and reproducing apparatus which records and reproduces a record medium in which at least two kinds of data having different data types can be recorded, data are read out from the record medium, and a digital watermark is detected from the data read out. The kind of data is determined depending upon whether the digital watermark is detected, and it is determined whether retry processing at the time of reading-out the data and verifying processing at the time of writing should be executed. The retry processing or the verifying processing are executed only for the data which is determined that the retry processing or the verifying processing should be executed. Therefore, in the case of data whose reading-out continuity is more important than reliability, the retry processing is omitted, so that time required for reading-out processing can be shortened. In the case of data whose recording continuity is more important than reliability, the verifying processing is omitted, so that time required for writing processing can be shortened.

摘要： Translation handles are set on vertices of a conversion source image frame by a mouse. Frame move processing, enlargement/reduction processing, rotation processing, and deforming processing are performed in accordance with the number and positions of the set translation handles. The image within the frame is operated in accordance with the shape of the conversion source image frame, and the operated image is displayed within the conversion destination image frame. In geometric conversion which requires enlargement/reduction and rotation and preserves parallelism of lines, image conversion is performed by one processing including addition instructions and not including multiplication and division calculations.

摘要： In processing of a minimizer average error method (or an error diffusion method), a threshold value for determining whether a point (pixel) as an object to be processed is a black or white dot is changed in accordance with the pixel position using a threshold value matrix having a two-dimensional repetitive pattern. When a one-dot size in an output apparatus which can only perform binary expression in units of pixels is larger than a logical size, a continuous tone image is converted into a pseudo half tone image in consideration of an increase in size of a dot into other dots (projecting portions).

摘要： A binary data compression and exansion processing apparatus of this invention has an input data holding section for holding input code data. In an address section, bit data having a predetermined length is selected from code data held in the holding section in accordance with an instruction from an addition section, and address data for a decode section is generated from instruction data from a control section and the selected data. The decode section generates data associated with the run length in response to the generated address data, and outputs data indicating the length of the decoded code data portion. The addition section adds the data indicating the length to the previous instruction, and outputs sum data as the next instruction. When the sum data becomes equal to an input bit width, the control section outputs an instruction to the input data holding section so as to input the next code data. Therefore, the decoding processing apparatus of this invention can parallel-process input code data in a pipeline manner.

摘要： In a one-chip high density arithmetic control unit capable of prefetching user's instructions from main memory, an arithmetic logic unit (ALU) subtracts the contents of a location counter holding the address of the next instruction to be executed, from the contents of a memory address register holding an address into which data will be written. The difference is fed through the gates connected to the ALU for determining whether or not prefetched instructions will have to be refetched. An address matching mechanism provided outside the one-chip arithmetic control unit includes a comparator for comparing memory addresses to a preset execution stop address. The output signal of the comparator is stored in a memory section which is provided to correspond to the prefetched instruction buffer, and when an instruction stored in the prefetched instruction buffer is transferred to an instruction register, the signal stored in the corresponding memory section is also read out and used to determine whether to stop execution. Further, whenever access is made to main memory a signal indicating whether the access is legal is externally generated and may be stored in a second memory section. Like the address matching signal, this signal is read out when the corresponding instruction from the prefeteched instruction buffer is transferred to the instruction register. An illegal address interruption is produced when this signal indicates that the address was illegal.
