Title: Image processor
Inventor: HOSHI KAZUNORI
IPC: G06T3/00
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain an image processor which form an image having no outline even in the case of out-area erasure by varying the generation timing of an area signal. SOLUTION: Which area is processed by out-area erasure is previously set. The contents of image processing corresponding to a read image are written to a bit map memory and the processing contents and image data are put together and outputted. Whether or not out-area erasure is set is outputted as selected timing by controlling a selector. Here, selection in other modes is enabled by the same constitution although selection is done by the mode of the out-area erasure. Thus, when the out-area erasure is performed, control can be so carried out that a border part is not included by making the area signal shorter than usual. Consequently, the out-area erasure which does not include the border is enabled even when tuning is so carried out that a border part is intruded for painting-out processing for a closed loop.
Patent JP-2001202243-A (JP)
Title: Data processor
Inventor: MITSUISHI NAOMIKI
IPC: G06F9/40
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a data processor for increasing the number of general registers while maintaining high order interchangeability. SOLUTION: Register designation information for designating a register is divided into two parts. The two parts are arranged by different basic units on the basic units of an instruction code. One instruction code is made to be erasable, and when the erasable instruction code is erased, a control part(CONT) tacitly presumes the prescribed register designation information, and performs a register selection operation. Thus, it is possible to erase the erasable instruction code by using only a tacitly assignable general register (existing general register), and to prevent the increase of the instruction code. At the time of using at least a general register equivalent to the conventional one, the instruction code equivalent to the conventional one is used. Thus, a processing speed can be prevented from lowering by preventing the increase of the instruction code.

Meanwhile, when the switch 74 is opened, the CPU 55 judges that the spectrocolorimeter 1 stands alone. And, an intermittently measuring mode in which lighting and putting-out of the source 11 are repeated at respective measurements is set.
