Title: Picture processor
Inventor: YANO MASAHISA
IPC: G06T1/00
Filed: 1990-03-14
Abstract: PURPOSE:To use a color pen by the much more kinds of colors with simple processings and configuration by extracting a mark picture and character/ graphic pictures while separating them based on a signal level learnt before reading a document / drawing. CONSTITUTION:A picture input part 1 outputs the signal level to a mode switch part 2 corresponding to a mark on a learning sheet or the document/drawing and/or the density level of the character, graphic or background. In such the case, when the switch part 2 is set to a learning mode, this signal level is outputted to a density level registration part 3. On the other hand, when the switch part 2 is set to an original read mode, the signal level is outputted to a picture classification part 4. The registration part 3 is activated by a signal from the switch part 2 and selects only a signal in the first prescribed area of the learning sheet, and the maximum and minimum values of an average level or the signal level for the selected signal are registered. The classification part 4 is activated by a signal from the switch part 2 and separates the character/graphic and the mark on the document/drawing based on the signal level from the input part 1 and the signal level registered to the registration part 3.

Title: Parallel sorting process method
Inventor: YAMANE YASUO
IPC: G06F15/16
Filed: 1987-03-19
Abstract: PURPOSE:To extremely decrease the data transfer frequency between processors and to improve the processing efficiency by sending the elements of data allocated evenly and previously by each processor to other corresponding processors with each other excluding the allocation amount of its own when a partial charge range is designated. CONSTITUTION:The processors 1-1-1-m receive information from a control processor 4 to divide the range of the data value into (m) partial ranges in the number equal to the number of processors. Then a partial range to which each allocated element belongs is discriminated and sent to the processor to which said partial range is allocated with only the element allocated to its own left as it is. At the same time, the element sent to its own processor via the similar processes carried out by other processors in parallel with each other is received. When the mutual allocation is ended among elements, each processor sorts its own allocated data. Thus a sorting process of whole data is completed. In such a way, the data sorting process is completed just with a single time of transfer of data at most for each element.
