Title: Registration deviation detector
Inventor: HIDARI HIROBUMI
IPC: H04N9/093
Filed: 1987-06-25
Abstract: PURPOSE: To accurately detect the quantity and direction of deviations in registration at a high speed by multiplying respective difference signals among primary color signals by a differential signal generated by differentiating the sum signal of the respective R, G, and B signals respectively.  
     CONSTITUTION: The R, G, and B signals are summed up and differentiated. A positive error signal (h) is obtained by multiplying the obtained differential signal (e) by the difference signal (f) generated by subtracting the R signal from the G signal and a negative error signal (i) is obtained by multiplying the differential signal by the difference signal (g) generated by subtracting the B signal from the G signal. Namely, when the R signal is delayed behind the G signal, the error signal (h) is positive and when the B signal leads the G signal, the error signal (i) is negative. Thus, the quantity and direction of the deviations in registration are accurately detected at a high speed with the relatively simple constitution.

IPC: G06F12/00
Filed: 1990-06-19
Abstract: PURPOSE:To reduce user's load by adding a garbage collection mark bit indicating moved data to each data moved to an unused dynamic data storing area by garbage collection. CONSTITUTION:At the time of executing garbage collection, an underflow area 12a in a used dynamic data area 12 is completely copied to a fixed data area 11 and data in other areas are transferred to an area starting from the head of the unused dynamic data area 13. Thereby, an idle area 13a having size equal to the area 12a in the area 12 is generated in the area 13. A garbage collection mark bit is added to a data, an unused data list is formed and the list part is effectively used equivalently with the idle area. Consequently, the garbage collection itself can be accelerated and user's load can be reduced.
