Title: Remainder calculating device
Inventor: TAKABAYASHI KYOKO
IPC: G09C1/00
Filed: 1988-10-27
Abstract: PURPOSE:To decrease the number of inputs to an adder on an average and to shorten a table generation time by providing an arithmetic means which uses a specific arithmetic result as a process number. CONSTITUTION:A remainder table 108 contains modN corresponding to the respective >=p-q-k (0<=k<p-q) digits of the process number S. When the process number S has a relation r>(p-q-k)/2, a constant which is stored as the table is added to the low-order q+k digits of the S to calculate the complementary number of '1' as to the high-order p-q-k digits of the S, and the remainder table 108 is referred to corresponding to digits where '1' is set to subtract its remainder, thereby finding the remainder of the S. Thus, a certain constant and the remainder corresponding to the digits of the S larger than N are stored as the table 108. Consequently, the numbers of remainders to be added is suppressed to <=1/2 the number of the digits and fast remainder calculation is carried out by a small-circuit-scale addition part 107 and the small-scale table 108.

Abstract: PURPOSE:To obtain a correct RGB signal regardless of the presence of setup of an input signal by selecting a switch so as to change a voltage replacing a blanking part of a video signal and an addition ratio of a luminance signal to a color difference signal. CONSTITUTION:A clamp circuit 15 clamps a back porch part of an inputted video signal to a prescribed voltage, a blanking replacement circuit 30 replaces the video signal inputted from the clamp circuit 15 only when a blanking signal outputted from a synchronizing separator circuit 20 is at an L level into a prescribed voltage level and adjusts a voltage to be replaced in response to the level state selected by a switch 10. Then the video signal replaced to a prescribed voltage by a blanking part is inputted to a variable gain amplifier 40, which varies an amplification factor in response to the level state set by the switch 10. Thus, even when setup exists in the input video signal or not, a correct RGB signal is outputted by the changeover of the switch 10.
