Title: Image processing unit
Inventor: ISHIZAKI HIROMI
IPC: G06T5/00
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent saturation from being deteriorated in the case of edge emphasis processing by subtracting an overflow part from the arithmetic operation result based on a subtraction color designation signal in the case that the arithmetic operation results indicate an overflow. SOLUTION: Image data are given to an edge extract circuit 21 of an image processing block, where an edge quantity is calculated. Then an adder 22 adds a value to original image data in response to the edge quantity. Then the arithmetic operation results are compared by a comparator 24 and a maximum value result is fed to a register 25 by a selector 23. Moreover, a signal to designate a subtracted color is generated. That is, a subtraction color is designated. In the case that the arithmetic operation result overflows, the overflow part is subtracted from the arithmetic operation result by the subtraction designation signal at a subtractor and the result is outputted.  In the case that the arithmetic operation result exceeds an output gradation and the arithmetic operation result is rounded on the output gradation number, other colors are changed to keep the saturation, then the saturation at a high density part is improved.

Abstract: PURPOSE:To contrive a high-speed level conversion by providing a level conversion function and a signal holding function on a level conversion means and switching the level conversion function and the signal holding function based on the state of an output signal of an input buffer means. CONSTITUTION:A level conversion circuit 20 is provided with PMOS transistors(TRs) 401-404 and NMOS TRs 301, 302. For example, when an input signal Vin is at an H level, a TR 102 is turned on and a TR 103 is turned off. Thus, an output signal (a) goes to an H level and an output signal a' goes to an L level. Thus, the TR 401 is turned off and the TR 404 is turned on in the level conversion circuit 20. Conversely, when the input signal Vin is at an L level, the TRs are turned on/off opposite to the above-mentioned operation. Thus, the state of output signals (b), b' is held by the data holding function composed of the TRs 402, 403, 301, 302.

Filed: 1981-10-05
Abstract: PURPOSE:To minimize the number of circuit elements used in the titled circuit and make the configuration of the circuit suitable for an integrated circuit. CONSTITUTION:When an input voltage V1 is higher than the 1st reference voltage VA, a transistor Q2 is turned on among the 1st differential paired transistors, and a transistor Q6 is turned on among the 2nd differential paired transistors, and, correspondingly, electric currents I1 and I2 flow to them, respectively. Under this condition, the electric current I1 flows to transistors Q4, Q9, and Q10 as well as a transistor Q3, and the electric current I2 flows to transistors Q7, Q8, and Q10. Therefore, when looking on the base of a transistor Q11, electric currents entering and leaving this base become zero and the output transistor Q11 is under ''OFF'' condition (output ''0''). When the input voltage V1 is higher than the 1st reference voltage VA and lower than the 2nd reference voltage VB, transistors Q1 and Q6 are turned on and operate so as to set the output transistor Q11 to the ''ON'' condition (output ''1''). When the input voltage V1 is lower than the 2nd reference voltage VB, transistors Q1 and Q5 are turned on and operate so as to set the output transistor Q11 to ''OFF'' condition.
