Title: Output compensator for ccd line sensor
Inventor: MURAKAMI SHIGEO
IPC: H04N5/341
Filed: 1989-04-10
Abstract: PURPOSE:To read density of an original picture accurately by correcting an output signal of a CCD line sensor in response to the rate of a charge storage time detected with respect to a referenced charge storage time into a signal at a reference charge storage time. CONSTITUTION:An output signal of a CD line sensor 1 read by scanning an original picture is inputted to a multiplier circuit 4 via an amplifier 2 and an A/D converter 3. A resonance type galvano mirror 5 to scan a light beam receives a drive signal from a control section 6 to detect a rock angle of a rotor and a charge storage time signal generating circuit 7 generates a charge storage time signal (a). The charge storage time signal (a) is given to a ROM 11 as an address signal (d) via a counter 9 and a latch circuit 10. The ROM 11 inputs a change with a setting address corresponding to a reference charge storage time to the multiplier circuit 4. The result of multiplication is inputted to a divider circuit 12, in which the signal is divided by a reference data from a division setting section 13 to obtain an output picture signal Sout compensated corresponding to the reference charge storage time.

Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an input/output buffer circuit which attains its optimum fast operation regardless of the stray capacitance of an input/output terminal by using an auxiliary pull-up transistor resistance that is connected to an external terminal. SOLUTION: When an L level is given from the outside and the voltage of an input/output terminal 17 reaches VIH from VDD, the output of a level detection circuit 13 is kept at an L level and accordingly the output of a NAND circuit 14 is set at an H level with an auxiliary pull-up transistor resistance 15 kept in an OFF state. When a high load is applied to the terminal 17, the resistance 15 is turned on while the voltage of the terminal 17 reaches VIH from VIL that is set by the circuit 13. In other words, the ON period of the resistance 15 is adjusted according to the load of the terminal 17 and the level can be fast decided. Thereby an extremely useful input/output buffer circuit is obtained.
