Title: Angle detector and image forming device
Inventor: KONAKA TOSHIO
IPC: G06T7/60
Filed: 1992-10-20
Abstract: PURPOSE:To record a straight line with a high quality by reducing jaggy of the straight line. CONSTITUTION:A segmented picture of the straight line having 1/4 inclination is converted into a straight line having 1/2 inclination by thinning to 1/2, and this line having 1/2 inclination is detected by using a template for 1/2 inclination detection. In the same manner, a segmented picture of a straight line having 1/N inclination is detected by using a segmented picture of a straight line having 2/N inclination. One template for i/N inclination detection is used as a template for 2/N inclination detection also. Thus, the angle detector having the same function as conventional is realized with templates whose number is 1/2 of conventional.

IPC: H03H17/02
Filed: 1989-11-01
Abstract: PURPOSE:To cancel a DC component without decreasing the level of a demodulation signal by switching with a selector the input of a register whose DC offset quantity is expected for each prescribed time, and inputting the output of an adder calculating a data difference in the register and an input signal to the register. CONSTITUTION:A subtractor 2 subtracts the output of a shift register 3a from a demodulation output of form the demodulation output of the circuit. An adder 6 adds the output signal of the subtractor 2 and the output of the shift register 3a. A selector 5 selects either output of the adder 6 or an output of the shift register 3a in response to an input switching signal, and inputs it to the shift register 3a. A control section is provided with a timer function and a control section decides a time t0. The input switching signal 4 is changed at the time t0 and holds the content of the shift register 3a after the time t0. Thus, a harmful DC offset to the demodulation signal is cancelled and the bit error rate is improved without losing the signal component.
