Title: Image forming apparatus
Inventor: OKUBO MASAHARU
IPC: H04N1/23
Filed: 1990-01-12
Abstract: PURPOSE:To obtain a good multi-value image by controlling the lighting time of an optical signal through comparison of a multi-value analog data with a triangular wave, and adjusting the lighting time for every level of the multi- value analog data. CONSTITUTION:A signal from a digital data input device 21 is output to a D/A converter 22 and converted to an analog quantity. On the other hand, a pattern signal generator 25 generates a pattern signal 30 of a triangular wave once for every predetermined number of pixels of a digital data input from the input device 21. These analog pixel signal 29 and pattern signal 30 are compared by a comparator 24. When the analog pixel signal 29 is larger than the pattern signal 30, a binary image data 31, namely '0' is formed and output. If the former is smaller than the latter, '1' is formed and output as the binary image data 31. A half tone image can be formed by a four-value digital image signal if the lighting time of a semiconductor laser is controlled. If the level of the analog signal is adjusted when the digital image signal is converted to the analog signal by an adjusting means 23 to obtain a better image, the adjustment is achieved in the multi-value level.
