摘要： Separately providing a shift register for performing serial-to-parallel conversion on a BD signal and a shift register for performing parallel-to-serial conversion on a bit pattern to generate a PWM signal increases the scale of a circuit for adjusting a writing start position in the scanning direction of a light beam. Therefore, the shift register for performing serial-to-parallel conversion on a BD signal and the shift register for performing parallel-to-serial conversion on a bit pattern to generate a PWM signal are configured as a common register.

摘要： A synchronizing circuit and a timing adjusting circuit set a position of an exposure area by beam scanning as an additional value of a first setting value set in dot unit corresponding to the scanning of a pixel clock period and a second setting value set in tap unit corresponding to the scanning of a period smaller than the pixel clock period. A CPU controls the synchronizing circuit and the timing adjusting circuit so that the exposed position becomes an objective position. The CPU changes the second setting value to a first predetermined value by increasing the first setting value by one dot, in the case that the additional value is increased to reach a first threshold. Further, the CPU changes the second setting value to a second predetermined value by decreasing the first setting value by one dot, in the case that the additional value of the synchronizing circuit and the timing adjusting circuit in which the first setting value is increased by one dot is decreased to reach a second threshold smaller than the first threshold.

摘要： A time delay and integration charge coupled device includes an array of pixels and a clock generator. The array of pixels is distributed in a scan direction and a line direction perpendicular to the scan direction in which at least some of the pixels of the array include three or more gates aligned in the scan direction. The clock generator provides clocking signals to transfer charge along the scan direction between two or more pixel groups including two or more pixels adjacent in the scan direction. The clocking signals include phase signals to transfer the charge to an adjacent pixel group along the scan direction at a rate corresponding to the velocity of the target by driving the gates of the two or more pixel groups and generating a common potential well per pixel group for containing charge generated in response to incident illumination.
