PROBLEM TO BE SOLVED: To generate plural ramp function signals in parallel by allowing a ramp function signal generator to generate the signal value of a ramp function signal according to a specific formula. SOLUTION: The ramp function signal generator of a solid function signal generator generates a signal value R of a ramp function signal according to a specific formula; R=Ah+Bv+C. In the formula, coefficients A-C are positive and negative values, and the signal value R is generated for each pixel h of the group of pixels h existing on each scanning line v of the group of scanning lines v, and the coefficients A-C are generated by a coefficient generator under the control of a control means. Also, the ramp function signal is generated so that the value of the coefficient A can be made the same, and the value of the coefficient B can be made the same among the ramp function signals under the control of the control means. For example, ramp function signal generators 330-33n are controlled in the same format by a multi-controller 333 in this generator system.
