摘要： An image pickup apparatus comprises a first line sensor and a second line sensor. A first control circuit controls an accumulation time of the first line sensor based on an output signal of the first line sensor. A second control circuit controls an accumulation time of the second line sensor based on an output signal of the second line sensor. A compensating circuit compensates a level difference between a level of the output signal of the first line sensor and a level of the output signal of the second line sensor by setting a control characteristic of the first control means to be different from a control characteristic of the second control means.

The heaters are formed into a plurality of groups and are driven by block drive on a per-group basis. A block selection signal of driving-signal voltage level (VHT) and a heater driving signal corresponding to a selected block are generated based upon a print data signal, which has been input at a logic-signal voltage level (VDD), in any of an input circuit, shift register circuit and decoder circuit. The heater/driver array drives the heaters in accordance with the block selection signal and heater driving signal of the driving-signal voltage level.
