A method for controlling an analog/digital converter circuitry includes generating a digital signal by accumulating a predetermined increment at a predetermined time interval in accordance with a value of a first analog signal input to the analog/digital converter. The digital signal is converted to a second analog signal, the second analog signal is subtracted from the first analog signal, and a detection signal is generated in accordance with a subtraction result. An accumulation mode is selected from accumulation modes in accordance with the detection signal and accumulation is performed at the time interval and in the increment in accordance with the selected accumulation mode.
