Control apparatus, array-type sensor, sensor usage method, control method, and program

A control method of a control apparatus which is configured to control an array-type sensor including an array part in which unit cells having sensor elements and select transistors are two-dimensionally arranged, a plurality of first lines connected to gates of the select transistors, and a plurality of second lines connected to one of sources and drains of the select transistors, the control apparatus comprising:

• a first selector/driver which is configured to select and drive one of the plurality of first lines;
• a second selector/driver which is configured to select and drive at least one of the plurality of second lines;
• a read/arithmetic circuit which is configured to read outputs of the respective unit cells and perform a correction operation on the outputs;
• and a nonvolatile storage device which is configured to store reference data,
• the control method executing:
• storing sensor outputs of the respective unit cells with respect to two or more reference inputs as the reference data in the nonvolatile storage device in a calibration mode;
• and
• performing a correction operation on the sensor outputs of the respective unit cells using the reference data stored in the nonvolatile storage device and outputting results of the correction operation in a measurement mode,
• wherein a plurality of unit cells having different functions are formed using sensor elements of two or more types having different functions as the unit cells, and
• wherein the plurality of unit cells having different functions are two-dimensionally arranged.
