PROBLEM TO BE SOLVED: To provide an input-output device that increases the number of available applications.SOLUTION: An input-output device includes an input-output part 101 including a pixel portion 101d, an image processing circuit 131, a storage circuit 132 in which a plurality of programs are stored, and a data processing part 103 including a CPU 133. The pixel portion 101d includes a plurality of display circuits 115d to each of which a display selection signal is input and a display data signal is input in accordance with the display selection signal and each of which becomes a display state that corresponds to the data of the input display data signal, and a plurality of light detection circuits 115p for generating optical data in accordance with the illuminance of the incident light. The plural pieces of the optical data are sequentially stored in the storage circuit, the plural pieces of the optical data are sequentially read out as image data from the storage circuit by the image processing circuit, a label is given to a piece of the optical data with a larger value than a reference data value, the number of pieces of the optical data that have been given labels that represent the same group is counted, and a process by the CPU is varied in accordance with the count result.SELECTED DRAWING: Figure 1 |
