Abstract:
An electronic device capable of detecting a difference in the way of touch is provided. An electronic device capable of detecting a difference in the way of touch with a small number of components is provided. An electronic device capable of executing various types of processes with simple operation is provided. The electronic device includes a control portion and a display portion. The display portion has a function of displaying an image on a screen and includes a detection portion. The detection portion has a function of detecting a touch operation and a function of imaging, at least twice, a detection object touching the screen. The control portion has a function of calculating a difference between the area of the detection object in first imaging and the area of the detection object in second imaging to execute a different process depending on whether the difference is larger or smaller than a reference.
