CONTROLLING METHOD FOR ELECTRONIC APPARATUS WITH ONE SWITCH BUTTON

A controlling method suitable for an electronic apparatus is disclosed. The electronic apparatus includes a camera module and a switch button. The controlling method includes following steps. A holding duration is measured started from a first time point when the switch button is pressed down. In response to the holding duration ends within a first threshold period, a singular image is generated. In response to the holding duration exceeds the first threshold period and ends within a second threshold period from the first time point, a series of burst images during the holding duration is generated. In response to the holding duration exceeds the second threshold period, a series of burst images during the second threshold period is generated, and also a video is generated.
