A camera installed in a wireless terminal comprises a first electronic zooming means to operate by hardware and a second electronic zooming means to operate by software. The first electronic zooming means quickly select one of several pictures with predetermined scale factor. The second electronic zooming means zoom in or out a picture in small steps. An operator can quickly display a picture of desired scale factor by these two means. Further, in a foldable type terminal with a magnetic sensor, a picture with desired scale factor can be displayed by adjusting an angle between a first housing and a second housing.
