Abstract
A mobile-type electronic apparatus is arranged to input an image picked up by a camera to a display circuit through an image pickup circuit and a communication circuit and to display the image on an LCD panel in a state of being enlarged by an enlargement display optical system. In the mobile-type electronic apparatus, a control circuit is arranged to switch the power supply for the display circuit from one state over to another, according to an operation performed on a switch portion, in such a way as to supply electric power only when the use of the LCD panel and a back light is necessary.
