An object of the invention is to provide a display device that allows its useful life to be prolonged without letting the user of the device conscious of changes in the display state of the display device, and the power consumption to be prevented from increasing, and the usable time without charging to be prevented from being shortened even when a light emitting display device is used. The display device is driven by a power source chargeable by connection with an external power source and includes a display portion (), a display control portion () that switches between an inverted display state and a non-inverted display state of said display portion (), and a power source detection portion () that detects a connection with said external power source. The display control portion switches between the inverted display state and non-inverted display state of said display portion () when said power source detection portion () detects a connection with said external power source.

Display apparatus and cellular device

A video telephone is provided which makes it possible to speak while seeing a motion picture of a partner side and while protecting the portrait right of a calling party using the video telephone as the need arises. At the time of communication, an image pickup unit () pickups a photogenic subject () such as a calling party and peripheral environment etc. A pickup signal processing unit () processes a pickup signal corresponding to an image of the photogenic subject () pickup by the image pickup unit () to thereby generate a pickup image signal. A portrait right correspondence image processing unit () subjects the pickup image signal to an image modification processing such as a defocusing processing so as to protect the portrait right of the calling party. An image signal selection unit () is selectively operated, in accordance with an operational instruction based on the determination of the calling party, to transmit a modified image signal subjected to the image modification processing or to transmit the pickup image signal as it is. A communication unit () transmits the pickup image signal from the pickup signal processing unit () or the modified image signal from the portrait right correspondence image processing unit ().
