Abstract:
PROBLEM TO BE SOLVED: To provide a communication environment that is comfortable to more users. SOLUTION: Start or stop of a terminal 11 is commanded by depressing a button 91, i.e. the main switch of a terminal 11 in an operating unit 55. By having the terminal 11 depress a button 92 during starting, start or stop of a communication unit 51, i.e. a unit of the terminal 11 for providing a portable telephone function, is instructed. When the terminal 11 is starting, an AV unit 52 for reproducing the data of a content is not stopped, but the AV unit 52 controls a switching unit 54 based on the operation of the button 92. Consequently, power supply from a power supply unit 53 to the communication unit 51 is controlled, and the communication unit 51 is started or stopped. The invention is applicable to a portable audio player. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PURPOSE:To switch the shutter speed in plural degrees with simple constitution by providing a tact switch to an image pickup device having a function to vary the shutter speed. CONSTITUTION:The duty ratio of an overflow drain gate clock OFDG outputted from a timing signal generating circuit 11 is switched in response of the depressing of a shutter key (tact switch) 33 based on an instruction from a microcomputer 3. When the duty ratio of the clock OFDG is witched, the charge accumulating time of the photodetection part 22 of the CCD image pickup device 7 varies, to switch the shutter speed. This switching of the shutter speed is achieved by depressing the shutter key 33, therefore, the hardwares can be simplified and miniaturized. In such a way, the shutter speed can be made switchable in plural degrees with simple constitution.
