Abstract

<P>PROBLEM TO BE SOLVED: To automatically switch off the illumination lit by an arbitrary operation of a user. <P>SOLUTION: The illumination using an LED requires the operation to switch off the illumination after having lit. The user starts a camera function by an arbitrary operation (S1). Next, when the user carries out the operation of illumination lighting (S2), an illumination section 7 lights up(S3). When the user depresses a photographing button, a camera section photographs (S4) and transmits an imaging data to a controller 2. When the controller 2 receives the imaging data (when YES in S5), the controller recognizes the data as the completion of photographing and switches off the illumination section 7 (S6). The controller 2 does not switch off the illumination section 7 unless the imaging data is received (when NO in S5). <P>COPYRIGHT: (C)2006,JPO&NCIPI

  Thus, it has been necessary to turn off the illumination for a camera using an LED as a conventional illumination element by a user operation. Therefore, if the operation of turning off the light is not performed, the illumination of the LED that consumes about 0.3 W is a factor that shortens the battery life. Further, there is a problem that the LED deteriorates when it is lit for a long time. Further, since shooting is not performed during the menu operation, it is not necessary to turn on the illumination, and it should have been turned off to reduce power consumption. Further, when the foldable mobile phone is closed, the shooting is temporarily interrupted. In this case, too, the light should be turned off to reduce power consumption.

  In addition, lighting using a xenon tube used in a general camera, so-called strobe, has a lighting time determined by the characteristics of the lighting element, and it was not necessary to control the lighting off, but the LED needs to control the lighting off There is. The reason why LED elements are generally used in camera-equipped mobile phones is mainly because the size can be reduced as compared with the case of using a xenon tube.
