<p><P>PROBLEM TO BE SOLVED: To provide a portable electronic equipment with camera function which prevents abnormal rise of the temperature of a case by abnormal lighting of an LED as a power source. <P>SOLUTION: The portable electronic equipment with the camera function comprises an LED 103, an LED power supply circuit 102 which transforms the power supplied from a power source 104 into a prescribed voltage and supplies to the LED 103, a CPU 101 which sends an operation control signal to the LED power supply circuit 102 and controls the LED power supply circuit 102, and a photographing device for producing an image data, and illuminates the object by the LED 103. The equipment, furthermore has a temperature monitor circuit 105 which relays the operation control signal sent from the CPU 101 and monitors the status of the LED 103, and the temperature monitor circuit 105 outputs an operation control signal for stopping the operation of the LED power supply circuit 102 to the LED power supply circuit 102 when abnormality of the LED 103 is detected. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
