Title:
電圧変化検出装置
Document Type and Number:
Japanese Patent JP4517397
Kind Code:
B2
Abstract:
To provide a device for detecting voltage variation for accurately detecting the variations in the voltage of a power supply in an electronic apparatus with large variations in the load current.
When it is detected that an operation mode is set by a CPU 12 or a prescribed operation has been carried out, thresholds VL1, VL2, VL3 for the detected operation mode, times T10, T12, T13, and pause period T20 are read out from a memory 22. As shown in Figure 5, when a detected voltage value V is smaller than a voltage threshold VL1 for the photographic mode in the step S40 and the time T10 elapses under the condition V
