AI Technical Summary
Existing image reading devices experience increased power consumption when switching from low-power mode to high-power mode, making it difficult to effectively manage the balance between power consumption and reading functionality.
The image reading device has a low output mode and a high output mode. It automatically adjusts the power supply and reading speed according to the type of connected USB device. In the low output mode, it performs image reading at a first reading speed, while in the high output mode, it can achieve a faster second reading speed.
It enables flexible adjustment of reading speed under different power supply conditions, reduces fluctuations in power consumption, and improves the efficiency and controllability of power management functions.
