Multi-Control Image Processing Device Power Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image processing device configuration, where only predetermined functions can be executed during power-saving mode by the sub-control unit, is not user-friendly due to limited control capabilities.
Innovation Solution
An image processing device with multiple control units, including a first and second control unit, where the second control unit sets selected functions as executable and unexecutable based on user input, allowing for mode selection between normal and power-saving modes to enhance user convenience and power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the main control unit is placed in a halt state during power-saving mode, then power consumption is reduced, but the control capability and user-friendly operation deteriorate
Solution Approach 1:
The control unit is divided into a main control unit and a sub-control unit with different functional capabilities. The sub-control unit is designed to handle specific functions independently, allowing it to operate during power-saving mode while the main control unit remains in halt state, thus resolving the contradiction between power consumption and control capability.
Solution Approach 2:
The system dynamically switches between different operational modes: in normal mode, the main control unit handles all functions; in power-saving mode, only the sub-control unit operates with limited functions. This dynamic adaptation allows the system to optimize power consumption while maintaining necessary control capabilities based on operational requirements.
2Loss of energy
If only predetermined functions are executed by the sub-control unit during power-saving mode, then power consumption is reduced, but adaptability and user convenience worsen
Solution Approach 1:
The sub-control unit is designed with multi-functionality to handle various image processing functions independently. By equipping the sub-control unit with diverse functional capabilities, the system allows flexible function selection during power-saving mode, improving adaptability while maintaining power efficiency.
Solution Approach 2:
The sub-control unit is designed to autonomously execute selected functions during power-saving mode without requiring the main control unit to be active. This self-service capability allows the system to maintain operational flexibility and user convenience while the main control unit remains in low-power state.
3Loss of energy
If the second control unit limits functions to those the sub-control unit can handle during power-saving mode, then power usage is optimized, but the quantity of executable functions decreases
Solution Approach 1:
The system changes the operational parameters of the control units based on power-saving mode requirements. The second control unit dynamically adjusts which functions are executable, allowing a subset of functions to operate during power-saving mode. This parameter adjustment resolves the contradiction by optimizing power usage while maintaining a reasonable quantity of executable functions.

AI summary
An image processing device includes a plurality of control units and an accepting unit. The plurality of control units are configured to execute each of a plurality of functions regarding image data, and include a first control unit and a second control unit. The accepting unit accepts a user's selection indicating a function selected by a user. When a control capability of the first control unit has decreased, the second control unit sets the selected function executable and sets the functions other than the selected function unexecutable.
