Image Processing Device Dynamic Controller Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices lack an efficient method to modify their operating modes, particularly in transitioning between power-saving modes and executing processes, leading to suboptimal power management and processing efficiency.
Innovation Solution
An image processing device with a detecting unit, processing unit, multiple controllers, a command determination unit, and a load determination unit that activates the appropriate controller to execute processes based on command types and load thresholds, allowing efficient mode transitions and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the image processing device uses a conventional power-saving standby mode with release data triggering, then power consumption is reduced, but the printing wait time increases and responsiveness decreases
Solution Approach 1:
The system dynamically transitions between different operating modes (power-saving mode and active mode) based on real-time conditions. The controller monitors for predetermined events and automatically activates the processing unit when needed, creating a dynamic balance between power consumption and responsiveness without fixed timing
Solution Approach 2:
The controller is configured to detect predetermined events (such as receipt of data, user input, or scheduling signals) in advance and proactively activate the processing unit before actual processing is required. This preliminary detection and activation mechanism reduces wait time by anticipating when power-saving mode should be exited
2Loss of time
If the image processing device activates the controller frequently to improve responsiveness, then printing wait time is reduced, but power consumption increases
Solution Approach 1:
The system changes operational parameters (activation thresholds, event types monitored, processing intensity levels) based on device state and external conditions. By adjusting these parameters dynamically, the system optimizes the balance between activation frequency and power consumption for different operating scenarios
3Use of energy by moving object
If the image processing device uses a simple power-saving mode without event detection, then power consumption is minimized, but adaptability to different operating conditions decreases
Solution Approach 1:
The controller automatically monitors for predetermined events and makes autonomous decisions about when to activate the processing unit without requiring external intervention or complex user configuration. The system serves itself by detecting its own operational needs and responding appropriately, maintaining both low power consumption and high adaptability

AI summary
An image processing device includes a detecting unit, a processing unit, a plurality of controllers, a command determination unit, and a load determination unit. The detecting unit is for detecting a command. The processing unit executes a process for the command. The plurality of controllers controls the processing unit and includes a first controller. The command determination unit determines whether or not the command indicates that the process is to be executed by the processing unit under the control of the first controller. The load determination unit determines whether or not a load required for the process is larger than a prescribed threshold value. While the first controller is in a halted state, if the command determination unit makes a negative determination and if the load determination unit makes a positive determination, the first controller is activated and controls the processing unit to execute the process.
