Image Processing Apparatus Standing-Up Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses with low-power consumption modes face challenges in efficiently transitioning back to a printing mode, often requiring users to approach within a limited sensing range, leading to increased waiting time for users and inefficient power management.
Innovation Solution
Incorporating a detector and a change unit that utilize image capturing and comparison to detect a user's standing-up motion after a print instruction, allowing the apparatus to swiftly transition from a low-power consumption mode to a printing mode, readying the device for use.

Engineering Contradiction Analysis
1Loss of energy
If the apparatus uses a low-power consumption mode to save energy, then power consumption is reduced, but the user waiting time increases because the apparatus cannot quickly transition back to printing mode
Solution Approach 1:
The apparatus performs preliminary actions by capturing images of the user before and after the print instruction, and comparing them to detect standing-up motion. This preliminary detection mechanism is activated in advance to enable quick transition to printing mode without requiring the user to approach within a limited sensing range, thus reducing waiting time while maintaining low-power consumption mode.
2Device complexity
If the apparatus requires users to approach within a limited sensing range to wake from low-power mode, then power management is simplified, but user convenience deteriorates due to increased waiting time
Solution Approach 1:
The patent introduces an intermediary mechanism using image capture and comparison technology. Instead of relying solely on proximity-based sensing, the system uses captured images to detect user standing-up motion as an intermediary signal to wake from low-power mode. This intermediary detection method expands the effective sensing range beyond physical proximity, improving user convenience while maintaining relatively simple power management logic.

AI summary
An image processing apparatus includes a detector and a change unit. The detector detects a standing-up motion of a person after receipt of a print instruction. The change unit changes from a low-power consumption mode to a printing mode in response to detection of the standing-up motion, the printing mode being a ready-to-print mode.
