Camera Control Device Eye Proximity and Touch State Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital camera technologies cannot differentiate between the user's proximity to the viewfinder and their operating state on the rear display, leading to inefficient operation and difficulty in executing specific processes based on these states.
Innovation Solution
A control device and method that utilize a process control unit to execute image-related processes based on detected proximity to the viewfinder and operation state on the rear display, allowing for customizable associations between eye proximity and touch states to optimize shooting and playback operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same display screen is displayed on the rear display regardless of whether the user is bringing an eye close to the viewfinder, then the display consistency is maintained, but the operational efficiency and user experience deteriorate due to inability to execute different processes based on eye proximity state
Solution Approach 1:
The patent applies dynamics by making the display content and operational response dynamic based on the detected eye proximity state. The system automatically adjusts the rear display content and enabled operations according to whether the user's eye is close to the viewfinder, transforming a static display system into a dynamic one that adapts to user behavior in real-time.
Solution Approach 2:
The patent implements feedback by using the eye proximity detection result to control the display and operational state. The detection unit continuously monitors eye proximity, and this information feeds back to the control unit, which then adjusts the rear display content and operational responsiveness accordingly, creating a closed-loop control system.
2Ease of operation
If multiple buttons and operations are required to execute different processes, then the functional versatility is maintained, but the ease of operation deteriorates due to increased number of button presses needed
Solution Approach 1:
The patent applies multi-functionality by enabling the rear display to serve multiple purposes based on eye proximity state. The same physical display unit can show different content (live view, playback, settings) and enable different operations (shooting, playback control, settings modification) depending on the detected eye state, eliminating the need for separate buttons for different modes.
Solution Approach 2:
The patent changes the operational parameters of the rear display based on eye proximity detection. When the eye is close to the viewfinder, the system changes parameters such as enabling playback operations on the rear display and showing playback images, whereas when the eye is not close, different parameters are applied for shooting operations. This parameter-based control reduces the need for multiple physical buttons.
3Measurement precision
If the system detects only eye proximity state without considering operation state, then the detection simplicity is maintained, but the measurement precision deteriorates due to inability to distinguish between different operational contexts
Solution Approach 1:
The patent segments the state detection into two independent components: eye proximity detection and operation state detection. The detection unit separately identifies whether the eye is close to the viewfinder and what operation the user is performing (shooting or playback). This segmentation allows precise state identification without requiring a single complex detection mechanism.
Solution Approach 2:
The patent merges the results of eye proximity detection and operation state detection to determine the overall system state. By combining these two detection results, the system achieves comprehensive state awareness that enables precise control decisions. The control unit integrates both pieces of information to determine appropriate display content and enabled operations.

AI summary
A control device, control method, and program, capable of executing a process suitable for a state of proximity of an eye with respect to a viewfinder, and an operating state with respect to an operation display portion. The control device includes a process control unit that executes a process related to shooting or playback of an image, on a basis of whether proximity of an eye with respect to a viewfinder is detected, and detection of an operation state with respect to an operation display portion.
