Self-Timer Countdown Display Size Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-timer image capturing systems face challenges in displaying countdown timing effectively, as the display size needs to be adjusted based on the distance between the camera and the subject, but incorporating a distance sensor increases costs.
Innovation Solution
An imaging control apparatus that adjusts the count display size based on the set time of the self-timer, displaying it in a larger size for longer times and a smaller size for shorter times to ensure the countdown is easily readable without obstructing the view of the subject.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display size of the countdown is enlarged to make it readable at a distance, then the readability is improved, but the display obstructs the user's view of the subject when the distance is short
Solution Approach 1:
The display control unit dynamically adjusts the display size of the countdown based on the self-timer setting. When the self-timer time is equal to or larger than a first predetermined time, the countdown is displayed with a first size (larger). When the self-timer time is smaller than the first predetermined time, the countdown is displayed with a second size (smaller). This dynamic adjustment resolves the contradiction by adapting the display size to the appropriate viewing distance implied by the self-timer setting.
Solution Approach 2:
The invention changes the display parameter (size) of the countdown based on the self-timer time parameter. By establishing a relationship between the self-timer time and display size, the system automatically selects the appropriate display size without requiring additional sensors or manual input, thus resolving the contradiction between readability and view obstruction.
2Adaptability or versatility
If a distance sensor is added to measure the distance between camera and subject, then the countdown display can be adjusted according to actual distance, but the cost increases
Solution Approach 1:
The system uses the existing self-timer time setting as a proxy for distance information. Since longer self-timer times typically imply greater camera-to-subject distances, the display control unit can infer the appropriate display size from the self-timer setting itself, without needing external distance sensors. This self-service approach maintains adaptability while avoiding additional costs and complexity.
Solution Approach 2:
The invention uses the self-timer time setting as an intermediary parameter to represent distance information. Instead of directly measuring distance with a sensor, the system uses the self-timer setting (which correlates with distance) as a mediator to determine the appropriate display size, thereby achieving adaptive display without additional hardware.
3Loss of information
If the countdown display size is fixed at a large size, then readability at distance is improved, but the display obstructs the view when the camera is held close to the subject
Solution Approach 1:
The display size is made dynamic rather than fixed. The display control unit automatically switches between the first size (larger) and second size (smaller) based on the self-timer time setting, allowing the system to adapt to different operating conditions without requiring manual intervention from the user.
Solution Approach 2:
The display parameter (size) is changed based on the self-timer time parameter. This parameter-based control allows the system to automatically adjust the display size to match the intended usage scenario, improving both readability and ease of viewing the subject depending on the camera-to-subject distance implied by the self-timer setting.

AI summary
An imaging control apparatus includes a setting unit configured to set a time of a self-timer, a control unit configured to control image capturing to be performed upon a lapse of the time set by the setting unit from when an image capturing instruction is issued, and a display control unit configured to control a count display to be displayed with a first size in a case where the time set by the setting unit is equal to or larger than a first predetermined time, and to control the count display to be displayed with a second size smaller than the first size in a case where the time set by the setting unit is smaller than the first predetermined time.
