Image Capture Display Control for Shooting Time Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of video cameras struggle to recognize the difference between actual shooting time and playback time when using slow or fast recording modes, leading to unintentionally long or short moving images due to the disparity in recording and playback times.
Innovation Solution
An image capturing control apparatus and method that allows users to select settings with different ratios of shooting time to playback time, displaying corresponding shooting and playback times to help users understand the time relationship, with the apparatus featuring a CPU, image processing unit, display, and operation unit to manage these settings and display the time ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If slow recording or fast recording is performed with different shooting speeds, then the shooting time and playback time become different, but the user cannot easily recognize the difference between actual shooting time and playback time
Solution Approach 1:
The display control unit provides visual feedback by showing both the shooting time and playback time on the display unit. This feedback mechanism allows users to see the time ratio relationship before shooting, preventing unintentional long or short recordings by making the time transformation transparent.
Solution Approach 2:
The display unit acts as an intermediary between the shooting settings and the user's understanding. It translates the abstract time ratio concept into concrete, visible time representations, mediating the information gap between the shooting parameters and user comprehension.
2Productivity
If fast recording is performed at high speed (e.g., 1200 times faster), then the playback time becomes extremely short (e.g., 3 seconds from one hour shooting), but the user may not recognize this extreme compression
Solution Approach 1:
The system performs preliminary display of the time relationship before the shooting actually occurs. By showing the shooting time and playback time in advance, users can make informed decisions about their shooting settings, preventing unintentional extreme compression or expansion of playback duration.
Solution Approach 2:
The display control unit uses different colors to distinguish between shooting time and playback time representations. This visual differentiation helps users immediately recognize which time value corresponds to which phase, making the time compression or expansion relationship intuitive and easy to understand.
3Measurement precision
If the shooting time is displayed as a fixed value, then the playback time varies significantly across different settings, making it difficult to compare settings
Solution Approach 1:
The display control unit applies different display strategies based on the shooting time length. For short shooting times, it prioritizes displaying shooting time; for long shooting times, it prioritizes displaying playback time. This localized adaptation simplifies the display information while maintaining measurement precision.

AI summary
There is provided an image capturing control apparatus. A selection unit selects, as a setting relating to shooting of a moving image, any of a plurality of settings having respectively different ratios of a shooting time to a playback time. A display control unit performs control: such that a predetermined shooting time and a playback time that corresponds to the predetermined shooting time and is different for each setting are displayed for a setting in which a shooting time is shorter than a playback time, out of the plurality of settings; and such that a predetermined playback time and a shooting time that corresponds to the predetermined playback time and is different for each setting are displayed for a setting in which a shooting time is longer than a playback time, out of the plurality of settings.
