Image Capturing Apparatus Dual Display Timecode Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing apparatuses face challenges in displaying information while minimizing power consumption, especially when the processing load of the camera is not high.
Innovation Solution
The apparatus includes a first display unit for captured images and a second display unit for image capturing information, with a generating unit creating a timecode corresponding to the frame rate of the image capturing unit. The timecode is displayed on the first display unit at short intervals and on the second display unit at longer intervals to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the timecode is displayed on both display units at short intervals to ensure accurate time information, then the timecode accuracy is improved, but the power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating the display update intervals for different display units based on their specific functions. The first display unit (main display) updates at short intervals to provide accurate timecode information, while the second display unit (subordinate display) updates at long intervals since it serves as a backup or secondary reference. This localized differentiation of update frequencies optimizes power consumption while maintaining timecode accuracy where most needed.
Solution Approach 2:
The patent implements dynamics by making the display update intervals adaptive rather than fixed. The system dynamically adjusts the update frequency of the second display unit based on whether the first display unit is currently displaying the timecode. When the main display is active, the secondary display updates less frequently; when the main display is inactive, the secondary display can update more frequently to ensure timecode availability. This dynamic adjustment resolves the contradiction between accuracy and power consumption.
2Illumination intensity
If the display panel is driven at high frame rates (60 Hz or 30 Hz) to display captured images in live view, then the image display quality is improved, but the power consumption increases when displaying information while power is off
Solution Approach 1:
The patent applies periodic action by implementing different update intervals for different types of display content. The live view image display operates at high frame rates (60 Hz or 30 Hz) to maintain image quality and brightness, while the information display (including timecode) operates at lower update frequencies. This periodic differentiation allows the system to maintain display brightness quality when needed while reducing power consumption during information-only display modes.

AI summary
Some embodiments of an image capturing apparatus include a first display unit capable of displaying a captured image and a second display unit configured to display information related to image capturing, where the apparatus comprises a generating unit configured to generate a timecode corresponding to a frame rate at which an image capturing unit performs image capturing; a first display control unit configured to control so as to display the timecode generated in the generating unit on the first display unit at first intervals; and a second display control unit configured to control so as to display the timecode generated in the generating unit on the second display unit at second intervals that are longer than the first intervals.
