Dual Display Panel Control for Power Optimization in Imaging Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses with single display panels face challenges in effectively managing display operations across multiple operation periods, leading to inefficient power usage and suboptimal user and subject-side displays.
Innovation Solution
The implementation of an imaging apparatus with two display panel units, one for the user side and one for the subject side, controlled by a central processing unit (CPU) that manages display states and content across various operation periods, including monitoring, recording, preview, playback, and moving image recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two display panel units are provided (one for user side, one for subject side), then display effectiveness for both user and subject is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the display panel units dynamically controllable - the control unit switches between different display modes (both panels on, only user panel on, only subject panel on, both panels off) based on the current operation period and visual recognition conditions, optimizing power consumption while maintaining display effectiveness when needed
Solution Approach 2:
The patent applies local quality by enabling independent control of each display panel unit's display content and state - the first display panel unit and second display panel unit can display different content simultaneously, allowing tailored display optimization for each panel based on its specific viewing context and operational requirements
2Ease of operation
If display content is differentiated between two panel units across operation periods, then display suitability is improved, but control complexity increases
Solution Approach 1:
The patent applies universality by designing the control unit to handle multiple display scenarios and operation periods through a unified control mechanism - the same control unit manages monitoring period, recording period, preview period, and playback period displays across both panel units, reducing overall system complexity despite the varied display requirements
3Loss of energy
If display operations are adapted based on operation period and visual recognition, then power efficiency is improved, but detection and measurement difficulty increases
Solution Approach 1:
The patent applies feedback by using the visual recognition unit to detect whether a subject is present and providing this information back to the control unit, which then adjusts the display panel operations accordingly - this closed-loop feedback mechanism enables automatic power optimization without requiring complex manual detection systems

Function Achieved in This Case
This configuration enables efficient display management, ensuring suitable and effective displays for both the user and the subject while minimizing power consumption by adapting display operations based on the current operation period and visual recognition possibilities.

AI summary
An imaging apparatus includes: a first display panel unit for executing display toward a user side; a second display panel unit for executing display toward a subject side; an imaging processing unit for subjecting incident light from the subject side to photoelectric conversion to obtain a captured image signal; a recording processing unit for executing a recording process to a recording medium regarding the captured image signal obtained at the imaging processing unit; and a control unit for controlling the display states of the first display panel unit and the second display panel unit for each of a plurality of various types of operation periods changing along with the operation of the imaging processing unit or the recording processing unit, and executing display control wherein the first display panel unit and the second display panel unit can have different display content during at least a single operation period.
