Display Device Live View Imaging Range Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unit-type imaging devices lack a monitor for image display and require external devices for live view and image capture operations, leading to inefficient power usage and user burden in managing multiple devices.
Innovation Solution
A display device with an imaging section, display section, and control section that acquires imaging range information from an external imaging device, sets a corresponding area in the captured image, and controls the display of this area on the device's monitor, enabling live view display and reducing power consumption by allowing remote control of image capture operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If continuous image transmission from imaging device to external display device is performed, then live view display is enabled, but power consumption increases
Solution Approach 1:
The imaging device creates a copy of the captured image data and transmits only the essential image information to the display device rather than continuously streaming full-resolution data. This copying approach enables live view display while significantly reducing the power consumption associated with continuous high-bandwidth image transmission.
2Adaptability or versatility
If multiple separate devices (imaging device and external display device) are used, then image capture and display functions are achieved, but user burden increases
Solution Approach 1:
The patent combines the imaging device and display device into an integrated system where the imaging device can function as both the capture device and the display device. The display section of the imaging device directly shows captured images, eliminating the need for users to manually transfer images between separate devices and reducing operational complexity.
3Measurement precision
If imaging range information is acquired from external imaging device, then display area can be accurately set, but device complexity increases
Solution Approach 1:
The control section acts as an intermediary that automatically manages the acquisition and processing of imaging range information. It receives imaging range data from the imaging section, automatically determines the appropriate display area, and configures the display section accordingly. This intermediary approach enables precise imaging range measurement while shielding users from the underlying system complexity.

AI summary
In a display device including a camera section and a monitor, imaging range information indicating an imaging range for the imaging device is acquired. Subsequently, a display target area corresponding to the imaging range indicated by the imaging range information is set in an image captured by the camera section. Then, a partial image in the display target area in the image captured by the camera section is displayed on the monitor. As a result, live view display can be achieved without causing the imaging device to capture a photographic subject at a predetermined frame rate and transmit the captured image.
