Dual-Lens Camera Live View Playback Range Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During live view display, it is challenging to identify the range that will be displayed during playback, especially when using a dual-lens camera where the captured range is identifiable but the displayed range during playback cannot be easily identified.
Innovation Solution
An electronic apparatus is designed to obtain two live view images from different optical systems with a predetermined parallax and display an indicator on one of the images to show the part that will be displayed during playback, allowing the user to identify the range during live view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If two images with parallax are captured using two optical systems for stereoscopic display, then the captured range is identifiable during live view display, but the range to be displayed during playback display cannot be identified
Solution Approach 1:
An indicator image is introduced as an intermediary visual element that bridges the gap between the dual optical system's captured range and the playback display range. The indicator image is superimposed on one of the live view images to visually represent the area that will be displayed during playback, allowing users to understand the display range without adding physical complexity to the optical system itself.
Solution Approach 2:
The indicator image creates a visual copy or representation of the playback display range within the live view interface. By displaying a framed indicator that corresponds to the area to be shown during playback, users can see a copied representation of the future display state, enabling them to compose and capture images with the correct framing in advance.
2Area of stationary object
If dual-lens camera captures entire range during live view display, then all captured content is visible, but the specific part to be displayed during playback cannot be identified
Solution Approach 1:
The live view display is segmented into multiple visual layers: the full captured image from the dual optical system and a superimposed indicator image that segments out the specific playback display area. This segmentation allows users to see both the complete captured range and the specific portion that will be displayed during playback simultaneously.
Solution Approach 2:
The indicator image uses distinct visual characteristics (such as framing lines or overlay graphics) to differentiate the playback display area from the rest of the captured image. This visual differentiation helps users immediately identify which portion will be displayed during playback without confusion.
3Loss of information
If indicator showing playback range is superimposed on live view image, then users can identify display range, but display complexity increases
Solution Approach 1:
Rather than creating a separate physical display device or complex interface, the system creates a two-dimensional graphical copy of the playback range as an overlay on the existing live view display. This approach provides the necessary information while utilizing the existing display hardware, minimizing additional complexity.

AI summary
An electronic apparatus according to the present invention includes: a processor; and a memory storing a program which, when executed by the processor, causes the electronic apparatus to obtain a first live view image corresponding to a first optical image inputted via a first optical system and a second live view image corresponding to a second optical image inputted via a second optical system having a predetermined parallax with respect to the first optical system, and perform control to display, when displaying the first live view image and the second live view image side by side, an indicator indicating a part displayed during playback display in an angle of view of the first optical system such that the indicator is superimposed on the first live view image.
