Dual-Optical Live View Zoom Target Selection in Electronic Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital cameras with two lens optical systems do not clearly indicate which live view image to enlarge when a zoom instruction is given, leading to ambiguity in selecting the zoom target area.
Innovation Solution
The digital camera is equipped with an obtaining unit to combine images from two optical systems, a setting unit to designate a target area based on user input, and a display control unit to control the enlargement of this area, ensuring the target area is clearly defined within one of the images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two live view images are displayed side by side from two optical systems, then the user can observe both images simultaneously, but it becomes ambiguous which image should be enlarged when a zoom instruction is given
Solution Approach 1:
The display screen is segmented into multiple regions, with each region dedicated to displaying a live view image from a specific optical system. This spatial segmentation allows users to clearly identify which image corresponds to which optical system, eliminating ambiguity in zoom target selection.
Solution Approach 2:
The patent introduces an intermediary indicator (such as a frame or marker) that visually connects the zoom instruction to the specific live view image. This intermediary element mediates between the user's zoom command and the dual-image display, clearly indicating which image will be enlarged.
2Ease of operation
If the zoom target area is not clearly indicated, then the system maintains flexibility in zoom selection, but the user cannot visually identify which area will be enlarged
Solution Approach 1:
The system performs preliminary action by displaying a zoom frame or marker on the live view image before the actual zoom operation occurs. This advance indication allows users to visually confirm the zoom target area, providing clear feedback while maintaining a relatively simple display control mechanism.
Solution Approach 2:
The patent utilizes visual changes such as color differentiation or frame highlighting to indicate the zoom target area. By applying distinct visual markers to the selected live view image or zoom region, the system provides intuitive visual feedback without requiring complex display control mechanisms.

AI summary
Electronic equipment includes an obtaining unit configured to obtain a third image in which a first image captured via a first optical system and a second image captured via a second optical system are arranged side by side, the second image having parallax with the first image and a setting unit configured to set, in the third image, a target area to which predetermined processing is to be applied, based on a user operation. The setting unit is configured to set the target area in such a manner that the item indicating the target area includes either one of the first image and the second image.
