Image Capturing Apparatus Composition Guide via Superimposed Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photographers face difficulties in smoothly changing shooting compositions during telephoto shooting, as they need to search for each composition from a wide-angle image each time the composition is switched, leading to missed opportunities.
Innovation Solution
An image capturing apparatus with sensors and a control unit that displays a shooting frame indicating the area where the wide-angle and telephoto images coincide, allowing for easier composition changes by superimposing zooming target frames on the live view image, facilitating the transition between focal lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a photographer uses a wide-angle image to search for telephoto shooting compositions, then the overall scene can be grasped, but the time required for composition changes increases and shooting opportunities may be missed
Solution Approach 1:
The patent creates a virtual copy of the telephoto shooting composition by displaying a frame indicating the telephoto angle of view on the wide-angle live view image. This virtual frame serves as a guide that allows the photographer to see where the telephoto shot will be framed without actually switching to telephoto mode, thereby reducing the time for composition changes and preventing missed shooting opportunities
Solution Approach 2:
The patent introduces an intermediary visual element (the frame indicating telephoto angle of view) that mediates between the wide-angle and telephoto viewing modes. This frame acts as a bridge, allowing the photographer to plan telephoto compositions while viewing the wide-angle scene, eliminating the need to repeatedly switch between viewing modes
2Measurement precision
If the photographer switches between wide-angle and telephoto views to determine composition, then accurate framing is achieved, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent segments the viewing information by superimposing the telephoto angle of view frame on the wide-angle live view image. This allows the photographer to simultaneously see both the wide-angle context and the telephoto framing guide in a single unified display, eliminating the need to switch between separate viewing modes and simplifying the composition process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the time required for composition changes and minimizes the likelihood of missing shooting opportunities by providing a clear guide for telephoto shooting compositions within the wide-angle image.
Implementation Method 1
a sensor that performs photoelectric conversion on light formed by an optical system and outputs image data
Data Source
AI summary
An apparatus having a sensor that performs photoelectric conversion on light formed by an optical system and outputs a resultant image, stores in memory a first image output from the sensor in a state that the optical system is controlled to a first focal length, and displays, on a second image output from the sensor in a state that the optical system is controlled to a second focal length which is shorter than the first focal length, a shooting frame indicating an area in which the second image and the first image coincide.
