Electronic Device Coordinate Mapping for Multi-Area Focus Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require users to consciously specify the image area for operations like AF and photometry, reducing usability as they need to differentiate between multiple image areas.
Innovation Solution
An electronic device that allows users to intuitively specify positions within a display image, automatically determining the appropriate image area for processing based on user coordinates, regardless of the actual image area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system restricts position specification to only one image area, then the processing complexity is reduced, but the usability is reduced because users need to be conscious of which image area they are specifying
Solution Approach 1:
The patent introduces a coordinate conversion mechanism as an intermediary that translates user specifications from the display image coordinate system to the appropriate optical system image area coordinate system. This mediator handles the complexity of determining which image area the user intends to specify and performs the necessary coordinate transformations, thereby maintaining simple user interaction while managing the underlying system complexity.
Solution Approach 2:
The patent creates a virtual copy of the coordinate system by establishing a correspondence relationship between the display image coordinates and the multiple optical system image area coordinates. This virtual coordinate copy allows users to specify positions intuitively on the displayed image while the system automatically maps these specifications to the correct physical image areas through pre-established coordinate relationships.
2Ease of operation
If the system supports position specification in multiple image areas, then the usability is improved, but the complexity of determining which image area to process increases
Solution Approach 1:
The patent performs preliminary actions by pre-establishing coordinate correspondence relationships between the display image and multiple optical system image areas before user interaction occurs. The system pre-calculates and stores the mapping relationships, so when a user specifies a position, the system can quickly determine the target image area without complex real-time analysis, thereby reducing the difficulty of image area identification.
Solution Approach 2:
The patent implements a feedback mechanism where the system receives the user's specified coordinates, automatically determines which image area corresponds to those coordinates through the pre-established relationships, and then executes the appropriate processing. This feedback loop allows the system to intelligently route user specifications to the correct image area without requiring users to manually identify or specify the image area.

AI summary
An electronic device acquires an image including a plurality of image areas captured via a plurality of optical systems, performs control so that a display image based on the acquired image is displayed, receives a user operation for specifying coordinates inside the display image, and performs control so that, when the coordinates inside the display image specified by the user operation correspond to coordinates inside a first image area among the plurality of image areas, predetermined processing is executed on a basis of the coordinates inside the first image area, and performs control so that, when the coordinates inside the display image specified by the user operation correspond to coordinates inside a second image area among the plurality of image areas, the predetermined processing is executed on a basis of coordinates inside the first image area corresponding to the coordinates inside the second image area.
