Solution Overview
Problem
Existing display apparatuses cannot superpose guidance images on foodstuffs if they are outside the superposable area, limiting their ability to assist cooks, especially in space-constrained environments where moving the foodstuff or projector is not feasible.
Innovation Solution
A display apparatus that includes a display unit, an obtaining unit, a determination unit, and a display control unit to recognize foodstuffs, determine their position relative to the superposable area, and either superpose a guidance image directly on the foodstuff or on a secondary image generated from the foodstuff when it's outside the superposable area, allowing cooks to receive assistance regardless of the foodstuff's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display apparatus superposes the guidance image only on foodstuffs within the superposable area, then the display precision and clarity are improved, but the versatility and adaptability to different cooking scenarios deteriorate
Solution Approach 1:
The patent introduces a second image as an intermediary element between the guidance image and the actual foodstuff. When the foodstuff is outside the superposable area, the display apparatus superposes the guidance image on the second image (which represents the foodstuff) instead of directly on the foodstuff itself. This intermediary approach maintains display precision while extending adaptability to scenarios where direct superposition is not feasible.
2Manufacturing precision
If the superposable area is kept small to ensure clear guidance image display, then the display quality is improved, but the ease of operation and flexibility in foodstuff placement deteriorate
Solution Approach 1:
The patent extends the functional display area from the two-dimensional superposable area to include the third dimension of virtual space by introducing the second image. This allows the guidance image to be displayed in a location that maintains optimal display quality while accommodating foodstuffs placed in various positions on the cooking surface, effectively adding a virtual display layer that is not constrained by the physical superposable area boundaries.
3Measurement precision
If the display apparatus requires foodstuffs to be within the superposable area for guidance display, then the measurement precision of foodstuff location is improved, but the ease of operation and cooking workflow deteriorate
Solution Approach 1:
The patent creates a copy (second image) of the foodstuff that can be displayed in the superposable area even when the actual foodstuff is located outside this area. The recognition unit identifies the foodstuff anywhere in the photographable area, and the display control unit generates a representative second image that is then used as the target for superpositioning the guidance image. This copying mechanism maintains location detection precision while eliminating the constraint that would force cooks to move foodstuffs.

AI summary
A display apparatus includes: a display unit that displays a first image; an obtaining unit that obtains a recognition result of recognizing a foodstuff serving as a cooking target on the basis of a photographed image obtained from a camera; a determination unit that determines whether a recognized foodstuff indicated by the recognition result is present in a superposable area where the first image can be superposed on the foodstuff; and a display control unit that causes the display unit to: (i) superpose the first image on the foodstuff when the determination unit determines that the foodstuff is present in the superposable area; and (ii) superpose the first image on a second image when the determination unit determines that the foodstuff is not present in the superposable area.
