Digital Camera Preview Position Cues for Multi-Image Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital cameras do not effectively allow users to recognize the position of captured images within a set of multiple images recorded in one frame, nor do they facilitate composition consideration based on these positions.
Innovation Solution
A digital camera with an imaging element, image recording unit, and image display unit, equipped with a processor that displays a preview image and notifies users of the disposition position of images within a set, allowing easy recognition and composition consideration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple images are recorded in one frame to reduce the number of frames, then the quantity of recorded images increases, but the user cannot easily recognize the disposition position of each image in the set
Solution Approach 1:
The patent uses different color representations (e.g., grayscale vs. color) to indicate the disposition position of images. By changing the visual attribute (color) based on the position information, the system effectively communicates spatial arrangement without requiring additional textual labels or complex display formats.
Solution Approach 2:
The patent introduces an intermediary visual element (such as a position indicator or coded representation) that mediates between the raw image data and the user's perception. This intermediary layer translates the disposition position information into a visually intuitive form, enabling users to easily recognize where each image is located within the frame.
2Ease of manufacture
If film camera techniques are used to record multiple images, then the manufacturing process is simple, but the user cannot check composition and disposition position simultaneously
Solution Approach 1:
The patent replaces the mechanical film-based recording system with a digital imaging system that uses an imaging element (sensor) to capture multiple images. This substitution enables electronic processing and display of disposition position information, allowing users to simultaneously view both the image content and its spatial arrangement without the limitations of physical film handling.
Solution Approach 2:
The patent adds a new dimension of information display by superimposing disposition position indicators onto the image display. Instead of only showing the image content, the system combines visual information with spatial metadata in a multi-dimensional display format, enabling users to perceive both composition and position simultaneously.
3Device complexity
If only half-screen capture mode is implemented, then the device complexity is low, but the adaptability to record three or more images in one frame is limited
Solution Approach 1:
The patent implements a dynamic capture mode that can adapt between different numbers of images per frame (e.g., one image, two images, or three or more images). Instead of being fixed to a single half-screen mode, the system can dynamically adjust the frame structure based on the number of captured images, providing versatility while maintaining relatively simple underlying mechanisms.
Solution Approach 2:
The patent creates a universal recording mechanism that can handle multiple capture scenarios (single image, dual image, or multi-image frames) within a single system framework. This multi-functional design allows the same basic imaging hardware to serve various purposes without requiring separate specialized mechanisms for each capture mode.
Data Source
AI summary
A digital camera includes an imaging element that images an object, a card I/F and a memory card that record an image acquired by the imaging element, a display that displays a preview image which has not yet been recorded in the memory card, and a controller. The controller displays the preview image on the display and notifies a user of information related to a disposition position of the preview image in a case where the preview image is treated as one of a plurality of images that are recorded and included in one set.
