Composition Guidance via Auditory and Visual Feedback in Digital Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital image processing devices, such as cameras and camcorders, rely solely on visual information for photographing, leading to user inconvenience during self-photographing as users cannot see the LCD screen and struggle to achieve a desired composition, resulting in repeated attempts to capture a desired picture.
Innovation Solution
A method and apparatus that utilize auditory and visual alerts to guide users in adjusting the composition of a target object to match a predetermined reference composition, using a detection unit to analyze the object's size, position, and direction, and outputting auditory or visual signals to adjust the zoom, flickering speed, and color of a light to assist in aligning the object with the reference composition, allowing for automatic capture after a predetermined time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual information only is used for photographing, then the device structure remains simple, but the user cannot obtain desired composition during self-photographing
Solution Approach 1:
The patent implements feedback by providing real-time auditory and visual information about the current composition of the target object compared to the reference composition. The detection unit continuously monitors the live-view image and provides feedback signals to guide the user in adjusting the composition until it matches the reference composition, enabling accurate self-photographing without requiring the user to visually check the LCD screen.
Solution Approach 2:
The patent introduces auditory information as an intermediary to bridge the gap between the user and the composition information. Instead of requiring direct visual contact with the LCD screen, the system uses auditory signals (speakers) to convey composition status, allowing users to achieve desired composition during self-photographing without seeing the display.
2Reliability
If the user repeatedly attempts to capture a desired picture, then the chance of obtaining the desired composition increases, but the time consumption increases
Solution Approach 1:
The real-time feedback mechanism allows users to know immediately whether the current composition matches the reference composition, eliminating the need for repeated trial-and-error photographing. The detection unit provides continuous composition information, enabling users to adjust the framing once and capture the desired picture on the first attempt, significantly reducing time consumption while maintaining high reliability.
Solution Approach 2:
The system performs preliminary composition verification before the actual photographing action. By detecting and comparing the composition in advance and providing feedback, the system ensures that the composition is correct before the user triggers the shutter, preventing wasted time on incorrect shots and ensuring high reliability of the captured image.
3Ease of operation
If auditory information is added to visual information, then the composition guidance is improved, but the device complexity increases
Solution Approach 1:
The patent uses auditory information as an intermediary channel to convey composition guidance, complementing the visual live-view display. The detection unit processes image data and translates composition status into auditory signals that guide the user, improving ease of operation particularly for self-photographing scenarios where visual feedback is limited, while adding only moderate complexity through standard audio output components.

AI summary
Provided is a method and apparatus for providing composition information in a digital image processing device whereby composition information of a target object displayed in a live-view screen is provided using auditory information or visual information during photographing in order to induce a composition of the target object to be matched to a predetermined composition for photographing. The apparatus includes a detection unit detecting a composition of an object from a live-view image to be captured, a comparison unit comparing the detected composition with a reference composition, and a control unit performing a control operation to output an auditory alert signal until the detected composition is matched to the reference composition and performing a control operation to output an auditory match signal when the detected composition is matched to the reference composition.
