Dynamic Guide Frame Display for Aspect Ratio Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video cameras with image display sections of aspect ratio 16:9 struggle to accurately record still images of aspect ratio 4:3, as the displayed image does not coincide with the recording region, leading to user confusion and increased chances of missed image pickup opportunities due to cumbersome mode switching between 16:9 and 4:3 aspect ratios.
Innovation Solution
An image pickup apparatus with a dynamic guide frame display system that adjusts based on recording mode settings, displaying distinct guide frames for moving and still images on the display section, only showing frames for recording-capable media, allowing users to accurately identify and record image regions without mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a video camera with image display section of aspect ratio 16:9 is used to record still images of aspect ratio 4:3, then the display section can show wide images, but the displayed image does not coincide with the recording region, causing user confusion
Solution Approach 1:
The patent introduces a guide frame as an intermediary visual element that mediates between the 16:9 display section and the 4:3 recording region. The guide frame overlays the displayed image to clearly demarcate the actual recording boundaries, allowing users to understand which portion of the displayed image will be captured. This intermediary visual cue resolves the mismatch between display and recording aspects without requiring mode switching.
2Measurement precision
If mode switching between 16:9 and 4:3 aspect ratios is implemented, then accurate recording region display is achieved, but operation becomes cumbersome and image pickup opportunities may be lost
Solution Approach 1:
The patent implements a dynamic guide frame display system that automatically adapts to the current recording mode (still image or moving image) and aspect ratio settings. The control unit dynamically generates and displays appropriate guide frames without requiring manual mode switching by the user. The system dynamically adjusts the guide frame parameters based on the selected recording conditions, maintaining measurement precision while eliminating operational complexity.
3Loss of information
If guide frame is displayed for both moving and still images simultaneously, then complete information is provided, but display section becomes cluttered and confusing
Solution Approach 1:
The patent segments the guide frame display into distinct modes for moving images and still images. The control unit determines which type of guide frame to display based on the current recording mode selection. When still image recording is selected, only the still image guide frame is displayed; when moving image recording is selected, only the moving image guide frame is displayed. This segmentation prevents information overload while ensuring complete and accurate recording region information is provided for the active recording mode.
Data Source
AI summary
An apparatus and method is disclosed which allows a user to grasp recording image regions for a moving image and a still image to be recorded actually to perform accurate image recording. An image pickup apparatus which can record moving images and still images determines forms of guide frames for a moving image and a still image based on aspect ratios for moving images and still images set in advance by a user. The guide frames are displayed on a monitor screen in response to a situation of an actual recording process. Where the image pickup apparatus is not in a state wherein image data can be recorded such as where a medium does not exist, only a guide frame for an image of a category which can be recorded is displayed together with a picked up image.
