Adjusting OSD Position Based on Main Image Zoom Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common projectors face issues where OSD images are not effectively displayed within the main image area, leading to inefficient use of the display area, especially when the main image is reduced in size, causing the OSD image to be positioned apart or only partially visible.
Innovation Solution
A display device and system that include a zoom ratio determining unit and a position adjusting unit to adjust the display position of OSD images based on the zoom ratio of the main image, ensuring the OSD image is accommodated within the main image area, even when the main image is resized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the size of the main image is reduced while maintaining the size of the OSD image, then the OSD image remains readable, but the OSD image is displayed at a position apart from the main image, causing ineffective use of the display area
Solution Approach 1:
The patent applies dynamics by making the OSD image size adjustable rather than fixed. The control unit dynamically changes the OSD image size based on the zoom ratio of the main image, allowing the system to adapt to different display conditions while maintaining both readability and effective display area utilization.
Solution Approach 2:
The patent changes the size parameter of the OSD image in response to changes in the zoom ratio parameter of the main image. When the zoom ratio changes, the control unit automatically adjusts the OSD image size to maintain appropriate proportions and positioning, resolving the contradiction between readability and display area efficiency.
2Area of stationary object
If the size of the main image is reduced in accordance with the display area of the projector, then the main image fits the display area, but only a part of the OSD image is displayed within the display area, hindering effective use of the display area
Solution Approach 1:
The system dynamically adjusts the OSD image size based on the zoom ratio to ensure the complete OSD image remains within the display area. The control unit calculates the appropriate OSD size that prevents any part of the OSD image from being cut off while maximizing display area utilization.
Solution Approach 2:
The control unit proactively adjusts the OSD image size before display based on the determined zoom ratio, ensuring that the entire OSD image will fit within the display area. This preliminary adjustment prevents information loss by calculating the optimal size in advance.
3Measurement precision
If the OSD image size is not reduced when the main image size is reduced, then the OSD image remains readable, but the display position becomes separated from the main image
Solution Approach 1:
The patent changes the OSD image size parameter in response to changes in the main image zoom ratio. The control unit automatically adjusts the OSD size to maintain appropriate visual integration with the main image while preserving readability through proportional scaling.

AI summary
An object of the present disclosure is to effectively use a display area. In one embodiment of the present disclosure, a display device includes a zoom ratio determining unit configured to determine whether a zoom ratio is set for a first image to be displayed in accordance with first image data that has been input into the display device, and a position adjusting unit configured to adjust a display position of a second image that indicates information on the display device in accordance with the zoom ratio of the first image, in response to the zoom ratio determining unit having determined that the zoom ratio is set.
