Display Guide Image for Calibrator Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses face challenges in achieving uniformity due to spatial non-uniformity issues, where brightness and color characteristics vary, making it difficult to perform accurate non-uniformity correction, especially when calibrators get caught on bezels or require multiple rotations for precise measurements.
Innovation Solution
A display apparatus that displays a guide image to assist in positioning the calibrator, divided into areas for calibration, with guide images that rotate and disappear as needed to ensure accurate calibration, improving user convenience and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the calibrator is placed in the center of the pertinent local area by eye measurement, then the calibration process can be performed, but the measurement precision deteriorates because the sensor may not be placed exactly where intended
Solution Approach 1:
A guide image is introduced as an intermediary visual element between the calibration target area and the calibrator placement. The guide image displays the exact position and orientation where the calibrator should be placed, serving as a mediator that translates the abstract concept of 'center position' into concrete visual guidance, thereby improving both ease of operation and measurement precision
Solution Approach 2:
The manual eye measurement and physical positioning method is replaced with a visual display system. Instead of relying on human visual estimation and manual adjustment, the system uses a display unit to present guide images that automatically indicate the correct calibrator position, substituting mechanical positioning with optical information presentation
2Measurement precision
If the calibrator is rotated multiple times to achieve exact measurement in edge and corner areas, then measurement precision improves, but the time required for calibration increases
Solution Approach 1:
The guide image is displayed in advance to indicate the correct orientation and position of the calibrator before the user places it. By providing preliminary visual information about the required calibrator orientation, the system eliminates the need for multiple rotation attempts, thereby maintaining measurement precision while reducing calibration time
Solution Approach 2:
The guide image provides immediate visual feedback to the user about the correct calibrator placement. This feedback mechanism allows the user to understand the required orientation and position without trial and error, reducing the iterative process of rotation and remeasurement that would otherwise be necessary to achieve precise edge and corner measurements
3Ease of operation
If the calibrator gets caught on the bezel of the display screen, then the calibration cannot be performed, but rotating the calibrator 180° requires additional time and complexity
Solution Approach 1:
The guide image acts as an intermediary that provides visual information about the correct calibrator placement orientation. By displaying the guide image that shows the proper alignment, the user can place the calibrator correctly on the first attempt without encountering bezel interference, eliminating the need for time-consuming rotation and repositioning operations

AI summary
A display apparatus is disclosed. The display apparatus includes a display unit which displays a calibration screen divided into a plurality of areas when a calibration mode is initiated, an image generating unit which generates a guide image for displaying an arrangement position of a calibrator, and a controlling unit which controls the display unit to display a guide image on areas where calibration is to be performed of the plurality of areas. Accordingly, it becomes possible to improve user convenience and exactness of calibration.
