Display Control Apparatus HDR SDR Mode Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in determining whether an image is being displayed in HDR or SDR mode, leading to unintended adjustments during image adjustment work due to unawareness of the dynamic range differences, and existing techniques do not provide clear notification of HDR display status.
Innovation Solution
A display control apparatus and method that determines the dynamic range of an image and acquires setting information to notify users whether the image is being displayed in HDR or SDR mode, using a processor to control the display and optionally display an icon to indicate the mode, ensuring users are aware of the dynamic range for accurate adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If HDR images are displayed on display apparatuses without notification, then the display apparatus can maintain simple operation flow, but users cannot comprehend the dynamic range difference leading to unintended adjustments
Solution Approach 1:
The system provides feedback to users about the display mode (HDR or SDR) by displaying notification text on the screen. This feedback mechanism informs users of the dynamic range characteristics without requiring complex user input or interaction, resolving the contradiction by adding minimal complexity to convey essential information.
Solution Approach 2:
The notification text serves as an intermediary element between the HDR/SDR display system and the user. It translates the technical display mode into understandable information for users, bridging the gap between system capability and user awareness without requiring direct technical education.
2Manufacturing precision
If users perform image adjustment work without knowing the display mode, then workflow remains efficient, but adjustment accuracy deteriorates due to unawareness of dynamic range differences
Solution Approach 1:
The system performs preliminary action by displaying the notification text before users begin image adjustment work. This advance information provision allows users to understand the display mode in advance, enabling accurate adjustments from the start without requiring time-consuming corrections later.
Solution Approach 2:
The notification provides continuous feedback during the adjustment process, reminding users of the display mode characteristics. This feedback loop helps users maintain awareness of dynamic range differences throughout the workflow, preventing unintended adjustments and reducing iterative corrections.
3Ease of operation
If the system displays notification text to indicate HDR/SDR mode, then user awareness of dynamic range improves, but the display interface becomes more complex
Solution Approach 1:
The notification text is a simple, temporary display element that provides the necessary information and then disappears or remains static. It uses minimal interface resources (simple text overlay) rather than complex interactive components, achieving ease of operation with minimal added complexity.
Solution Approach 2:
The notification text can utilize color coding or visual differentiation to convey HDR/SDR mode information intuitively. By using color changes or distinct visual styles, the system communicates display mode information effectively without requiring complex text or interactive elements.

AI summary
A display control apparatus includes: a display control unit configured to perform control so as to display a target image; a determining unit configured to determine whether or not the target image is an image having a dynamic range that is wider than a predetermined range; an acquiring unit configured to acquires setting information related to whether or not a predetermined setting for displaying an image having a dynamic range that is wider than the predetermined range with a dynamic range that is wider than the predetermined range is valid; and a notification control unit configured to perform control such that, in a case where the target image is an image having a dynamic range that is wider than the predetermined range, a notification is performed with respect to whether or not the target image is being displayed with a dynamic range that is wider than the predetermined range.
