Frame Rate Conversion Level Adjustment for Display Judder Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame rate conversion (FRC) technologies in display devices do not allow users to set FRC levels according to their preferences, leading to varying perceptions of judder and halo effects, which affect the quality of motion in video playback.
Innovation Solution
A method and apparatus that allow users to input and set FRC levels, which adjust the motion estimation and motion compensation (ME/MC) levels, using graphical interfaces to select optimal settings for minimizing judder and halo effects, and provide test images for real-time feedback on FRC level adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If FRC level is increased to improve motion smoothness, then video smoothness is improved, but judder and halo effects become more severe
Solution Approach 1:
The patent implements dynamic adjustment of FRC levels based on user preference through a graphical interface. The system allows users to interactively set FRC levels by moving a cursor on a bar graph, and the ME/MC level is automatically adjusted according to the selected FRC level. This dynamic adjustment mechanism enables optimization between motion smoothness and artifact reduction based on individual user preferences.
Solution Approach 2:
The patent changes the FRC parameter (frame rate conversion level) and ME/MC parameter (motion estimation and compensation level) to resolve the contradiction. By adjusting these parameters through user input, the system can optimize the balance between motion smoothness improvement and artifact suppression. The controlling unit adjusts the ME/MC level according to the input FRC level to achieve optimal performance.
2Object-affected harmful factors
If FRC level is decreased to reduce judder and halo effects, then artifact severity is reduced, but motion smoothness deteriorates
Solution Approach 1:
The system provides dynamic control over FRC levels, allowing users to adjust the setting based on their tolerance for artifacts versus desire for motion smoothness. The graphical interface with movable cursor and bar graph enables real-time adjustment, and the controlling unit dynamically adjusts ME/MC levels according to the selected FRC level, optimizing the trade-off between artifact reduction and motion quality.
Solution Approach 2:
By adjusting the FRC parameter downward, the system reduces the severity of judder and halo effects. The patent implements parameter adjustment mechanisms where users can select lower FRC levels to minimize artifacts, and the ME/MC level is correspondingly adjusted to maintain optimal performance at the reduced FRC setting.
3Ease of operation
If automatic FRC setting is used to simplify operation, then ease of operation is improved, but adaptability to user preference deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where users can independently adjust FRC levels according to their own preferences through the graphical interface. The system provides tools (bar graph, movable cursor, direction keys) that enable users to perform the adjustment themselves without requiring automatic settings or external assistance, thus maintaining both ease of operation and user preference adaptability.
4Adaptability or versatility
If multiple FRC levels are provided to increase adaptability, then user preference adaptation is improved, but device complexity increases
Solution Approach 1:
The patent segments the FRC level selection into discrete, manageable options represented by a bar graph with intermediate portions indicating values between minimum and maximum. The graphical interface divides the adjustment range into visual segments that users can navigate using direction keys, making the complexity of multiple FRC levels manageable and intuitive rather than overwhelming.
Solution Approach 2:
The patent introduces a graphical interface as an intermediary between the user and the FRC level settings. The bar graph with movable cursor serves as a mediator that simplifies the interaction, allowing users to select from multiple FRC levels through intuitive visual feedback rather than dealing with raw numerical values or complex menus, thus reducing perceived device complexity.

AI summary
A method for setting a frame rate conversion (FRC) and a display apparatus using the same are provided. According to a method for setting FRC, an FRC level is received from a user; and a motion estimation and motion compensation level when performing FRC is set according to the input FRC level. Therefore, a user may set the FRC level according to the user's preference.
