Image Frame Rate Adjustment for Visual Discontinuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reducing visual discontinuity in displaying image frames acquired at different imaging rates are limited in versatility and flexibility, primarily addressing the issue through preprocessing in imaging devices and only applicable to high-rate imaged frames.
Innovation Solution
An image processing device and method that determines which image frames to adjust the display rate for and adjusts the display rate within a predetermined period when the imaging rate switches, using techniques such as image frame thinning, thickening, parameter adjustment, and display timestamp adjustment to generate pseudo imaging rates that reduce visual discontinuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image frames are displayed at regular intervals without adjustment, then the display is simple and continuous, but visual discontinuity occurs at timing corresponding to switching of the imaging rate
Solution Approach 1:
The patent applies preliminary action by adjusting the displaying rate of image frames in advance within a predetermined period from the timing when the imaging rate is switched. The image frame determination unit identifies frames that need rate adjustment before display, and the displaying rate adjustment unit pre-adjusts their displaying rates to prevent visual discontinuity from occurring during playback.
2Adaptability or versatility
If the displaying rate adjustment method is limited to high-rate imaged frames only, then the processing is simpler, but the versatility and flexibility are reduced
Solution Approach 1:
The patent applies universality by enabling the displaying rate adjustment to work with image frames acquired at any different imaging rates, not only high-rate frames. The image frame determination unit determines frames for rate adjustment regardless of their original imaging rate, and the displaying rate adjustment unit adjusts them accordingly, making the system versatile and flexible for various imaging scenarios.

AI summary
The present disclosure relates to an image processing device, an image processing method, and a program capable of increasing the utility of processing for reducing discontinuity in display of image frames acquired through imaging at different imaging rates.From image frames including normally imaged frames imaged at a normal imaging rate, and high-rate imaged frames imaged at a rate higher than the normal imaging rate, determination is made on image frames imaged at at least one of the imaging rates to be image frames for which a displaying rate is to be changed. The displaying rate of the image frames determined to be the image frames for which the displaying rate is to be changed is adjusted within a predetermined range from a timing when the imaging rate is switched. The present technology is applicable to an image processing device configured to perform image processing on image frames, for example.
