Display Control for Simultaneous Multi-Frame Rate Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital cameras face difficulties in determining the optimal frame rate for high frame rate images, as the image quality and slow motion impression are only noticeable after recording and viewing, requiring repeated adjustments to achieve desired results.
Innovation Solution
A display control device and method that simultaneously displays images at different frame rates on the same position in a display region, allowing users to intuitively compare image quality and adjust frame rates before recording, using flip switching and reference rate display control processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high frame rate imaging is used to achieve smooth movement or slow motion effect, then the movement smoothness is improved, but image quality deteriorates due to short exposure time
Solution Approach 1:
The patent applies preliminary action by displaying captured images at multiple different frame rates on the same position in the display region before the user finalizes their selection. This allows the user to preview and compare image quality and slow motion effects in advance, so they can determine the optimal frame rate beforehand without needing to repeat the imaging process multiple times.
Solution Approach 2:
The patent implements feedback by providing real-time visual comparison of images captured at different frame rates on the same display position. This feedback mechanism enables users to immediately see the differences in image quality and slow motion characteristics, helping them make informed decisions about the optimal frame rate to use for subsequent imaging.
2Speed
If high frame rate imaging is used to achieve smooth movement, then the movement smoothness is improved, but the amount of data for processing increases
Solution Approach 1:
The patent applies preliminary action by allowing users to preview images at multiple frame rates before finalizing their selection. This enables users to determine the highest acceptable frame rate that maintains adequate image quality, thereby avoiding unnecessary processing of excessively high frame rates that would generate excessive data without providing additional benefit.
3Adaptability or versatility
If frame rate is changed repeatedly to determine optimal setting, then the optimal frame rate can be found, but the operation becomes troublesome and time-consuming

AI summary
The present technology relates to a display control device, a display control method, and a program that make it possible to provide an interface useful for a user to easily determine an optimal frame rate. At least a first image and a second image that are at different frame rates or that have different image quality in frames at the same time are displayed on the same position in a display region of a display device. The present technology can be applied, for example, to a digital camera or the like that can image images at a plurality of frame rates.
