Image Processing Device with Variable Shot Duration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image switching for broadcasting or delivery, maintaining viewer interest is challenging due to inconsistent timing of scene changes, as scenes that are too long or too short can cause discomfort, and automatic switching struggles to replicate the natural flow achieved by experienced operators.
Innovation Solution
An image processing device that selects a main image based on its classification and sets a variable continuous period length for each shot type, such as whole, main, and support shots, to control scene changes and maintain viewer engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic switching is performed with constant continuous period length for each shot, then the switching operation is simplified and automated, but the image content becomes less interesting and the flow appears unnatural
Solution Approach 1:
The patent applies dynamics by making the continuous period length variable rather than constant. The period setting unit dynamically adjusts the display duration of each shot based on its classification (whole shot, main shot, support shot), allowing the system to automatically adapt timing parameters to maintain natural flow while remaining fully automated.
Solution Approach 2:
The patent changes the parameter of continuous period length based on shot classification. Different parameter values are assigned to different shot types (e.g., whole shots have one duration, main shots have another), enabling the automatic switching system to produce natural-looking transitions by varying this key temporal parameter.
2Ease of operation
If the continuous period length of each shot is made variable according to image classification, then the image content flow becomes more natural and interesting, but the device complexity increases
Solution Approach 1:
The patent segments shots into distinct classifications (whole shot, main shot, support shot) with each having predetermined continuous period lengths. This segmentation approach simplifies the control mechanism by using discrete categories rather than continuous variable adjustment, reducing overall system complexity while achieving natural flow.
Solution Approach 2:
The patent performs preliminary action by pre-setting continuous period lengths for each shot classification before the switching occurs. The period setting unit establishes these timing parameters in advance based on shot type, eliminating the need for real-time complex calculations during switching operations.
3Reliability
If whole shots are displayed frequently to provide context, then viewer understanding of the scene is improved, but the continuous period without whole shot display should be limited to maintain engagement
Solution Approach 1:
The patent applies periodic action by implementing a monitoring mechanism that tracks the elapsed time since the last whole shot display. When the interval exceeds the predetermined second period length, the system is triggered to select and display a whole shot, ensuring regular contextual refreshes without over-displaying them.
Solution Approach 2:
The patent uses feedback by continuously monitoring the timing of whole shot displays and using this information to control future whole shot selections. The monitoring unit provides feedback about the current interval, and the switching control unit adjusts its behavior based on whether the predetermined time threshold has been exceeded.

AI summary
One image to serve as a main image is selected among a plurality of images and a continuous period length for which a selected image is continued as the main image is set in accordance with an image classification to which the selected image corresponds among a plurality of image classifications.
