Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies face challenges in maintaining high-frequency data acquisition for effective correction processing, particularly in video production, leading to unnatural combinations of live-action and computer graphics due to inefficient communication cycles and reduced data acquisition frequencies.
Innovation Solution
An image pickup apparatus and lens apparatus with a communication unit and processor that prioritize data transmission based on predetermined conditions, ensuring high-frequency communication of critical correction data for alignment and quality adjustments, such as position and brightness changes, to enhance the integration of live-action and computer-generated imagery.

Engineering Contradiction Analysis
1Loss of time
If data communication cycle is extended to reduce communication frequency, then communication processing time is reduced, but data acquisition frequency decreases and high-frequency correction processing becomes unavailable
Solution Approach 1:
The patent segments correction data into different priority levels (first priority and second priority data). First priority data (position coordinates) is transmitted at high frequency, while second priority data (brightness and color shift) is transmitted at lower frequency. This segmentation allows the system to maintain high data acquisition frequency for critical parameters while reducing overall communication processing time.
Solution Approach 2:
The patent applies different communication strategies to different types of correction data based on their local importance. Position coordinate data receives high-frequency communication treatment, while brightness and color shift data receive reduced-frequency treatment. This local differentiation optimizes the balance between communication time and data acquisition frequency for each data type.
2Measurement precision
If all correction data is transmitted at high frequency, then correction processing accuracy is improved, but communication processing time increases
Solution Approach 1:
The patent divides correction data into segments based on importance: first priority data (position coordinates requiring high accuracy) and second priority data (brightness and color shift). This segmentation enables high-frequency transmission for critical position data to maintain accuracy, while reducing frequency for less critical data to control processing time.
Solution Approach 2:
The patent changes the communication frequency parameter dynamically based on data priority. High frequency is applied to first priority data, while reduced frequency is applied to second priority data. This parameter adjustment optimizes the balance between correction accuracy and processing time.
