Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If higher resolution captured images are used, then image quality is improved, but data amount increases leading to insufficient storage capacity and communication bandwidth
Solution Approach 1:
The patent applies parameter changes by switching the coding scheme based on the moving body's state. When the moving body is stationary or moving slowly, still image coding is used. When the moving body is moving quickly, moving image coding is used. This dynamic parameter change optimizes the balance between image quality and data amount according to actual conditions.
Solution Approach 2:
The patent implements dynamics by making the coding scheme adaptive to the moving body's motion state. The system dynamically selects between still image coding and moving image coding based on real-time motion detection, allowing the coding efficiency to adapt to changing conditions and prevent excessive data generation.
2Ease of manufacture
If still image coding scheme is used for captured images, then coding simplicity is improved, but coding efficiency decreases when images are captured by a moving body
Solution Approach 1:
The system dynamically selects the coding scheme based on the moving body's motion state. When motion is detected, the system switches from still image coding to moving image coding, maintaining coding efficiency while preserving the simplicity of still image coding when appropriate.
Solution Approach 2:
The coding parameter (coding scheme type) is changed based on the motion state of the capturing device. This parameter change allows the system to optimize coding efficiency for moving bodies while maintaining the simplicity of still image coding when the body is stationary.
3Speed
If coded data is transmitted without transcoding, then transmission speed is improved, but storage capacity and communication bandwidth are insufficient
Solution Approach 1:
The patent changes the coding scheme parameter based on the moving body's state to optimize data amount. By selecting appropriate coding schemes (still image or moving image coding), the system reduces the total data amount that needs to be transmitted and stored, addressing the insufficiency of storage capacity and communication bandwidth.
Data Source
AI summary
There is provided an image processing apparatus and method allowing suppression of a decrease in coding efficiency. Coded data obtained by coding a captured image captured by a moving body with an image capturing section is transcoded on the basis of positional information indicating a position where the captured image has been generated. For example, the positional information includes at least one of GPS information indicating the position of the moving body or IMU information indicating movement of the moving body, and captured images are coded in frame images of a moving image on the basis of the information. For example, the present disclosure can be applied to an image processing apparatus, an image coding apparatus, a communication apparatus, an information processing apparatus, an image capturing apparatus, or the like.
