Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high processing capability circuit is installed to achieve real-time development of RAW images, then the development speed and image quality are improved, but the power consumption and cost increase
Solution Approach 1:
The development process is divided into two distinct modes: a simplified development mode for real-time processing during capturing, and a high-quality development mode for post-processing. This segmentation allows the system to use different processing capabilities appropriate to each stage, avoiding the need for continuous high-power processing.
Solution Approach 2:
The system dynamically switches between simplified and high-quality development modes based on the processing stage. During capturing, the simplified mode is used for real-time preview; after capturing, the high-quality mode is applied for final processing. This dynamic adaptation optimizes power consumption while maintaining development quality where needed.
2Adaptability or versatility
If RAW images are recorded without development, then the flexibility for post-editing is improved, but the data amount and buffer requirements increase
Solution Approach 1:
The system performs preliminary simplified development during the capturing process to generate preview images for real-time display. This preliminary action reduces the data amount that needs to be buffered and processed later, while the original RAW data is preserved for post-processing flexibility.
3Manufacturing precision
If development parameters are made configurable for users, then the image quality and user customization are improved, but the complexity of parameter setting increases
Solution Approach 1:
Different development parameters are applied to different development stages and modes. The simplified development mode uses optimized default parameters for real-time processing, while the high-quality mode allows for configurable parameters in post-processing. This localized parameter application maintains ease of operation during capturing while enabling quality optimization later.
Data Source
AI summary
During capturing, image data obtained by applying a simplified development process to RAW image data is recorded together with a RAW image. Afterward, image data obtained by applying a high quality development process to the RAW image data is generated, and this image data replaces the image data obtained by the simplified development. During capturing, a plurality of pieces of image data are generated by using a plurality of different development parameters for RAW image data, and recorded in association with the RAW image data. The development parameter corresponding to image data selected by the user is decided as a development parameter used for the subsequent high quality development process for the RAW image data, thereby facilitating the setting of the development parameters of the RAW image.
