Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals with image sensors require large buffer memory and take a long time to process image data, making them inconvenient for users.
Innovation Solution
An apparatus and method that processes image data by converting and storing it in a plural buffer memory with multiple storage areas, allowing sequential reading and encoding, reducing the need for large memory capacity and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional entire frame processing is used, then complete image data is processed, but large buffer memory is required and processing time increases
Solution Approach 1:
The patent divides the image processing task into two segments: first processing partial lines of the frame to generate preview data, then processing the remaining lines. This segmentation allows the buffer memory to store only the partial line data needed for preview generation rather than the entire frame data, significantly reducing buffer memory requirements while maintaining processing functionality.
Solution Approach 2:
The patent applies partial action by processing only a subset of the image data (partial lines) rather than the complete frame. This partial processing generates sufficient preview data for display purposes without requiring the computational resources and memory capacity needed for full frame processing, thus improving processing speed while reducing buffer memory size.
2Loss of time
If entire frame processing is performed, then complete image quality is maintained, but processing time increases
Solution Approach 1:
The patent processes only partial lines of the image frame rather than the entire frame, which significantly reduces processing time. This partial processing approach generates adequate preview quality data for real-time display without requiring the time-consuming complete frame processing, thus resolving the contradiction between processing time and productivity.
Solution Approach 2:
By segmenting the processing task to handle only partial lines first, the patent enables faster preview generation. The segmented approach allows the system to display preview data quickly while optionally processing remaining lines in the background, thereby improving processing speed without completely sacrificing image quality.
Data Source
AI summary
An apparatus and method for processing image data are provided. Using the method of the present invention, image data output from an image sensor can be rapidly processes and the necessary amount of buffer memory can be reduced. To this end, first image data of one frame is processed and converted into second image data in an image sensor part. The converted second image data is stored in a plural buffer memory having a plurality of storage areas. The second image data is sequentially read from the plural buffer memory, and then encoded.
