CODING APPARATUS AND METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18457441 titled 'CODING APPARATUS AND METHOD, AND STORAGE MEDIUM
Simplified Explanation
The patent application describes a coding apparatus that performs coding processing on each block of an input image. It includes a coding unit, an output unit, and a calculation unit.
- The coding unit executes coding processing using different prediction modes such as inter-prediction, intra-prediction, or multi-reference prediction.
- The output unit outputs the result of the coding processing as coded data.
- The calculation unit calculates a first coding cost if the block is coded in the inter-prediction mode and a second coding cost if the block is coded in the intra-prediction mode using a predetermined function.
- If the difference between the first coding cost and the second coding cost is equal to or less than a threshold, the coding unit executes the coding processing using the multi-reference prediction mode.
- If the difference is larger than the threshold, the coding unit uses the prediction mode with the smaller coding cost.
Potential applications of this technology:
- Video coding and compression systems
- Image processing applications
- Multimedia streaming and transmission
Problems solved by this technology:
- Efficient coding of image blocks
- Optimizing prediction modes for different blocks
- Reducing coding costs and improving compression efficiency
Benefits of this technology:
- Improved image and video compression
- Higher coding efficiency
- Reduced bandwidth requirements for multimedia transmission
Original Abstract Submitted
A coding apparatus that performs coding processing on each block of an input image comprises a coding unit that executes coding processing using an inter-prediction mode, an intra-prediction mode or a multi-reference prediction mode, an output unit that outputs a result of the coding processing as coded data; and a calculation unit that calculates a first coding cost if the block is coded in the inter-prediction mode and a second coding cost if the block is coded in the intra-prediction mode using a predetermined function. The coding unit executes the coding processing using the multi-reference prediction mode if a difference between the first coding cost and the second coding cost is equal to or less than a threshold, and using the prediction mode with a smaller one of the first coding cost and the second coding cost if the difference is larger than the threshold.
