1Speed

If images are thinned out during decoding to reduce processing load, then processing speed is improved, but execution accuracy of task processing deteriorates

Engineering Contradiction:

Improveprocessing speedVSAvoidexecution accuracy

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The encoding device performs preliminary analysis of image suitability for task processing before encoding, and embeds identification information in the bitstream. This allows the decoding device to quickly identify suitable images without performing complex analysis, thereby maintaining both high processing speed and high execution accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An identification flag or metadata is introduced as an intermediary element in the bitstream to indicate whether each image is suitable for task processing. This intermediary allows the system to filter images based on pre-encoded information, resolving the contradiction between processing speed and execution accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If all decoded images are used for task processing, then execution accuracy is improved, but processing load increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSPower

Solution Approach 1:

The encoding device extracts and embeds identification information indicating image suitability for task processing into the bitstream. The decoding device uses this extracted information to selectively process only suitable images, reducing processing load while maintaining execution accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Suitability analysis is performed in advance during encoding, and results are stored in the bitstream. This preliminary action eliminates the need for repeated analysis during decoding, reducing processing load while ensuring accurate selection of suitable images for task processing.

Inventive Principle:

Principle #10Preliminary action

AI summary

A decoding device includes: a circuit; and a memory connected to the circuit, in which the circuit decodes, from a bitstream, an image and an identifier associated with the image, and the identifier indicates at least one of a fact that the image is suitable for task processing corresponding to the identifier and a fact that the image is not suitable for the task processing.
