Accessory Information Recording in Moving Image Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for recording accessory information in moving image data increase processing load and storage capacity, especially when applied to multiple frames, due to the need to search and record similar information across frames.
Innovation Solution
A recording method that recognizes subjects in frames, searches for and records accessory information efficiently by restricting the search and recording steps based on similarity between frames, using a processor to execute recognition, search, and recording processes, and storing accessory information in a separate data file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If accessory information is recorded for each frame of moving image data, then the completeness of accessory information is improved, but the processing load and storage capacity are increased
Solution Approach 1:
The patent applies partial action by executing the search step for only a subset of frames rather than all frames. Specifically, the search step is executed for frames where subjects are recognized, while frames with similar subjects (determined by similarity determination) skip the search step. This partial execution reduces processing load while maintaining sufficient accessory information completeness.
2Loss of information
If accessory information is recorded for each frame of moving image data, then the completeness of accessory information is improved, but the storage capacity is increased
Solution Approach 1:
The patent reduces storage capacity requirements by applying partial action - recording accessory information only for frames where the search step is executed, rather than for all frames. Frames with similar subjects that skip the search step also skip the recording step, thereby reducing the total quantity of stored accessory information while maintaining information completeness for distinctive subjects.
3Measurement precision
If the search step is executed for all frames, then the accuracy of accessory information is improved, but the processing time is increased
Solution Approach 1:
The patent applies partial action by selectively executing the search step only for frames where subjects are recognized and where similarity determination indicates the frame is sufficiently different from previous frames. This partial execution significantly reduces processing time compared to executing the search step for all frames, while maintaining accuracy for frames that require it.
Solution Approach 2:
The patent applies preliminary action through the similarity determination step, which is executed before the search step to predict whether the search step will be necessary. This preliminary assessment allows the system to skip unnecessary search operations, reducing processing time while ensuring accuracy is maintained for frames that genuinely require accessory information search.
4Productivity
If similarity determination is performed between frames, then the processing efficiency is improved, but the device complexity is increased
Solution Approach 1:
The patent introduces an intermediary element - the similarity determination unit - that acts as a mediator between subject recognition and the search step. This intermediary assesses whether frames are sufficiently different to warrant executing the search step, thereby improving processing efficiency by avoiding redundant searches while adding a manageable layer of complexity through a dedicated determination mechanism.

AI summary
There are provided a recording method, a recording device, and a program for efficiently recording accessory information in a frame of moving image data.There is provided a recording method of recording accessory information in a frame of moving image data including a plurality of frames, the recording method including: a recognition step of recognizing a subject in the frame for each of the frames; a search step of searching for the accessory information that is able to be recorded for the recognized subject among pieces of the accessory information; and a recording step of recording the accessory information in the frame based on a result of the search step, in which, in a case where the number of the frames included in the moving image data is set as a first number and the number of the frames in which the search step is executed is set as a second number, the second number is smaller than the first number.
