Image Processing Controller Selective Chapter Writing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capture devices do not effectively generate a favorable digest movie by selectively writing movie data based on shooting conditions, leading to inclusion of inappropriate chapters.
Innovation Solution
An image processing apparatus with a controller that determines, based on shooting conditions, whether to write movie data as chapters on a storage medium, excluding inappropriate data by calculating evaluation values for save decision conditions and applying weighting coefficients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all movie data is written to storage medium without selection, then no data is lost, but the digest movie quality deteriorates due to inclusion of inappropriate chapters
Solution Approach 1:
The patent extracts and removes inappropriate chapters from the movie data based on evaluation of shooting conditions. The controller calculates evaluation values for each chapter using weighting coefficients for different shooting conditions, and selectively excludes chapters that do not meet quality criteria, thereby improving digest movie quality while maintaining data completeness for appropriate chapters.
2Manufacturing precision
If selective writing based on shooting conditions is implemented, then digest movie quality improves, but device complexity increases
Solution Approach 1:
The patent changes parameters by introducing evaluation values and weighting coefficients that quantify different shooting conditions. The controller uses these parameters to automatically determine which chapters to include or exclude, transforming a complex qualitative judgment process into a systematic parameter-based decision mechanism that improves digest movie quality without excessive complexity increase.
3Measurement precision
If evaluation values and weighting coefficients are calculated for each chapter, then chapter selection accuracy improves, but processing time increases
Solution Approach 1:
The patent performs preliminary evaluation of shooting conditions and calculates evaluation values for each chapter during or immediately after the shooting session. By preparing these evaluation metrics in advance, the system enables rapid chapter selection and exclusion decisions, improving selection accuracy while minimizing the time loss that would occur if evaluation had to be performed after all processing was complete.

AI summary
An image processor according to an embodiment of the present disclosure includes a movie generating section which generates movie data based on an image capturing signal that has been generated by an image capturing section, and a controller which determines, by reference to information concerning a shooting condition, whether or not to write the movie data (chapter(s) just before and/or right after a still picture is shot) on a memory in accordance with a shooting instruction.
