Information Processing Apparatus Automatic Frame Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face a heavy burden in selecting desired frame images from large numbers of frames in a movie, as existing technologies lack efficient user interfaces for clipping frame images from movies, making it difficult to capture decisive moments without being sensitive to shutter opportunities.
Innovation Solution
An information processing apparatus with a display, operation receiver, and controller that displays a selection screen showing candidate images with manual and automatic marker information, allowing users to easily select frame images by moving the frame position based on user-marked or automatically detected features, thereby simplifying the selection process.

Engineering Contradiction Analysis
1Measurement precision
If a user manually selects a frame image from a movie to generate a still image, then the user can capture decisive moments, but the user faces a heavy burden due to the large number of frame images (e.g., 600 frames at 60 fps for 10 seconds)
Solution Approach 1:
The system performs automatic marking of frame images based on detection results (e.g., face detection, object detection) without requiring manual user intervention for each frame. The controller automatically identifies and marks candidate frames, allowing the system to serve itself in the selection process rather than requiring the user to manually evaluate each of the 600+ frames
Solution Approach 2:
The patent replaces the mechanical/manual process of frame-by-frame selection with an automated detection and marking system. Instead of the user manually scrolling through and selecting frames, the system uses automated image analysis to detect and mark candidate frames, substituting manual mechanical selection with automated computational analysis
2Adaptability or versatility
If the system displays all frame images for user selection, then the user can choose the desired frame, but the user interface becomes complex and time-consuming to navigate through large numbers of frames
Solution Approach 1:
The system extracts only the candidate frame images that meet specific detection criteria (e.g., frames containing faces, objects, or specific features) and marks them for user selection. Instead of presenting all 600+ frames to the user, the system extracts and highlights only the relevant candidate frames, significantly reducing the number of frames the user needs to review while maintaining selection flexibility
Solution Approach 2:
The system performs preliminary automatic marking of candidate frames before presenting them to the user for selection. By pre-identifying and marking candidate frames based on detection results, the system prepares the selection interface in advance, so when the user views the frames, the candidate frames are already highlighted and ready for selection, reducing the time and complexity of the selection process

AI summary
An information processing apparatus includes a display, an operation receiver, a storage, and a controller. The operation receiver receives an instruction indicating a switch of a candidate image from a user. The storage stores movie data. The controller controls the display to display a selection screen via which a frame image to be stored as a still image is selected from the movie data. The selection screen includes the candidate image, first marker information, and second marker information. The controller moves a frame position of the candidate image based on the position indicated by the first marker information or the second marker information in a case where the operation receiver receives the instruction.
