Composite Image Generation for Moving-Image Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies fail to effectively maintain viewer interest in moving images by not providing sufficient detail about the central subject, leading to disengagement over long playback times.
Innovation Solution
An image processing apparatus that calculates transformation information between successive frames of a moving image, allowing for the transformation and combination of history and current images to generate composite images, which are then sequentially output to enhance viewer understanding and engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video indices (still images) are displayed alongside a moving image to maintain viewer interest, then viewer engagement is improved, but the displayed still images may be substantially the same as the current moving image, reducing their effectiveness
Solution Approach 1:
The patent segments the moving image into multiple still images at different time points and selectively displays them as video indices. By dividing the continuous moving image into discrete temporal segments, the system can choose representative still images that show different scenes or subjects, ensuring diversity in the displayed indices rather than showing redundant frames.
Solution Approach 2:
The patent performs preliminary analysis of the moving image to identify and extract key still images that represent different scenes or subjects before display. By pre-processing the moving image to detect scene changes or subject transitions, the system prepares a set of diverse still images in advance, ensuring that the displayed video indices provide meaningful variety and detail about different aspects of the moving image content.
2Loss of information
If the same moving image is played for a long duration to provide complete information, then information completeness is improved, but viewer interest decreases over time
Solution Approach 1:
The patent implements periodic updates of the displayed video indices during moving image playback. By periodically refreshing the still images shown alongside the moving image, the system maintains viewer interest through varied visual content while continuing to provide access to complete information about the moving image through the sequence of displayed indices.
Solution Approach 2:
The patent uses viewer interaction feedback to dynamically adjust which still images are displayed as video indices. By monitoring viewer preferences or attention patterns, the system can adaptively select and display still images that are most relevant or interesting to the current viewer, maintaining engagement while preserving information completeness through selective presentation.
3Measurement precision
If transformation information is calculated between successive frames to generate composite images, then image detail and understanding are improved, but processing complexity increases
Solution Approach 1:
The patent applies transformation information calculation selectively to specific regions or key areas of the moving image rather than processing the entire image uniformly. By focusing computational resources on locally important regions that contain significant visual information or subject matter, the system achieves high image detail accuracy in critical areas while reducing overall processing complexity.
Solution Approach 2:
The patent dynamically adjusts the level of transformation information calculation based on image content characteristics. By changing processing parameters such as transformation accuracy, resolution, or computational intensity according to the complexity or importance of different image regions, the system optimizes the balance between image detail accuracy and processing complexity, applying high precision only where necessary.

AI summary
To allow a viewer to easily understand the details of a moving image shot by an image capturing apparatus in the case where the moving image is browsed. A camerawork detecting unit 120 detects the amount of movement of an image capturing apparatus at the time of shooting a moving image input from a moving-image input unit 110, and, on the basis of the amount of movement of the image capturing apparatus, calculates affine transformation parameters for transforming an image on a frame-by-frame basis. An image transforming unit 160 performs an affine transformation of at least one of the captured image and a history image held in an image memory 170, on the basis of the calculated affine transformation parameters. An image combining unit 180 combines, on a frame-by-frame basis, the captured image and the history image, at least one of which has been transformed, and causes the image memory 170 to hold a composite image. The composite image generated by the image combining unit 180 is displayed on a display unit 191.
