Image Processing Apparatus Dynamic Display Region for Scene Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Changing playback speed during magnified display of a moving image makes it difficult to understand the content, especially when the angle of view is narrow and playback speed is increased for scene search.
Innovation Solution
An image processing apparatus and method that adjusts the display region in accordance with the changed playback speed, where faster playback speeds result in larger display regions, ensuring that the content remains easily identifiable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the playback speed is increased for scene search, then the productivity is improved, but the content identification becomes difficult due to narrow angle of view
Solution Approach 1:
The display region is dynamically adjusted based on playback speed. When playback speed increases, the display region automatically expands to show a wider angle of view. This dynamic adaptation allows fast-forward playback to maintain both efficiency and content identifiability by correlating display parameters with playback state.
Solution Approach 2:
The patent changes the display region parameter in response to playback speed changes. Specifically, when playback speed increases, the display region parameter is modified to expand the visible area, thereby maintaining content identification capability while enabling faster scene searching.
2Manufacturing precision
If the display region is kept narrow for magnified display, then the manufacturing precision is improved, but the content identification becomes difficult when playback speed changes
Solution Approach 1:
The system transitions from a static narrow display region to a dynamic display region that adapts to playback speed. During normal playback, the display region remains narrow for high-quality magnified view. During fast-forward, it dynamically expands to facilitate scene search, thus resolving the contradiction between precision and ease of operation.
Solution Approach 2:
The display region parameter is changed based on playback speed conditions. When playback speed exceeds a threshold, the system modifies the display region parameter to expand the visible area, allowing content identification during fast-forward while maintaining narrow display for normal playback quality.

AI summary
An image processing apparatus includes a control unit to control operation, when displaying an image out of a series of images on a display device, so as to cut out a partial region of the images as a cutout region, and to display an image of the cutout region, and a speed setting unit to set a switch speed to switch the series of images from one image to a next, when displaying the series of images, in order. The control unit displays, in accordance with a change of the switch speed, the image of the cutout region, that is different from a region of the series of images displayed before the change of the switch speed, by changing a size of the cutout region. The control unit changes the size of the cutout region to be larger in accordance with the switch speed being changed to a faster speed.
