Image Processing Apparatus Magnifies Background for Follow Shot Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing follow shot technique in image capturing struggles to display still images effectively on small display units, making it difficult for users to assess the quality of stillness of the main object and flow of the background due to differences in panning speed between the camera and the moving object.
Innovation Solution
An image processing apparatus that acquires background motion vectors from multiple positions in a moving image and performs a magnification display process to highlight the background area, allowing the display unit to show a magnified background area compared to the entire still image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire still image is displayed on the small display unit, then the display is simple, but the user cannot check the image quality (degree of stillness of main object and degree of flowing of background)
Solution Approach 1:
The patent divides the still image into multiple regions (main object region and background region) and selectively magnifies specific regions for display. This segmentation allows the small display unit to show detailed quality information of critical areas without requiring a larger display area, thus resolving the contradiction between displaying complete image quality information and the limited display size.
Solution Approach 2:
The patent transitions from displaying the entire image at normal scale to displaying magnified portions of specific regions. This dimensional change in display scale allows detailed quality assessment of the main object and background to be presented on the limited display unit, effectively overcoming the area constraint while preserving image quality information.
2Length of moving object
If the display unit size is small, then the device is compact, but it is difficult for the user to check the degree of stillness of the main object and the degree of flowing of the background
Solution Approach 1:
The patent applies different display qualities to different regions of the image. By magnifying the main object region and background region separately, the system provides high measurement precision for image quality assessment in these critical areas, even though the overall display unit remains small. This local quality enhancement allows users to evaluate the degree of stillness and flowing effectively.
3Device complexity
If the still image is displayed without magnification, then the display process is simple, but the user cannot adequately assess the follow shot quality
Solution Approach 1:
The patent performs preliminary processing to identify and extract the main object region and background region before display. By pre-segmenting the image and determining which regions require magnification for quality assessment, the system minimizes the complexity of the display process while ensuring that critical follow shot quality information is not lost. The magnification is applied selectively based on this preliminary analysis.

AI summary
The image processing apparatus performing a process for displaying a still image acquired by an image capturing apparatus during its panning to follow a moving main object. The image processing apparatus includes a vector acquiring unit configured to acquire, from multiple motion vectors detected in a moving image acquired by the image capturing apparatus during the panning, a background motion vector, and a processing unit configured to determine, using the background motion vector, a background area of the still image where a background object is captured and to perform a magnification display process for magnifying the background area as compared with a case where the display unit displays the entire still image and causing the display unit to display the magnified background area.
