Image Processing Device for Panoramic Aspect Ratio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panoramic imaging technologies lack the ability to restrict the aspect ratio of generated images, making it difficult to produce composite images with desired ratios, especially when printing, as they often result in non-standard aspect ratios like 4:3 or 16:9.
Innovation Solution
An image processing device and method that allows users to set a desired aspect ratio for panoramic images by combining multiple images captured while moving the camera horizontally, with the CPU controlling image processing to trim and resize the images to the specified aspect ratio, such as 4:3 or 16:9, while minimizing hardware burden and energy consumption.

Engineering Contradiction Analysis
1Adaptability or versatility
If panoramic imaging is performed without aspect ratio limitation, then the viewing angle range can be captured freely within 360 degrees, but the generated composite image has non-standard aspect ratio which is inconvenient for printing and other purposes
Solution Approach 1:
The system performs preliminary action by determining the optimal composite image generation range before actually generating the composite image. The aspect ratio determining unit calculates the required aspect ratio based on the number of captured images and their arrangement, allowing the system to pre-plan the composition to achieve standard aspect ratios (4:3 or 16:9) while capturing the desired viewing angle range.
Solution Approach 2:
The system applies parameter changes by dynamically adjusting the composite image generation range based on the captured image count and desired aspect ratio. The aspect ratio determining unit modifies the horizontal arrangement parameters of the composite image to transform non-standard aspect ratios into standard ones, while the image generating unit adapts the composite image creation process accordingly.
2Manufacturing precision
If the composite image generation range is determined based on captured image count, then standard aspect ratios can be achieved, but additional processing steps are required
Solution Approach 1:
The system achieves universality by creating a multi-functional aspect ratio determining unit that can handle multiple aspect ratio standards (4:3, 16:9, and others) through a single integrated process. This unit simultaneously performs image count analysis, aspect ratio calculation, and composite image range determination, eliminating the need for separate processing modules for different aspect ratios.
Solution Approach 2:
The system uses parameter changes to simplify processing by dynamically adjusting the composite image generation parameters based on the desired aspect ratio. Instead of implementing complex separate processing pipelines for different aspect ratios, the system modifies the horizontal arrangement parameter (number of images per row) to achieve the target aspect ratio, reducing overall system complexity.

AI summary
A digital camera according to the present invention includes a CCD, a CPU and an image processing section. The CPU sets an arbitrary aspect ratio, and acquires a composite image having a predetermined aspect ratio which has been generated by a plurality of images consecutively captured by the CCD being combined. The image processing section trims the composite image acquired by the CPU to be an image having the set arbitrary aspect ratio.
