Vehicle Viewing Device Dynamic Compression Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle viewing devices limit the range of moving the display position of images by requiring structural changes or maintaining constant compression rates, restricting the ability to change the viewing range without abutting image edges.
Innovation Solution
A system that combines partial and compressed images, allowing the control section to adjust the positions and compression rates of these images within the display, enabling the display of a wider angle view and extending the range of moving the display position by changing the compression rate or border positions in response to the size of the peripheral image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of cutting out the partial image and peripheral image is changed to move the display position, then the viewing range can be changed, but the range of moving is limited when the end portion of the displayable image abuts the end portion of the captured image
Solution Approach 1:
The patent changes the compression rate of the compressed image as a parameter when the end portion of the displayable image abuts the end portion of the captured image. This allows the system to continue expanding the display position movement range by adjusting the compression rate rather than being limited by the fixed boundary condition
Solution Approach 2:
The patent makes the compression rate dynamic rather than fixed. The compression rate is automatically adjusted based on the size of the peripheral image and the abutting condition, enabling continuous adaptation and extending the operational range of display position movement
2Adaptability or versatility
If the compression rate of the compressed image is changed to enlarge the display position movement range, then the viewing flexibility is improved, but the image quality and size consistency may be affected
Solution Approach 1:
The compression rate is made dynamically adjustable based on the size of the peripheral image. The control section automatically determines the appropriate compression rate to maintain image size consistency while enabling the display position movement range to be enlarged
Solution Approach 2:
The system changes the compression rate parameter in response to the peripheral image size and abutting condition, allowing flexible adjustment of the compressed image dimensions to maintain consistency while expanding operational capabilities

AI summary
A viewing device for a vehicle has: a monitor (14) that displays an image for viewing that combines a partial image, which is obtained by cutting out a portion of a captured image, and a compressed image, which is obtained by cutting out a peripheral image corresponding to a portion of a periphery of the partial image of the captured image and compressing a size more than the partial image; and a control section (18) that, in a case of changing a viewing range of the image for viewing, changes respective positions of cutting out the partial image and the peripheral image from the captured image, and controls the monitor (14) to display the image for viewing with at least one of a compression rate of the compressed image and a border position of the partial image and the compressed image within the image for viewing being changed in accordance with a changed size of the peripheral image.
