Imaging adjusting method capable of varying scaling ratios and related camera and image processing system
First Claim
1. An image adjusting method capable of varying scaling ratios according to different regions of an image, the image adjusting method comprising:
- setting a first ROI (region of interest) circle on the image;
acquiring a center of the first ROI circle to be a first reference point;
setting at least one first bridging region circle by the first reference point, wherein a dimension of the first bridging region circle is greater than a dimension of the first ROI circle;
utilizing a first scaling ratio, a second scaling ratio and a third scaling ratio to respectively adjust pixels inside the first ROI circle, pixels between the first bridging region circle and the first ROI circle, and pixels between the first bridging region circle and a boundary of the image, so as to vary resolution of the whole image;
setting a second ROI (region of interest) circle on the image;
acquiring a center of the second ROI circle to be a second reference point,setting at least one second bridging region circle by the second reference point, wherein a dimension of the second bridging region circle is greater than a dimension of the second ROI circle;
utilizing a fourth scaling ratio, a fifth scaling ratio and the third scaling ratio to respectively adjust pixels inside the second ROI circle, pixels between the second bridging region circle and the second ROI circle, and pixels out of the second bridging region circle;
determining whether to combine the first ROI circle with the second ROI circle; and
combining the first ROI circle with the second ROI circle while a determination of combining the first ROI circle with the second ROI circle is confirmed.

Abstract
An image adjusting method capable of varying scaling ratios according to different regions of an image includes setting a first ROI (region of interest) circle on the image, acquiring a center of the first ROI circle to be a first reference point for setting at least one first bridging region circle, and utilizing a first scaling ratio, a second scaling ratio and a third scaling ratio to respectively adjust pixels of the first ROI circle, pixels between the first bridging region circle and the first ROI circle, and pixels out of the first bridging region circle. Dimension of the first bridging region circle is greater than dimension of the first ROI circle, and the first scaling ratio and the third scaling ratio are greater than the second scaling ratio. Further, the foresaid image adjusting method is applied to a camera and a related image processing system with image adjusting function.
