Benefits of technology

The inventive feature described in this patented design allows for easy adjustments when focused on specific areas or parts within an image without having to move it around all over again. This makes it easier than previous designs where multiple components were needed. Additionally, there are fewer constraints with these devices due to their compact size compared to traditional methods like lenses. Overall, they make imaging systems more efficient while reducing its overall dimensions.

Problems solved by technology

This patented technical solution describes an issue with current manual rotation of focused rings in cameras modules due to their poor alignment precision when changing lens settings during testing. Additionally, there are limitations on how well they can achieve automatic focus by moving them closer together from one device to another without requiring excessive effort.
