Abstract
An image capture system for enhanced electronic image stabilization (EIS) includes an image capture device and an adapter lens. The image capture device includes an image sensor, a lens housing, a processor, and a lens assembly that includes a first group of optical elements disposed within the lens housing. The first group of optical elements are used project an image onto the image sensor. The processor performs EIS. The adapter lens is used to enhance EIS of the image capture device. The adapter lens has an adapter lens housing that interfaces with the lens housing. The lens housing automatically detects the adapter lens.
Claims20
An image capture system comprising:
- an image capture device comprising:
- an image sensor;
- a lens housing;
- a lens assembly comprising a first group of optical elements disposed within the lens housing;
- and
- a processor configured to perform electronic image stabilization (EIS);
- and
- an adapter lens configured to enhance EIS of the image capture device, the adapter lens comprising:
- an adapter lens housing configured to interface with the lens housing, wherein the lens housing is configured to automatically detect the adapter lens;
- and
- a second group of optical elements disposed within the adapter lens housing, wherein the second group of optical elements is configured to project an image as an image circle on the image sensor;
- wherein the processor is further configured to adjust an EIS algorithm based on the detected adapter lens.
An image capture device comprising:
- an image sensor;
- a lens housing configured to couple to and automatically detect a detachable adapter lens configured to enhance electronic image stabilization (EIS);
- a lens comprising a first group of optical elements disposed within the lens housing;
- and
- a processor configured to perform EIS, wherein the processor is configured to adjust an EIS algorithm based on the detected detachable adapter lens.
A method for enhanced electronic image stabilization (EIS) comprising:
- detecting an adapter lens;
- adjusting an EIS algorithm based on the adapter lens;
- applying the adjusted EIS algorithm to video frames to obtain stabilized frames;
- and
- outputting the stabilized frames as stabilized video.
