Abstract
A system for automatic image band detection includes concurrently capturing a first image of a scene with a first camera having a first exposure time and a second image of the scene with a second camera having a second exposure time. The system detects image banding for one of the first camera and the second camera based on the first image and the second image.
Claims20
A method, comprising:
- concurrently capturing a first image of a scene with a first camera having a first exposure time and a second image of the scene with a second camera having a second exposure time, wherein the first exposure time and the second exposure time are different;
- and
- detecting image banding for one of the first camera and the second camera based on comparing the first image and the second image to a subtractive difference between pixels of the first image and second image, wherein image banding is detected for the first camera based on the first image having a higher similarity to the subtractive difference than the second image.
A device, comprising:
- a first camera configured to capture a first image of a scene, the first image captured using a first exposure time, and a second camera configured to concurrently capture a second image of the scene, the second image captured using a second exposure time different from the first exposure time;
- a memory configured to store the first image and the second image received from each of the first camera and the second camera;
- and
- a processor communicatively coupled to the memory, the processor configured to:
- detect image banding for one of the first camera and the second camera based on comparing the first image and the second image to a subtractive difference between pixels of the first image and second image, wherein image banding is detected for the first camera based on the first image having a higher similarity to the subtractive difference than the second image.
2 more elements
A non-transitory computer readable medium having software instructions stored thereon that, when executed by a processor, cause the processor to:
- detect image banding for one of a first image captured by a first camera and a second image concurrently captured by a second camera based on comparing the first image and the second image to a subtractive difference between pixels of the first image and second image, wherein image banding is detected for the first camera based on the first image having a higher similarity to the subtractive difference than the second image, wherein the first image is captured by the first camera having a first exposure time and the second image is captured by the second camera having a second exposure time different from the first exposure time.
