Abstract: An image enhancement method applied to an image enhancement apparatus and includes acquiring a first edge feature from a first spectral image and a second edge feature from a second spectral image, analyzing similarity between the first edge feature and the second edge feature to align the first spectral image with the second spectral image, acquiring at least one first detail feature from the first spectral image and at least one second detail feature from the second spectral image, comparing the first edge feature and the second edge feature to generate a first weight and a second weight, and fusing the first detail feature weighted by the first weight with the second detail feature weighted by the second weight to generate a fused image. The first spectral image and the second spectral image are captured at the same point of time.

Abstract: A camera tuning circuit has a first storage space, a second storage space and a controller. The first storage space stores a first reference camera correction setting for a reference camera module under a first color temperature. The second storage space stores a second reference camera correction setting for the reference camera module under a second color temperature, wherein the second color temperature is different from the first color temperature. The controller receives a default camera correction setting of a target camera module, the first reference camera correction setting, and the second reference camera correction setting, and generates a tuned camera correction setting for the target camera module according to the default camera correction setting, the first reference camera correction setting, and the second reference camera correction setting.

Abstract: An image calibration method is applied to an image calibration device includes an image receiver and an operation processor. The image calibration method of providing a motion deblur function includes driving a first camera to capture a first image having a first exposure time, driving a second camera disposed adjacent to the first camera to capture a second image having a second exposure time different from and at least partly overlapped with the first exposure time, and fusing a first feature of the first image and a second feature of the second image to generate a fusion image.
