Abstract: A dual-camera device is provided. The dual-camera device includes wide and telephoto imaging sections with respective lens/sensor combinations, and a processor. The wide and telephoto imaging sections provide wide image data and telephoto image data, respectively. At least one misalignment error exists between the wide and telephoto imaging sections. The processor generates an output image provided with a smooth transition when switching between a lower zooming factor and a higher zooming factor. The processor warps the wide image data using a portion of the misalignment error to generate base wide image data, and warps the telephoto image data using the remaining portion of the misalignment error to generate base telephoto image data. The processor generates the output image using the base wide image data at the lower zooming factor, and generates the output image using the base telephoto image data at the higher zooming factor.

Abstract: A camera device is provided. The camera device includes: a first imaging section, a second imaging section, a third imaging section, and a processor. The first imaging section, second imaging section, and third imaging section capture a first image, a second image, and a third image of a scene with a first field of view (FOV), a second FOV1 and a third FOV. The processor is configured to generate a first output image by performing a first image-fusion process on the first image, the second image, and a third image in response to a zooming factor of the camera device being between a first zooming factor and a second zooming factor, wherein the first FOV is wider than the second FOV, and the second FOV is wider than the third FOV, and the second zooming factor is greater than the first zooming factor.
