Patent number: 10356300Abstract: 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.Type: GrantFiled: October 2, 2017Date of Patent: July 16, 2019Assignee: MEDIATEK INC.Inventors: Ping-Han Lee, Yu-Pao Tsai
