Abstract: A system and mobile device for generating a panoramic video is presented. The system comprises a plurality of cameras and a mobile device. The mobile device further comprises a CPU and a GPU. The plurality of cameras is operable to capture video frames from different directions through 360° to generate multi-channel video streams. The CPU is configured to issue to the GPU an instruction to process the multi-channel video streams. The GPU is configured to mosaic synchronous video frames of the multi-channel video streams by utilizing parallel computing according to the instruction, so as to generate the panoramic video in real time.
