A electronic device includes a plurality of first photosensitive chips, one first fusion chip, and one processing chip. Each first photosensitive chip is connected to the first fusion chip by a respective data transmission channel and is configured both to generate a MIPI protocol-based data stream and to transmit said data stream to the first fusion chip by the respective data transmission channel. The first fusion chip is connected to the processing chip by a data transmission channel and is configured to converge data streams received via a plurality of data transmission channels connected to the plurality of first photosensitive chips, to obtain a first high-speed convergent data, and to send the first high-speed convergent data to the processing chip. The processing chip is configured to receive the high-speed convergent data stream and obtain an image by using the received data stream.
