PROBLEM TO BE SOLVED: To provide a digital camera and a data transfer method, in a system even where an image photographed by the digital camera is transferred to a mobile phone or other external device and displayed therein, image quality is maintained to the utmost and data are transferred surely even when data of a large image size in excess of a built-in memory capacity of the external device are designated as a transfer object. SOLUTION: The digital camera 10 and the mobile phone 30 are connected to conduct negotiation by communication between them, and the digital camera 10 acquires information with respect to a capacity of a built-in buffer 90A of the mobile phone 30. The digital camera 10 applies image conversion to the image data which are transfer objects by revising a Huffman table and a quantization table so as to reduce the file size, thereby limiting the data quantity so as to be within the capacity of the built-in buffer size 90A. The transmission data 97, produced in this way, are transferred to the mobile phone 30 and stored in the built-in buffer 90A. |
