Abstract
Abstract A server which smoothly transmits/receives a moving image from image sensing device via the Internet. The server comprises a camera which converts an object image into an image signal, a camera controller which controls the camera, and a camera driver. When the image signal converted by the camera is transferred as still-image data on the Internet, the data is transferred by the HTML or HTTP protocol, on the other hand, when the image signal is transferred as moving-image data, the data is transferred by another protocol.
