When sending photographic image data obtained in an electronic cameravia a communication interfaceto a radio telephone line of a PDC, a PHS, etc., an RISC-CPUconverts the image data to data having a configuration allowing communication and further converts by software processing the communication-allowing configuration data to data corresponding to the type of the radio telephone line.

Imaging device

An electronic camera is disclosed, which has a USB host detector for checking whether a host computer other than itself is connected to a universal series bus. When it is detected that no host computer other than the camera is connected, a host mode is set, in which a USB host controller is operated to set the camera as host. When it is detected that a host computer other than the camera is connected, a terminal mode is set, in which the camera is operated under control of the other host computer.

Connector for coupling electronic imaging system with USB that selectively switches USB host controller and USB interface with connector

When sending photographic image data obtained in an electronic camera via a communication interface to a radio telephone line of a PDC , a PHS , etc., an RISC-CPU converts the image data to data having a configuration allowing communication and further converts by software processing the communication-allowing configuration data to data corresponding to the type of the radio telephone line.

An image data conversion device includes a variable-length code decoder which decodes compressed image data which has been compressed through processes of orthogonal transform, quantization, and variable-length coding. A data amount calculation unit calculates an amount of data that corresponds to a predetermined number of pixels from the results of decoding by the variable-length code decoder. A delimiter code insertion unit inserts a delimiter code in a position in image data where the amount of data calculated by the data amount calculation unit corresponds to the predetermined number of pixels.

Image data conversion device and method having function of inserting

An image incident on an image sensor is photoelectrically converted to digital image data and stored on a storage device or medium in a hierarchical form as a file in a directory or subdirectory supported by a disk operating system. In this way, the system realizes an electronic imaging apparatus fully compatible with a personal computer.
