Problems solved by technology
If the conventional digital imaging device is connected to the PC under the condition that the mode to be executed is not the previously selected mode, the conventional digital imaging device cannot smoothly perform data communication with the PC
This is because the conventional digital imaging device does not select and notify the PC drive mode, so that the PC cannot determine which firmware driver to put on the standby state
Furthermore, even if the device receives a run command for a particular mode from the PC, the conventional digital imaging device cannot determine which of the plug-in firmware it must access and execute for the selected mode function

A digital imaging apparatus and a method for selecting a data transfer mode thereof is disclosed. The digital imaging apparatus comprises a main storage unit for storing a firmware for at least two data transfer modes for transmitting image data acquired through a camera to an external device in different manners, respectively, and also storing a descriptor including information for identifying the firmware, a mode selection unit for outputting a mode selection signal for a certain transfer mode for the at least two data transfer modes, a transmitting module for connecting to the external device to transmit the image data to the external device, the transmitting module sending the image data in different data transfer manners for each data transfer mode, and a controlling unit which controls the transmitting module so as to set the transfer type corresponding to the selected certain transfer mode if the mode selection signal is received from the mode selection unit, and reads out descriptor of firmware corresponding to the selected transfer mode from the main storage unit and provides the descriptor to the transmitting module if the transmitting module is connected to the external device. Therefore, the digital imaging apparatus can efficiently perform communications with the external device by selecting a mode for execution before being connected to the external device.
Description
technical field [0001] The present invention generally relates to a digital imaging device and a method for selecting its data transmission mode, and more particularly, to a method for selecting a data transmission mode for communication with a computer, and then via a universal serial bus (hereinafter referred to as called "USB") interface to the computer, a digital imaging device capable of smoothly performing data communication with a computer, and a method for selecting its data transfer mode. Background technique [0002] A digital imaging device such as a digital video camera (DVC) uses a charge-coupled device (CCD) to convert an optical signal of an object into an electrical signal, and then converts the analog electrical signal into a digitized signal. The images recorded and reproduced as digital signals are generally of high quality, and the image quality is substantially not degraded. [0003] A recent technological innovation offered by the digital imaging devic...
