摘要:
A method is provided for controlling a Mass Storage Class Digital Imaging Device using a SCSI pass through protocol. The protocol is based on industry standard SCSI protocol with modifications and extensions to allow transparent communication over a medium and is referred to as SCSI Pass Through (SPT). This protocol defines a set of commands that are initiated in a computer. The commands also include and extend industry standard Picture Transfer Protocol and are targeted for application and execution in a Mass Storage Class Digital Imaging Device. The invention includes the definition of data buffers in the form of data structures that can be used for packaging, passing, and receiving information related to the digital imaging device. The protocol is applicable to communication mediums that can be utilized in connecting any digital storage device to a computing device.

A computer system uses simplified device drivers for operating hardware devices. A simplified device driver for a hardware device of a given device type, such as a flatbed scanner, works with a system-supplied common driver for that given device type. The common driver and the simplified driver together function like a regular device driver. The simplified device driver implements a small number of entry point functions corresponding to a pre-selected set of operation commands “generic” to hardware devices of that given device type. When an application makes a request for an operation by the device, the request is passed through a device driver interface (DDI) to the common driver. The common driver then calls the entry point functions in the simplified device driver to carry out the requested operation.

A system and method for image acquisition enables selective automated application of color management to color image data generated by an image-capturing device by the device driver for the device. In the image acquisition system, each image-capturing device has properties or operation parameters that can be set to control the operation of the device. During an image acquisition operation, color image data generated by the image-capturing device are transmitted to the device driver. If the operation parameters of the device are set to indicate that color management is to be performed, the device driver calls color management functions provided by the operating system to perform the desired color operation, such as a color space conversion, on the received color image data. The processed color image data are then sent to the image-processing application for further processing or editing.

A computer system and method uses script-based device drivers for operating hardware devices. The script-based driver architecture comprises a scripting driver, a script engine, and a driver script for a given hardware device, such as a scanner. The driver script is generally a text file containing a sequence of programming instructions defining the operational behavior of the hardware device. The scripting driver exports a set of objects whose functions can be called by the driver script to communicate with and control the device. When a request to operate the hardware device is received by the scripting driver, the script engine interprets the programming instructions in the driver script corresponding to the request and invokes the functions of the scripting driver objects called by the programming instructions to carry out the requested device operation.
