Abstract
Image processing apparatus having a data processing unit, a first interface having a plurality of logical channels for connecting with an external processing apparatus, a second interface having a logical channel that has a different configuration from the first interface for connecting with the data processing unit, and a control unit for controlling data transfer between the first interface and second interface.
Claims6
A control method of an image processing apparatus, the image processing apparatus including (a) a data processing unit;
- (b) a first interface unit, having a plurality of logical channels, which is adapted to connect with an external processing apparatus;
- and (c) a second interface unit, having a logical channel that has a configuration different from the first interface unit, which is adapted to connect with the data processing unit, said method comprising:
- controlling data transfer between the first interface unit and the second interface unit;
- and
- acquiring attribute information possessed by the data processing unit through the second interface unit;
- integrating the acquired attribute information and attribute information for each of the plurality of logical channels provided in the first interface unit;
- and
- notifying the integrated attribute information.
A control method of an image processing apparatus, the image processing apparatus including (a) a data processing unit;
- (b) a first interface unit, having a plurality of logical channels, which is adapted to connect with an external processing apparatus;
- and (c) a second interface unit, having a logical channel that has a configuration different from the first interface unit, which is adapted to connect with the data processing unit, said method comprising:
- controlling data transfer between the first interface unit and the second interface unit,
- wherein the first interface unit and the second interface unit are controlled so that an image data processing status is acquired from the data processing unit through the second interface unit, and the acquired processing status is transferred to the external processing apparatus through the logical channel, which is provided in the first interface unit, for the data processing unit.
A control method of an image processing apparatus, the image processing apparatus including (a) a data processing unit;
- (b) a first interface unit, having a plurality of logical channels, which is adapted to connect with an external processing apparatus;
- and (c) a second interface unit, having a logical channel that has a configuration different from the first interface unit, which is adapted to connect with the data processing unit, said method comprising:
- controlling data transfer between the first interface unit and the second interface unit,
- wherein the first interface unit and the second interface unit are controlled so that image data is received through a logical channel, which is provided in the first interface unit, for the data processing unit, and the received image data is transferred to the data processing unit through the second interface unit, and
- wherein an image-data-reception standby state of the data processing unit is detected through the second interface unit, and the detected image-data-reception standby state is set as an image-data-reception standby state to be transmitted through the logical channel, which is provided in the first interface unit, for the data processing unit.
