1. A control device which performs radiation imaging by controlling a digital radiation imaging apparatus, the device comprising:
- a detection unit which detects an imaging instruction in a specific imaging mode;
a transferring unit which performs a transfer of outside radiation image data obtained by the digital radiation imaging;
a control unit which executes retransmission processing within a retransmission timeout time when the transfer fails; and
a setting unit which sets, in a first imaging mode, a retransmission timeout time limit for an item of image data that is to be transferred last, in a time sequence of image data transfer, to be different from a retransmission timeout time limit for at least one other item of image data to be transferred.

Abstract
In transfer of image data (such as an X-ray image), if for example a transfer error occurs, a retransmission timeout time limit for an item of image data that is to be transferred last, in a time sequence of image data transfer, is set to be different from a retransmission timeout time limit for at least one other item of image data which is to be transferred.

5. An X-ray imaging apparatus comprising:
-
an X-ray image generating unit which detects X-rays transmitted through an object and generates an X-ray image of the object based on the detected X-rays; and a control unit which acquires the X-ray image from said X-ray image generating unit and transfers the X-ray image to a functional unit which processes the X-ray image, wherein said control unit retransmits, to the functional unit, one X-ray image acquired by said X-ray image generating unit within a preset retransmission time, when a retransmission request for the X-ray image is received from the functional unit after the X-ray image is transferred to the functional unit, wherein said control unit sets, as the retransmission time, a period until a start of capturing of a next X-ray image after the transfer, when a moving image mode for capturing a plurality of X-ray images by continuously capturing X-ray images is set, and wherein said control unit sets a predetermined time as the retransmission time when a still image mode for capturing one X-ray image is set. - View Dependent Claims (6, 7)
