BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a radiation imaging system, a control method thereof, a system and a control method thereof.

Description of the Related Art

In recent years, in a radiation imaging system widely used in the industrial field, medical field, and the like, a portable radiation imaging apparatus capable of imaging in a plurality of imaging modes, such as still image capturing and moving image capturing, suitable for purposes has been studied. A portable radiation imaging apparatus often communicates with a control apparatus using wireless communication to improve portability.

Japanese Patent Laid-Open No. 2018-7851 discloses an example of the radiation imaging system that performs still image capturing and moving image capturing using wireless communication between a radiation imaging apparatus and a control apparatus.

A wireless communication environment changes from time to time due to the distance between apparatuses that communicate with each other, obstacles therebetween, radio wave interference from another wireless communication apparatus, or the like. As the wireless communication environment changes, the stability and communication rate of wireless communication also change, and problems such as a case in which the communication rate required for transmitting image data cannot be ensured so moving image capturing cannot be performed are likely to occur.

The radiation imaging system disclosed in Japanese Patent Laid-Open No. 2018-7851 obtains the communication rate between the radiation imaging apparatus and the control apparatus, and enables moving image capturing if the communication rate is equal to or higher than a specified value.

However, in the radiation imaging system disclosed in Japanese Patent Laid-Open No. 2018-7851, an operator cannot recognize the margin in a communication state. Therefore, for example, when moving image capturing is selected in a state in which only the insufficient margin is left for the communication rate, there can be a case in which moving image capturing cannot be performed due to a slight decrease in communication rate.

The present invention has been made in consideration of the above problem, and provides a radiation imaging technique capable of displaying information indicating the margin in a communication state.

SUMMARY OF THE INVENTION

According to one aspect of the present invention, there is provided a radiation imaging system comprising a radiation imaging apparatus having a plurality of imaging modes, and a control apparatus configured to control imaging of a radiation image with respect to the radiation imaging apparatus, comprising: an obtaining unit configured to obtain information with respect to a communication state between the radiation imaging apparatus and the control apparatus; and a display control unit configured to cause a display unit of at least one of the radiation imaging apparatus and the control apparatus to display information indicating a margin in the communication state based on an imaging mode of the radiation imaging apparatus and the information with respect to the communication state.

According to another aspect of the present invention, there is provided a system comprising a portable terminal apparatus capable of playing image data, and a control apparatus configured to transmit image data to the portable terminal apparatus, comprising: an obtaining unit configured to obtain information with respect to a communication state between the portable terminal apparatus and the control apparatus; and a display control unit configured to cause a display unit of the portable terminal apparatus to display information indicating a margin in the communication state based on an image quality level of image data for playback and the information with respect to the communication state.

According to still another aspect of the present invention, there is provided a control method of a radiation imaging system comprising a radiation imaging apparatus having a plurality of imaging modes, and a control apparatus configured to control imaging of a radiation image with respect to the radiation imaging apparatus, comprising: obtaining information with respect to a communication state between the radiation imaging apparatus and the control apparatus; and causing a display unit of at least one of the radiation imaging apparatus and the control apparatus to display information indicating a margin in the communication state based on an imaging mode of the radiation imaging apparatus and the information with respect to the communication state.

According to yet another aspect of the present invention, there is provided a control method of a system comprising a portable terminal apparatus capable of playing image data, and a control apparatus configured to transmit image data to the portable terminal apparatus, comprising: obtaining information with respect to a communication state between the portable terminal apparatus and the control apparatus; and causing a display unit of the portable terminal apparatus to display information indicating a margin in the communication state based on an image quality level of image data for playback and the information with respect to the communication state.

According to the present invention, it becomes possible to display information indicating the margin in a communication state. By displaying the margin in the communication state, it becomes possible for an operator to grasp the reliability of communication, and convenience in imaging can be improved.

Further features of the present invention will become apparent from the following description of exemplary embodiments (with reference to the attached drawings).
