Abstract

A radiation imaging apparatus includes a radiation detection unit with a pixel array configured to generate a signal according to radiation and a notification unit configured to perform notification by sound production. The radiation imaging apparatus includes: a detection unit configured to detect a plurality of notification events occurring in accordance with a state of the radiation imaging apparatus; and a control unit configured to control the notification by the notification unit based on priority set for each of the plurality of notification events.

First claim

What is claimed is:

1 . A radiation imaging apparatus that includes a radiation detection unit with a pixel array configured to generate a signal according to radiation and a notification unit configured to perform notification by sound production, the apparatus comprising:
a detection unit configured to detect a plurality of notification events occurring in accordance with a state of the radiation imaging apparatus; and a control unit configured to control the notification by the notification unit based on priority set for each of the plurality of notification events.

2 . The apparatus according to claim 1 , wherein while the control unit produces a first sound associated with a notification event from the notification unit, if a notification event higher in priority than the notification event is detected,
the control unit controls the notification unit so as to make a sound production time to produce the first sound shorter than a preset sound production time.

3 . The apparatus according to claim 2 , wherein the control unit controls the notification unit so as to finish producing the first sound in the middle of the preset sound production time and produce a second sound associated with the notification event of high priority.

4 . The apparatus according to claim 1 , wherein while the control unit produces a first sound associated with a notification event from the notification unit, if a notification event lower in priority than the notification event is detected,
the control unit controls the notification unit so as to produce a second sound associated with the notification event of low priority after the first sound is produced from the notification unit for a preset sound production time.

5 . The apparatus according to claim 4 , wherein the control unit controls the notification unit to silence after completion of sound production of the first sound and before a start of sound production of the second sound.

6 . The apparatus according to claim 5 , wherein based on a type of the notification event associated with the first sound, the control unit changes a setting of a silent time to set the notification unit to silence.

7 . The apparatus according to claim 5 , wherein based on a combination of a type of the notification event associated with the first sound and a type of the notification event associated with the second sound, the control unit changes a setting of a silent time to set the notification unit to silence.

8 . The apparatus according to claim 4 , further comprising a storage unit configured to store notification event information,
wherein if the notification event of low priority is detected while the first sound is produced from the notification unit, the control unit stores information on the notification event of low priority in the storage unit.

9 . The apparatus according to claim 8 , wherein after completion of sound production of the first sound, the control unit controls the notification unit so as to obtain the notification event information stored in the storage unit and produce the second sound associated with the obtained notification event information.

10 . The apparatus according to claim 1 , wherein if the detection unit detects a notification event during a readout period in which a signal is read out from the pixel array, the control unit sets the readout period as a sound production restricted period and restricts sound production from the notification unit.

11 . The apparatus according to claim 10 , wherein in a period in which the signal is read out from the pixel array includes a period in which an image signal is read out from the pixel array in order to obtain correction image data in a state without radiation irradiation and radiation image data after radiation irradiation.

12 . The apparatus according to claim 11 , wherein the sound production restricted period includes a period in which the correction image data and the radiation image data are digitized.

13 . The apparatus according to claim 1 , wherein the state of the radiation imaging apparatus includes a state in which radiation imaging processing is started.

14 . The apparatus according to claim 1 , wherein the state of the radiation imaging apparatus includes a state in which an irradiation sensable time for sensing radiation irradiation is smaller than a reference value.

15 . The apparatus according to claim 1 , further comprising an image storage unit configured to store image data,
wherein the state of the radiation imaging apparatus includes a state in which image data that is stored in the image storage unit and is not transferred to an external apparatus exists.

16 . The apparatus according to claim 1 , further comprising an operation unit configured to accept an operation setting for performing imaging,
wherein the state of the radiation imaging apparatus includes a state in which a setting of the radiation imaging apparatus based on the operation setting by the operation unit is changed.

17 . The apparatus according to claim 1 , wherein the state of the radiation imaging apparatus includes a state in which an imaging mode of the radiation imaging apparatus is changed.

18 . A method of controlling a radiation imaging apparatus that includes a radiation detection unit with a pixel array configured to generate a signal according to radiation, the method comprising:
detecting a plurality of notification events occurring in accordance with a state of the radiation imaging apparatus; and controlling the notification by sound production based on priority set for each of the plurality of notification events.

19 . A non-transitory computer readable storage medium storing a program for causing a computer to execute a method of controlling a radiation imaging apparatus that includes a radiation detection unit with a pixel array configured to generate a signal according to radiation, the method comprising:
detecting a plurality of notification events occurring in accordance with a state of the radiation imaging apparatus; and controlling the notification by sound production based on priority set for each of the plurality of notification events.
