Abstract
A radiation imaging apparatus that generates an image by receiving radiation transmitted through an object, comprises a sensor array configured to detect radiation, an obtaining unit configured to obtain an image signal from a detection signal of the sensor array, a power reception unit configured to receive power supplied from outside, and battery that is charged by using the power received by the power reception unit. The radiation imaging apparatus generates, in response to the satisfaction of a predetermined condition after power reception is started by the power reception unit, an image for correction by obtaining the image signal from the obtaining unit.
Claims17
A radiation imaging apparatus that generates an image by receiving radiation transmitted through an object, comprising:
- a sensor array configured to detect radiation;
- an obtaining unit configured to obtain an image signal from a detection signal of the sensor array;
- a power reception unit configured to receive power supplied from outside;
- a battery that is charged using the power received by the power reception unit;
- and
- a generating unit configured to generate an image for correction by obtaining the image signal by the obtaining unit in response to detection that the power reception unit has stopped receiving the power.
A radiation imaging apparatus that generates an image by receiving radiation transmitted through an object, comprising:
- a sensor array configured to detect radiation;
- an obtaining unit configured to obtain an image signal from a detection signal of the sensor array;
- a power reception unit configured to receive power supplied from outside;
- a battery that is charged using the power received by the power reception unit;
- and
- a generating unit configured to generate an image for correction when a charge amount of the battery has reached a charge amount in which radiation moving image capturing can be executed, and configured not to generate the image for correction when the charge amount of the battery has not reached the charge amount in which radiation moving image capturing can be executed.
A radiation imaging apparatus that generates an image by receiving radiation transmitted through an object, comprising:
- a sensor array configured to detect radiation;
- an obtaining unit configured to obtain an image signal from a detection signal of the sensor array;
- a power reception configured to receive power supplied from outside;
- a battery that is charged using the power received by the power reception unit;
- and
- a generating unit configured to start generation of an image for correction by obtaining the image signal by the obtaining unit at a predetermined time interval in response to a charge amount of the battery reaching a charge amount in which radiation moving image capturing can be executed.
A radiation imaging apparatus that generates an image by receiving radiation transmitted through an object, comprising:
- a sensor array configured to detect radiation;
- an obtaining unit configured to obtain an image signal from a detection signal of the sensor array;
- a power reception unit configured to receive power supplied from outside;
- a battery that is charged using the power received by the power reception unit;
- a generating unit configured to generate an image for correction by obtaining the image signal from the obtaining unit in response to the satisfaction of a predetermined condition after power reception is started by the power reception unit;
- and
- a setting unit configured to set whether to perform moving image capturing or still image capturing, wherein
- the generating unit executes the generation of the image for correction when the moving image capturing is set and does not execute the generation of the image for correction when the still image capturing is set.
A control method of a radiation imaging apparatus that generates an image by receiving radiation transmitted through an object, the method comprising:
- obtaining an image signal from a detection signal of a sensor array configured to detect radiation;
- receiving power supplied from outside;
- charging a battery using the received power;
- and
- generating an image for correction by obtaining the image signal in response to detection that reception of the power has stopped.
A non-transitory computer readable storage medium storing a program for causing a computer to execute a control method of a radiation imaging apparatus that generates an image by receiving the radiation transmitted through an object, the method comprising:
- obtaining an image signal from a detection signal of a sensor array configured to detect radiation;
- receiving power supplied from outside;
- charging a battery using the received power;
- and
- generating an image for correction by obtaining the image signal in response to detection that reception of the power has stopped.
