Abstract
A radiation imaging apparatus includes a pixel configured to generate a charge based on radiation, a readout circuit that reads out the charge from the pixel, a drive unit that drives the readout circuit, and an image processing unit that reads out the charge from the readout circuit and generates an image, and performs first control to supply power to the drive unit and the image processing unit and second control to supply power to the drive unit and not to the image processing unit.
Claims7
A radiation imaging apparatus comprising:
- a pixel configured to generate a charge based on radiation;
- a readout circuit configured to read out the charge from the pixel;
- a drive unit configured to drive the readout circuit;
- an image processing unit configured to read out the charge from the readout circuit and generate an image based on the charge;
- a power supply unit configured to supply power to the drive unit and the image processing unit;
- and
- a control unit configured to control the drive unit, the image processing unit, and the power supply unit,
- wherein the control unit performs first control to cause the power supply unit to supply power to the drive unit and the image processing unit and second control to cause the power supply unit to supply power to the drive unit and not to supply power to the image processing unit, and
- wherein the first control is performed subsequent to the second control.
