Abstract
Provided is an electronic device including an emission circuit configured to emit a first X-ray based on a clock in a second period when the period of the clock is changed from a first period to a second period and a processing circuit configured to output a first image data value based on a second X-ray received corresponding to the first X-ray or update a correction data value used to correct a first image data value, based on a control signal synchronized with the clock based on the first period.
Claims20
An electronic device comprising:
- an emission circuit configured to emit a first X-ray based on a clock in a second period, when the period of the clock is changed from a first period to the second period;
- and
- a processing circuit configured to output a first image data value based on a second X-ray, or to update a correction data value, based on a control signal synchronized with the clock based on the first period, the second X-ray being received corresponding to the first X-ray, the correction data value being used to correct the first image data value.
An electronic device comprising:
- an emission circuit configured to emit a first X-ray based on a clock having a second period changed from a first period;
- a detection circuit configured to generate a first image data value based on a second X-ray received based on the emitted first X-ray and to generate a second image data value based on a noise;
- and
- a processing circuit configured to calculate a third image data valuebased on the first image data value and a first correction data value, or to calculate a second correction data value based on the second image data value and the first correction data value, according to whether the clock having the second period comprises a pulse during the first period, the third image data value being related to an image of an object, the first correction data value and the second correction data value being related to the noise.
An electronic device comprising:
- a detection circuit configured to generate a first image data value based on a second X-ray received corresponding to a first X-ray outputted based on a clock;
- and
- a processing circuit configured to:
- generate a control signal related to reception of the second X-ray based on the clock,
- calculate a second image data value related to an image of an object, based on the first image data value and a first correction data value in response to a first logic value of the control signal, and
- calculate a second correction data value related to a noise based on the first image data value and the first correction data value in response to a second logic value of the control signal.
