A radiation imaging apparatus has a sensor that converts irradiated radiation into a charge in accordance with a radiation dose, a switching power supply for supplying power to at least the sensor, and a readout unit that reads out a signal corresponding to the charge from the sensor. The radiation imaging apparatus synchronizes the imaging synchronization signal and a control clock for a switching operation of the switching power supply, causes a readout of signal from the sensor by the readout unit to be executed, and adjusts the phase of the control clock in each cycle of the imaging synchronization signal so that a timing of the imaging synchronization signal that occurs cyclically is at the same phase of the control clock.

A method and a system are disclosed that use a double-readout technique to generate timestamps and grayscale values for pixel-specific outputs of a pixel row in a pixel array in which the pixel array forms an image plane and the row of pixels forms an epipolar line of a scanning line on the image plane. For a pixel-specific output that exceeds a threshold, a timestamp value and a grayscale value are generated and associated with the pixel-specific output. If a pixel-specific output does not exceed the threshold and no timestamp is generated (i.e., a missing timestamp), a grayscale value for the pixel-specific output is generated and associated with the pixel-specific output. Timestamps errors may be corrected that may be caused by missing timestamps, timestamps that are associated with pixel clusters and outlier timestamps, i.e., pixel-specific outputs that are not consistent with a monotonic relationship of timestamp values under normal conditions.

A current comparison unit receives light incident on a pixel, performs photoelectric conversion to generate a voltage, compares a current generated from the voltage with reference to a first potential line and a reference current generated with reference to a second potential line, the first potential line being one of a power supply line and a grounding line, the second potential line being another one of the power supply line and the grounding line, and outputs a comparison. A feedback unit returns a signal to a source side in the current comparison unit when the current is generated, the signal using the comparison result by the current comparison unit. The feedback unit can perform standby control in the current comparison unit.

Noise is reduced in a circuit that converts voltage. A voltage conversion circuit includes a conversion transistor, a current source transistor, and a control circuit. In this voltage conversion circuit, the conversion transistor converts a potential of an input signal, the potential being changed from one of two different potentials to the other, by using predetermined current, and outputs the converted signal as an output signal. Furthermore, the current source transistor supplies the predetermined current. Then, in a case where the potential of the input signal is changed to the other potential, the control circuit stops supplying the predetermined current.
