Abstract:
1. An imaging apparatus comprising: a detector including a plurality of pixels arranged in an array, wherein each pixel of the plurality of pixels includes a conversion element for converting radiation or light into an electric charge, and the detector performs an imaging operation for outputting an image data according to an irradiation with the radiation or the light; and a controller for controlling an operation of the detector including the imaging operation, wherein the imaging operation includes a first imaging operation for outputting an image data according to the irradiation with the radiation or the light in a first irradiation field corresponding to a part of the plurality of pixels, and a second imaging operation for outputting an image data according to the irradiation with the radiation or the light in a second irradiation field of an area larger than that of the first irradiation field, wherein the second imaging operation includes an accumulating operation in which the detector is configured to convert the radiation or the light irradiated onto the conversion element into the electric charge, an image output operation in which the detector is configured to output the image data based on the electric charge, and an operation to initialize the conversion elements, which is performed before the accumulating operation, wherein the controller controls the operation of the detector such that, responsive to a changing from the irradiation in the first irradiation field to the irradiation in the second irradiation field, the detector performs an initializing operation for initializing the conversion elements during a period between the first imaging operation and the operation to initialize the conversion elements of the second imaging operation, and wherein the controller is configured to control the detector such that the initializing operation and the operation to initialize the conversion elements of the second imaging operation are each performed for a duration having a same length.
