IMAGING DEVICE, IMAGING SYSTEM, CONTROL METHOD THEREOF, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an imaging device capable of preventing significant degradation in picture quality by reducing image steps caused by the effect of radiation region which can occur in an acquired image with no complex image processes.

SOLUTION: An imaging device 100 includes: a detector 104 in which a plurality of pixels are arranged in a matrix to perform an imaging operation such as output of image data corresponding to the light or ray irradiated in a predetermined irradiation field; and a control part 106. The imaging operation includes: a first imaging operation for outputting the image data corresponding to the light or ray irradiated on the detector in an irradiation field A corresponding to a portion of pixels contained in a plurality of pixels; and a second imaging operation for outputting the image data corresponding to the light or radiation irradiated to the detector 104 in an irradiation field B wider than the irradiation field A. The control part 106 controls an operation of the detector to accumulate the second imaging operation for an accumulation time determined so that an image step is within a preset tolerable value, based on the information about integration dose of ray for the first imaging operation.
