<P>PROBLEM TO BE SOLVED: To provide an apparatus and a system capable of performing a suitable offset correction for the variation in the offset, while meeting a demand for reducing an exposure preparation period. <P>SOLUTION: The imaging apparatus includes: a detector 104 in which a plurality of pixels each including a conversion element 201 are arranged in a matrix form, wherein the detector 104 performs an exposure imaging operation for outputting exposure image data, a correction imaging operation for outputting correction image data, an exposure preparation operation for stabilizing a characteristic of the conversion element 201 during a time between the start of application of a bias to the conversion element 201 and the exposure imaging operation, and a correction imaging preparation operation including an initialization operation for initializing the conversion element 201 between the exposure imaging operation and the correction imaging operation; a correction unit configured to correct the exposure image data using the correction image data; and a control unit, wherein the control unit performs the initialization operation based on a determined number of times according to the amount of variation in offset at the time of shifting from the exposure preparation operation to the exposure imaging operation, and controls the operation of the detector 104. <P>COPYRIGHT: (C)2012,JPO&INPIT |
