Patent ID: 8254523

Claim:
An imaging apparatus having a X-ray detector for detecting transmissive X-rays passing through a subject irradiated from the imaging apparatus and an image display unit for displaying the detected image by the X-ray detector, comprising: a first display magnification calculation unit for receiving information of the detected image size which is a size of a reading area of the detector, a binning condition and a display frame size of the image display unit, and thereby calculating a first display magnification so as to maximize a display area of the detected image corresponding to the display frame size and not to exceed the size of the display frame size; a second display magnification calculation unit for temporarily changing the received binning condition, and by using the temporarily changed binning condition and the received detected image size, calculating a second display magnification so as to maximize a display area of the detected image corresponding to the display frame size and not to exceed the size of the display frame size; and a selection unit for selecting the second display magnification and the temporarily change binning condition if the second display magnification is closer to one when comparing the first display magnification and the second display magnification with one, and selecting the first display magnification and the received binning condition if the first display magnification is closer to one when comparing the first display magnification and the second display magnification with one.
