IMAGE FORMING APPARATUS, IMAGE FORMING SYSTEM, METHOD OF CONTROLLING SAID APPARATUS AND SYSTEM, AND PROGRAMME Russian patent published in 2014 - IPC G06T1/00 H04N5/32 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to an image forming apparatus. The result is achieved due to that the image forming apparatus includes a control unit and a detector which includes a plurality of pixels and which performs an image capturing operation for outputting image data corresponding to emitted radiation or light. The image capturing operation includes a first image capturing operation in which the detector is scanned in a first scanning region which corresponds to part of the plurality of pixels to output image data in the first scanning region, and a second image capturing operation in which the detector is canned in a second scanning region larger than the first scanning region to output image data in the second scanning region. The control unit prompts the detector to perform an initialisation operation for initialising a conversion element during a period between the first image capturing operation and the second image capturing operation in accordance with the switch from the first scanning region to the second scanning region.

EFFECT: design of a device capable of reducing the difference in level which might arise in a captured image and which depends on the scanning region to prevent considerable deterioration of image quality.
