Abstract
A two dimensional image production method by using a solid-state image sensing device, wherein the solid-state sensing device comprises a picture element producing part where electric charges generated by way of photo-electric conversion when receiving exposure is stored as charge signals, and a dark current measuring part where a dark current is stored without receiving exposure. The method comprising the steps of: preparing and storing in advance the output ratio data for a fixed exposure time between dark current component of each pixel element or each pixel element column in the picture element producing part and that of a specified pixel element or a specified pixel element column in the dark current measuring part, and producing sequentially pixel datum removed a dark current component while performing radiography, by executing a predetermined arithmetic operation for the signals of the electric charges outputted from the picture element producing part depending on the output ratio data.
