PURPOSE:To improve probability to perform regular reading and/or image processing correctly by providing a neural network setting correct/incorrect information inputted from an input means as a teacher signal. CONSTITUTION:Algorithm to find a reading condition suitable for each photographic condition, respectively, and the neural network different from respective condition to decide the correctness/incorrectness of the reading condition are stored in a computer system 20. When the completion of adjustment for the density and contrast of a visible image is inputted from a keyboard 43, a corresponding neural network is readout, and the (learning) of the network is performed by setting a pre-read image signal Sp thinned uniformly extending over the entire plane of an X-ray image to reduce the number of input points and the reading condition automatically obtained as input signals, and the correct/incorrect information of the reading condition obtd. by the adjustment of a visible image by an operator as the teach signal. In such a way, it is possible to decide the correctness/incorrectness of the reading condition correctly. |
