PURPOSE:To improve quality of image and an S/N ratio in the displaying of an image data as animation image by a method wherein an output from a table memory and an old data from a memory are inputted and a cumulative addition is performed by adding the output data from the table memory to the old data to send out the results to an image display section. CONSTITUTION:A buffer memory 4 inputs an image data measured with a measuring section 2 to be stored temporarily. An subtracter 5 inputs the old data of the previous time phase read out of the buffer memory 4 and new data of the following time phase to be outputted sequentially from the measuring section 2 to determine a difference therebetween over the image data belonging to the same location. A table function is stored in the table memory 6. An adder 7 inputs the output data from the table memory 6 and the old data from the buffer memory 4 to perform a cumulative addition by adding the output data from the table memory 6 to the old data. An output data from the adder 7 is sent out to an image display section 3 while being stored into the buffer memory 4. |
