Claim One:
1. An image processing method comprising: obtaining N number of image data regarding a same object, each of the N number of image data comprising a plurality of pixels; removing noise data of N number of pixel data regarding pixels in a same location, from the N number of image data; and generating an image of the object using the N umber of image data excluding the noise data; wherein the noise data is data with a frequency being at least a cutoff frequency or greater than that of the rest of the N pixel data excluding the noise data, wherein the removing noise data removes the noise data using a time axis low band pass filter, and wherein the low band pass filter comprises a circuit configured to satisfy a transfer function shown below: H ⁡ ( j ⁢ ⁢ ω ) = 1 1 - ( ω ω n ) 2 + j ⁢ ⁢ ω Q ⁢ ⁢ ω n where Q is a quality factor, and ω n is a natural frequency.
