Claim One:
1. An image processing equipment, comprising: an image reducing part generating a reduced image of an obtained image being read; a reduced image storing part storing the reduced image being generated; an image storing part storing the obtained image in parallel with a processing by the image reducing part; a low-frequency noise component extracting part sequentially extracting a low-frequency noise component of each of pixels included in the obtained image based on pixel data of pixels included in a predetermined area of the reduced image at a portion corresponding to each of the pixels included in the obtained image; and a noise subtracting part sequentially reading pixel data corresponding to one of the obtained image stored in the image storing part and an adjusted image generated from the obtained image in synchronization with an output of the low-frequency noise component being extracted, and sequentially subtracting the low-frequency noise component from the pixel data being read, wherein respective processings by the low-frequency noise component extracting part and the noise subtracting part are pipelined.
