    • An image processing apparatus capable of eliminating noise from a digital image with edges maintained intact. The apparatus includes: an input means for accepting a digital image; a noise amount determination unit for determining the amount of noise in the digital image, and setting noise elimination power; a noise suppression unit for eliminating the noise from the digital image based on the noise elimination power; and an output means for outputting the noise suppressed digital image. The noise amount determination unit includes: a chrominance component separation unit for separating chrominance components from the digital image; a frequency transformation unit for transforming each of the separated chrominance components into the frequency domain; and a noise elimination power setting unit for calculating the amount of noise in each chrominance component transformed into the frequency domain, and setting the noise elimination power according the calculated amounts of noise.

    • An image processing device including a storage section, a parallel processing controller, a sequential processing controller, and a selection section which selectively operates the two control sections. The parallel processing controller connects one or more of the image processing modules such that first buffer modules are connected at least one of preceding and following each image processing module, to formulate a first image processing section, and controls such that individual image processing modules perform image processing in parallel with one another. The first buffer modules perform exclusive access control. The sequential processing controller connects one or more of the image processing modules such that second buffer modules are connected at least one of preceding and following each image processing module, to formulate a second image processing section, and controls such that the individual image processing modules perform image processing sequentially. The second buffer modules do not perform exclusive access control.
