1. An image processing apparatus comprising: an up-sampling section configured to carry out up-sampling processing to increase the number of pixels composing an input image having a first resolution to the number of pixels composing an image having a second resolution higher than said first resolution in order to generate an up-sampled image; a motion-compensated image generation section configured to generate a motion-compensated image as a result of correction processing to adjust a referenced image having said second resolution to a photographing-object position on said up-sampled image by making use of information on a difference between said up-sampled image and said referenced image; a blending processing section configured to generate an intermediate blended image as a result of blending processing to blend said up-sampled image with said referenced image by comparing said up-sampled image with said motion-compensated image for every image area unit and by setting a blending coefficient of said referenced image at a such a value that, the higher the degree of pixel-value matching for an image area unit, the higher the value at which said blending coefficient is set for said image area unit; and an output-image generation section configured to receive and process said intermediate blended image as well as said up-sampled image in order to generate an output blended image obtained by blending a super-resolution processing-result image obtained as a result of super-resolution processing carried out as processing to increase the resolution of said input image with a noise-reduction processing-result image obtained as a result of noise reduction processing carried out to reduce noises of said input image.
