    Abstract: An image processing apparatus processes noise from a defective pixel in image data generated by an image sensor including plural pixels, and plural read-out circuits that read out the signal. The apparatus includes an acquisition unit that obtains the image data and position information of the defective pixel; a defective pixel correction unit that corrects the signal from the defective pixel included in the image data, based on the position information; a low saturation pixel correction unit that corrects a signal from a low saturation pixel included in the image data where the signal from the defective pixel has been corrected, the low saturation pixel having a saturation level lower than the other pixels, based on a preliminarily calculated saturation level of the plural pixels; and a saturation level calculation unit that calculates the saturation level of the defective pixel corrected by the defective pixel correction unit.

    Abstract: An imaging apparatus includes an imaging unit, a random seed generating unit, a pseudo-random number generating unit, and a special image processing unit. The imaging unit photographs a subject to obtain image data. The random seed generating unit generates a random seed to decide a pseudo-random number sequence. The pseudo-random number generating unit generates a pseudo-random number in accordance with the generated random seed. The special image processing unit performs special image processing to apply a special effect to the image data based on the generated pseudo-random number. The random seed is decided during photography.
