An image processing device includes a detector for detecting a linear-interpolation-applicable area and an expansion corrector for performing a gradation expanding process on the linear-interpolation-applicable area detected by the detector. When a detector 11 detects a linear-interpolation-applicable area, if the gradation values of pixels preceding and following a pixel where a gradation change in a predetermined range is detected are the same as each other, then the detector judges the gradation change as being caused by a noise or the like, and regards the gradation value of the pixel where the gradation change is detected as the gradation values of pixels preceding and following the pixel. |
