IMAGE PROCESSING DEVICE, DISPLAY DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM

摘要

An image processing device includes a detection unit for detecting a linear interpolation application region and an extension correction unit for gradation-extending the linear interpolation application region detected by the detection unit. When detecting a linear interpolation application region, the detection unit (11) judges that a gradation change is caused by a noise when gradation values of the pixels before and after the pixels in a predetermined range in which a gradation change has been detected have the same gradation value and assumes that the gradation value of the pixels in which a gradation value has been detected is the gradation value of the preceding and following pixels.
