Abstract: An image processing device comprises an image sensor including unit groups comprising a reference group and a conversion group each including pixels and color filters, and is configured to generate image data using the pixels, and an image signal processor which is configured to calculate a hash of the image data, and to select a filter corresponding to the hash to perform filtering, wherein the image signal processor includes a pixel index converter which is configured to convert indexes of the pixels based on a positional relationship between the pixels, a pixel property converter which is configured to convert the properties of the pixels and to convert the hash before conversion, and a filter coefficient converter which is configured to convert filter coefficients of the pixels based on the respective converted pixel index and the respective converted pixel property.
