Abstract: An image signal processor includes a first sharpening filter configured to perform a first filtering operation on a raw data output from an external image device to output first sharpness data. A second sharpening filter is configured to perform a second filtering operation on the raw data in parallel with the first filtering operation to output second sharpness data. An edge determiner is configured to determine an edge strength of an image corresponding to the raw data based on the raw data and to adjust a first weight and a second weight based on the determined edge strength. A combiner configured to combine first weight data in which the adjusted first weight is reflected in the first sharpness data and second weight data in which the adjusted second weight is reflected in the second sharpness data to generate output data.
