Abstract
An image processing apparatus includes the following. A hardware processor decomposes a signal value of input image data into band-limited signals having different frequency bands from each other. A storage stores pieces of preset data. Each of the pieces of preset data comprises tables to associate frequency with a response and to prescribe different response properties from each other. The hardware processor selects a piece of preset data from the pieces of preset data stored in the storage, converts the decomposed band-limited signals on a basis of tables in the selected piece of preset data, reconstructs the converted band-limited signals into enhanced image data, and generates a frequency-enhanced image through addition of the enhanced image data which is multiplied by a predetermined enhancement coefficient to the input image data.
