A display panel driver includes: a correction calculation section which performs correction calculations on input image data to generate saturation-enhanced output image data and a drive circuitry driving the display panel in response to the output image data and a starting point control section. The correction calculation section generates red (R) data, green (G) data and blue (B) data of the output image data by performing the correction calculations on R data, G data and B data of the input image data, respectively. The starting point control section controls the positions of starting points of the input-output curves of the correction calculations.
