A display driver comprises: digital gamma circuitry configured to generate a voltage data based on an image data for a pixel of interest; compensating circuitry configured to calculate a total current of the display panel; and correction circuitry. The correction circuitry is configured to correct the voltage data, based on the calculated total current.

Compensation technology for display panel

An image processing apparatus includes a reference value calculating section configured to generate a value that is a weighted average of values of R data, G data, and B data of original RGB data as a reference value. Regarding each of color data such as the R data, the G data, and the B data, a value is calculated that is coincident with a value obtained by adding the value of the color data of the original RGB data to a product of a difference obtained by subtracting the reference value from the value of the color data of the original RGB data and a predetermined coefficient, as a value of the color data of RGB data after saturation expansion.
