Patent ID: 8643633

Claim:
An image processing apparatus comprising: a driving unit adapted to divide one frame of image data into a high-frequency component emphasized subframe and a low-frequency component subframe and drive the high-frequency component emphasized subframe and the low-frequency component subframe; a polarity inversion unit adapted to output the high-frequency component emphasized subframe and the low-frequency component subframe following the high-frequency component emphasized subframe at opposite polarities; a control unit adapted to output the image data while switching a phase mode between a first mode of driving the high-frequency component emphasized subframe at positive polarity and the low-frequency component subframe at negative polarity and a second mode of driving the high-frequency component emphasized subframe at negative polarity and the low-frequency component subframe at positive polarity; and a clocking unit adapted to measure an elapse of time; wherein when said clocking unit has measured an elapse of a predetermined time, said control unit switches the phase mode between the first mode and the second mode.
