Liquid crystal device, image processing device, image display apparatus with these devices, signal input method, and image processing method

An image processing device that generates a display signal, which is to be input into a liquid crystal device having multiple pixels, the image processing device comprising:

• a video signal conversion circuit that converts an input video signal and generates multiple pixel signals, which are to be given to the multiple pixels of the liquid crystal device;
• and
• a display signal generation circuit that combines the multiple pixel signals with a predetermined signal, which is used for generating a common signal to be commonly supplied to the multiple pixels, and thereby generates one display signal.

A method of inputting a predetermined signal into a liquid crystal device that has multiple pixels and receives a display signal including multiple pixel signals, which are to be given to the multiple pixels, the predetermined signal being used for generating a common signal to be commonly supplied to the multiple pixels,

• the method comprising the step of:
• embedding the predetermined signal into a predetermined period that does not include the pixel signals in the display signal and inputting the embedded predetermined signal as part of the display signal.
