Abstract
An image data processing apparatus includes an encoding unit, a storage unit, a decoding unit and a Digital-to-Analog (D/A) converter. The encoding unit receives image data, compares (2n−1)th pixel data with (2n)th pixel data, and creates a header value, an encoding value and a reference value, which are used to encode the pixel data. The storage unit is connected to the encoding unit, and stores the header value, the encoding value and the reference value, which are created by the encoding unit. The decoding unit is connected to the storage unit, and restores the (2n−1)th pixel data and the (2n)th pixel data using the header value, the encoding value and the reference value. The D/A converter is connected to the decoding unit, converts the restored image data into analog signals, and outputs the analog signals.
