Abstract
The present disclosure allows reducing the variation of the luminance depending on the types of images and improving image quality by calculating a plurality of representative values, representing the luminance of pixels so that the types of images can be distinguished, calculating a weight using such representative values, and compensating image data according to the weight.
Claims20
A method of processing image data, the method comprising:
- calculating at least one representative value representing luminance of pixels disposed on a panel;
- calculating a weight by using the at least one representative value;
- calculating a reflection rate of the weight by analyzing a chroma of image data;
- generating converted image data by applying the weight to the image data at the reflection rate;
- and
- transmitting the converted image data to a panel driving device for driving the panel.

An image data processing device comprising:
- a representative value calculating circuit configured to calculate at least one representative value representing luminance of pixels disposed on a panel;
- a weight calculating circuit configured to calculate a weight by using the at least one representative value;
- a weight applying circuit configured to calculate a reflection rate of the weight by analyzing a chroma of image data and to apply the weight to the image data at the reflection rate to generate converted image data;
- and
- an image data transmitting circuit to transmit the converted image data to a panel driving device to drive the panel.
