A content providing apparatus is disclosed. The content providing apparatus comprises: a communication unit for communicating with an external apparatus; an image processing unit for generating a compressed image by image-processing an input original image; and a control unit for controlling the communication unit to divide the original image into one or more regions based on the image quality, to obtain characteristic information for each region from the respective regions, and to transmit the obtained characteristic information for each region together with the compressed image to the external apparatus. As the result, the display apparatus may perform image quality improvement operation so that the image quality is close to the original quality level by extracting information required for improving the image quality and transmitting the same together with a compressed image in production and encoding steps before transmitting the image.

Content providing apparatus, display apparatus, and control method therefor

A method of driving a display panel including a plurality of pixels including a red (R), green (G), blue (B), and white (W) sub-pixels is provided. The method includes receiving image data, converting RGB data included in the image data into RGBW data, and driving the display panel based on the converted RGBW data. The converting includes converting the RGB data into YCbCr data and determining a W value of the RGBW data based on a Y value of the converted YCbCr data.

Display apparatus and display panel driving method thereof

An image processing method includes dividing an image into one or more regions, obtaining a region-based histogram smoothing function for processing the image to have a uniform number of pixels based on a pixel value for each of the divided region, obtaining a global smoothing function for an entire image using the obtained region-based histogram smoothing function, obtaining a local smoothing function for each pixel of the image using the region-based histogram smoothing function applied to a region in a block, and obtaining a sum of weight values of the global smoothing function and the local smoothing function, and determining the pixel value, based on the obtained sum of the weight values.
