Abstract: A data processing method for audio playback, an audio playing method, and an audio player are provided. The data processing method for audio playback in an application processor includes: reading n-th audio data (where n is a natural number of 1 or more) which is an n-th part of one or more audio files, which is selected in accordance with a user command, from a storage unit; decoding the read n-th audio data; and storing the decoded n-th audio data in an m-th buffer of an audio playing unit at a subsequent stage (where m is equal to n mode M, M is the number of buffers in the audio playing unit, and m is equal to M when the remainder is 0). Accordingly, since the application processor need not always be activated to play audio, it is possible to reduce the power consumption of a battery.

Abstract: Device and method of correcting a distortion occurring at the time of displaying a high-resolution image on a low-resolution display unit are provided. The image distortion correcting method includes the steps of: analyzing color levels of all pixels of an input original image; determining a variation of the color levels depending on positions of the pixels; adjusting the variation of the color levels in a region where the variation departs from a predetermined threshold value; correcting the color levels of the pixels in accordance with the adjusted variation; and outputting the corrected image. Accordingly, it is possible to correct the image distortion occurring at the time of displaying an image input from an image sensor on a display module.
