An encoding method includes selecting a run detection method in accordance with characteristics of image data, generating a run value by detecting a run that is repeated in the image data in accordance with the selected run detection method, generating run count bits by counting the number of repetitions of the detected run, and performing a run-length encoding using the detected run values and the run count bits. The run detection method includes a coefficient run detection method that detects a run based on pixel values, a pattern run detection method that detects the run based on whether the pixel blocks have a specified pattern, a difference run detection method that detects the run based on a difference value between two successive pixel values, and a residual run detection method that detects the run based on an error value that is a difference value between an actual pixel value and a predicted value.
摘要:
A foldable display device is designed so that a junction between at least two display panels connected to each other is not visibly seen. The display device displays an image on a plurality of display panels that are connected together. Pixels near the junction between every two adjacent display panels of the at least two display panels are smaller and have a higher brightness than the other pixels.

Provided are a terminal and method for distinguishing between email recipients using a specific identifier. According to the inventive terminal and method, when email is desired to be sent to several recipients, it is possible to set an individual transmission configuration for each recipient and transmit the email in different formats depending on the recipients. Thus, a large-sized file is prevented from being unnecessarily created or transferred, thereby reducing unnecessary traffic. In addition, it is possible to prevent the storage space of a mobile device from being wasted due to receiving an unwanted attachment file.
