Display apparatus, connectable external peripheral device and method of displaying an image

摘要

A display apparatus, a connectable external peripheral device and a method of displaying an image are disclosed. The display apparatus includes a display unit; an image processor which first processes an image signal according to a preset first image processing operation, and secondly processes the first processed image signal processed according to the first image processing operation, and outputs the processed image signal to the display unit. The display apparatus further includes a peripheral device connector, to which an external peripheral device is connected that processes the image signal processed by the first image processing operation. The second image processing operation is performed in the external peripheral device. The image processor transmitting to the external peripheral device the first processed image signal in response to the external peripheral device being connected to the peripheral device connector.

主权项

1. A display apparatus comprising:
a display unit; a first image processor of the display apparatus configured to perform a first image processing operation on an image signal to output a first image signal to an external peripheral device; a peripheral device connector configured to be connected to the external peripheral device having a graphic signal generator which is configured to generate a graphic signal of a graphical user interface (GUI) menu corresponding to a user input; and a processor of the display apparatus configured to, in response to a user command being transmitted to the external peripheral device through the peripheral device connector or being input by a user in the external peripheral device:
(1) receive, from the external peripheral device, a graphic signal of the GUI menu generated by the graphic signal generator of the external peripheral device based on the user command, the user command being a user command for generating the graphic signal of the GUI menu, and(2) control the display unit to display an image generated by synthesizing the first image signal and the graphic signal of the GUI menu received from the external peripheral device, the synthesizing being performed by either the display apparatus or the external peripheral device.
