An image processing apparatus and image processing method thereof are disclosed. The image processing apparatus includes a first image processor which includes a memory, performs a first signal processing on image data, and stores the first signal processed image data in the memory; a second image processor which directly accesses the memory and receives the stored image data, and performs a second signal processing on the received image data; and an image outputter which outputs the image data on which the second signal processing has been performed. Accordingly, only actual image data area is received, reducing data transmission volume, reducing signal transmission lines, securing CPU resources, and improving timing errors. In addition, it is possible to remove an image transmitter such as an additional low voltage differential signaling (LVDS) block, making the image processing apparatus thinner and smaller.

A display apparatus and a control method thereof are provided. The display apparatus is coupled to a video signal supply source through at least one connector. The display apparatus includes: a main storage unit which stores extended display identification data (EDID) therein corresponding to the at least one connector; a temporary storage unit which loads the EDID thereto from the main storage unit; and a controller which loads the EDID stored in the main storage unit to the temporary storage unit if power is supplied, and controls to transmit the EDID corresponding to an EDID requesting signal, among the EDID loaded to the temporary storage unit, through the at least one connector if the EDID requesting signal is received through the at least one connector.

Display apparatus and control method thereof

A method of setting time information of a display apparatus is provided. The method includes: receiving a Turn-on signal from a remote controller; receiving time information from the remote controller in response to a determination that resetting the time information is necessary; and setting time information of the display apparatus based on the received time information.

Method for setting time of display apparatus, method for setting time of display apparatus by remote controller, display apparatus and remote controller

Methods and apparatuses for processing a video signal are provided, in which a video signal for an interlaced scanning mode is received that has a first field and a second field. Further, a determination is performed as to whether the first field and the second field are inverted with respect to each other, and the first field and the second field are recovered if the first field and the second field are determined to be inverted with respect to each other. Thus, a video signal can be generated for a progressive scanning mode on the basis of the recovered first and second fields. Thus, an odd field can be correctly distinguished from an even field, which are included in a video signal for an interlaced scanning mode.

Method and apparatus for processing video signal

A display apparatus including an image receiver receiving an image signal and a display displaying the image signal. The display apparatus includes a user selector, an image signal processor to process at least one image delay decrease mode to decrease a processing time of the image signal and a controller to control the image signal processor to process the image signal according to the selected image delay decrease mode if an image delay decrease mode is selected through the user selector.
