Patent number: 9530176Abstract: 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.Type: GrantFiled: February 15, 2013Date of Patent: December 27, 2016Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ji-won Kim, Young-hun Choi
