Abstract: An image device and an image processing integrated circuit (IC) of the image device are provided. The image device includes a camera module, a display panel, a central processing IC, and an image processing IC. Based on a control of the central processing IC, the image processing IC decides whether to pre-process an output of the camera module and provide a pre-processed result to the central processing IC, or provide the output of the camera module directly to the central processing IC. Based on the control of the central processing IC, the image processing IC decides whether to post-process an output of the central processing IC and provide a post-processed result to the display panel, or provide the output of the central processing IC directly to the display panel.

Abstract: An image processing circuit and a method thereof are provided herein. The image processing circuit has a first scaling circuit, one or more line buffers, a first sharpness circuit, a second scaling circuit, and a second sharpness circuit. The first scaling circuit enlarges an input image along a first direction to generate a first enlarged image. The one or more line buffers temporarily store the pixel values of a plurality of pixel rows of the first enlarged image. The first sharpness circuit vertically sharpens the first enlarged image to generate a first sharpened image. The second scaling circuit enlarges the first sharpened image along a second direction to generate a second enlarged image. The second sharpness circuit horizontally sharpens the second enlarged image to generate a second sharpened image. Accordingly, it is possible to use the one or more line buffers having shorter data lengths to perform the vertical sharpening.
