1. A method of processing a 3D image signal in a portable terminal apparatus equipped with hardware means having a display panel, a kernel layer directly controlling the hardware means, an application/middleware layer controlling the kernel layer to display a motion picture through the hardware means, a 3D image being displayed on the display panel along with a plane image, the method comprising:
generating one or more plane image surfaces from the application/middleware layer and storing the one or more plane image surfaces in a first frame buffer; decoding an encoded image signal under the application/middleware layer and restoring a YUV image signal to represent a stereoscopic image pair; converting the YUV image signal into an RGB image signal at the kernel layer; determining whether the RGB image signal is a 2D image signal or a 3D image signal at the kernel layer; when the RGB image signal is the 2D image signal, transferring the RGB image signal to an RGB buffer; when the RGB image signal is the 3D image signal, transferring the RGB image signal to a mix buffer, mixing left and right images of the RGB image signal at the kernel layer, wherein the left and right images being alternately arranged in the unit of vertical lines of pixels, and storing a mixed stereoscopic image signal in the RGB buffer; transferring the RGB signal in the RGB buffer to a second frame buffer dedicated to motion playback; and composing signals, which are stored in the first and second frame buffers, to create a composite signal in hardware by overlaying at the kernel layer and transferring the composite signal to the display panel, wherein the display panel displays a stereoscopic image along with a normal plane image. |
