1. An image data processing method comprising at least an image processor, performing:
extracting a depth map from an input image, wherein the input image is comprised by a plurality of pixel data each with a corresponding depth value represented by a grayscale; using the plurality of pixel data which comprise the input image, mapping in a 1:1 linear correspondence, the input image to an output image to generate an initial depth map with an origin being a common starting minimum depth value, wherein each of the plurality of pixel data having the corresponding depth value represented by the grayscale, and the initial depth map comprises an x-axis corresponding to the depth values represented by the grayscale of the input image, and a y-axis corresponding to depth values represented by the grayscale of the output image; separating along the x-axis of the input image in the initial depth map, into a foreground area, a background area and a gray grayscale portion corresponding to the depth values between the foreground area and the background area based on the represented grayscales of the initial depth map; modulating by changing a grayscale of only a maximum depth value of the input image without changing the common starting minimum depth value at the origin to produce a modified output image for a modified depth map, wherein the modified output image corresponds to a lower maximum depth value represented by the grayscale in the modified depth map; modulating along the x-axis of the modified depth map, respective depth values represented by the grayscale in the foreground area, the background area and the gray grayscale portion of the input image to produce corresponding depth values represented by the grayscale for a final output image of a final depth map, such that in the final output image: changes to the depth values represented by the grayscale along the y-axis corresponding to the gray grayscale portion of the input image, being faster than changes to the depth values represented by the grayscale along the y-axis corresponding to both the foreground area and the background area of the input image on the final depth map, respectively, wherein the output image corresponds to a same lower maximum depth value without changing the common starting minimum depth value at the origin; and displaying the final modified output image as the stereoscopic image according to the final depth map. |
