摘要： A detecting unit detects an object in an input image. A depth map generating unit selects a depth template corresponding to a type of the object and places a selected depth template on a depth map in accordance with a position of the object to generate the depth map having a depth value for each pixel. A correcting unit calculates a weight of at least one interested pixel and a weight of a peripheral pixel based on a relationship between pixel values to the interested pixel and the peripheral pixel and corrects the depth value of the interested pixel based on a weighted sum of the respective depth values corresponding to the interested pixel and the peripheral pixel. An image generating unit generates parallax images based on the corrected depth map and the input image.

摘要： An image processing apparatus calculates an absolute difference in pixel values between each pixel (target pixel) of the image and each of neighboring pixels of the target pixel, and a sum of the absolute differences with respect to the target pixel, calculates a threshold using the sum of the absolute differences with respect to the target pixel and a weight previously determined, the threshold being used as a reference for determining whether the pixel values of the neighboring pixels are used in a smoothing process for the target pixel, and performing a smoothing process by means of an edge-preserving smoothing filter, based on whether the absolute difference in pixel values between the target pixel and each of the neighboring pixels of the target pixel exceeds the threshold.
