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.

An image processing apparatus for converting a low-resolution image into a high-resolution image. When a target pixel is located in an edge region, evaluation values relating to similarity between the target pixel and candidate pixels along a proximate line adjacent to the target pixel are calculated. A distribution of the evaluation values along each of the proximate lines by using an approximate function. Based on the value of the approximate function, a corresponding position of the target pixel on each of the proximate lines is calculated. A pixel value of the new pixel based on the pixel value of the target pixel and a distance between the new pixel and the specified line segments.
