Image processing apparatus, image processing method, and computer-readable storage medium for calculating a depth value of a subject in an image |
摘要 |
An image processing apparatus includes: means for extracting, for each pixel of an image, a high-frequency component as focus information from a brightness signal for a neighboring pixel; means for integrating, for each pixel, the focus information on the neighboring pixel; means for replacing the focus information on each pixel with a value obtained using the focus information on the neighboring pixel greater than the focus information on that pixel to generate dark area focus information; means for integrating the brightness signals of each pixel and the neighboring pixel to extract an illumination component; means for calculating a depth value of each pixel using a coefficient based on the illumination component; means for normalizing the depth value of each pixel; means for controlling the normalized depth value using a tone curve; means for detecting a saturation of each pixel; and means for controlling the controlled depth value using the saturation. |
