IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, SOLID-STATE IMAGING DEVICE, AND ELECTRONIC APPARATUS

摘要

An image processing apparatus includes: a target position selecting unit to select a pixel position on an input image, as a target position; a candidate line setting unit to set two or more sets of candidate lines including a pixel with a value, in the vicinity of the target position; a weighted-value calculating unit to calculate a weighted value that corresponds to a degree of expectation that the target position and the pixel position on the candidate line are on the same pattern; a direction classifying unit to selectively determine a set of candidate lines that are close to a direction of a pattern of the target position in accordance with the weighted value of each pixel on the candidate lines; and a first interpolated-value calculating unit to calculate a pixel value of the target position in accordance with the weighted value of each pixel on the candidate lines.

1. An image processing apparatus, comprising:
a target position selecting unit configured to select a pixel position on an input image, as a target position in which a pixel value is interpolated; a candidate line setting unit configured to set two or more sets of candidate lines including a pixel with a value, in the vicinity of the target position; a weighted-value calculating unit configured to calculate a weighted value that corresponds to a degree of expectation that the target position and the pixel position on the candidate line are on the same pattern; a direction classifying unit configured to selectively determine a set of candidate lines that are close to a direction of a pattern of the target position in accordance with the weighted value of each pixel on the candidate lines; and a first interpolated-value calculating unit configured to calculate a pixel value of the target position in accordance with the weighted value of each pixel on the candidate lines.
