Image processing apparatus and method, program, and recording medium |
摘要 |
An image processing apparatus includes a computation unit that determines an interpolation process starting point and gradient on the basis of a change point at which a difference between pixel values of adjacent pixels of an image signal is greater than zero and is less than or equal to a predetermined threshold value, wherein a position of a pixel scanned earlier or later than the change point by substantially one-half a continuous width of pixels having an identical grayscale value is set as the starting point and the gradient is determined based on a difference between pixel values before and after the change point and the continuous width, and a conversion unit that converts pixel values of the image signal on the basis of the determined starting point and gradient so that a grayscale change from the interpolation process starting point in the image signal corresponds to the gradient. |
