Abstract:
1. An image data processing method for sharpening a captured image using a focus function produced based on a focused image and a defocused image of a subject, comprising: defining a first transformation equation that includes a DetailedFocus function, to change the pixel values of a defocused image into the pixel values of a focused image using the coordinates of the defocused image and the coordinates of the focused image as arguments; calculating a DetailedFocus function as the optimal solution for the first transformation equation by using the pixel values of the focused image and the defocused image as educational data; performing an important point selection process for extracting a predetermined number of important points on the DetailedFocus function; defining a second transformation equation that includes a SmartFocus function, to change the pixel values of a defocused image into the pixel values of a focused image based on the important points using the coordinates of the defocused image and the coordinates of the focused image as arguments, after the important point selection process; calculating a SmartFocus function as the optimal solution for the second transformation equation by using the pixel values of the focused image and the defocused image as educational data; and producing a focused image from a defocused image captured by an imaging device using the SmartFocus function as said focus function.
