Abstract: A method of searching for a synthesis condition includes: designating N+1 vertices separated from each other, each having an experimental condition corresponding to a designated location in an N-dimensional space including N axes, each corresponding to a different experimental variable; performing a reflection operation for moving the first vertex determined based on experimental values corresponding to the vertices to an opposite side of an N−1 dimensional simplex based on a center point of the N−1 dimensional simplex corresponding to remaining N vertices; performing a projection operation for moving again the first vertex back to a location where a movement path of the first vertex and a predetermined boundary of the N-dimensional space cross each other when the first vertex is moved outside the predetermined boundary; and determining, as the synthesis condition, an experimental condition of a final vertex determined based on experimental values corresponding to vertices after the projection operation.

Abstract: An image processing method acquires an image, restores a saturated region in which a pixel in the image has a first reference value based on a first illuminance component of the image, enhances a dark region in which a value of a pixel in the image is less than a second reference value based on the restored saturated region and the first illuminance component, and outputs a dark region-enhanced image.
