METHOD FOR IMPROVING SHARPNESS OF COLORS, DEVICE FOR CAPTURING OR REPRODUCING IMAGE, DIGITAL IMAGE CAPTURE DEVICE, DIGITAL IMAGE, AND SENSOR FOR DIGITAL IMAGE CAPTURE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for improving sharpness of colors which enables digital restoration of focusing without a mobile unit and without delay.SOLUTION: The invention concerns a method for activating a function by using a measurement taken from at least one digital image (10), which has at least two colors (195, 196) and originates from an image capture device. The method includes: measuring the relative sharpness between at least two colors in at least one region R of the image (190); and controlling at least one action depending on the measured relative sharpness (191).
