1. A method for activating a function by using a measurement taken from at least one digital image having at least two colours and originating from an image-capturing apparatus, wherein:
- the relative sharpness is measured between at least two colours on at least one region R of the image, andat least one function is activated depending on the measured relative sharpness.

Abstract
The invention concerns a method for activating a function by using a measurement taken from at least one digital image (10) having at least two colours (195, 196) and originating from an image-capturing apparatus.
According to such method:
- the relative sharpness is measured (190) between at least two colours in at least one region R of the image, and
- at least one action is controlled (191) depending on the measured relative sharpness.

55. A method for improving the sharpness of at least one colour of a digital image, notably stemming from an image-capturing device, comprising the steps of
selecting from among the colours at least one colour referred to as “ - sharp colour”
,reflecting the sharpness of the sharp colour onto at least one other improved colour, so that the improved colour represents increased sharpness. - View Dependent Claims (56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
- sharp colour”
- 71. A sensor for a digital image-capturing apparatus comprising pixels, mainly serving to generate the digital image, and other pixels, mainly serving to measure the relative sharpness between at least two colours on at least one region R of the image.
- 75. A digital image-capturing apparatus comprising a sensor representing, on the one hand, spectral response pixels, mainly within the field visible to the human eye, and additional pixels having a spectral response, mainly beyond the spectre visible to the human eye, on the other, the sharpness of the part of the image stemming from these additional pixels exceeding, within at least one range of distances between the capturing apparatus and the imaged scene, the sharpness of the part of the image provided by the pixels whose spectral response is mainly within the field visible to the human eye.
