The invention relates to a digitizing apparatus (1) for forming (digitizing) a digital, electrical image of a subject (3). The digitizing apparatus (1) comprises a light sensor (4) consisting of one or several photosensitive picture elements (P1, P2, ..., P10) and to which the image of the subject (3) is arranged to be directed in one or several parts, the image being divided into pixels. Each picture element (P1, P2, ..., P10) to be used in digitizing is arranged to conduct a photoelectric conversion to generate a signal proportional to the lightness of the pixel directed to the picture element. At least one pixel to be digitized is arranged to be subjected to at least two conversions. In at least two different conversions, the quantity of light to be directed during the conversion of said pixel to the picture element conducting the conversion is arranged to be adjustable, wherein in at least two conversions, the quantities of light are unequal. |
