Method for measuring radiation by means of an electronic terminal having a digital camera

摘要

The invention relates to a method for operating an electronic terminal (1.1-1.4) comprising an integrated image sensor (2.1-2.4) that has a large number of pixels, in particular for a mobile telephone. According to the invention, a dosage value of ionizing radiation striking the image sensor is determined by means of the image sensor (2.1-2.4). The invention further relates to a terminal that operates accordingly (e.g. a smart phone having a corresponding application program).

1. An operating method for an electronic terminal unit with an image sensor with a plurality of image elements, said method comprising:
a) determining a dosage value of ionizing radiation impinging on the image sensor; b) measuring an image matrix through the image sensor, wherein the image matrix for the individual image elements of the image sensor respectively contains an associated image element and the individual image elements of the image matrix are respectively assigned to an electric output signal associated with the image element of the image sensor; c) statistical evaluation of the image matrix and calculation of the dosage value in a framework of this statistical evaluation; d) calculating a counting matrix from the image matrix, wherein the counting matrix for the individual image elements of the image matrix respectively contains an associated counter; and e) incrementing individual counters of the counting matrix when an associated image element of the image matrix lies between a lower value and an upper limit value.
