A method for detecting at least one analyte in at least one sample of a body fluid is disclosed. Therein, at least one test element (124) is used, the at least one test element (124) having at least one test field (162) with at least one test chemistry (154) is used, wherein the test chemistry (154) is adapted to perform at least one optically detectable detection reaction in the presence of the analyte. The method comprises acquiring an image sequence of images of the test field (162) by using at least one image detector (178). Each image comprises a plurality of pixels. The method further comprises detecting at least one characteristic feature of the test field (162) in the images of the image sequence. The method further comprises correcting a relative position change between the image detector (178) and the test field (162) in the image sequence by using the characteristic feature, thereby obtaining a sequence of corrected images.
A method for detecting at least one analyte in at least one sample of a body fluid, wherein at least one test element with at least one test field is used, the at least one test field having at least one test chemistry, wherein the test chemistry is adapted to perform at least one optically detectable detection reaction in the presence of the analyte, wherein the method comprises acquiring an image sequence of images of the test field by using at least one image detector, wherein each image comprises a plurality of pixels, wherein the method further comprises detecting using a control unit at least one characteristic feature of the test field in the images of the image sequence, wherein the method further comprises correcting using the control unit a relative position change between the image detector and the test field in the image sequence by using the characteristic feature, thereby obtaining at least one corrected image.
A device for detecting at least one analyte in at least one sample of a body fluid, wherein the device comprises at least one test element receptacle for receiving at least one test element having at least one test field with at least one test chemistry, wherein the device further comprises at least one image detector for acquiring an image sequence of images of the test field, wherein the device further comprises at least one control unit, wherein the control unit is adapted to:
