Abstract

A method for evaluating the suitability of a mobile device having a camera for performing an analytical measurement is disclosed. The method includes providing the mobile device and providing a reference object having a predefined spatial extension in a spatial dimension. An image is taken of at least part of the reference object using the camera and is used to derive spatial resolution information that includes one or more numerical values that quantify the capability of the camera to resolve two or more objects in the image. A threshold value based on a minimum number of pixels in the spatial dimension within a region of interest in the image is provided and the spatial resolution information is compared with the threshold value. It is determined from the comparison whether the mobile device is suitable for performing the analytical measurement.
