Abstract
A method of recording a medicament dose using a data collection device comprises capturing an image of a medicament dose indicator of a medicament delivery device, adjusting a scale of said image, adjusting said image for skew of one or more characters displayed by the medicament dose indicator, determining the position of at least one of said one or more characters in the image, identifying the at least one character using optical character recognition and determining a medicament dose indicator by the medicament dose indicator based on a result of the optical character recognition. The method may be performed using a handheld electronic device comprising a camera, such as a cellphone, a tablet computer or other device. A computer program for controlling a data collection device to perform the method may be provided in the form of a software application or “app”.
