Abstract: Disclosed are calibration techniques that can be implemented by a device that conducts biological tests. In certain embodiments, the device for testing a biological specimen includes a receiving mechanism to receive a carrier, a camera module arranged to capture imagery of the carrier, and a processor. Some examples of the processor can detect a calibration mode trigger. In calibration mode, the processor can divide the captured imagery into segments and selectively perform one or more calibration procedures for each segment. Then, the processor records a calibration result for each segment.
