Abstract
This invention relates to systems and methods for imaging sample materials within a microfluidic device during an assay reaction process. In accordance with certain aspects of the invention, images are formed with a pixel array and a region of interest ('ROI') is defined within the pixel array. Image values, such as fluorescent intensity, can be computed as averages of individual pixel values within the ROI. Where the ROI is subject to non-uniform conditions, such as non-uniform heating, the ROI can be divided into sub-ROIs which are sufficiently small that the condition is uniform within the sub-ROI.
