Abstract
Methods and digital imaging devices disclosed herein are adapted to capture images of a specimen in a chemical reaction using a series of short exposures of light emissions from the specimen over a period of time. The series of short exposures is captured using an array of pixels of an image sensor in the digital imaging device that are configured for performing continuous non-destructive read operations to read out a set of non-destructive read images of the specimen from the pixel array. In one embodiment, images are captured by delaying the read out until at or near the end of the chemical reaction to reduce read noise in the images. The signals read out from the image sensor can be continuously monitored and the capturing of images can be discontinued either automatically or based on a command from a user. The captured images can then be displayed in a graphical display.
