In the digital intervalometer disclosed herein, a vernier measurement providing a resolution finer than one clock period is obtained by charging a single capacitor both during the interval between a start signal and a subsequent clock pulse and also during the interval between a clock pulse subsequent to a stop signal and a delayed stop signal. The analog voltage to which the capacitor is charged is converted to a digital value, which digital value is then combined with a clock count accumulated between the stop and start signals to provide a combined digital measurement having a resolution substantially finer than one clock period.
