Abstract:
1. A microscopic imaging apparatus that can make time lapse capturing for repeatedly obtaining a digital image at desired capturing intervals, the apparatus comprising: a system controlling unit for obtaining (i) a VD time setting value which is a value obtained by calculating a number of cycles of a horizontal synchronization signal within a capturing interval, and (ii) a number of electric charge subtracting pulses by calculating a number of cycles of the horizontal synchronization signal in a duration from a shooting start until an exposure start timing in order to set an exposure time within the capturing interval; a synchronization signal generating unit for generating a vertical synchronization signal based on the VD time setting value output from the system controlling unit and the horizontal synchronization signal; and a timing generating unit for extracting an electric charge of an imaging device by supplying the horizontal synchronization signal by the number of electric charge subtracting pulses to the imaging device as the electric charge subtracting pulses, and for generating a read pulse synchronous with the vertical synchronization signal in order to stop accumulation of the electric charge of the imaging device after exposure is started.
