An endoscope includes: an illuminator configured to guide illumination light from a light source capable of emitting the illumination light intermittently and apply the illumination light to an object; an imaging element including a light receiver where multiple pixels configured to receive light and perform photoelectric conversion to generate electric signals are arranged in a two-dimensional matrix, and a reader configured to sequentially read the electric signals per horizontal line from each of the multiple pixels; a generator configured to, based on a first vertical synchronization signal that is input from an external processor and reference timing of exposure of the imaging element with the illumination light, generate a second vertical synchronization signal for controlling timing at which the reader reads the electric signal; and an imaging controller configured to cause the reader to read the electric signals sequentially according to the second vertical synchronization signal.
