Abstract:
1. A control apparatus which is communicably connected to each of an image pickup device and a light source device and collectively controls an operation of the image pickup device and the light source device, the control apparatus comprising a control unit configured to control a cycle from a first irradiation start timing to a second irradiation start timing to be shorter than a cycle of each of first and second picture periods by a readout period of one horizontal line, the first irradiation start timing being a timing at which the light source device starts radiating pulsed illumination light in the first picture period in which the image pickup device performs reading, and the second irradiation start timing being a timing at which the light source device starts radiating the illumination light in the second picture period succeeding the first picture period and having the same cycle as the first picture period, wherein the image pickup device is configured to read out an imaging signal generated by a plurality of pixels for each horizontal line, the plurality of pixels being arranged in two dimensions to generate the imaging signal by performing photoelectric conversion on an optical image of a subject, and the light source device includes a light source configured to generate the pulsed illumination light with which the subject is irradiated at a timing overlapping with a readout period that is a period in which the imaging signal is read out for each horizontal line from the image pickup device.
