Provided is a control apparatus including a ratio calculation unit that calculates a first ratio of a bit assignment relating to transmission of a biological image on the basis of image capture conditions and a bit assignment determination unit that determines the bit assignment on the basis of the first ratio. In addition, provided is a control system including an image capture apparatus that captures an image of an object, the control apparatus including the ratio calculation unit that calculates the first ratio on the basis of the image capture conditions relating to the object, the bit assignment determination unit that determines the bit assignment, an image processing unit that performs image processing based on the captured image and the bit assignment and generates the biological image, and an output apparatus that outputs the biological image based on the bit assignment.
