Image-capturing apparatus
An image-capturing apparatus according to an embodiment of the present technology includes a camera, a lighting section, a sensor section, and an image-shooting controller. The lighting section includes a light entrance that at least a portion of external light enters, and an object for calibration that is irradiated with the external light entering the light entrance. The sensor section detects a state of the object for calibration irradiated with the external light. The image-shooting controller controls the camera according to a result of the detection performed by the sensor section.
