Abstract

A control system controls an imaging device to generate an omnidirectional image based on a first image obtained using a first fisheye lens and a second image obtained using a second fisheye lens. The control system includes an evaluation value calculating unit configured to: calculate brightness values of the first and second images based on pixel values of pixels constituting the first and second images, and calculate, based on the brightness values, first and second exposure evaluation values for evaluating exposure of first and second imaging elements corresponding to the first and second fisheye lenses. The evaluation value calculating unit configured to do not use pixel values of pixels constituting an overlapping area in which there is overlapping of shooting ranges of the first and second images, during calculation of the brightness values of the first and second images.

A control system to control an imaging device to generate an omnidirectional image based on a first image obtained using a first fisheye lens and a second image obtained using a second fisheye lens, the control system comprising:

an evaluation value calculating circuitry configured to:
calculate a brightness value of the first image based on pixel values of pixels constituting the first image,
calculate, based on the brightness value, a first exposure evaluation value for evaluating exposure of a first imaging element corresponding to the first fisheye lens,
calculate a brightness value of the second image based on pixel values of pixels constituting the second image, and
calculate, based on the brightness value, a second exposure evaluation value for evaluating exposure of a second imaging element corresponding to the second fisheye lens, wherein
the evaluation value calculating circuitry is configured to not use pixel values of pixels constituting an overlapping area in which there is overlapping of a shooting range of the first image and a shooting range of the second image, during calculation of the brightness value of the first image and calculation of the brightness value of the second image.
