and a control device that controls testing of the test body based on images acquired by the camera, wherein the control device comprises: a recognition portion that recognizes a state of the test body based on the images; and a test control portion that controls a predetermined test when the state of the test body as recognized by the recognition portion attains a predetermined state. ### Claim 2 (depends on 1) The vehicle testing system according to claim 1, further comprising an automatic driving device that drives the test body automatically on the test bench, wherein the test control portion controls the automatic driving device in accordance with recognition results from the recognition portion. ### Claim 3 (depends on 1) The vehicle testing system according to claim 1, further comprising an analysis device that analyzes exhaust gas emitted from the test body, wherein the test control portion controls the analysis device in accordance with recognition results from the recognition portion. ### Claim 4 (depends on 1) The vehicle testing system according to claim 1, wherein the recognition portion detects changes in the images acquired by the camera, and determines the state of the test body based on the detected changes in the images. ### Claim 5 (depends on 1) The vehicle testing system according to claim 1, wherein the control device further comprises a data storage portion in which image data associated with the states of the test body is stored in advance, and the camera acquires images of the state display portion at timings when the state display portion is fully illuminated, and the recognition portion recognizes positions of the image data in the state display portion by searching for the image data stored in the data storage portion from the images of the state display portion when fully illuminated acquired by the camera. ### Claim 6 (depends on 5) The vehicle testing system according to claim 5, wherein the recognition portion recognizes states of the test body based on changes in a portion of the images, out of the images acquired by the camera, for which positions of the image data have been established. ### Claim 7 (depends on 1) The vehicle testing system according to claim 1, wherein the recognition portion recognizes a remaining battery charge of the test body as the state of the test body, and, in a case in which the remaining battery charge has reached a predetermined value, the test control portion controls predetermined tests. ### Claim 8 (depends on 1) The vehicle testing system according to claim 1, wherein the recognition portion recognizes an ON/OFF state of a main power supply of the test body as the state of the test body, and, in a case in which the main power supply of the test body is turned ON, the test control portion controls vehicle testing of the test body. ### Claim 9 A vehicle testing method in which a test body in a form of a vehicle or a part of a vehicle is tested on a test bench, in which images of a portion of the test body are acquired and vehicle testing is controlled based on the acquired images, the vehicle testing method comprising: recognizing a state of the test body based on the images, wherein the images are of a state display portion of the test body that displays states of the test body to a driver of the test body; and controlling a portion of a predetermined test when the state of the test body as recognized by a recognition portion attains a predetermined state. ### Claim 10 A vehicle testing system that tests a test body in a form of a vehicle or a part of a vehicle, comprising: a test bench for simulated driving of the test body; a camera that acquires images of a portion of the test body on the test bench; and a control device that controls testing of the test body based on images acquired by the camera, wherein the control device comprises: a recognition portion that recognizes a state of the test body based on the images; and a test control portion that controls a predetermined test when the state of the test body as recognized by the recognition portion attains a predetermined state.
