Cleaner and control method thereof

A cleaner performing autonomous traveling, the cleaner comprising:

• a main body;
• a driving unit moving the main body;
• a camera capturing an image around the main body;
• and
• a controller controlling the driving unit to move the main body in at least one of a plurality of traveling modes using the image captured through the camera,
• wherein the camera is a single camera,
• wherein each of the plurality of traveling modes is preset with a different illumination value,
• wherein the controller controls the camera to capture the image with a preset illumination according to performing one of the plurality of traveling mode,
• wherein the controller controls the camera to capture an image with a first illumination when the main body travels in a first traveling mode of the plurality of traveling modes, and to capture an image with a second illumination different from the first illumination when the main body travels in a second traveling mode different from the first traveling mode of the plurality of traveling modes,
• wherein the first illumination is set to be lower than the second illumination,
• wherein when the first traveling mode and the second traveling mode are selected, the controller detects a number of images used per unit time in the first traveling mode and a number of images used in the second traveling mode,
• wherein the number of images used per unit time in the first traveling mode is a first number,
• wherein the number of images used per unit time in the first traveling mode is a second number, and
• wherein when the first and second traveling modes are selected, while the camera is obtaining a preset number of images per second, the controller controls the camera such that at least the first number of images captured with the first illumination is included in the obtained images and at least the second number of images captured with the second illumination is included in the obtained images.
