ROBOT CLEANER
First Claim
1. A robot cleaner comprising:
- a main body configured to clean a floor while autonomously traveling within a cleaning area;
a light irradiation module configured to irradiate light towards a region in front of the main body;
an image sensor including a plurality of horizontal lines sequentially exposed to form an image of the region in front of the main body;
an image processor configured to construct frames by synchronizing signals output from the horizontal lines, such that after construction of any one frame, the image processor does not construct one or more frames by ignoring signals output from the horizontal lines, and then constructs a next frame; and
a controller configured to control the light irradiation module to irradiate light while the horizontal lines are exposed to construct the one frame, such that the light irradiation module stops irradiation of light between before exposure of all the horizontal lines to construct the one frame is completed and one point of time while the image processor ignores signals output from the horizontal lines.

Abstract
A robot cleaner may include a main body, a light irradiation unit irradiating light towards a region in front of the main body, an image sensor including a plurality of horizontal lines sequentially exposed to form an image, an image processing unit constructing frames by synchronizing signals output from the horizontal lines, such that, after construction of any one frame, the image processing unit does not construct one or more frames by ignoring signals output from the horizontal lines, and then constructs a next frame, and a controller controlling the light irradiation unit to irradiate light while the horizontal lines are exposed to construct the one frame, such that the light irradiation unit stops irradiation of light between before exposure of all the horizontal lines to construct the frame is completed and one point of time while the image processing unit ignores signals output from the horizontal lines.

13. A vacuum cleaner comprising:
-
a main body including at least one motor to suction air through a suction hole provided with a roller brush and to allow the main body to move autonomously for cleaning a floor surface within an area to be cleaned; a laser to irradiate light towards a region in front of the main body; a camera configured to capture at least one image in front of the main body; an image processor to process the at least one image captured by the camera; a synchronization generator to generate a plurality of synchronization signals; and a controller to control the motor, the laser, the camera, the image processor, and the synchronization generator, wherein the synchronization generator generates first, second and third synchronization signals during a prescribed time period, the camera captures images during the prescribed time period, the laser is turned on when the first and third synchronization signals are generated and is turned off when the second synchronization signal is generated, and the image processor processes first and second images captured by the camera when the laser is turned on based on the first and third synchronization signals and discards a third image captured by the camera when the laser is turned off based on the second synchronization signal. - View Dependent Claims (14, 15, 16, 17)
