Abstract: A dew removing device for a refrigerator camera and a method of controlling the same are disclosed. The method comprises a step S1 of, when a refrigerator door is opened, turning on a power of a camera unit and a power of a resistor; a step S2 of, when a set time has passed after the step S1, turning off the power of the camera unit and the power of the resistor; and a step S3 of, when the refrigerator door is closed before the set time has passed after the step S1, turning on a power of a lighting unit after a first dew removal time has passed, and capturing an inside of a storage compartment by the camera unit. The method can provide a user with a clear image of a food storage state by removing a dew generated on the lens surface of the camera.

Abstract: Disclosed herein is an inspection method for a display panel according to the present embodiments comprising driving the display panel so as to display a first color having a first reference brightness level; photographing the display panel to obtain a first image including at least one particle region; deriving a first particle brightness level of the particle region contrasted to the first reference brightness level from the first image; driving the display panel so as to display a second color having a second reference brightness level higher than the first reference brightness level; photographing the display panel to obtain a second image containing the particle region; deriving a second particle brightness level of the particle region contrasted to the second reference brightness level; and if the second particle brightness level is higher than the first particle brightness level, determining the particle region to be an internal particle.
