Patent number: 11727546Abstract: A method for correcting an image includes: orthographically correcting an image; removing a curtain artifact by applying a first filter to the orthographically corrected image; correcting brightness of the image, from which the curtain artifact is removed, by applying a second filter to the image, from which the curtain artifact is removed. The first filter includes a first function and a second function for a first domain and a second domain, which are orthogonal to each other in a frequency region, and the first filter is differentiable and continuous in the first domain and the second domain.Type: GrantFiled: March 9, 2022Date of Patent: August 15, 2023Assignees: SAMSUNG ELECTRONICS CO., LTD., RESEARCH & BUSINESS FOUNDATION SUNGKYUNKWAN UNIVERSITYInventors: Sihyung Lee, Dongjae Kim, Jae Wook Nam, Wooram Hong

Patent number: 6089146Abstract: A temperature sensing device for a food storage container accurately detects the internal temperature of a storage chamber to achieve an accurate on/off control for heating and cooling cycles by minimizing a temperature fluctuation existing in the storage chamber. The temperature sensing device includes a temperature sensor to sense a temperature of the storage chamber and generate an electrical signal representative of the sensed temperature; a control unit, having a microprocessor, to control the cooling system based on the electrical signal generated by the temperature sensor; and a metallic fixing bracket for fixing the temperature sensor to the inner liner at a position near an inlet portion of an evaporator receiving a cooled refrigerant from a condenser, such that the temperature sensor is in close contact with the outer surface of an inner liner of the storage chamber, to establish a thermally conductive path between the inner liner and the temperature sensor.Type: GrantFiled: November 12, 1999Date of Patent: July 18, 2000Assignee: Mando Climate Control CorporationInventors: Jae-wook Nam, Bo-youn Son
