The present invention relates to a surface-treated steel plate and to a production method for same, and more specifically relates to a surface-treated steel plate having outstanding corrosion resistance and thermal conductivity. In order to achieve this aim, in the present invention a macromolecular resin composition comprising graphene, which has highly outstanding physical properties including electrical conductivity, is coated onto the surface of a steel foundation plate, thereby making it possible to provide a surface-treated steel plate able to supremely well ensure not only corrosion resistance but also the intrinsic characteristics of graphene due to the macromolecular resin composition.

Surface-treated steel plate and production method for same

Provided are a resin composition for surface treatment and a surface-treated steel sheet coated therewith. The resin composition for surface treatment includes a dispersing element having excellent thermal conductivity and heat dissipation, thereby maintaining physical properties of the conventional anti-fingerprint steel sheet, for example, high whiteness, fingerprint resistance, workability, electric conductivity and alkali resistance, and providing heat dissipation. In addition, the surface-treated steel sheet coated with the resin composition for surface treatment of the present invention has physical properties such as high heat dissipation, electric conductivity and whiteness, and thus may be replaced with a bottom chassis of a backlight unit, particularly, an edge-type backlight unit.

An illumination normalizing apparatus and a method are disclosed. The illumination normalizing apparatus measures a discontinuity of each pixel of an input image, the discontinuity including a spatial gradient and a local inhomogeneity, produces a weight of each pixel from the discontinuity by using a transfer function, produces an estimated illumination by repeating a convolution operation on each weight, and subtracts the estimated illumination from the input image.
