Provided is a method of restoring and / or reconstructing a super-resolution image from low-resolution images compressed in a digital video recorder (DVR) environment. The present invention can remove a blur of a video sequence, caused by optical limitations due to a miniaturized camera of a digital video recorder monitoring system, a limitation of spatial resolution due to an insufficient number of pixels of a CCD / CMOS image sensor, and noises generated during image compression, transmission and storing processes, to restore high-frequency components of low-resolution images (for example, the face and appearance of a suspect or numbers of a number plate) to reconstruct a super-resolution image. Consequently, an interest part of a low-resolution image stored in the digital video recorder can be magnified to a high-resolution image later, and the effect of an expensive high-performance camera can be obtained from an inexpensive low-performance camera.

A method is described for reducing the space width of holes in a first resist pattern and simultaneously removing unwanted holes to change the pattern density in the resulting second pattern. This technique provides holes with a uniform space width as small as 100 nm or less that is independent of pattern density in the second pattern. A positive resist is patterned to form holes with a first pattern density and first space width. A water soluble negative resist is coated over the first resist and selectively exposed to form a second patterned layer consisting of water insoluble plugs in unwanted holes in the first pattern and a thin water insoluble layer on the first resist pattern in unexposed portions. The plugs may form dense and isolated hole arrays while the thin insoluble layer reduces space width to the same extent in remaining holes in the second pattern.
