Abstract: A method for forming a thin film pattern is provided to form the fine pattern formation by forming the interference pattern between the optical guided mode and the interference pattern between surface plasmon waves. The surface plasmon wave is excited in the boundary of the photo reactive material of the metallic thin film and the metallic thin film(S101). The interference pattern by the surface plasmon wave is formed(S102). The photo reactive material is exposed by the interference pattern(S105). The light guided mode is formed by the incident light having a specific incident angle to a prism. The photo reactive material is exposed by the interference pattern.

Abstract: A video frame re-compressing method in which a down-sampling type and a maximum-minimum quantization type are combined and an apparatus therefor are provided to combine the down-sampling type and the maximum-minimum quantization type which are relatively simple without using a frequency conversion type in which a hardware size is greatly occupied and a processing time is required for a long time. A re-compressor includes a down-sampling unit(10), an analyzing unit(20), a quantization unit(30), and an integrating unit(40). The down-sampling unit(10) compresses a unit block in horizontal and vertical two directions. The analyzing unit(20) analyzes a result outputted from the down-sampling unit(10), and selects pixels down-sampled in the direction in which difference between the maximum value and the minimum value is greatly generated between the two directions. The quantization unit(30) quantizes and re-compresses the respective pixels down-sampled in the direction selected by the analyzing unit(20). The integrating unit(40) integrates the re-compression data quantized in the quantization unit(30) and a header for inverse compression, and transmits the integrated data to a memory.
