Abstract: A method for preparing a highly elastic biodegradable three-dimensional structure includes (a) mixing poly(lactide-co-?-caprolactone) (PLCL) with at least one biocompatible heat stabilizer that is biocompatible with the PLCL, that is a heat stabilizer for the PLCL, and that is selected from the group consisting of ?-tocopherol, barium-zinc, calcium-zinc, vitamin B, and combinations thereof to provide a solvent-free mixture; and (b) carrying out three-dimensional printing with the solvent-free mixture by heating the mixture at 150-250° C. for 5-20 minutes to provide a heated mixture; and ejecting the heated mixture through a nozzle. The three-dimensional structure maintains mechanical properties even after three-dimensional printing, by adding a biocompatible heat stabilizer to poly(L-lactide-co-?-caprolactone). The three-dimensional structure is useful as a scaffold for tissue engineering.

Abstract: An image signal processing device is disclosed, including a sensitivity improvement unit, a Bayer RGB conversion unit, and a color correction unit. The sensitivity improvement unit interpolates input white, red, green, and blue (WRGB) data, mixes a luminance signal of first color space data for the interpolated WRGB data with a first type pixel signal of the interpolated WRGB data to convert the first color space data into second color space data, and converts the second color space data into converted RGB data. The Bayer RGB conversion unit converts color spaces of a second type pixel signal, a third type pixel signal, and a fourth type pixel signal of the interpolated WRGB data to generate the first color space data, and separates the luminance signal and color difference signals from the first color space data. The color correction unit corrects the converted RGB data into output RGB data.

Abstract: An image reproducing method is described. A three-dimensional (3D) image file including a left image and a right image is reproduced. A first channel image is generated from the left image of the 3D image. A second channel image is generated from the right image of the 3D image. The first channel image is combined with the second channel image to generate an output image. The output image is displayed.
