디지털 적외선 사진의 색 표현법에 대한 연구

Abstract

For digital infrared ray, CCD have spectral properties that react to the wave range of 380∼1100nm and also IR cut-off filter that only react to visible rays are used in producing photos. Therefore, by removing the cut-off filter, it can react to both visible rays and infrared rays. By applying infrared ray filter here, we can produce infrared photos. This study aimed to produce a digital color infrared photograph by using a color filter that has specific wave (smaller than infrared ray wave) to add the color of visible rays to the subject that infrared rays are reflected. This study, using different filters, enables color changes by adding color to infrared photos in black and white. That is, by understanding the spectral properties of CCD that are the emersions used in digital photography and through the comparison of different colors created by different filters, we will be able to produce color infrared photos.
