With the introduction of HD video recording function, the DSLR camera equipped with large CMOS has recently been attracting high interests from many fields, including picture, movie and broadcasting. Based on the recognition that the utilizability of the video recorded by DSLR camera depends on the image expression ability of recorded HD video, the present research conducted an analysis to compare the video recorded by DSLR camera with that recorded by existing HD video camera and also with the still image obtained by DSLR camera. For a detailed analysis, both objective research and subjective research were carried out. The objective research involved videos and still images of a standard chart recorded by DSLR camera and HD video camera, to comparatively analyze the resolution, dynamic range, noise and color reproduction between the two kinds of camera. Whereas the subjective research involved video recording of person, scenery and night view which have been appearing frequently in image, to comparatively analyze the characteristics between the recorded videos. According to the results of measurement, the video recorded by DSLR camera proved better performance of DSLR camera compared to existing HD video camera in resolution, dynamic range and noise, thus proving the utilizability of DSLR camera. In color expression, however, HD video camera showed better performance. There was a limitation to utilizing the video recorded by DSLR camera for photograph purposes, yet the research proved its utilizability for small size printing and internet.
