撮像装置及び撮像方法
Document Type and Number:
Japanese Patent JP6437766
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce moire and to improve a modulation degree.SOLUTION: In a four-plate imaging apparatus, G1R and BG2 pixels are disposed (in a Bayer array). A low frequency component of R output video is defined as an R signal, a low frequency component of B output video is defined as a B signal, and a low frequency component of G output video is defined as an average value of a G1 signal and a G2 signal. During low-sensitivity imaging, an average of an alternating signal of the G1 signal and an R signal and an alternating signal of the G2 signal and the B signal is defined as a high frequency component of the R output video, a high frequency component of the G output video and a high frequency component of the B output video. During high-sensitivity or lawn imaging, an alternating signal of G1 signal and G2 signal is defined as the high frequency component of R output video, the high frequency component of the G output video and the high frequency component of the B output video.SELECTED DRAWING: Figure 2A
