SOLID-STATE IMAGE PICKUP DEVICE

摘要: PROBLEM TO BE SOLVED: To hardly cause a false signal even by mounting deviation of diffraction grating type optical low pass filter setting the period solid-state image pickup element in pixel arrangement direction specified times solid element. SOLUTION: This 12 is CCD(charge coupled device) consisting many pixels 12a arranged fixed ΛCCD. The low-pass 13 mounted so that pattern becomes parallel to 12. At this time, provided with since wave shape pattern, and ΛMLA close 3.0 ΛCCD 12, is, ΛMLA≈3.0ΛCCD. Thus, very small value extent, visible shadow never caused on 13.
