IPC: H04N5/372
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To enable imaging rich in color reproducibility even in the case of photographing using single plate type and double plate type image pickup devices by converting an incident optical image to color separated images deviated just for fixed distances different for each color in the arranging direction of pixels of solid-state imaging device on the image pickup plane of this device. SOLUTION: A transparent flat plate 11 having a refraction factor (n) is placed obliquely to an optical axis, and this transparent flat plate 11 is installed while adjusting its incident angle θ and its thickness (t) so that the interval of refracted light beams in three colors R, G and B can become a pixel pitch. For example, when the incident angle θ is 15 deg., the difference of every color deviation quantity, namely, the distance between R and G parts and the distance between the G and B parts are calculated to be 0.95×10<-3> ×(t). When the pixel pitch is 6.8μm, in the case of single plate system, the thickness (t) is set at 7.16mm so that the distance of three primary colors in separated image can be made equal with the pixel pitch.  Besides, since it is enough only to divide two colors R and B into adjacent pixels in the case of multi-plate system, it is enough only to set the thickness (t) to 3.58mm. Thus, color separation control is enabled corresponding to the pixel pitch of imaging device.
