Digital camera and finder device thereof

摘要

Provided are a polarization beam splitter 69 disposed between a subject side finder window 16 and a photographer side observation window 17 and disposed to be obliquely inclined at 45 degrees with respect to an optical axis L of an incident light from the subject side finder window 16, a polarizing filter installed at the incident light entering side of the polarization beam splitter 69 and configured to reflect or cut the s-polarized wave of the incident light; and a display device 61 configured to project a display information of the s-polarized wave on the polarization beam splitter 69 and project the display information reflected from the polarization beam splitter 69 in a direction of the photographer side observation window 17.

主权项

1. A finder device, comprising:
a polarization beam splitter disposed between a subject side finder window and a photographer side finder observation window, and disposed to be obliquely inclined at 45 degrees with respect to an optical axis of an incident light entering from the subject side finder window; a polarizing filter installed at an incident light entering side of the polarization beam splitter and configured to reflect or cut s-polarized wave of the incident light; and a display device configured to project a display information of the s-polarized wave on the polarization beam splitter and project the display information reflected from the polarization beam splitter in a direction of the photographer side finder observation window.
