  • Image pickup apparatus
    Patent number: 8313254
    Abstract: An image pickup apparatus includes a light-beam splitting mirror configured to transmit and reflect incident light that has entered the light-beam splitting mirror through a photographing optical system; an image sensor that receives light transmitted through the light-beam splitting mirror; an autofocus detecting unit that receives light reflected by the light-beam splitting mirror; a signal processing unit configured to process an image pickup signal of the image sensor; and a display unit configured to display an image being photographed, on the basis of an image signal obtained at the signal processing unit. In the image pickup apparatus, the light-beam splitting mirror has spectral characteristics including a reflectivity of 25% or more and 35% or less at a wavelength of 400 to 650 nm and a reflectivity of 60% or more at a wavelength of about 700 nm through optimization.
