发明名称 Image sensing apparatus which intentionally retains longitudinal chromatic aberration
摘要 An image sensing apparatus has an optical lens system and a color image sensing device. The optical lens system forms an image on the color image sensing device by means of light from an illuminated subject. The color image sensing device is a charge coupled device which has a plurality of pixels. The apparatus fulfills the conditions:where p is a predetermined pitch of a photoelectrically converted pixel of said color image sensing device, LBe is a paraxial back Ad focal length of an e-line (546.07 nm in wavelength), LBg is a paraxial back focal length of a g-line (435.84 nm in wavelength), LBc is a paraxial back focal length of a C-line (656.28 nm in wavelength), and FNo. is an F-number of said optical lens.
