Patent ID: 8587082

Claim:
An imaging device comprising: an optical sensor including a light receiving unit capable of forming an object image; a seal material for protecting the light receiving unit of the optical sensor; an intermediate layer formed at least between the light receiving unit and an opposite surface of the seal material facing the light receiving unit; a control film arranged between the intermediate layer and the opposite surface of the seal material; and an infrared cut filter shielding light in an infrared range arranged in an optical path to the light receiving unit of the optical sensor, wherein in the control film, a cutoff wavelength is shifted to a shortwave side in accordance with an incident angle of light which is obliquely incident on the film, and cutoff wavelengths and cutoff line widths of the multilayer film and the infrared cut filter satisfy the following condition: λ cf — IRCF+Δλcf — IRCF/ 2 <λcf — ML−Δλcf — ML/ 2 where, λcf_IRCF represents a cutoff wavelength of the infrared cut filter, Δλcf_IRCF represents a cutoff line width of the infrared cut filter, λcf_ML represents a cutoff wavelength of the control film and Δλcf_ML represents a cutoff line width of the control film.
