Solid-state image pickup apparatus with positioning mark indicating central part of light-receiving section of solid-state image sensing device and electronic device comprising the same
A solid-state image pickup apparatus 100 of the present invention includes a transparent cover section 24 which is provided so as to be spaced from a lens section, the transparent cover section 24 being provided (i) so as to face a light-receiving section of a solid-state image sensing device 22 and (ii) so as to have a gap between the solid-state image sensing device 22 and the transparent cover section 24 . Furthermore, the transparent cover section 24 is provided with a positioning mark which serves as a reference for positioning the lens section in consideration of the solid-state image sensing device 22 . Consequently, it is possible to provide a shock-resistant solid-state image pickup apparatus in which a lens section and an image pickup section are positionally aligned with high accuracy.
1. A solid-state image pickup apparatus comprising:
a lens section which forms a subject image; and
an image pickup section which converts the subject image formed by the lens section, into an electric signal, the image pickup section including:
a wiring substrate;
a solid-state image sensing device which is mounted on the wiring substrate; and
a transparent cover section which is provided (i) so as to face a light-receiving section of the solid-state image sensing device and (ii) so as to have a gap between the solid-state image sensing device and the transparent cover section, the solid-state image sensing device and the transparent cover section each being provided so as to be spaced from the lens section, and the transparent cover section being provided with a positioning mark which serves as a reference for positioning the lens section in consideration of the image pickup section,
the positioning mark indicates a central part of the light-receiving section of the solid-state image sensing device; and
the positioning mark is a light-emitting film which is transparent under external light and which emits light under black light irradiation.
2. The solid-state image pickup apparatus as set forth in claim 1 , wherein:
a surface of the transparent cover section which surface faces the solid-state image sensing device is larger in area than the light-receiving section of the solid-state image sensing device.
3. The solid-state image pickup apparatus as set forth in claim 1 , wherein:
an adhering section which adheres the transparent cover section to the solid-state image sensing device is provided around the light-receiving section of the solid-state image sensing device.
4. The solid-state image pickup apparatus as set forth in claim 1 , wherein the positioning mark is a reflecting film which is provided on the transparent cover section.
5. The solid-state image pickup apparatus as set forth in claim 1 , wherein the image pickup section is sealed with a resin in such a manner that the resin does not block off an optical path.
6. An electronic device comprising a solid-state image pickup apparatus, the solid-state image pickup apparatus including:
a lens section which forms a subject image; and
an image pickup section which converts the subject image formed by the lens section, into an electric signal, the image pickup section including:
a wiring substrate;
a solid-state image sensing device which is mounted on the wiring substrate; and
a transparent cover section which is provided (i) so as to face a light-receiving section of the solid-state image sensing device and (ii) so as to have a gap between the solid-state image sensing device and the transparent cover section, the solid-state image sensing device and the transparent cover section, each being provided so as to be spaced from the lens section, and the transparent cover section being provided with a positioning mark which serves as a reference for positioning the lens section in consideration of the image pickup section,
the positioning mark indicates a central part of the light-receiving section of the solid-state image sensing device; and
the positioning mark is a light-emitting film which is transparent under external light and which emits light under black light irradiation.
7. The electronic device as set forth in claim 6 , wherein a surface of the transparent cover section which surface faces the solid-state image sensing device is larger in area than the light-receiving section of the solid-state image sensing device.
8. The electronic device as set forth in claim 6 , further comprising an adhering section around the light-receiving section of the solid-state image sensing device for securing the transparent cover section to the solid-state image sensing device.
9. The electronic device as set forth in claim 6 , wherein the transparent cover section is made from transparent glass or resin, and includes an optical filter coating on the transparent glass or resin.
10. A solid-state image pickup apparatus as recited in claim 3 , wherein the adhering section forms a ventilation hole in fluid communication with the gap.
