Referring to fig. 3 to 4, a photographing device 100 according to a first embodiment of the invention includes a sensing module 5, a holder 6, a lens module 7, and a filter module 8.
The sensing module 5 includes a sensing chip 51, and the sensing chip 51 includes a receiving surface 511 for receiving light, the receiving surface 511 has two end edges 511a located at opposite sides, and two side edges 511b connected to the end edges 511a and located at opposite sides. The fixing member 6 is disposed on the sensing module 5 and has a fixing portion 61. The lens module 7 is fixed on the fixing portion 61 of the holder 6, and the lens module 7 includes a lens light-emitting portion 71 at the bottom thereof for transmitting light to the receiving surface 511 of the sensor chip 51.
The optical filtering module 8 is disposed between the receiving surface 511 of the sensing chip 51 and the lens light-emitting portion 71 of the lens module 7, and the optical filtering module 8 includes an optical filter 81 for filtering light and a light-shielding layer 82 which is disposed on the optical filter 81 and is made of opaque material. In the first embodiment, the light shielding layer 82 is disposed on the top surface of the optical filter 81, but in other embodiments, the light shielding layer 82 may be disposed on the bottom surface of the optical filter 81, and is not limited thereto. The light shielding layer 82 is formed with a light transmitting opening 821 for light to pass through to reach the receiving surface 511 of the sensor chip 51, and the light transmitting opening 821 has a light transmitting portion 821a located at the center, two end edge positioning portions 821b connected to the periphery of the light transmitting portion 821a and located above the end edges 511a, and two side edge positioning portions 821c connected to the periphery of the light transmitting portion 821a and located above the side edges 511 b. The positions of the end edge positioning portions 821b and the side edge positioning portions 821c projected on the receiving surface 511 are respectively located on the corresponding end edge 511a and side edge 511b, and are spaced apart from the connecting portion of the adjacent corresponding end edge 511a and side edge 511b, that is, the end edge positioning portions 821b and the side edge positioning portions 821c are not connected to each other.
It should be noted that the end edge positioning portions 821b and the side edge positioning portions 821c are designed to allow the filter module 8 to be easily positioned relative to the end edge 511a and the side edge 511b of the receiving surface 511 of the sensor chip 51, and the positions of the end edge positioning portions 821b and the side edge positioning portions 821c projected on the receiving surface 511 are spaced from the connecting portions of the adjacent corresponding end edge 511a and side edge 511b, so that light rays not passed through the lens module 7 (for example, light rays entering from the gap between the retainer 6 and the lens module 7) are not easily incident on the receiving surface 511 through the end edge positioning portions 821b and the side edge positioning portions 821c of the light shielding layer 82, thereby avoiding defects of the photographed image.
In the first embodiment, the end edge positioning part 821b and the side edge positioning part 821c are substantially rectangular in shape having two long sides and two short sides, and the connection between the end edge positioning part 821b and the side edge positioning part 821c and the translucent part 821a is a long side.
In the first embodiment, the positions of the end edge positioning portions 821b and the side edge positioning portions 821c projected on the receiving surface 511 are spaced from the midpoints of the corresponding end edges 511a and side edges 511b by a distance, so that the light entering the receiving surface 511 through the end edge positioning portions 821b and the side edge positioning portions 821c is farther from the center of the receiving surface 511, and the light passing through the end edge positioning portions 821b and the side edge positioning portions 821c does not affect the overall photographing quality.
In addition, the end edge positioning part 821b and the side edge positioning part 821c are adjacent to each other two by two in the first embodiment, but in other embodiments, the end edge positioning part 821b and the side edge positioning part 821c may be dispersed at four corners adjacent to the light transmission part 821a, respectively, and the present invention is not limited thereto.
Referring to fig. 5, a second embodiment of the image capturing device 100 according to the present invention is substantially the same as the first embodiment except that the end edge positioning portion 821b and the side edge positioning portion 821c are substantially triangular with a bottom side and two side edges, and the bottom sides of the end edge positioning portion 821b and the side edge positioning portion 821c are spaced apart from the corresponding edges of the translucent portion 821a in parallel.
In the first and second embodiments, the end edge positioning portion 821b and the side edge positioning portion 821c are substantially rectangular and triangular, but the end edge positioning portion and the side edge positioning portion may have other shapes, and are not limited to the two embodiments.
As described above, in the photographing device 100 and the filter module 8 thereof according to the present invention, the edge positioning portions 821b and the side edge positioning portions 821c allow the filter module 8 to be easily positioned on the sensor chip 51, and since the positions of the receiving surface 51 where the edge positioning portions 821b and the side edge positioning portions 821c are projected are spaced apart from the connecting portions between the adjacent corresponding edge 511a and side edge 511b, the light beams that do not pass through the lens module 7 are not easily incident on the receiving surface 511 of the sensor chip 51 through the edge positioning portions 821b and the side edge positioning portions 821 c. Further, since the positions of the end edge positioning portions 821b and the side edge positioning portions 821c projected on the receiving surface 511 are spaced from the midpoints of the corresponding end edges 511a and side edges 511b by a distance, the light passing through the end edge positioning portions 821b and the side edge positioning portions 821c does not affect the overall image quality, and thus the object of the present invention can be achieved.
It should be understood that the above description is only exemplary of the present invention, and that the scope of the present invention should not be limited thereby, and that the invention is intended to cover all modifications and equivalents included within the scope of the appended claims and the description.
