The light sensing unit 150 receives light and generates an electronic signal to a processor (not shown in FIG. 1 ) to generate image information. The structural features of the lens unit 100 and the light sensing unit 150 will be described below.

Referring to FIG. 2 , it shows a cross-sectional view along section line A-A of FIG. 1 . For the convenience of description, the following description only focuses on the lens unit 100a and the lens unit 100b among the plurality of lens units, and the photo-sensing unit 150a and the photo-sensing unit 150b among the plurality of photo-sensing units.

According to some embodiments of the present invention, the lens unit 100a includes a first base lens 112a, a second base lens 122a, a first functional lens 114a, a second functional lens 116a, a third functional lens 124a, a fourth functional lens The lens 126a, and a light blocking element 118a.

The optical blocking element 118a has an opening 1170a. The opening 1170a is aligned with the optical axis O1. The opening 1170a is axisymmetric to the optical axis O1. The optical blocking element 118b has an opening 1170b. The opening 1170b is aligned with and axisymmetric to the optical axis O2. In some embodiments, the light blocking layer 117 is made of non-transparent material. Light can pass through the light blocking layer 117 through the openings 1170a, 1170b, but is absorbed or reflected by the light blocking layer 117 . In some embodiments, the openings 1170a, 1170b are circular, as shown in FIG. 3 .

Referring to FIG. 2 again, in some embodiments, then, a first lens array layer 113 is formed on the light blocking layer 117 by molding, and a second lens array layer 115 is formed on the light blocking layer 117 by molding. The first base 111 is formed on the surface opposite to the surface of the light blocking layer 117 . Thus, a first stack structure 110 is integrally formed by the first base portion 111 , the first lens array layer 113 , the second lens array layer 115 , and the light blocking layer 117 .

The first lens array layer 113 includes a plurality of first functional lenses, such as a first functional lens 114a and a first functional lens 114b. The second lens array layer 113 includes a plurality of second functional lenses, such as a second functional lens 116a and a second functional lens 116b. The first functional lens 114a and the second functional lens 116a are aligned in the opening 1170a. The first functional lens 114b and the second functional lens 116b are aligned in the opening 1170b. That is, the first functional lens 114a, the opening 1170a, and the second functional lens 116a are arranged along the optical axis O1, and the first functional lens 114b, the opening 1170b, and the second functional lens 116b are arranged along the optical axis O2. The optical axis O1 is parallel to the optical axis O2.

Next, a second base portion 121 is provided, and a third lens array layer 123 and a fourth lens array layer 125 are formed on opposite sides of the second base portion 121 by molding. Thus, a second stack structure 120 is composed of the second base portion 121 , the third lens array layer 123 , and the fourth lens array layer 125 integrally.

The third lens array layer 123 includes a plurality of third functional lenses, such as a third functional lens 124a and a third functional lens 124b. The fourth lens array layer 125 includes a plurality of fourth functional lenses, such as a fourth functional lens 126a and a fourth functional lens 126b. The third functional lens 124a is aligned with the fourth functional lens 126a, and the third functional lens 124b is aligned with the fourth functional lens 126b. In some embodiments, the third functional lens 124a and the fourth functional lens 126a are arranged along the optical axis O1, and the third functional lens 124b and the fourth functional lens 126b are arranged along the optical axis O2.

In some embodiments, the fourth lens array layer 125 is combined with the first lens array layer 113 in a suitable way, such as glued, thereby connecting the first stack structure 110 and the second stack structure 120 .

In some embodiments, the first stack 110 and the second stack 120 are cut into multiple units, each of which includes a plurality of lens units 100 . For example, each unit includes sixteen lens units 100 arranged in a 4×4 matrix, as shown in FIG. 1 .

Continue referring to FIG. 2 , according to some embodiments of the present invention, the light sensing unit 150a includes a substrate 151a and an image capture element 153a, and the light sensing unit 150b includes a substrate 151b and an image capture element 153b. The substrate 151a and the substrate 151b are integrally formed. The image capture element 153a is aligned with the optical axis O1 and disposed on the substrate 151a. The image capture element 153b is aligned with the optical axis O2 and disposed on the substrate 151b. The image capture device 153 a and the image capture device 153 b are, for example, complementary metal-oxide-semiconductor (CMOS) image sensors.

As shown in FIG. 4 , in some embodiments, the image capture element 153a is rectangular, and the image capture element 153a has two short sides 1533a and two long sides 1531a. The two short sides 1533a are connected between the two long sides 1531a. In some embodiments, the diameter D of the opening 1170a is smaller than the width W1 of the two long sides 1531a. In some embodiments, the diameter D of the opening 1170a is greater than the width W2 of the two short sides 1533a.

When capturing an image from the outside of the image capturing component 1 , the light passes through the lens unit 100 a and the lens unit 100 b ( FIG. 2 ) and is received by the light sensing unit 150 a and the light sensing unit 150 b. Since part of the light has been blocked by the light blocking layer 117 before being projected on the photo-sensing unit 150a and the photo-sensing unit 150b, the light shape of the light projected to the photo-sensing unit 150a and the photo-sensing unit 150b is formed by the light blocking The opening 1170a and the opening 1170b on the layer 117 are determined.

Therefore, the light passing through the lens unit 100a is prevented from projecting on the image capturing element 153b of the light sensing unit 150b, and the image quality of the image capturing element 153b is further improved. However, since the opening 1170a is circular, part of the light passing through the lens unit 100a may still be projected on another image capturing element 153c that is adjacent to the image capturing element 153a in the extending direction of the two short sides 1533a. This phenomenon will degrade the image quality of the image capture device 153c.

In order to solve the problems of the above-mentioned embodiments, other embodiments are further proposed.

Referring to FIGS. 5 and 6 , FIG. 5 shows a cross-sectional view of the image capture component 2 of some embodiments of the present invention, and FIG. 6 shows a top view of a partial structure of the light blocking layer of some embodiments of the present invention. In FIGS. 5 and 6 , elements similar to those in FIG. 2 will be given the same reference numerals, and their features will not be described again to simplify the description.

The difference between the image capture component 2 and the image capture component 1 shown in FIG. 2 includes that the light blocking layer 117 is replaced by the light blocking layer 217 .

In some embodiments, the light blocking layer 217 is directly formed on the surface of the second substrate 121 by coating. The light blocking layer 217 includes a plurality of light blocking elements, such as a light blocking element 218a and a light blocking element 218b. The light blocking element 218a has an opening 2170a. The opening 2170a is aligned with the optical axis O1. The light blocking element 218b has an opening 2170b. The opening 2170b is aligned with the optical axis O2. In some embodiments, the light blocking layer 217 is made of non-transparent material. Light can pass through the light blocking layer 217 through the openings 2170a and 2170b, but is absorbed or reflected by the light blocking layer 217 .

In some embodiments, the openings partially formed on the light blocking layer 217 are non-axisymmetric to their corresponding optical axes, and the shapes of these openings are related to the shapes of their corresponding image capturing elements. For example, the opening 2170a of the light blocking layer 217 is non-axisymmetric to the optical axis O1. The opening 2170a is rectangular and has two long sides 2171a, 2173a and two short sides 2172a, 2174a.

Referring to FIG. 7 , in some embodiments, the two long sides 2171a, 2173a are parallel to the two long sides 1531a, and the two short sides 2172a, 2174a are parallel to the two short sides 1533a. In some embodiments, the area of the opening is smaller than the area of the corresponding image capture element. For example, the area of the opening 2170a is smaller than the area of the corresponding image capturing element 153a. In some embodiments, the width W3 of the opening 2170a along the two long sides 2171a, 2173a is smaller than the width W1 of the image capturing element 153a along the two long sides 2171a, 2173a. In some embodiments, the width W4 of the opening 2170a along the two short sides 2172a, 2174a is smaller than the width W2 of the image capture element 153a along the two short sides 2172a, 2174a.

Continuing to refer to FIG. 7 , by reducing the aperture ratio of the light blocking layer 217 , the light passing through the light blocking layer 217 through one of the openings will be effectively projected on its corresponding image capture element. For example, the light passing through the opening 2170a of the light blocking layer 217 will be effectively projected on the corresponding image capturing element 153a. Therefore, the quality of the image generated by the image capture component 153b and/or the quality of the image generated by the image capture component 153c is improved.

The shape of the openings of the light blocking layer should not be limited to the above embodiments. Other examples of light blocking layers are provided below.

Referring to FIG. 8 , in some embodiments, at least one opening of the light blocking layer is non-axisymmetric to its corresponding optical axis, and the angle between any two adjacent edges of the opening is not a right angle. For example, the opening 3170 of the light blocking layer 3172 is non-axisymmetric with respect to the optical axis passing through it. The opening 3170 has two long sides 3171 , 3173 , two short sides 3172 , 3174 , and four rounded corners 3175 . The two long sides 3171 , 3173 are opposite to each other, and the two short sides 3172 , 3174 are located between the two long sides 3171 , 3173 . The four rounded corners 3175 are respectively connected between the two short sides 3172, 3174 and the two adjacent long sides 3171, 3173. In some embodiments, part of the included angle between two adjacent edges is a right angle, and the rest of the included angle between two adjacent edges is not a right angle.

In some embodiments, at least one opening of the light blocking layer is non-axisymmetric to its corresponding optical axis, and the opening includes more than four edges. For example, as shown in FIG. 9 , the opening 4170 of the light blocking layer 417 is non-axisymmetric to the optical axis passing through itself. The opening 4170 is octagonal and has two long sides 4171 , 4173 , two short sides 4172 , 4174 , and four connecting sides 4175 . The four connecting sides 4175 are connected between each two long sides 4171 , 4173 and two adjacent short sides 4172 , 4174 .

In addition, the quantity and position of the light blocking layers are not limited by the above embodiments.

Referring to FIG. 10 , it shows a cross-sectional view of the image capturing component 5 of some embodiments of the present invention. In FIG. 10 , elements similar to those in FIG. 5 will be given the same reference numerals, and their features will not be described again to simplify the description.

The image capture component 5 is different from the image capture component 2 shown in FIG. 5 in that the image capture component 5 further includes a light blocking layer 527 . For convenience of description, the light blocking layer 217 is replaced by the first light blocking layer, and the light blocking layer 527 is replaced by the second light blocking layer. The second light blocking layer 527 is directly formed on the surface of the second substrate 121 by coating. The surface of the second light blocking layer 527 is opposite to the surface formed by the third lens array layer 123 . The fourth lens array layer 125 is formed on the second light blocking layer 527 . In some embodiments, the second light blocking layer 527 is farther away from the light sensing unit 150 a and the light sensing unit 150 b than the first light blocking layer 217 .

In some embodiments, the second light blocking layer 527 includes a plurality of light blocking elements, such as a light blocking element 528a and a light blocking element 528b. The light blocking element 528a has an opening 5270a. The opening 5270a is aligned with the optical axis O1. The light blocking element 528b has an opening 5270b. The opening 5270b is aligned with the optical axis O2. In some embodiments, the light blocking layer 527 is made of non-transparent material. Light can pass through the light blocking layer 527 through the openings 5270a and 5270b, but is absorbed or reflected by the light blocking layer 527 .

In some embodiments, some openings of the light blocking layer 527 are non-axisymmetric to their corresponding optical axes. The shape of the opening is associated with the shape of the corresponding image capture element. For example, the opening 5270a of the light blocking layer 527 is non-axisymmetric to the optical axis O1. The opening 5270a is rectangular and has four edges (not shown). In some embodiments, the shape of the opening is similar to the shape of the opening in any of the above-mentioned embodiments.

In some embodiments, openings aligned along the same optical axis have different widths. In some embodiments, the width of the openings farther away from the light sensing unit in one direction is smaller than the width of the openings closer to the light sensing unit in the same direction. For example, the width W5 of the opening 5270a is smaller than the width of the opening 2170a.

Referring to FIG. 11 , it shows a cross-sectional view of the image capturing component 6 of some embodiments of the present invention. The difference between the image capture component 6 and the image capture component 2 shown in FIG. 5 is that the light blocking layer 217 of the image capture component 2 is replaced by the light blocking layer 617 .

In some embodiments, the light blocking layer 617 is directly formed on the first substrate 111 by coating. The light blocking layer 617 includes a plurality of annular light blocking elements, such as a light blocking element 618a and a light blocking element 618b. An opening 6170a is formed in the center of the light blocking element 618a. The opening 6170a is aligned with the optical axis O1. An opening 6170b is formed in the center of the light blocking element 618b. The aperture 6170b is aligned with the optical axis O2. In some embodiments, the light blocking layer 617 is made of non-transparent material. Light can pass through the light blocking layer 617 through the openings 6170a, 6170b, but is absorbed or reflected by the light blocking layer 617.

In some embodiments, some openings of the light blocking layer 617 are non-axisymmetric to their corresponding optical axes. In some embodiments, the shape of the opening is associated with the shape of the corresponding image capture element. In some embodiments, the shape of the opening is similar to the shape of the opening in any of the above-mentioned embodiments.

Since the light blocking layer 617 extends on the surface of the first substrate 111 in a discontinuous manner, the rest of the surface of the first substrate 111 not coated with the light blocking layer 617 can directly contact the first lens array layer 113, and the image capture component The structural strength of 6 is thus enhanced.

Referring to Figures 12 and 13, Figure 12 shows a cross-sectional view of the image capture component 7 of some embodiments of the present invention. FIG. 13 shows a schematic diagram of a light blocking layer 727 of some embodiments of the present invention.

The light blocking element 731a has an opening 732a, and the light blocking element 731b has an opening 732b. The first functional lens 711a, a second functional lens 721a, and the opening 732a are arranged along the same optical axis O1.
