The electronic equipment of this computer etc..
External photogenerated can be improved the transmitted light of light receiving efficiency by lenticule 11.Specifically, after lenticule 11 is set to
On the photosensitive element for the photosensitive unit 12 stated, so that exterior light is incident on each photosensitive element via each lenticule 11.It is logical
The setting lenticule 11 on photosensitive element is crossed, so that the photosensitive area of photosensitive element is not determined by the opening area of photosensitive element,
But it is determined by the surface area of lenticule 11.Therefore, exterior light is formed by transmitted light after lenticule 11, relative to outside
Light and light receiving efficiency improve.In other words, after being provided with lenticule, the photosensitive element under the luminous intensity of same exterior light
Stronger electric signal can be generated, thus, it is possible to improve image quality.
As shown in figure 3, lenticule in the prior art is all coloured, and colored filter is needed to carry out exterior light
It filters, lenticule 11 has filtering functions, and specifically lenticule 11 for example carries out the filter of frequency range locating for red light to exterior light
The optical filtering of frequency range locating for the optical filtering of frequency range locating for light, green light or blue light.It can stop in addition to the color of lenticule in this way
The light of other color corresponding wavelengths causes the luminous intensity after lenticule transmits that can weaken, to be formed by the intensity phase of light
15% or so are weakened for exterior light.The light of remitted its fury is incident on photosensitive element, therefore photosensitive element is relative to exterior light
Photoelectric conversion efficiency can not be increased to 85% or more.
In contrast, in embodiments of the present invention, as shown in figure 4, lenticule 11 is made of white lens, and removing
