Description
Technical Field
The present disclosure relates to the field of image acquisition technologies, and in particular, to a color image acquisition device and an electronic device.
Background
At present, a camera in a mobile phone is generally not independently arranged, but arranged below a screen of the mobile phone, or arranged on the same side of the mobile phone with the screen.
In order to protect the screen, a film may be attached to the screen, which covers the front camera, or in order to protect the camera alone, a film may be attached to the camera, which also covers the front camera. The attached film is generally yellow, the transmittance of the yellow film to blue light is low, so that more green light and red light can penetrate through the film to reach the color filter layer, and less blue light can penetrate through the film to reach the color filter layer, so that less blue light collected by the camera is easy to cause color cast.
As shown in fig. 1, 2, and 3, in the related art, the ratio of the number of photoelectric conversion units corresponding to the red filter R, the number of photoelectric conversion units corresponding to the green filter G, and the number of photoelectric conversion units corresponding to the blue filter B of the camera is 1:2:1, that is, 2 photoelectric conversion units receive green light, 1 photoelectric conversion unit receives red light, and 1 photoelectric conversion unit receives blue light in every 4 photoelectric conversion units.
And because the yellow film on the light incident side of the lens has low transmittance to blue light, relatively more green light and red light can penetrate through the film to reach the color filter layer, and relatively less blue light can penetrate through the film to reach the color filter layer. Based on the structures shown in fig. 1, fig. 2, and fig. 3, 3 photoelectric conversion units in every 4 photoelectric conversion units can receive no blue light, and only 1 photoelectric conversion unit can receive blue light, specifically, only half of the photoelectric conversion units in every two rows can receive blue light, and then only 1/4 photoelectric conversion units can receive blue light.
This further results in that the intensity of the electric signals generated by the plurality of photoelectric conversion units based on blue light is relatively low, while the intensity of the electric signals generated by the plurality of photoelectric conversion units based on red light and green light is relatively high, easily causing color shift of the finally generated image, particularly, the color blue of the image display is less.
SUMMERY OF THE UTILITY MODEL
The present disclosure provides a color image capturing device and an electronic device, so as to solve the problem in the related art that an image generated by the color image capturing device has color cast due to the relatively low intensity of an electrical signal generated by a photoelectric conversion unit according to blue light in the color image capturing device.
According to a first aspect of embodiments of the present disclosure, there is provided a color image capturing apparatus including:
a plurality of photoelectric conversion units for converting the received optical signals into electrical signals;
a filter layer disposed on a light incident side of the plurality of photoelectric conversion units;
the filter layer comprises a red filter, a green filter and a blue filter, the number of the photoelectric conversion units corresponding to the blue filter is greater than 1 in proportion to the number of the photoelectric conversion units corresponding to the green filter, and the number of the photoelectric conversion units corresponding to the red filter is greater than 1 in proportion.
Optionally, a ratio of the number of the photoelectric conversion units corresponding to the red filter, the number of the photoelectric conversion units corresponding to the green filter, and the number of the photoelectric conversion units corresponding to the blue filter is 1:1: 2.
Optionally, the filter layer comprises a plurality of 2 x 2 array elements,
each 2 x 2 array cell has one of the red filters, one of the green filters and two of the blue filters.
Optionally, the number of photoelectric conversion units corresponding to a unit area of the red filter, the number of photoelectric conversion units corresponding to a unit area of the green filter, and the number of photoelectric conversion units corresponding to a unit area of the blue filter are the same;
the ratio of the area of the blue light filter to the area of the green light filter is greater than 1, and the ratio of the area of the blue light filter to the area of the red light filter is greater than 1.
Optionally, the number of the photoelectric conversion units corresponding to each red filter, the number of the photoelectric conversion units corresponding to each green filter, and the number of the photoelectric conversion units corresponding to each blue filter are the same;
the ratio of the number of the blue filters to the number of the green filters is greater than 1, and the ratio of the number of the blue filters to the number of the red filters is greater than 1.
Optionally, the red filters correspond to the photoelectric conversion units one to one, and/or the green filters correspond to the photoelectric conversion units one to one, and/or the blue filters correspond to the photoelectric conversion units one to one.
According to a second aspect of the embodiments of the present disclosure, there is provided an electronic device including the color image capturing device according to any of the embodiments.
Optionally, the electronic device further comprises:
and the polyimide film layer is arranged on the light incident side of the filter layer.
Optionally, the electronic device further comprises:
a display panel, wherein the color image capture device is disposed below a display area of the display panel.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects:
according to the embodiment of the present disclosure, the ratio of the number of photoelectric conversion units corresponding to the blue filter to the number of photoelectric conversion units corresponding to the green filter is greater than 1, and the ratio of the number of photoelectric conversion units 1 corresponding to the red filter to the number of photoelectric conversion units corresponding to the red filter is greater than 1.
Accordingly, even if less blue light can reach the color filter layer with respect to red light and green light, since there are more photoelectric conversion units corresponding to the blue color filter and fewer photoelectric conversion units corresponding to the green color filter and red color filter.
The proportion of the photoelectric conversion units receiving blue light can be improved, so that the filtering effect of the yellow film on the light inlet side of the color image acquisition equipment on the blue light can be counteracted to a certain degree, and then the intensity of the electric signals generated by the plurality of photoelectric conversion units according to the blue light is less different from the intensity of the electric signals generated according to the red light and the green light, and therefore the phenomenon that the finally generated image has obvious color cast is avoided.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 4 is a schematic block diagram illustrating a color image capture device according to an embodiment of the present disclosure.
Fig. 5 is a schematic cross-sectional view of the color image capturing apparatus shown in fig. 4, taken along CC'. Fig. 6 is a schematic cross-sectional view of the color image acquisition device shown in fig. 4 along DD'.
The color image capturing device in this embodiment may be a stand-alone device, such as a camera, a video camera, or the like, or may be a device disposed in other devices, such as a front camera, a rear camera, or the like in an electronic device, such as a mobile phone, a tablet computer, a wearable device, or the like, where the electronic device may further include a display panel, and the color image capturing device may be disposed outside a display area of the display panel, or may be disposed below the display area of the display panel as an off-screen lens.
As shown in fig. 1, the color image capturing apparatus includes:
a plurality of photoelectric conversion units 1 for converting received optical signals into electrical signals;
a filter layer provided on the light incident side of the plurality of photoelectric conversion units 1;
the filter layer comprises a red filter R, a green filter G and a blue filter B, the number of the photoelectric conversion units 1 corresponding to the blue filter B is greater than 1 in proportion to the number of the photoelectric conversion units 1 corresponding to the green filter G, and the number of the photoelectric conversion units 1 corresponding to the red filter R is greater than 1 in proportion.
In one embodiment, the light may be irradiated on the photoelectric conversion unit after passing through the optical filter layer. For example, as shown in fig. 1, after natural light passes through a red filter, red light is left to be irradiated on the photoelectric conversion unit 1, after natural light passes through a blue filter, blue light is left to be irradiated on the photoelectric conversion unit 1, and after natural light passes through a green filter, green light is left to be irradiated on the photoelectric conversion unit 1.
The electrical signals generated by the photoelectric conversion units receiving different color lights can be transmitted to the processor as signals of different color channels, and the processor processes the signals of each color channel through white balance, color correction, gamma curve adjustment and the like, so as to output an image.
Since current color image capture devices typically have a thin film, such as a polyimide film, which is mostly yellow, the film of this color has a lower transmittance for blue light than for red and green light, resulting in relatively more green and red light being able to pass through the film to the color filter layer and relatively less blue light being able to pass through the film to the color filter layer.
According to the embodiment of the present disclosure, the ratio of the number of photoelectric conversion units corresponding to the blue filter B to the number of photoelectric conversion units corresponding to the green filter G is greater than 1, and the ratio of the number of photoelectric conversion units 1 corresponding to the red filter R is greater than 1.
Accordingly, even if less blue light can reach the color filter layer with respect to red light and green light, since there are more photoelectric conversion units corresponding to the blue color filter and fewer photoelectric conversion units corresponding to the green color filter and red color filter.
For example, as shown in fig. 4, 5, and 6, the ratio of the photoelectric conversion unit 1 corresponding to the red filter R, the photoelectric conversion unit 1 corresponding to the green filter G, and the photoelectric conversion unit 1 corresponding to the blue filter B is 1:1:2, that is, 2 of 4 filters are green filters, 1 is a red filter, and 1 is a blue filter. Specifically to each row of photoelectric conversion units 1, half of the photoelectric conversion units in each row of photoelectric conversion units can receive blue light, so that 1/2 photoelectric conversion units can receive blue light, and the proportion of the photoelectric conversion units receiving blue light is improved compared with the situation that only 1/4 photoelectric conversion units can receive blue light in the prior art.
In view of the above, can improve the proportion of the photoelectric conversion unit that receives the blue light to offset the filtering action of the film that the color image acquisition equipment income light side is yellow to the blue light to a certain extent, and then make a plurality of photoelectric conversion units according to the intensity of the signal of telecommunication that the blue light generated, and the intensity difference of the signal of telecommunication that generates according to ruddiness and green glow is less, thereby avoids the image of final generation to appear obvious colour cast.
Optionally, a ratio of the number of the photoelectric conversion units corresponding to the red filter, the number of the photoelectric conversion units corresponding to the green filter, and the number of the photoelectric conversion units corresponding to the blue filter is 1:1: 2.
In one embodiment, the ratio of the number of photoelectric conversion units corresponding to the red filter to the number of photoelectric conversion units corresponding to the green filter to the number of photoelectric conversion units corresponding to the blue filter may be set to 1:1:2, so that the number of photoelectric conversion units receiving blue light is ensured to be larger than the number of photoelectric conversion units receiving green light and red light, and the generated image is not bluish due to the excessive number of photoelectric conversion units receiving blue light.
Optionally, the filter layer comprises a plurality of 2 x 2 array elements,
each 2 x 2 array cell has one of the red filters, one of the green filters and two of the blue filters.
In one embodiment, each 4 filters may be regarded as a 2 × 2 array unit, and the array unit has one red filter, one green filter and two blue filters, so as to ensure that, for each array unit, the ratio of the number of photoelectric conversion units corresponding to the red filters, the number of photoelectric conversion units corresponding to the green filters and the number of photoelectric conversion units corresponding to the blue filters is 1:1:2, thereby ensuring that an image collected by the photoelectric conversion units corresponding to each array unit is not prone to color shift.
The red filter, the green filter and the blue filter are arranged in the following mode:
in each two rows of photoelectric conversion units, a red filter and a blue filter are sequentially arranged on one row of photoelectric conversion units, and a blue filter and a green filter are sequentially arranged on the other row of photoelectric conversion units.
In one embodiment, for example, as shown in fig. 3 and 4, in every two rows of photoelectric conversion units, a red filter R and a blue filter B are sequentially arranged on one row of photoelectric conversion units, and a blue filter B and a green filter G are sequentially arranged on the other photoelectric conversion unit. Therefore, the optical filters with the same color are prevented from being adjacent to each other, so that the adjacent photoelectric conversion units are prevented from collecting light with the same color, for example, the photoelectric conversion units in the same row or the same column are prevented from collecting light with the same color, and lines with the same color exist in the same row or the same column in the generated image.
Optionally, the number of photoelectric conversion units corresponding to a unit area of the red filter, the number of photoelectric conversion units corresponding to a unit area of the green filter, and the number of photoelectric conversion units corresponding to a unit area of the blue filter are the same;
the ratio of the area of the blue light filter to the area of the green light filter is greater than 1, and the ratio of the area of the blue light filter to the area of the red light filter is greater than 1.
In one embodiment, the number of photoelectric conversion units corresponding to a unit area of the red filter, the number of photoelectric conversion units corresponding to a unit area of the green filter, and the number of photoelectric conversion units corresponding to a unit area of the blue filter may be set to be the same, and the ratio of the area of the blue filter to the area of the green filter is greater than 1, and the ratio of the area of the blue filter to the area of the red filter is greater than 1.
For example, as shown in fig. 1, the ratio of the area of the blue filter to the area of the green filter is equal to 2, and the ratio of the area of the red filter to the area of the blue filter is equal to 2, and since the number of photoelectric conversion units corresponding to each color filter per unit area is the same, the ratio of the number of photoelectric conversion units corresponding to the blue filter to the number of photoelectric conversion units corresponding to the green filter is equal to 2, and the ratio of the number of photoelectric conversion units corresponding to the red filter is equal to 2.
In this embodiment, for the color filter layer, the number of each filter can be set according to the requirement, and the number of the filters with different colors can be different, only the area of the blue filter needs to be ensured, the ratio of the area of the blue filter to the area of the green filter is greater than 1, and the ratio of the area of the red filter to the area of the green filter is greater than 1.
Optionally, the number of the photoelectric conversion units corresponding to each red filter, the number of the photoelectric conversion units corresponding to each green filter, and the number of the photoelectric conversion units corresponding to each blue filter are the same;
the ratio of the number of the blue filters to the number of the green filters is greater than 1, and the ratio of the number of the blue filters to the number of the red filters is greater than 1.
In one embodiment, the number of photoelectric conversion units corresponding to each red filter, the number of photoelectric conversion units corresponding to each green filter, and the number of photoelectric conversion units corresponding to each blue filter may be set to be the same, and the ratio of the number of blue filters to the number of green filters is greater than 1, and the ratio of the number of blue filters to the number of red filters is greater than 1.
For example, as shown in fig. 1, the ratio of the number of blue filters to the number of green filters is equal to 2, and the ratio of the number of red filters to the number of blue filters is equal to 2, and since the number of photoelectric conversion units corresponding to each filter is the same, the ratio of the number of photoelectric conversion units corresponding to the blue filters to the number of photoelectric conversion units corresponding to the green filters is equal to 2, and the ratio of the number of photoelectric conversion units corresponding to the red filters is equal to 2.
In this embodiment, for the color filter layer, the area of each filter can be set as required, the areas of the filters with different colors can be different, and only the number of blue filters needs to be ensured, the ratio to the number of green filters is greater than 1, and the ratio to the number of red filters is greater than 1.
The number of the photoelectric conversion units corresponding to each optical filter is not limited to that shown in fig. 1, and one optical filter corresponds to one photoelectric conversion unit, and may be adjusted as needed, for example, one optical filter corresponds to a plurality of photoelectric conversion units.
The number of the blue filters corresponding to the photosensors, the number of the green filters corresponding to the photosensors, and the number of the red filters corresponding to the photosensors are not limited to 2:1:1 shown in fig. 1, and may be adjusted as needed.
Optionally, the red filters correspond to the photoelectric conversion units one to one, and/or the green filters correspond to the photoelectric conversion units one to one, and/or the blue filters correspond to the photoelectric conversion units one to one.
In one embodiment, the optical filters of each color may be in one-to-one correspondence with the photoelectric conversion units, so that the arrangement of the optical filters in the color filter layer is conveniently set according to the arrangement of the photoelectric conversion units, and the photoelectric conversion units and the optical filters are conveniently aligned by setting the arrangement matrixes of the photoelectric conversion units and the optical filters to be the same.
