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.

At present, the imaging element in the electronic Device is mainly a CMOS (Complementary Metal-Oxide-Semiconductor) chip or a CCD (Charge-coupled Device) chip. Based on the principle that the RGB three primary colors can be mixed according to different proportions to restore various colors in the world, a layer of optical filter is covered above a CMOS or CCD chip and comprises three colors of Red (Red, R), Green (Green, G) and Blue (Blue, B). The filters are arranged in one-to-one correspondence with the pixel cells, and the color of the filter is set to coincide with the color of the corresponding pixel cell.

In the using process, in order to enable the electronic device to achieve a good imaging effect, different filter arrangement arrays can be set in different shooting environments, for example, different illumination environments. Generally, in a bright environment where light is sufficiently strong, the arrangement of the filter units is different from that in a relatively dark lighting environment. However, in the related art, only one fixed filter unit arrangement array can be set, which results in that the electronic product can only satisfy the definition of imaging under one illumination condition, and such setting limits the use scene of the electronic device and also reduces the visual experience of users under different light environments.

In view of the above technical problem, the present disclosure provides a photosensitive element, which includes an optical filter, where the optical filter includes a plurality of optical filter units, and the plurality of optical filter units are connected to a driving circuit. The plurality of filter units are arranged to display different colors according to different electric signals input by the driving circuit so as to form different filter unit arrays. The photosensitive element of this disclosure is through setting up a plurality of filtering units as and connecting in advance with drive circuit for a plurality of filtering units can change into different colours according to the different electrical signals of drive circuit input, in order to form different filtering array, can reach the purpose that clearly shows the image. When the photosensitive element arranged in this way is used for electronic equipment, when the electronic equipment is used in different light environments, for example, under a bright light environment or a dark light environment, the image can be clearly displayed by adjusting the color development of the optical filter, so that the use scenes of the electronic product are increased, and the electronic product can have a good image display function under various light environments.

When the photosensitive element of the present disclosure is used in an electronic device, in general, an instruction may be sent to a driving circuit connected to an optical filter through an ISP (Image Signal Processing), and the driving circuit receives the instruction and outputs electric signals corresponding to the instruction to a plurality of optical filter units of the optical filter, so as to activate the optical filter units in the optical filter to display colors to form a corresponding optical filter unit array. As shown in fig. 1, fig. 1 is a block diagram illustrating an operation principle of a photosensitive element according to an exemplary embodiment. In use of the electronic device, it may be arranged that the filter unit array is autonomously selected by a user instruction, and for example, three kinds of filter unit arrays, which are an RGGB Bayer array, a four-in-one Bayer (Quad Bayer) array, and an RGBW array, may be arranged.

In the exemplary embodiment of the present disclosure, generally, in an RGGB bayer array, three primary colors of Red (Red, R), Green (Green, G), and Blue (Blue, B) may be displayed on a filter, and the three primary colors are adjacently disposed, so that generation of a false color may be reduced, colors and details closer to a real scene may be restored, and a picture may be displayed when light is sufficient. In the four-in-one Bayer array, the light filtering units above the four 2 x 2 arranged photosensitive pixels display the same color, so that the light sensing capacities of the four pixels can be integrated, the noise is reduced, and the four-in-one Bayer array is suitable for dark light conditions. The RGBW array adds W white sub-pixels on RGB three primary colors, and becomes a four-color type pixel design, so that the light transmittance of the liquid crystal panel can be improved, when the picture with the same brightness is displayed, the power consumption is lower, and under the condition of the same power consumption, the brightness is greatly improved, so that the picture level is clearer, and the picture is more transparent. The display images presented by different filter unit arrays have different effects.

In an exemplary embodiment of the present disclosure, the plurality of filter units are connected to the driving circuit and configured to display different colors according to different electrical signals input by the driving circuit. In exemplary embodiments of the present disclosure, the filter may be an electrochromic filter. The electrochromic filter may be connected to a drive circuit, for example, by pressurizing the filter with the drive circuit, so that the electrochromic filter produces different colors according to different voltages applied thereto. In some embodiments, the driving circuit may also send an electrical signal to the filter, so that the electrochromic filter generates different colors according to different voltages applied to the electrochromic filter. The plurality of light filtering units are connected with the driving circuit, and the display color can be changed according to the electric signals of the driving circuit, so that the driving circuit can transmit the electric signals to each light filtering unit by making different instructions to the driving circuit, and the color of each light filtering unit is changed, thereby finishing the purpose of changing the display array by the light filter. For example, the color filter can display different colors according to different electric signals by being connected with the driving circuit, so that the color of the color filter can be changed, the color filter can be set into different arrangement modes by changing the color of the color filter, and imaging can be clearly displayed under different light brightness.

In an exemplary embodiment of the present disclosure, the material of the optical filter includes a color-changeable photosensitizer. Generally, the optical filter may be glass, and the embodiments of the present disclosure may achieve the purpose that the optical filter can change the display color by adding a color-changeable photosensitizer during the manufacturing process of the optical filter.

In an exemplary embodiment of the present disclosure, when the driving circuit inputs a first electrical signal, the plurality of filter cells display a first color according to the first electrical signal to form a first filter cell array. For example, when the sensitivity is less than the first threshold, the driving circuit may input a first electrical signal to arrange the plurality of filter units in the first filter unit array. The first filter cell array may be an RGGB bayer array.

In an exemplary embodiment of the present disclosure, when the driving circuit inputs the second electric signal, the plurality of filter cells display the second color according to the second signal to form the second filter cell array. For example, when the sensitivity is greater than the first threshold, the driving circuit may input a second electrical signal to arrange the plurality of filter units in the second filter unit array. The second filter unit array may be a four-in-one bayer array.

In an exemplary embodiment of the present disclosure, the light sensing element of the present disclosure further includes a light sensing pixel array. The filters may be arranged to overlie an array of photosensitive pixels, wherein filter cells in different arrays of filter cells overlie different photosensitive pixels. In the photosensitive element disclosed by the disclosure, the filtering units of the optical filter can be arranged in one-to-one correspondence with the photosensitive pixels, namely, each filtering unit is arranged in one-to-one correspondence with one photosensitive pixel, so that the display of the whole picture can be completed through the color development array arrangement of the filtering units more accurately. In the exemplary embodiment of the present disclosure, the driving circuit of the filtering unit may be packaged together with the driving circuit of the photosensitive pixel, or may be configured to be independent of each other, which may be sufficient for the purpose.

In an exemplary embodiment of the present disclosure, the ambient light condition includes a sensitivity less than a first threshold, the array of filter cells is a bayer array; the light filtering units in the light filtering unit array cover one light sensing pixel, and color filters displayed by three adjacent light filtering units are three primary colors. It should be noted that, when the photosensitive element of the present disclosure is applied to an electronic device with a display function, such as a mobile phone, a tablet, or a notebook computer, the corresponding electronic device has an environment light condition capable of determining an application scene at that time, that is, the electronic device is capable of determining whether the application scene is bright light or dim light at that time. Generally, the sensing, determining and instructing functions of the electronic device are accomplished by sending an electrical signal through an integrated circuit, for example, the sensed light can be converted into an electrical signal, and the instruction represented by the electrical signal can be determined through analyzing the electrical signal, so as to perform corresponding execution. In the present disclosure, the ambient light condition determined by the electronic device may also be transmitted by means of an electrical signal. Generally, the determination of ambient light conditions by the electronic device can be ultimately quantified as a sensitivity value.

Iso (international Standardization organization) sensitivity is an international uniform index that measures the speed standard of film sensitivity used by conventional cameras, and reflects the speed of film when sensitive. In a conventional film camera, ISO represents the standard of the light sensing speed, and in an electronic device with a shooting function, ISO definition is the same as that of a film, and represents the light sensing speed of a light sensing element such as a CCD or a CMOS, and the higher the ISO value is, the stronger the light sensing capability of the light sensing material is. In the electronic equipment with the shooting function, the number of the light sources and the numerical value of the picture brightness can be changed by adjusting the equivalent sensitivity. Therefore, the sensitivity is also a value that indirectly controls the brightness of the picture. Generally speaking, the higher the sensitivity, the coarser the grains of the negative film, the poorer the effect after amplification, and the lower the reference ISO, the higher the required exposure amount for the electronic equipment with shooting function to also use this ISO value to mark the exposure used by the photometric system. However, since an electronic device having an imaging function is different from a general camera, there is a problem that exposure is required to some extent, and sensitivity is high. This is equivalent to that the film has a certain sensitivity, and for the convenience of understanding of the user, the sensitivity (or sensitivity to light) of the CCD of the electronic device is generally equivalently converted into the sensitivity value of the conventional film, so the electronic device also has the term "equivalent sensitivity". For electronic devices, no film is used, but the intensity of incident light is sensed by a photosensitive device CCD or CMOS and associated electronics. The concept of ISO sensitivity has been introduced in order to unify the units of measure with the film used by conventional cameras.

In the exemplary embodiment of the present disclosure, the first threshold may be specifically set by a program, for example, may be set to 200, that is, when the sensitivity is considered to be less than 200, the ambient light condition is bright light, and the filter cell array is a bayer array; the light filtering units in the light filtering unit array cover one light sensing pixel, and color filters displayed by three adjacent light filtering units are three primary colors. Fig. 2 illustrates a bayer array arrangement according to an exemplary embodiment. As shown in fig. 2, when the sensitivity is less than 200, the filter unit may operate in an RGGB bayer array, and since the three primary color pixels are all adjacent, the generation of false colors can be reduced, and the color and detail closer to the real scene can be restored, i.e., the probability of color guessing error is lower. In an RGGB bayer array, each filter cell corresponding to a photosensitive pixel displays a color, for example, red, green, or blue, and two adjacent filter cells display different colors.

In an exemplary embodiment of the present disclosure, the ambient light condition includes a sensitivity greater than or equal to a first threshold, the filter cell array is a four-in-one bayer array; the filter units in the filter unit array cover 2 × 2 photosensitive pixels, and the filter units covering 2 × 2 photosensitive pixels display the same color. Fig. 3 is a schematic diagram illustrating an arrangement of a four-in-one bayer array according to an exemplary embodiment, and as shown in fig. 3, when the light sensitivity is greater than 200, the filter unit operates as a four-in-one Quad bayer array, and the same color filter unit covers the four photosensitive pixels, so that the photosensitive capabilities of the four photosensitive pixels can be integrated, noise easily generated in dark light can be greatly reduced, the photosensitive performance can be improved, and better image quality can be obtained. That is, in the exemplary embodiment of the present disclosure, when the ambient light condition is bright light, 2 × 2 is taken as a pixel unit, and the filter unit corresponding to each photosensitive pixel in the same pixel unit displays the same color.

It should be noted that the setting of the first threshold value to 200 in the embodiments of the present disclosure is merely an example, and may be specifically set as needed in actual manufacturing, and the present disclosure is not particularly limited.

Based on the same concept, the embodiment of the present disclosure further provides a photosensitive control method, which is applied to a photosensitive element, where the photosensitive element includes an optical filter, the optical filter includes a plurality of optical filter units, the plurality of optical filter units are connected to the driving circuit, and the photosensitive control method includes: determining a target electrical signal; controlling the driving circuit to input the target electric signals, and driving the plurality of light filtering units to display corresponding colors to form a target light filtering unit array; the plurality of filter units display different colors to form different filter unit arrays. The photosensitive control method disclosed by the invention can maximally exert the performance of the photosensitive element by adjusting the display color of the optical filter so as to obtain display pictures with different effects.

FIG. 4 is a flow chart illustrating a method of photosensitive control according to an exemplary embodiment. In the present disclosure, when the related apparatus employs the photosensitive element described above in the embodiment of the present disclosure, the photosensitive control may be performed by the following steps as shown in fig. 4:

in step S11, a target electrical signal is determined.

In step S12, the control drive circuit inputs the target electric signal, drives the plurality of filter cells to display corresponding colors, and forms a target filter cell array.

In the exemplary embodiment of the present disclosure, first, a target electrical signal is determined, the driving circuit is controlled to input a corresponding electrical signal, different filter cell arrays are matched according to different received electrical signals, and then the plurality of filter cells are controlled to display corresponding color filters, so as to form the filter cell array.

In the exemplary embodiment of the present disclosure, as described above, the electric signal transmitted by the driving circuit may be determined by the ISP transmitting an instruction. The ISP may indicate the drive circuit differently depending on the user's discretion or the ambient light conditions in which the electronic device is used, i.e. the ISP determines the target electrical signal of the drive circuit. Fig. 5 is a flowchart illustrating a photoreception control method according to another exemplary embodiment. As shown in fig. 5, the photosensitive control method of the present disclosure may include the steps of:

in step S21, the sensitivity is determined according to the ambient light conditions.

In step S22, if the sensitivity is less than the first threshold, the first electric signal is determined as the target electric signal.

In step S23, the control driving circuit inputs a first electrical signal to drive the plurality of filter cell arrays to display a first color, thereby forming a first filter cell array.

In the present disclosure, it may be set that the driving circuit outputs the first electrical signal if it is determined that the sensitivity of the current ambient light condition is less than the first threshold. In the shooting process of the electronic device, there is a process of: after the camera photometric system senses the light brightness, three shooting parameters, namely a shutter, an aperture and sensitivity, are given, generally speaking, the aperture is not changed, and the parameters of the shutter and the sensitivity are changed. The present disclosure selects the sensitivity as a criterion for determining the ambient light condition, and for example, when the sensitivity is less than 100, the ambient light condition at this time may be considered as a bright light condition, and the first electrical signal may be output to control the filter to display the RGGB bayer array. It may be further configured that the driving circuit outputs the second electrical signal if it is determined that the sensitivity of the current ambient light condition is greater than the first threshold. For example, when the sensitivity is greater than 100, the ambient light condition may be considered as a dark light condition, and the second electrical signal may be output to control the filter to display the four-in-one bayer array.

In the exemplary embodiment of the present disclosure, the first threshold may be specifically set by a program, for example, may be set to 200, that is, when the sensitivity is considered to be less than 200, the ambient light condition is bright light, and the filter cell array is a bayer array; the light filtering units in the light filtering unit array cover one light sensing pixel, and color filters displayed by three adjacent light filtering units are three primary colors. As shown in fig. 2, when the sensitivity is less than 200, the filter unit may operate in an RGGB bayer array, and since the three primary color pixels are all adjacent, the generation of false colors can be reduced, and the color and detail closer to the real scene can be restored, i.e., the probability of color guessing error is lower. In an RGGB bayer array, each filter cell corresponding to a photosensitive pixel displays a color, for example, red, green, or blue, and two adjacent filter cells display different colors.

In the present disclosure, each filter cell in the array of filter cells may be controlled to cover one photosensitive pixel, and the colors displayed by adjacent three filter cells are controlled to three primary colors, forming a first array of filter cells. I.e. the first color may be the three primary colors R, G, B, the first filter cell is arranged as an RGGB bayer array.

The optical filter of the present disclosure may present different arrangement of the optical filter unit array according to different received electrical signals, and fig. 6 is a flowchart illustrating a light sensing control method according to another exemplary embodiment. As shown in fig. 6, the photosensitive control method of the present disclosure may further include the following steps:

in step S31, the sensitivity is determined according to the ambient light conditions.

In step S32, if the sensitivity is greater than or equal to the first threshold, it is determined that the drive circuit outputs the second electric signal as the target electric signal.

In step S33, the control driving circuit inputs a second electrical signal to drive the plurality of filter cell arrays to display a second color, thereby forming a second filter cell array.

In the present disclosure, it may be configured that 2 × 2 filter cells in the control filter cover 2 × 2 photosensitive pixels, and 2 × 2 filter cells that control the cover 2 × 2 photosensitive pixels display the same color, forming a second filter cell array. That is, the second filter array may be a four-in-one bayer array.

It should be noted that, in the sensitization control method of the present disclosure, the first signal is different from the second signal, and the second filter cell array is different from the first filter cell array, so that the filter cell array can be changed under the driving of different electric signals to form different image displays. The present disclosure is not limited to two different electrical signals and filter cell arrays, and in actual manufacturing, a plurality of different electrical signals may be included, corresponding to a plurality of different filter cell arrays.

In an exemplary embodiment of the present disclosure, the ambient light condition includes a sensitivity greater than or equal to a first threshold, the filter cell array is a four-in-one bayer array; the filter units in the filter unit array cover 2 × 2 photosensitive pixels, and the filter units covering 2 × 2 photosensitive pixels display the same color. As shown in fig. 3, when the sensitivity is greater than 200, the filter unit operates in a Quad bayer array, and the same color filter unit covers all the four photosensitive pixels, so that the photosensitive capabilities of the four photosensitive pixels can be integrated, noise easily generated in dark light can be greatly reduced, the photosensitive performance can be improved, and better image quality can be obtained. That is, in the exemplary embodiment of the present disclosure, when the ambient light condition is bright light, 2 × 2 is taken as a pixel unit, and the filter unit corresponding to each photosensitive pixel in the same pixel unit displays the same color.

The photosensitive control method disclosed by the invention can control the optical filter to work in an RGGB Bayer array when light is sufficient, and at the moment, because the three primary color pixels are adjacent, the generation of false color can be reduced, the color and the detail which are closer to a real scene can be restored, namely, the error probability of color guessing is lower. When light is insufficient, the optical filter is controlled to work in a Quad Bayer array, the same color filter covers the four pixels, the light sensing capability of the four pixels can be integrated, noise easily generated in dark light is greatly reduced, the light sensing performance is improved, and better image quality is obtained.

In the exemplary embodiment of the present disclosure, the optical filter may be configured as an optical filter that can display electrochromic materials of different colors under the control of an electrical signal, and the optical filter configured in this way may complete the change of display colors by being connected to a driving circuit. When arranging for different arrays, the display color filters of a plurality of filter units are different, and then the electric signals of the color filters matched with the array are input through the control circuit to control the plurality of filter units to display corresponding colors, and the change of the display colors of the optical filter is completed.

Based on the same conception, the embodiment of the disclosure also provides a photosensitive control device. The light filter can be arranged to be the light filter which can display electrochromic materials with different colors under the control of an electric signal, and the light filter arranged in the way can be connected with the driving circuit to finish the change of the display color. When arranging for different arrays, the display color filters of a plurality of filter units are different, and then the electric signals of the color filters matched with the array are input through the control circuit to control the plurality of filter units to display corresponding colors, and the change of the display colors of the optical filter is completed.

The sensitization controlling means of this disclosure includes: the determining unit is used for determining the electric signal currently input by the driving circuit and determining the filter unit array matched with the electric signal; and the control unit is used for controlling the plurality of filtering units to display corresponding colors to form a filtering unit array. The photosensitive control device disclosed by the invention can perfectly adapt to bright and dark scenes by adjusting the optical filter, the performance of the photosensitive element is maximized, and excellent image quality in bright and dark environments is obtained.
