[0038] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0039] like Figure 1 As shown, the present invention provides a method for adjusting a color filter matrix, comprising: S100, S200 and S300;

[0040] S100, determining a first voltage control signal for an upper layer of a color filter matrix and a second voltage control signal for a lower layer of a color filter matrix according to a target mode type, wherein the upper layer of the color filter matrix includes a plurality of identical first matrix units, any of which is obtained by arranging N filters with different electro-optical characteristics in a fixed order, and the lower layer of the color filter matrix includes a plurality of identical second matrix units, any of which is obtained by arranging N filters with different electro-optical characteristics in a fixed order, and the filters of the first matrix units have different electro-optical characteristics from the filters of the second matrix units;

[0041] Optionally, the present invention can be applied to photographic equipment. By executing the present invention, the filtering characteristics of the color filter matrix can be changed according to different scenes, so that the photographic equipment can meet the shooting needs of various scenes without changing the lens. It is relatively convenient and fast, and there is no need to increase the hardware cost. The present invention does not impose any restrictions on this.

[0042] Optionally, the color filter matrix of the present invention can be divided into two layers, such as Figure 2 As shown in the figure, they are the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix. Each layer has multiple units, and each unit has multiple filters (for example Figure 2 4 filters are shown in FIG. 1 ). It should be noted that: for the upper layer up of the color filter matrix or the lower layer bottom of the color filter matrix, each unit thereof is the same, but any unit includes N filters with different electro-optical characteristics, which can be specifically reflected in different materials. That is, the electro-optical characteristics of filters made of different materials are different, and the present invention does not limit this.

[0043] For example, Figure 2 As shown, each unit unit is composed of 4 filters of different materials. The materials of the 4 filters of each unit unit of the upper layer up of the color filter matrix are: A, B, C and D, that is to say, the entire upper layer up of the color filter matrix is ​​composed of filters of four materials A, B, C and D arranged according to a fixed rule. Similarly, the materials of the 4 filters of each unit unit of the bottom layer of the color filter matrix can be: A', B', C' and D'. Therefore, the upper layer up of the color filter matrix and the bottom layer of the color filter matrix are each composed of 4 materials, but the materials are not the same. Specifically, the upper layer up of the color filter matrix can select the "lower wavelength cutoff material", and the bottom layer of the color filter matrix can select the "upper wavelength cutoff material". Therefore, the voltage control signals subsequently received by the upper layer up of the color filter matrix and the bottom layer of the color filter matrix are also different, and the present invention does not limit this.

[0044] Optionally, as described above, the upper layer up of the color filter matrix can select the "lower wavelength cutoff material", and the lower layer bottom of the color filter matrix can select the "upper wavelength cutoff material". Therefore, after the light passes through the filtering of the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix, the light of a certain wavelength range can be filtered out. When necessary, it is only necessary to apply a voltage to change the filtering characteristics of the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix to filter out light of different wavelength ranges to meet the needs of different scenes, and the present invention is not limited to this.

[0045] Optionally, the target mode type of the present invention can be Figure 2 The present invention can pre-set different target mode types for different scenes according to actual needs, such as night scene mode, portrait mode and landscape mode, etc., and the present invention does not limit this.

[0046] Optionally, different filtering effects are required for different scenes, that is, different target mode types need to control the color filter matrix to adjust to the corresponding filtering characteristics. The filtering characteristics of the color filter matrix are directly related to the filtering characteristics of the filter inside it, and a certain voltage needs to be applied to the filter to adjust the filtering characteristics of the filter. Therefore, the present invention needs to determine what kind of voltage to apply to the filter according to the target mode type, that is, determine the first voltage control signal and the second voltage control signal.

[0047] For example, in some optional embodiments, the S100 includes:

[0048] According to the target mode type, the first voltage control signal for the upper layer of the color filter matrix and the second voltage control signal for the lower layer of the color filter matrix are queried and determined from a pre-calibrated signal correspondence relationship, wherein the signal correspondence relationship records the first voltage control signal and the second voltage control signal corresponding to different target mode types, the first voltage control signal includes N first sub-signals corresponding to the N filters of the first matrix unit, and the second voltage control signal includes N second sub-signals corresponding to the N filters of the second matrix unit.

[0049] Optionally, the signal correspondence relationship mentioned in the present invention can be obtained through continuous experiments to determine the first voltage control signal and the second voltage control signal corresponding to various target mode types, and then the corresponding correspondence relationship is calibrated and recorded for direct query when needed. The present invention does not impose any restrictions on this.

[0050] S200, applying a voltage of corresponding intensity to each filter in the upper layer of the color filter matrix according to the first voltage control signal, so as to adjust the filtering characteristics of each filter in the upper layer of the color filter matrix, wherein the voltages applied to filters with the same electro-optical characteristics are the same, and the voltages applied to filters with different electro-optical characteristics are different;

[0051] Optionally, the first voltage control signal of the present invention matches the corresponding voltage, and after the voltage is applied to the filter, its own filtering characteristics will change, and the present invention does not impose any limitation on this.

[0052] For example, in some optional embodiments, the S200 includes:

[0053] According to the N first sub-signals in the first voltage control signal, a first voltage group is applied to each of the first matrix units on the upper layer of the color filter matrix to adjust the filtering characteristics of each filter of each first matrix unit, wherein the first voltage group includes N voltage sub-signals with different intensities, one voltage sub-signal is applied to each filter, and the same voltage sub-signal is applied to filters at the same position in different first matrix units.

[0054] Optionally, from the perspective of each first matrix unit, each first matrix unit is applied with the same first voltage group. However, from the perspective of each filter inside the first matrix unit, the voltage sub-signal applied to each filter is different.

[0055] For example, Figure 2 As shown, after determining the first voltage control signal and the second voltage control signal, the mode switching unit sends the two control signals to the power supply network. The power supply network then applies corresponding voltages to the color filter matrix according to the two control signals. For example, Figure 2 The power supply network in the color filter matrix supplies power to the four filters (assuming they are named as: CF 00 CF 01 CF 10 and CF 11 ) apply V 00 、V 01 、V 10 and V 11 Four voltages. That is, for any unit in the upper layer of the color filter matrix: CF 00 Apply V 00 , C.F. 01 Apply V 01 , C.F. 10 Apply V 10 , C.F. 11Apply V 11 , the present invention does not limit this.

[0056] S300. According to the second voltage control signal, a voltage of corresponding intensity is applied to each filter in the lower layer of the color filter matrix to adjust the filtering characteristics of each filter in the lower layer of the color filter matrix, wherein the voltages applied to filters with the same electro-optical characteristics are the same, and the voltages applied to filters with different electro-optical characteristics are different.

[0057] For example, in some optional implementations, the S300 includes:

[0058] According to the N second sub-signals in the second voltage control signal, a second voltage group is applied to each second matrix unit in the lower layer of the color filter matrix to adjust the filtering characteristics of each filter of each second matrix unit, wherein the second voltage group includes N voltage sub-signals with different intensities, one voltage sub-signal is applied to each filter, and the same voltage sub-signal is applied to filters at the same position in different second matrix units.

[0059] Optionally, from the perspective of each second matrix unit, each second matrix unit is applied with the same second voltage group. However, from the perspective of each filter inside the second matrix unit, the voltage sub-signal applied to each filter is different.

[0060] For example, the power supply network provides power to four filters (assuming they are named as: CF 00 `, CF 01 `, CF 10 ` and CF 11 `) Apply V 00 `、V 01 `、V 10 ` and V 11 `Four voltages. That is, for any unit at the bottom of the color filter matrix: CF 00 `Apply V 00 `, CF 01 `Apply V 01 `, CF 10 `Apply V 10 `, CF 11 `Apply V 11 `, the present invention does not limit this.

[0061] Optionally, in some optional embodiments, before S100, the method further includes: step 1.1 and step 1.2;

[0062] Step 1.1, obtain the current imaging picture;

[0063] Step 1.2: Determine the corresponding target mode type according to the imaging picture.

[0064] Optional, such as Figure 2 The photosensitive imaging unit (English name: Sensor) shown can obtain a corresponding imaging picture after obtaining the light filtered by the color filter matrix. The photosensitive imaging unit can feed back the imaging picture to the mode switching unit so that the mode switching unit can determine the corresponding target mode type according to the imaging picture. That is, the mode switching unit can automatically select a suitable target mode type according to the imaging picture fed back by the photosensitive imaging unit, and the present invention does not limit this.

[0065] Optionally, as described above, the mode switching unit may select a suitable target mode type. To improve the applicability of the present invention, the present invention also supports manual adjustment of the target mode type by the user.

[0066] For example, in some optional embodiments, after step 1.2, the method further includes:

[0067] The target mode type is adjusted according to the user's adjustment instruction.

[0068] Optionally, the user can manually adjust the target mode type based on the device's automatic selection of the target mode type according to their own needs and actual scenario requirements until the target mode type reaches the user's goal, and the present invention is not limited to this.

[0069] Of course, the present invention can also support a pure manual mode, that is, the target mode type is completely manually input by the user without an automatic selection process.

[0070] That is, in some optional implementation manners, before S100, the method further includes:

[0071] Gets the target mode type of the user input.

[0072] Optionally, in order to further illustrate the solution of the present invention, the following examples are provided to clearly describe the above embodiments.

[0073] First, use the mode switching unit to select a target mode type, and adjust the power supply mode of the power supply network according to the target mode type. The power supply network is divided into two layers: the upper layer is used to adjust the upper layer up of the color filter matrix, and the lower layer is used to adjust the lower layer bottom of the color filter matrix. Taking the upper layer up of the color filter matrix as an example, the upper layer up of the color filter matrix is ​​composed of multiple repeating units, each unit contains 4 filters (Color Filter, CF). When the color filter matrix needs to be changed, the voltage modulation signal is first input to each unit of the color filter matrix, and four voltage signals need to be output each time: V 00 、V 01 、V 10 and V 11 The 4 CFs are given to each unit respectively. At the same time, the CFs at the corresponding positions in each unit are made of the same material, so when receiving voltage regulation, the electro-optical characteristic response of each unit of the color filter matrix is ​​the same, and the corresponding light filtering effect is also the same. Thus, a CFA up with new optical characteristics is formed. The modulation principle of the bottom layer of the color filter matrix is ​​the same as that of the CFA up, but the response characteristics of the two materials to voltage are different. The material of each unit of the bottom layer of the color filter matrix is ​​an upper wavelength cutoff material, that is, for a certain voltage signal, only light bands below a certain wavelength can pass through, and CFA up can only pass through light bands above a certain wavelength. The combination of the two can only pass through light bands within a certain wavelength range.

[0074] The input of the mode switching unit is the user's instruction or the feedback parameter of the Sensor imaging in the current environment, and the output is the target mode type. The main function is for the user to select the target mode type to be adjusted according to the current scene or Sensor imaging effect. For example, when the vehicle is driving in a night scene, the overall brightness is dim, and there are no more color scenes, using a color filter matrix with a bayer (Bayer array) type of RCCC or RCCB can make the picture brighter; when the picture is in a clear daytime state, the overall brightness and color elements are more, and the use of conventional bayer types, such as RGGB or BGGR, can achieve better picture effects; when only picture brightness and contour information are needed, but no color information is required, mono can be used; when the scene is dark and more contour and color information is required, the bayer type can be used to obtain RGB data and IR data to enhance the picture effect together. It should be noted that the above-mentioned bayer, RCCC, RCCB, RGGB, BGGR, mono, RGBIR, RGB and IR are all well-known concepts in the art, and the present invention does not describe this in detail. Please refer to the relevant description of the art for details.

[0075] The input of the power supply network is the target mode type, and the output is the voltage for the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix. Its main function is to convert the target mode type into the voltage for the unit, so as to modulate the unit to the required bayer type. Users can adjust the bayer type of CFA by themselves, or use the established standard filter block.

[0076] like Figure 3 As shown, there are standard filter blocks between the target mode type and the voltage: R, G, B, C and Y. For example: When the user needs to modulate the bayer type to RGGB (i.e. CF 00 Position is R, CF 01 Position is G, CF 10 Position is G, CF 11 Position B). First select CF 00 , and then click the R button, the CF in the upper layer of the color filter matrix up and the lower layer of the color filter matrix bottom 00 A pre-calibrated voltage will be applied at the same time. Under the action of this voltage: the CF on the upper layer of the color filter matrix 00 The position can only pass the light band above 650nm, the color filter matrix bottom layer CF 00 The position can only pass the light band below 700nm, thus achieving CF in each unit 00 The wavelength passed by the position is limited to 650nm~700nm. Then select CF 01 , click the G button. Similarly, the CF in the upper layer of the color filter matrix up and the lower layer of the color filter matrix bottom 01 The position will be modulated by a pre-calibrated voltage to only pass the 500nm~550nm light band. Similarly, CF 10 Modulated to pass only the 500nm~550nm optical band, CF 11 It is modulated to pass only the 450nm~480nm light band.

[0077] In addition, the present invention can also support the user to manually adjust the CF in the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix.

[0078] The input of the unit is voltage. Different voltages act on the CF in each unit, so that different CFs produce different light filtering effects, which are used for the subsequent sensor imaging. The voltage acts on the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix at the same time, and the unit positions of the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix are completely corresponding. Combined with the above example, the filter unit composed of the first unit in the upper left corner of the upper layer up of the color filter matrix and the lower layer bottom of the color filter matrix is ​​equivalent to: 650nm~700nm (R), 500nm~550nm (G), 500nm~550nm (G), 450nm~480nm (B), that is, the equivalent implementation of the RGGB filter is realized, and the cutoff range adjustment can be adjusted relatively freely according to environmental changes.

[0079] like Figure 4 As shown, the corresponding voltage can control the passable wavelength band of different wavelength cut-off materials, thereby realizing the filtering regulation of CF.

[0080] The input of the sensor is the light regulated by the unit, and the output of the sensor is the image after receiving the light. Its main function is to clearly image the current scene for user viewing, processing and effect feedback.

[0081] The input of the mode switching unit is the sensor imaging effect, and the output is the target mode type. The user adjusts the imaging mode according to the current imaging effect to achieve the most satisfactory imaging effect for the user.
