Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad invention. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.
Fig. 1 is a flowchart of an image generation method based on an LCD multi-chip component board according to an embodiment of the present invention, where the embodiment is applicable to image generation, and the method may be implemented by an image generation device such as a mobile phone, a smart camera, and the like, and specifically includes the following steps:
and S101, determining a corresponding illumination adjustment strategy in the current image generation scene.
In one embodiment, the image scene is differentially partitioned. The image generation scene refers to a specific scene determined by recognizing or previewing a currently captured image. Illustratively, if it is identified that the preview image has a highlight region, the corresponding image generation scene is a highlight scene, and the corresponding illumination adjustment strategy is a highlight shielding strategy; and if the backlight condition of the preview image is identified, the corresponding image generation scene is a backlight scene, and the corresponding illumination adjustment strategy is a backlight shooting strategy.
In the scheme, different illumination adjustment strategies are set for different scenes.
And S102, controlling the LCD multi-wafer plate to control the intensity of the light rays passing through according to the illumination adjustment strategy, so that the adjusted light rays are induced by an image sensor to generate an image.
In one embodiment, after the illumination adjustment strategy is determined, the intensity of the light passing through the LCD multi-crystal cell is controlled in a mode of controlling the LCD multi-crystal cell to adjust the light, and the adjusted light is induced by the image sensor to generate an image.
In the scheme, the multi-crystal-element-plate-type LED illuminating system comprises a camera and an LCD multi-crystal element plate associated with the camera, wherein the LCD multi-crystal element plate is arranged between a lens of the camera and an image sensor or between the LCD multi-crystal element plate and the image sensor, and the light intensity control under different scenes is realized by controlling the LCD multi-crystal element plate. Specifically, the control method may be, for example, a strong light blocking policy, including: and determining an highlight area in the current shooting picture, and reducing the light passing rate of the highlight area through the LCD multi-crystal element plate. Taking the backlight photographing strategy as an example, the control method includes: determining a shooting target in a current shooting picture; and determining a highlight region corresponding to the shooting target, and reducing the light passing rate of the highlight region through the LCD multi-crystal element plate.
Specifically, the control of the LCD multi-cell panel can adopt different adjustment voltages or currents to control the light passing rate of the corresponding cell in the LCD multi-cell panel, so as to realize the control of the light intensity of the passing light. Briefly described, the LCD multi-cell panel utilized in this scheme is as follows:
as shown in fig. 2, fig. 2 is a schematic diagram of an exemplary liquid crystal panel. The LCD panel takes TN type liquid crystal as an example, the TN type liquid crystal is connected in series along the long axis direction, and the long axes are arranged in parallel with each other. When contacting the cell surface, the liquid crystal molecules are aligned in the cell along the direction of the cell. When liquid crystal is contained between two groove-like surfaces and the directions of the grooves are perpendicular to each other, the arrangement of the liquid crystal molecules is: upper surface molecule: along the a direction; surface molecules: along the direction b; molecules intermediate to the upper and lower surfaces: creating a spinning effect. The liquid crystal molecules are rotated by 90 degrees between the two groove-like surfaces. The deflection effect diagram is shown in fig. 3, and fig. 3 is an exemplary liquid crystal molecule inversion effect diagram. The liquid crystal is uniformly distributed under the action of voltage, namely when voltage is applied between the upper surface and the lower surface, liquid crystal molecules are arranged along the direction of an electric field to form a vertical arrangement phenomenon. At this time, the incident light is not affected by the liquid crystal molecules and is emitted out of the lower surface linearly.
FIG. 4 is a schematic diagram of an exemplary liquid crystal polarization characteristic. The LCD panel has the characteristics of a polarizer, as shown in fig. 4 (top), the non-polarized light (general light) is filtered into polarized light, when the non-polarized light passes through the polarizer in the a direction, the light is filtered into linear polarized light parallel to the a direction, the linear polarized light continues to advance, and when the non-polarized light passes through the second polarizer, the light passes through; as shown in fig. 4 (bottom), the linearly polarized light continues to pass through the second sheet, where it is completely blocked. In the specific control process of light passing performance, when the upper polarizer and the lower polarizer are perpendicular to each other, namely, the angle is 90 degrees, if no voltage is applied, light can pass through, and when the voltage is applied, light can be correspondingly shielded. After voltage is applied to the LCD panel, electric field variation is generated by current passing through the transistor to cause liquid crystal molecules to deflect, so that the polarization of light is changed, and the passing light is shielded/passed through the arranged polaroid to realize different bright and dark states.
Fig. 4a is a schematic diagram of another exemplary liquid crystal panel. Fig. 4b is a schematic diagram of another exemplary liquid crystal panel. The biggest difference from the one shown in fig. 2 is that no polarizing plate is required, and the inner wall of the liquid crystal container is not provided with a groove-like surface. When no current is applied, as shown in fig. 4a, the liquid crystal molecules contained in the glass film are in a disordered arrangement state due to no traction of the inner wall groove-shaped surface, and light cannot penetrate through the glass film, so that the glass film is seen in a white non-transparent state. When the power is on, as shown in fig. 4b, the liquid crystal molecules inside the glass film are orderly arranged, and light can smoothly penetrate through the glass film, so that the glass film is seen to be transparent.
In this scheme, through LCD polycrystal unit board to the light intensity of passing through control, the illumination adjustment strategy that specific control mode was confirmed according to. Specifically, taking an example that the illumination adjustment strategy includes a backlight photographing strategy, a photographing target is firstly identified, and then a highlight area corresponding to the photographing target is determined, and then the light passing rate of the highlight area is reduced through the LCD multi-crystal unit plate. Fig. 5 is a schematic view of an LCD multi-cell panel according to the present invention, wherein each cell can perform individual light and dark transmittance control by a control signal, that is, the brightness of the high-brightness cell in the vicinity of the object to be photographed is reduced.
In this scheme, as shown in fig. 6 and 7, fig. 6 is a schematic diagram of a positional relationship among an LCD multi-cell plate, a camera lens and an image sensor provided in an embodiment of this scheme; fig. 7 is a schematic diagram of a positional relationship between another LCD multi-cell panel, a camera lens and an image sensor according to the embodiment of the present disclosure. As shown in fig. 6, the light sequentially passes through the lens and the LCD multi-chip panel to reach the image sensor; as shown in fig. 7, the light passes through the LCD multi-crystal panel and the lens in order to reach the image sensor. In one embodiment, the image area captured by the image sensor corresponds to the size of the LCD multi-die plate.
As shown in fig. 8, fig. 8 is a schematic diagram of light transmittance curves of an on state and an off state for different wavelengths according to the embodiment of the present disclosure. The abscissa is the wavelength of different light rays, and the ordinate is the corresponding light ray passing rate in the on state and the off state. By inquiring the curve, the light passing rate of more than 400nm under the on-state condition is good, namely visible light (400nm-700nm) and near infrared light (more than 700nm) can pass through; in the off state, the visible light passing rate is almost 0, and near infrared light with the wavelength larger than 800nm can normally pass through to realize the near infrared imaging function, so that the infrared-CUT optical spectrum switching device can be used as a static controllable device to replace the mechanical spectrum switching function of the IR-CUT.
According to the scheme, the image generation method is based on the LCD multi-crystal element plate, the thickness of the LCD multi-crystal element plate is very low, and other traditional motors and springs are not needed to control, wherein the LCD multi-crystal element plate is arranged between the lens of the camera and the image sensor or between the lens of the camera and the image sensor, the corresponding illumination adjustment strategy under the current image generation scene is determined, and the LCD multi-crystal element plate is controlled to control the intensity of the passing light according to the illumination adjustment strategy, so that the adjusted light is induced by the image sensor to generate the image. The scheme realizes dynamic adjustment of brightness of the shot image, expands the shooting function, can obtain the image with better effect, and is convenient to install.
In one embodiment, the LCD multi-die panel can be controlled to control the intensity of the light passing through according to the light passing rate and/or mask information manually set by a user.
In one embodiment, the mask information is an array containing information about the light transmittance of the wafer, including the start position, length, width, data size, and overall transmittance, and the light transmittance may be represented by 0.0-1.0 or 0-255. Illustratively, the mask information is converted into a gray scale map according to the scale of the generated image and is aligned with the generated image, and then the position, shape, size, light passing rate of each wafer, and other information of the mask can be determined through the array of the light passing rate information in the mask information.
Fig. 9 is a flowchart of another method for generating an image based on an LCD multi-cell panel according to an embodiment of the present invention, which provides a specific method for controlling the LCD multi-cell panel to control the intensity of light passing through according to the illumination adjustment strategy. As shown in fig. 9, the specific process is as follows:
step S201, received light passing rate control.
Step S202, determining the overall light intensity of the current shooting picture, and reducing the overall light passing rate through the LCD multi-crystal element plate to enable the adjusted light to pass through the image sensor to generate an image.
And aiming at the external instruction, when the determined light passing rate is received, determining the adjusting voltage of the corresponding wafer according to the light passing rate, and controlling the voltage of the wafer to be the corresponding adjusting voltage, thereby realizing the light passing rate of the external control camera. The design is further carried out, a visible light and near-infrared double-pass CUT-off filter is adopted, namely visible light with the wavelength of 400nm-700nm and near-infrared light with the wavelength of 800nm, 820nm, 850nm, 920nm and/or 940nm are allowed to pass through at the same time, when the light passing rate manually set by a user is 0, the passing rate of the visible light is 0%, and the near-infrared light passes through well, a near-infrared image is generated, so that the near-infrared imaging function is realized, and the mechanical spectrum switching function of replacing IR-CUT as a static controllable device can be realized.
Fig. 10 is a flowchart of another image generating method based on an LCD multi-cell panel according to an embodiment of the present invention, which provides a specific method for controlling the LCD multi-cell panel to control the intensity of light passing through according to the illumination adjustment policy. As shown in fig. 10, the specific process is as follows:
and S301, receiving mask information control.
Step S302, determining the light passing rate of each wafer of the LCD multi-wafer plate corresponding to the mask information, and enabling the adjusted light to pass through the image sensor to generate an image through the light passing rate of each wafer of the LCD multi-wafer plate.
When the determined mask information is received, the light passing rate of the LCD polycrystalline element plate corresponding to the crystal elements is determined according to the gray information of each pixel point in the mask information, the adjusting voltage of the corresponding crystal elements is determined according to the light passing rate of each crystal element, the voltage of the crystal elements is controlled to be the corresponding adjusting voltage, and therefore the light passing rate of the external control camera is achieved. The functions of controlling the whole illumination brightness, partially shielding and the like can be realized aiming at various illumination modes such as direct sunlight, a high beam, backlight and the like, so that the image generation device can adapt to various illumination environments.
