When shooting is carried out at low light source intensity (namely at a dark light position), because the brightness at the dark light position is low, the gain and the shutter value can easily reach the maximum, namely the light inlet quantity reaches the maximum, because the aperture is fixed, the light inlet quantity can not be increased any more, the signal-to-noise ratio of signals is low, and after the signals are amplified by a large multiple of gain, noise points are easily generated on images. On the contrary, in a high light source intensity (i.e., a strong light area), since the amount of incident light is very large, the amount of incident light cannot be effectively reduced by the shutter, so that the generated image is likely to generate flare light (a phenomenon that an image is whitened and halo is formed due to the strong light), and the contrast is reduced, so that the image looks like being covered with a layer of gray.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first" and "second" in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
The embodiment of the invention provides a photographing processing method and terminal equipment, which can reduce noise and/or glare in an image and improve the imaging quality of the image in the photographing process.
In the embodiment of the present invention, the terminal device includes a terminal device running an Android operating system, an iOS operating system, a Windows operating system, or other operating systems, such as a mobile phone, a mobile computer, a tablet computer, a desktop computer, a Personal Digital Assistant (PDA), an intelligent watch, an intelligent bracelet, and the like. The terminal equipment comprises a camera and an image sensor, and a filter is covered on the surface layer of the image sensor.
Referring to fig. 1, fig. 1 is a schematic flow chart of a photographing processing method according to an embodiment of the present invention. The method shown in fig. 1 is applied to a terminal device having a camera, where the camera includes an image sensor, the image sensor includes a photosensitive pixel array and an optical filter disposed on the photosensitive pixel array, and the photographing processing method shown in fig. 1 may include the following steps:
101: acquiring a preview image acquired by a camera, and detecting whether noise or glare exists in the preview image;
in the embodiment of the invention, a user can input a camera starting instruction through input equipment such as a touch screen or a physical key in the terminal equipment, control the camera of the terminal equipment to be in a preview photographing mode and acquire a preview image acquired by the camera.
The camera may be a built-in camera of the terminal device, such as a front camera and a rear camera, or an external camera of the terminal device, such as a rotary camera.
Based on the introduction of the background art, when the light source intensity is low (i.e. in the dark), the brightness is low in the dark, the gain and the shutter value are easy to reach the maximum, i.e. the light input amount reaches the maximum, the light input amount cannot be increased any more due to the fixed aperture, the signal-to-noise ratio of the signal is low, and after the signal is amplified by the gain of a large multiple, the image is easy to generate noise. On the contrary, in a high light source intensity (i.e., a strong light area), since the amount of incident light is very large, the amount of incident light cannot be effectively reduced by the shutter, so that the generated image is likely to generate flare light (a phenomenon that an image is whitened and halo is formed due to the strong light), and the contrast is reduced, so that the image looks like being covered with a layer of gray. Therefore, before taking a picture, it may be detected whether noise or glare is present in the preview image.
In this embodiment of the present invention, the image sensor may be a Charge Coupled Device (CCD) image sensor, a Complementary Metal Oxide Semiconductor (CMOS) sensor, or another sensor capable of implementing an image acquisition function, which is not limited in the embodiments of the present invention.
As an alternative embodiment, detecting whether noise exists in the preview image may be implemented as follows: noise points in an image may also be referred to as Pixel Response Non-Uniformity (PRNU) points, which refer to points with larger grayscale value jump with surrounding neighborhood points, and based on the above theory, an image may be grayed first, then the image is divided into a plurality of regions, the grayscale value of each Pixel point in each region is determined, and then the Pixel point with the grayscale value of an extreme point in the region is determined, and then the Pixel point with the grayscale value of the extreme point is the noise point in the region. The extreme point may be a maximum point or a minimum point.
It should be noted that the above example is only an alternative implementation for determining noise, and is not to be construed as limiting the embodiments of the present invention.
As an alternative embodiment, detecting whether glare exists in the preview image may be performed in the following manner: because the glare is a point with a relatively large brightness value in the image, it may be determined whether there is a pixel point with a brightness value greater than a preset brightness value in the preview image, where the preset brightness value may be set by a system or a user according to a brightness value corresponding to the glare, for example, may be 50lux (lux), and then the pixel point with a brightness value greater than the preset brightness value in the preview image is determined as the glare. Since glare generally occurs around strong light (for example, indoor lighting, sunlight, and the like), and the surrounding of the strong light is a place with the highest brightness value in the preview image, the position of the strong light can be determined by detecting the brightness value of each pixel point in the preview image, and the position of the glare in the preview image can be determined.
It should be noted that the above example is only an alternative implementation for determining glare, and does not limit the embodiments of the present invention.
102: if the preview image has noise or glare, judging whether the noise intensity in the preview image exceeds a preset noise intensity threshold value and/or whether the glare intensity in the preview image exceeds a preset glare intensity threshold value;
if there is noise or glare in the preview image, but the noise intensity or glare intensity is relatively low, and the overall quality of the image is not affected, then no processing may be performed, and if the noise intensity exceeds a preset noise intensity threshold and/or the glare intensity exceeds a preset glare intensity threshold, step 103 needs to be performed to adjust the thickness of the optical filter, and change the amount of light entering the image sensor.
The noise intensity is a quantitative calculation of the noise and is used for describing the roughness of a rough part (namely the noise) in the image, and the noise intensity can be represented by calculating the deviation degree of the gray value at the noise and the mean value of the gray values of all pixel points in the neighborhood of the noise; the glare intensity may be determined by the degree of deviation between the brightness value at the glare and a preset brightness threshold; the preset noise intensity threshold or the preset glare intensity threshold may be determined by a user according to a test, so as to satisfy a good image quality, which is not limited uniquely in the embodiments of the present invention.
103: if the intensity of the noise in the preview image exceeds a preset noise intensity threshold and/or the intensity of the flare light in the preview image exceeds a preset flare intensity threshold, adjusting the thickness of an optical filter corresponding to an imaging pixel generating the noise or the flare light so as to change the light entering into an image sensor;
in the embodiment of the present invention, if the intensity of noise in the preview image exceeds a preset noise intensity threshold and/or the intensity of flare in the preview image exceeds a preset flare intensity threshold, the thickness of the optical filter corresponding to the imaging pixel generating the noise or flare is adjusted to change the amount of light entering the image sensor.
The image sensor is sequentially provided with a lens layer, a filter layer and a photosensitive array layer, lenses in the lens layer and color filters in the filter layer are arranged according to an array of diodes in the photosensitive array layer, namely, a color filter and a micro lens are sequentially attached to each photosensitive diode, namely, one pixel sequentially corresponds to one color filter and one micro lens. The lens layer is used for focusing incident light rays into the filter layer, and the filter layer is used for filtering out colors, so that the light sensed by each diode is monochromatic. As shown in fig. 2, a schematic diagram of a light path of the light passing through the optical filter is shown, and as can be seen from fig. 2, when the light passes through the optical filter, a part of light is reflected, and a part of light enters the photosensitive array layer after being refracted. The light ray a is reflected by the upper surface and the lower surface of the optical filter to form two parallel reflected lights a 'and b', because the two light beams a 'and b' are formed by dividing the same light ray a according to the intensity (split amplitude method), the two light beams are two coherent lights, the optical path difference between the two light beams is related to the thickness of the optical filter, when the optical path difference between the two light beams a 'and b' is even times of half wavelength, the phases of the reflected lights are the same, interference is added, the energy of the reflected light is increased, the energy of the transmitted light entering the photosensitive array layer is reduced, when the optical path difference between the two light beams a 'and b' is odd times of half wavelength, the phases of the reflected light are opposite, interference is subtracted, the energy of the reflected light is reduced, and the energy of the transmitted light entering the photosensitive array layer is increased. Therefore, according to the above principle, the amount of light transmitted into the photosensitive array layer can be increased or decreased by changing the thickness of the filter and changing the optical path difference. For example, if the brightness value of a noise point in the preview image is detected to be large in a low-light environment, the thickness of a color filter on an imaging pixel point corresponding to the noise point can be changed, so that the optical path difference is odd times of half wavelength, thereby increasing the light incoming amount of the image sensor, improving the signal-to-noise ratio and reducing the noise point; if the fact that the glare brightness value is large in the preview image is detected in the environment with strong light rays, the thickness of the color filter on the imaging pixel point corresponding to the glare point can be changed, the optical path difference is even times of half-wavelength, the light incoming quantity of the image sensor can be reduced, the contrast is improved, and the glare phenomenon is reduced.
As an alternative embodiment, the thickness of the filter may be changed using a temperature control device, or a plurality of filters may be placed on the photodiode, and the thickness of the filter may be changed by increasing or decreasing the number of filters. It should be noted that the optical path difference is not only related to the thickness of the optical filter, but also related to the refractive index of the optical filter, and the refractive index of the optical filter can change with the change of temperature, and in general, the refractive index will increase with the increase of temperature, so the temperature can be changed by the temperature control device, thereby changing the refractive index, and further changing the optical path difference between the two beams of light a 'and b' reflected by the optical filter.
104: and controlling the camera to capture the scene and generate the photo.
In the embodiment of the present invention, after the amount of light entering the image sensor is adjusted in step 103, the terminal device may control the camera to capture a scene, the captured scene is transmitted to the lens and focused on the image sensor through the lens, the image sensor accumulates corresponding charges according to the intensity of light, and generates an electrical signal for identifying a frame through periodic discharge, the electrical signal is amplified by the amplifying circuit and is subjected to AGC automatic gain control, and then the electrical signal is transmitted to the image digital signal processor through analog-to-digital conversion for processing, and finally the image can be viewed through the display screen.
In the embodiment of the invention, whether noise or glare exists in a preview image acquired by a camera is detected, whether the noise intensity exceeds a preset noise intensity threshold and/or whether the glare intensity in the preview image exceeds a preset glare intensity threshold is judged when the noise or glare exists, and the thickness of an optical filter corresponding to an imaging pixel generating the noise or glare is adjusted when the noise intensity exceeds the preset noise intensity threshold and/or the glare intensity exceeds the preset glare intensity threshold, so as to change the light entering into an image sensor; and finally, controlling the camera to capture the scenery and generating a photo. By implementing the embodiment of the invention, the noise and/or glare phenomena in the image can be reduced, and the imaging quality of the image in the photographing process is improved.

in the embodiment of the invention, if the noise intensity in the preview image is detected to exceed a preset noise intensity threshold and/or the glare intensity exceeds a preset glare intensity threshold, a first position of the noise or the glare in the preview image is determined, and then a second position of an imaging pixel point generating the noise or the glare in a photosensitive pixel array is determined according to the first position, namely which photosensitive diode in a photosensitive array layer of an image sensor generates is determined, so that the thickness of a color filter on the surface layer of the photosensitive diode is changed, and the light entering amount of the photosensitive diode is adjusted.
The thickness of the optical filter corresponding to the imaging pixel point generating the noise or the glare is adjusted to change the amount of light entering the image sensor, which can be performed for the noise or the glare, and the following method can be adopted:
