[0002] Currently, mobile phone cameras, for example, primarily consist of five components: a PCB substrate, a lens, a holder, a color filter, and a DPS. The lens itself contains multiple lenses, which offer benefits such as enhanced resolution and contrast, but also increase height. Although mobile phone cameras have become extremely miniaturized, they still face spatial conflicts between their height and, for example, the thinness of the phone.

[0245] Wherein, the filter further includes:
[0246] The corresponding shapes include at least one or more of rectangle, square, circle, ellipse and arc shape;
[0247] The corresponding dimensions include at least: not less than the diameter of the top lens of the camera; or not less than the inner diameter or outer diameter of the top port of the lens barrel corresponding to the top lens of the camera;
[0248] The corresponding thickness includes at least: 0.05-0.1mm and / or 0.1-1mm and / or 1-2mm;
[0249] Its top surface may or may not have an anti-reflective coating;
[0250] Its edges may or may not be provided with opaque edging;
[0251] If the filter includes the polarizer, the driving unit may or may not include a first driving member, and the first driving member is used to adjust the rotation angle of the polarizer after the polarizer enters the collection light path of the camera to achieve a desired polarization filtering effect and enable the camera to obtain a third image;
[0252] If the filter includes the gradient filter, the driving unit may or may not have a second driving member, and the second driving member is used to adjust the distance between the dividing line of the gradient filter and the optical axis corresponding to the collection light path after the gradient filter enters the collection light path of the camera, and / or adjust the rotation angle of the dividing line of the gradient filter, so as to achieve a desired gradient filtering effect and enable the camera to obtain a fourth image; and if the driving unit does not have the second driving member and the camera includes an optical image stabilization component, the positional relationship between the optical axis corresponding to the collection light path and the dividing line is adjusted by the optical image stabilization component;
[0253] If the filter includes the folding mirror, the driving unit may or may not include a third driving member, and the third driving member is used to adjust the height difference between the folding mirror and the lens on the top of the camera after the folding mirror enters the collection light path of the camera, so as to achieve a desired refracted light effect and enable the camera to obtain a fifth image;
[0254] If the optical filters include specific filters, and the specific filters include at least the polarizing filter, the red filter, the green filter, the blue filter, or the red enhancement filter, then obtaining and responding to a preset imaging parameter adjustment instruction based on the type of the specific filter entering the acquisition light path, the imaging parameter including the exposure level, so that the camera obtains a sixth image;
[0255] If the optical filter is constructed of a transparent substrate and a filter coating provided on at least one side of the transparent substrate, and if the filter coating is provided on both sides of the transparent substrate, the types of the filter coatings may be the same or different.
[0256] It should be noted that the shape or size of the filter only needs to ensure that it covers the top lens of the camera, and does not require precise positioning or focusing to meet low processing precision and positioning requirements. The smaller the diameter of the top lens (such as 2mm), or the smaller the diameter of the light-through hole or the dimming hole, the smaller the required size of the filter can be, thereby reducing the rated power of the driver, improving the response speed of the driver, reducing the volume of related components, reducing noise, and saving power. In some embodiments, the filter module is preferentially coupled to or only coupled to the top lens with the smallest diameter, or the light-through hole or the dimming hole with the smallest diameter, or the top lens with the smallest height difference between the top lens and the light-through hole. The camera corresponding to the smallest height difference can be a periscope camera.
[0257] The corresponding size of the filter can also be no less than the diameter of the light-through hole and / or the dimming hole. The thinner the filter, the less light loss it causes. The anti-reflective coating has the function of increasing light transmission, thereby reducing reflections and preventing them from reflecting back and forth between the top surface of the filter and the bottom surface of the protective cover, thereby causing light disturbance.
[0258] For example, the above:
[0259] A polarizing filter reduces light reflected from surfaces. It can make skies appear bluer and flowers appear more vibrant. It can also reduce reflections in water and eliminate haze in low-angle shots. When loading, increase the exposure by two stops. When using the polarizing filter, try to keep the optical axis of the filter at a 90° angle to the sunlight. This filter should not be used with a wide-angle camera, as this will result in uneven brightness in the image.
[0260] UV filter, also known as ultraviolet filter, can basically eliminate the impact of ultraviolet rays and stray light on photosensitivity, and play a protective role on the lens.
[0261] Skylight mirror, which absorbs ultraviolet rays and is suitable for all weather conditions, reduces the blue cast in shadows.
[0262] A red filter absorbs blue light, creating a romantic sky effect or a moonlit night effect during daytime photography. It also absorbs ultraviolet rays. When using this filter (i.e., loading it into the camera's acquisition light path), you'll generally need to increase the exposure by three stops.
[0263] Orange filter: This filter absorbs blue and green light and passes yellow, orange and red light, which can enhance the contrast of the scenery.
[0264] Yellow filter, can accurately correct the tone of panchromatic film, to obtain greater contrast between blue sky or trees and white clouds.
[0265] A green filter allows yellow and green light to pass through, while absorbing red, blue, and violet light. It's often used to darken skies and enhance skin tones. After loading the camera's acquisition light path, increase the exposure by approximately three stops.
[0266] The blue filter can pass cyan, blue, and violet light, while absorbing red, orange, and yellow. It is necessary to increase the exposure by about 2 levels.
[0267] A neutral density filter, also known as an ND filter, is a type of filter that absorbs light within the visible light range, blocking and modulating brightness without altering color. It's used to create silky patterns in flowing water. When shooting in strong light with a wide aperture to achieve a shallow depth of field, shutter speeds often exceed their limits, resulting in overexposed photos. Using a neutral density filter can reduce the amount of light entering.
[0268] Raden filters include Raden 80, a color temperature conversion filter; Raden 81, a warm light balancing filter; Raden 82, a color balancing filter; and Raden 85, a color temperature conversion filter.
[0269] Fluorescent filters are special color compensation filters that can correct color casts and restore true colors to the image.
[0270] Neutral night view filter, a gray filter type, has a strong light blocking effect. It can capture excellent night scene effects in daylight.
[0271] A red intensifier filter, made from imported optical materials infused with expensive rare earth elements, significantly enhances the color saturation of red, light red, and brownish-red objects in a scene, making them more vivid, vibrant, and intense. For example, it can make autumn maple leaves appear crimson, strawberries and tomatoes appear more attractive, sunsets feel richer, and weddings or Christmas scenes more festive. When used, increase exposure by 1 / 2-1 stop. When used in conjunction with a polarizing filter, this filter can make blue skies appear richer and more beautiful.
[0272] Infrared filters are used to capture infrared photos and dynamic scenes. Daylight contains a large amount of infrared rays, but visible light is even stronger, so an infrared filter is needed to filter out visible light to achieve a pure infrared effect.
[0273] Infrared cut filters, also known as infrared filters or heat-absorbing filters, are filters used to filter infrared wavelengths. They are used to block unnecessary heat from burning the lens and prevent infrared rays from causing image distortion.
[0274] Gradient filters can be divided into gradient color filters and gradient diffusers. Their gradient can be further categorized as soft or hard. Soft gradients have a wider transition range, while hard gradients have a narrower transition range. Gradient filters are ideal for capturing scenes with high light contrast, especially sunrises and sunsets, effectively balancing the light ratio between ground and sky. Using a gradient filter can achieve a more natural and realistic look, or reduce the complexity of computational photography and its real-time rendering capabilities.
[0275] Soft focus filters, also known as soft focus filters, come in 1#, 2#, and 3# sizes. Using these filters creates a soft and clear effect. For portraits, they can soften wrinkles, spots, and pores on the skin, creating a delicate, plump, and youthful effect.
[0276] A fog filter is a common filter used in nature photography, as well as advertising and portrait photography, to create a foggy effect. Exposure affects the intensity of the fog.
[0277] The Crescent Soft Hazy Mirror belongs to the category of hazy mirrors and can be used to create special effects in wedding photography. The mirror is clear on the top and hazy on the bottom. The crescent shape can give people a dreamlike feeling and is full of romance.
[0278] A speeding camera is a special-effect camera with one half transparent and the other half made of a cylindrical lens. It makes the front of the subject's image clear, while the rear portion of the image appears to be a shadow, creating the illusion of rapid motion.
[0279] A reflection mirror is a rectangular mirror with positive reflection (vacuum silver-plated surface). It can capture land scenery, buildings, people, etc. without surrounding water, as if they were taken at the edge of a lake or river, with clear reflections.
[0280] Starlight Mirrors, centered around a luminous point, feature a series of regularly etched parallel lines, ranging from 2 to 4, 6 to 8 or 16 lines, on the surface of colorless optical glass. The diffraction of light creates a radiant effect. For example, when photographing a stage or night scene, the lights within the frame can be made to appear to shimmer.
[0281] A magic filter, also known as a cyclone filter, focuses light in the center and scatters it in a spiral pattern, creating a sense of motion. When using it, use a wide-angle lens or a small aperture, preferably a small aperture.
[0282] Hollow mirrors have a central portion that retains its original glass structure, while the surrounding glass is processed using a special process to create various effects. The main effect of this mirror is to highlight the theme and create an atmosphere that enhances the central part.
[0283] A dream lens creates a dreamlike effect by focusing on the center of the image while blurring and halos the surrounding scenery. This lens is often used for weddings, celebrity portraits, and other artistic photography. The effect is most pronounced against dark backgrounds and with a long focal length lens.
[0284] A close-up lens, when used, allows the lens to focus on objects much closer than usual, creating a close-up effect. Available in four levels: +1, +2, +3, and +4, it's recommended to use a small aperture when shooting.
[0285] Prisms can have two, three, four, or five shadows. When shooting, a small aperture minimizes image overlap; a large aperture results in more overlap. Close shooting distances increase image overlap, while long distances minimize overlap.
[0286] The multi-row lens is a prism-type lens. Its usage is the same as the multi-prism lens, except that the lenses are arranged in the same direction. This lens can create special interest and effects and is also suitable for advertising photography.
[0287] A rainbow mirror, also known as a rainbow after rain mirror, is used to artificially simulate a rainbow effect in any season and weather conditions. When shooting, it's best to use backlighting, and be aware of how changes in focal length and aperture affect the clarity of the rainbow.
[0288] MC-UV filter, also known as multi-layer coated UV filter or multi-layer coated anti-UV filter, can protect the lens, filter ultraviolet rays, enhance contrast and increase color saturation.
[0289] The semi-transparent mirror is used to reduce the intensity of natural light, for example, when shooting scenery in strong light or facing the sun.
[0290] The light-proof mirror is used to cover the camera, especially when the camera is not working, it can be used to remind the user that the camera is currently in a non-working state, and can also be used to prevent hackers from remotely controlling the camera to take secret photos.
[0291] The aperture lens is composed of a transparent disk or circular or rectangular hole with a certain diameter in the center. It is used to obtain apertures of different shapes and / or sizes. It can be used in combination with other filters.
[0292] The folding mirror is a lens that refracts light to achieve a zoom effect.
[0293] The gradient mirror is preferably shaped like a square, so that the gradient mirror is stably constrained to the guide rail when driven, and the gradient boundary line of the gradient mirror is kept in a stable direction when the distance between the gradient boundary line and the optical axis of the collection light path is adjusted.
[0294] The camera group may further include a flash module and / or a photosensitive device. It is necessary to consider the spatial relationship or avoidance relationship or mutual light interference between the camera and the flash module and / or the photosensitive device.
[0295] Second aspect embodiment
[0296] The protective cover described in the second aspect of the present invention can simplify and compact the structure of the camera system, reducing its overall thickness. It also has the advantage of allowing the filter module and the light isolation module to be invisible beneath the protective cover.
