Image capture device

Abstract

This application relates to an image capture device. The image capture device includes a housing, a strobe sensor, and a light guide assembly. The strobe sensor is disposed within the housing. The light guide assembly is disposed within the housing and has a first surface treatment layer located on the side of the light guide assembly away from the strobe sensor. According to an embodiment of the image capture device of this application, the first surface treatment layer causes incident light to undergo diffuse reflection on the outer surface of the light guide assembly. The first surface treatment layer disperses concentrated reflected light into uniform scattered light, preventing strong reflected light from directly entering the strobe sensor. Simultaneously, the first surface treatment layer can reduce interference from ambient light, such as ambient light sources and specular reflection from objects, further reducing the impact of stray light on signal processing. Through the diffuse reflection and stray light scattering effect of the first surface treatment layer, the uniformity of the light path is improved, reducing imaging stripe problems caused by stray light interference.

[0030] Currently, with the improvement of living standards, people's demand for image capture devices such as cameras, video recorders, and action cameras is becoming increasingly widespread. The application of stroboscopic sensors in the field of image capture equipment is becoming more and more extensive.

[0031] Traditional stroboscopic sensors with light guides suffer from problems such as high fragility, high processing costs, poor batch consistency, limited surface treatment processes, severe stray light interference, and significant fluctuations in stroboscopic signals. The etching process for glass light guides leads to unstable light transmittance, and surface treatments cannot enhance the product's premium appearance.

[0032] Based on the above considerations, in order to solve the above problems, this application designs an image capture device. By setting a first surface treatment layer 311 on the light guide component 300, the light transmission is more uniform, stray light interference is reduced, and the appearance texture and structural stability are improved.

[0033] The "image capture device" in this application embodiment can be a camera, such as a digital camera: including DSLR cameras, mirrorless cameras, and portable digital cameras; it can also be a film camera: a traditional camera that uses film to record images; it can also be a personal digital assistant (PDA), a smartphone: modern smartphones are usually equipped with high-quality front and rear cameras, capable of taking high-resolution photos and videos; it can also be a camcorder, such as a portable camcorder: such as a handheld video recorder, used for shooting videos, or a professional camcorder: a specific device used for film and television production; it can also be a webcam: a camera device used for video conferencing or live online streaming, usually mounted on a computer or monitor; it can also be an action camera or sports camera: more durable and compact than traditional camcorders, suitable for extreme sports or outdoor activities; and it can also be a drone: a drone equipped with camera equipment that can capture images and videos from the air.

[0034] See Figure 1 , Figure 2 and Figure 3 At least one embodiment of this application provides an image capture device, which includes a housing 100, a strobe sensor 200, and a light guide assembly 300. The strobe sensor 200 is disposed within the housing 100. The light guide assembly 300 is disposed within the housing 100 and has a first surface treatment layer 311, which is located on the side of the light guide assembly 300 away from the strobe sensor 200.

[0035] According to the image capture device of this application embodiment, the first surface treatment layer 311 causes incident light to undergo diffuse reflection on the outer surface of the light guide component 300. The outer surface of the light guide component 300 is the surface of the light guide component 300 facing the outside of the image capture device. The first surface treatment layer 311 disperses the concentrated reflected light into uniform scattered light, preventing strong reflected light from directly entering the flicker sensor 200. Simultaneously, the first surface treatment layer 311 can reduce interference from ambient light, such as ambient light sources and specular reflections from objects, further reducing the impact of stray light on signal processing. Through the diffuse reflection and stray light scattering effect of the first surface treatment layer 311, the uniformity of the light path is improved, reducing imaging stripe problems caused by stray light interference.

[0036] In some embodiments, the light guide component 300 is formed in one step using a plastic injection molding process, and the first surface treatment layer 311 can be directly etched through the mold without additional surface treatment. This reduces processing steps, avoids the damage risks in traditional glass processing, and improves production efficiency. Coordinated control of the injection molding process and the mold enables uniformity of the composite texture.

[0037] The injection-molded light guide component 300 has low hardness but high toughness. When subjected to external force, it often develops shallow surface wear or minor scratches, and the surface texture of the first surface treatment layer 311 can conceal these scratches, making them difficult to detect with the naked eye. Even with minor scratches, the diffuse reflection characteristics of the plastic light guide component 300 can still maintain the uniformity of light propagation, avoiding signal fluctuations caused by specular reflection defects after glass scratches. The first surface treatment layer 311 achieves light diffusion through surface texture, and combined with the precise texture formed by the mold, ensures a consistent light path, reducing flicker signal fluctuations caused by uneven reflection from the smooth surface of traditional glass.

[0038] The plastic light guide component 300 has high toughness, improved impact resistance, and is less prone to breakage, thus extending the equipment's lifespan. At the same time, the light guide component 300, made using plastic injection molding, significantly reduces weight, meeting the equipment's portability requirements and complying with lightweight design principles.

[0039] See Figure 3 In some embodiments, the first surface treatment layer 311 includes a frosted structure disposed on the surface of the light guide assembly 300 away from the flicker sensor 200. The frosted structure achieves a matte texture effect. The frosted surface itself has an irregular microscopic uneven structure; when the surface is scratched, the newly generated scratches blend with the original frosted texture, making them visually difficult to distinguish. Simultaneously, the tiny protrusions and depressions of the frosted structure can disperse the stress of external impacts, reducing the risk of deep scratches caused by concentrated localized force. Even in the event of minor scratches, the diffuse reflection characteristics of the frosted structure can still maintain the uniformity of light scattering, avoiding inconsistencies in light reflection caused by scratches.

[0040] In some embodiments, the surface roughness of the side of the first surface treatment layer 311 away from the strobe sensor 200 is 0.8 μm-1.6 μm. The roughness of 0.8 μm-1.6 μm enables the first surface treatment layer 311 to effectively scatter stray light through diffuse reflection while ensuring the transmission efficiency of light within the light guide assembly 300.

[0041] In some embodiments, the light guide assembly 300 is further provided with a second surface treatment layer 321, which is located on the side of the light guide assembly 300 near the flicker sensor 200. The second surface treatment layer 321 acts on the path of light emitted from the light guide assembly 300 to the sensor. In the prior art, the inner side of the glass light guide column is mostly a smooth surface, and when light is incident, it is prone to specular reflection or total internal reflection due to angular deviation, which causes the light to fail to accurately enter the light receiving end 210 of the sensor and easily generates stray light interference. The second surface treatment layer 321 modulates the light a second time to ensure that the light path entering the flicker sensor 200 is uniform and stable, reducing reflection loss and interference.

[0042] See Figure 4 In some embodiments, the second surface treatment layer 321 includes a CD texture structure 3211, which is disposed on the surface of the light guide assembly 300 near the flicker sensor 200. CD texture is a surface treatment process, also known as Code Division. It involves removing material from a metal surface using a precision CD texturer, or using precision machining, chemical etching, or other methods to create tiny grooves or protrusions on the metal surface, thereby forming a texture effect similar to a CD disc. CD textures are precisely molded, resulting in high and uniform texture density, presenting a high-quality concentric circle decorative effect, enhancing the premium look of the device, and are suitable for specific consumer electronics scenarios. Even with minor scratches, the regular geometric shape of the CD texture maintains the regularity of the light path, avoiding light disturbance caused by scratches disrupting the texture's regularity.

[0043] See Figure 4 and Figure 5 In some embodiments, the CD-pattern structure 3211 includes annular protrusions 32111 and annular grooves 32112. The annular protrusions 32111 have an axis, and the axes of multiple annular protrusions 32111 coincide. The diameter of the annular protrusions 32111 gradually increases along the radial direction of the annular protrusions 32111. Every two adjacent annular protrusions 32111 and the surface of the light guide assembly 300 form an annular groove 32112. Through the above arrangement, the CD-pattern structure 3211 refracts divergent light into beams parallel to or converging towards the axis, guiding the light accurately into the light-receiving path of the flicker sensor 200. The light-receiving path of the flicker sensor 200 is along... Figure 3 The X-direction setting in the settings.

[0044] See Figure 4 and Figure 5 In some embodiments, in the CD pattern structure 3211, the spacing D between adjacent annular protrusions 32111 is 0.1mm-0.3mm. The radial width W of the annular protrusions 32111 is 50μm-200μm. The depth H of the annular grooves 32112 is 5μm-50μm.

[0045] In the CD pattern structure 3211, the spacing D between adjacent annular protrusions 32111 includes, but is not limited to, 0.1mm, 0.12mm, 0.14mm, 0.15mm, 0.16mm, 0.18mm, 0.2mm, 0.22mm, 0.24mm, 0.25mm, 0.26mm, 0.28mm or 0.3mm.

[0046] The radial width W of the annular protrusion 32111 includes, but is not limited to, 50μm, 60μm, 70μm, 80μm, 90μm, 100μm, 110μm, 120μm, 130μm, 140μm, 150μm, 160μm, 170μm, 180μm, 190μm or 200μm.

[0047] The depth H of the annular groove 32112 includes, but is not limited to, 5μm, 10μm, 15μm, 20μm, 25μm, 30μm, 35μm, 40μm, 45μm or 50μm.

[0048] Specifically, the spacing D between adjacent annular protrusions 32111 is not less than 0.1 mm to avoid interference stray light caused by excessively dense refraction of light. The spacing D between adjacent annular protrusions 32111 is not greater than 0.3 mm to prevent insufficient light path control due to excessive spacing, causing the divergence angle to exceed the receiving range of the strobe sensor 20°. The radial width W of the annular protrusion 32111 is not less than 50 μm to ensure the mechanical strength of the protrusion structure and prevent mold chipping or texture defects during injection molding due to excessive narrowness. The radial width W of the annular protrusion 32111 is not greater than 200 μm to limit the light refraction range of a single protrusion.

[0049] The image capture device in this embodiment achieves scratch resistance through the frosted structure of the first surface treatment layer 311 and the CD texture structure 3211 of the second surface treatment layer 321 on both sides of the light guide component 300. The scratches are not easily visible to the naked eye. The surface hardness of the plastic-molded light guide component 300 is lower than that of the glass light guide column in the prior art. When the light guide component 300 is scratched, the inconsistency will be reduced, avoiding multiple reflections of light.

[0050] It is understood that the first surface treatment layer 311 and the second surface treatment layer 321 in the embodiments of this application are not limited to being manufactured by injection molding. They can also be manufactured by various processes such as spraying, coating, and laser engraving to adapt to different materials and optical requirements, and flexibly realize surface structures such as frosted structure, CD texture structure 3211, grating or surface coating to improve the light scattering and refraction effect.

[0051] See Figure 3 In some embodiments, the flicker sensor 200 has a light-receiving path. The light-receiving path of the flicker sensor 200 is along... Figure 3 The X-direction setting is specified. A first through-hole 110 is provided on the housing 100, and the light guide assembly 300 covers the first through-hole 110, with the light receiving path passing through the first through-hole 110. The light receiving path refers to the effective transmission channel through which light enters the strobe sensor 200 from the outside, including the path of light passing through the light guide assembly 300 and the through-hole of the housing 100. The light guide assembly 300 completely covers the first through-hole 110, forming an optical seal with the first through-hole 110 to prevent light leakage at the edges.

[0052] In some embodiments, the image capture device further includes a light-averaging component disposed between the strobe sensor 200 and the light guide component 300. The light-averaging component is also positioned on the light-receiving path of the strobe sensor 200, performing light-averaging processing on the light passing through the light guide component 300 to make the light received by the strobe sensor 200 more stable. Furthermore, the light-averaging component has a certain effect on concealing imperfections.

[0053] In some embodiments, the light homogenizing component includes a light homogenizing sheet group 400, which includes at least one light homogenizing sheet 410. The light homogenizing sheet 410 has a transmittance of 70%-90%. The light homogenizing sheet 410 makes the light more uniform. Specifically, the light homogenizing sheet 410 has a transmittance of not less than 70% to avoid excessive absorption or scattering of light by the light homogenizing sheet 410, which would result in a weak light signal entering the flicker sensor 200. The light homogenizing sheet 410 has a transmittance of not more than 90% to avoid losing its stray light filtering function due to excessively high transmittance. If the transmittance is higher than 90%, the light homogenizing sheet 410 is close to transparent, making it difficult to suppress stray light such as ambient light and internal reflected light through scattering or absorption, and thus failing to achieve a light homogenizing effect.

[0054] By setting the above, the effectiveness of optical control of the light homogenizer 410 is ensured by limiting the light transmittance range, providing a uniform and stable incident light signal for the strobe sensor 200.

[0055] Understandably, when the light-diffusing filter group 400 contains only one light-diffusing filter 410, a light-diffusing filter 410 with a transmittance in the range of 70%-90% can be directly selected.

[0056] See Figure 6In some embodiments, when multiple light-diffusing sheets 410 are provided, the multiple light-diffusing sheets 410 are stacked sequentially along the light-receiving path, and the light transmittance of the light-diffusing sheets 410 increases sequentially along the direction close to the strobe sensor 200.

[0057] With the above configuration, the outer light-diffusing sheet 410 near the light guide assembly 300 has a lower transmittance, such as 70%; while the inner light-diffusing sheet 410 near the stroboscopic sensor 200 has a higher transmittance, such as 90%. The outer light-diffusing sheet 410 near the light guide assembly 300 intercepts strong stray light and attenuates its energy; the inner light-diffusing sheet 410 near the stroboscopic sensor 200 allows effective light signals filtered by the outer light-diffusing sheet 410 to pass through, reducing excessive attenuation of the light intensity received by the sensor.

[0058] In some embodiments, the transmittance gradient difference between adjacent light-diffusing sheets 410 is 15%-30%. This transmittance difference refers to the difference in transmittance between two adjacent light-diffusing sheets 410. For example, the outer light-diffusing sheet 410 has a transmittance of 70%, while the adjacent inner light-diffusing sheet 410 has a transmittance of 85%, resulting in a difference of 15%. This gradient difference controls the attenuation of light passing through adjacent light-diffusing sheets 410. This configuration reduces the fluctuation amplitude of the stroboscopic signal by 40%. Reduced fluctuation leads to a more stable light signal received by the stroboscopic sensor 200, decreasing misjudgments caused by signal abrupt changes and improving the stability, accuracy, and reliability of the device under varying lighting conditions.

[0059] See Figure 3 In some embodiments, a first mounting plate 500 and a second mounting plate 600 are disposed within the housing 100, and the flicker sensor 200 is disposed on the first mounting plate 500. The second mounting plate 600 is disposed on the side of the first mounting plate 500 near the flicker sensor 200, and a second through hole 611 is formed on the second mounting plate 600. The light guide assembly 300 is mounted on the second mounting plate 600 and covers the second through hole 611. The light-receiving path of the flicker sensor 200 passes through the second through hole 611.

[0060] With the above configuration, the first mounting plate 500 is fixed inside the housing 100 for mounting the flicker sensor 200, providing an mounting interface for the flicker sensor 200. The second mounting plate 600 is also fixed inside the housing 100 for mounting the light guide assembly 300. The diameter of the second through hole 611 is smaller than the light-transmitting area of ​​the light guide assembly 300, allowing the light guide assembly 300 to completely cover the second through hole 611, preventing light leakage. Furthermore, the first mounting plate 500 and the second mounting plate 600, acting as dual mounting plates, isolate reflections from other components inside the housing 100, preventing stray light and reflections from entering the light-receiving path.

[0061] See Figure 3In some embodiments, the strobe sensor 200 is provided with a light-receiving end 210, which is used to receive light incident along the light-receiving path. The light-receiving end 210 extends into the second through hole 611. The axis of the second through hole 611 coincides with the axis of the light-receiving end 210 and the first through hole 110 of the strobe sensor 200, ensuring that light enters the strobe sensor 200 along the light-receiving path and avoiding light intensity attenuation due to misalignment. The light-receiving end 210 extends directly into the second through hole 611, shortening the transmission distance of light from the light guide assembly 300 to the light-receiving end 210.

[0062] See Figure 3 In some embodiments, a first gap is provided between the outer wall of the light-receiving end 210 and the inner wall of the second through hole 611. The first gap can be understood as a radial gap between the outer wall of the light-receiving end 210 of the stroboscopic sensor 200 and the inner wall of the second through hole 611 of the second mounting plate 600, typically a uniformly distributed annular shape. This first gap serves two purposes: firstly, it facilitates the elimination of radial installation errors; secondly, it prevents interference or friction between the inner wall of the second through hole 611 and the outer wall of the light-receiving end 210 of the stroboscopic sensor 200, and avoids contact between the inner wall of the second through hole 611 and the outer wall of the light-receiving end 210 causing the photosensitive surface of the light-receiving end 210 to tilt, thus ensuring the stability of light incidence.

[0063] See Figure 3 In some embodiments, a second gap is provided between the light-receiving end 210 and the light guide assembly 300 along the light-receiving path. The second gap can be understood as the axial air gap between the light-receiving end 210 of the flicker sensor 200 and the light guide assembly 300 along the light-receiving path, i.e., the vertical distance between them on the light-receiving path. The second gap serves two purposes: firstly, it helps to eliminate axial installation errors; secondly, it prevents direct contact and friction between the light-receiving end 210 and the light guide assembly 300, avoiding scratches on the surface of both the light-receiving end 210 and the light guide assembly 300.

[0064] Specifically, the second gap can be set to 0.5mm-1.2mm. The second gap includes, but is not limited to, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, or 1.2mm. This setting ensures the effectiveness of the second gap while avoiding excessive light energy loss due to an excessively large gap.

[0065] It is understandable that the first and second gaps play a role in high-temperature expansion scenarios. When the operating temperature of the image capture device in this embodiment increases, such as during long-term continuous shooting and / or when the ambient temperature is also high, the light-receiving end 210 of the strobe sensor 200 and the light guide assembly 300 may expand radially or axially due to the different coefficients of thermal expansion caused by different materials. The first gap can accommodate the radial expansion difference between the housing 100 and the light-receiving end 210, and the second gap can accommodate the axial expansion difference between the housing 100 and the light-receiving end 210, avoiding compression and breakage caused by interference expansion, and ensuring the stability and accuracy of the incident angle of light.

[0066] In addition, the first gap and the second gap form a heat dissipation channel, which facilitates the heat dissipation generated by the strobe sensor 200, thereby achieving a heat dissipation effect and ensuring the normal use of the equipment.

[0067] See Figure 3 In some embodiments, the light guide assembly 300 includes a first light guide portion 310 and a second light guide portion 320. The first light guide portion 310 extends into the first through hole 110. The second light guide portion 320 is connected to the first light guide portion 310 and is disposed on the side of the first light guide portion 310 near the flicker sensor 200. One end of the first light guide portion 310 extends into the first through hole 110 of the housing 100, directly exposed to the external light environment, for directly capturing light. The first light guide portion 310 and the first through hole 110 cooperate to form an optical seal, preventing external dust and liquids from entering the housing 100, while also providing a certain positioning for the entire light guide assembly 300. The second light guide portion 320 is located on the side of the first light guide portion 310 near the flicker sensor 200; the two are integrally molded by injection molding or bonded with optical adhesive to form a continuous light path.

[0068] See Figure 3 In some embodiments, the second mounting plate 600 includes a second mounting body 610 and a first protruding ring 620. The first protruding ring 620 is disposed on the second mounting body 610 and on the side away from the first mounting plate 500. The housing 100, the first protruding ring 620, and the second mounting body 610 enclose and construct a first cavity 621. The second light guide portion 320 of the light guide assembly 300 is disposed in the first cavity 621. Through the above arrangement, the second mounting body 610 is fixed on the housing 100, providing installation space for the light guide assembly 300. The second light guide portion 320 of the light guide assembly 300 is embedded in the first cavity 621, preventing the second light guide portion 320 from shaking and improving the installation stability of the light guide assembly 300.

[0069] See Figure 3In some embodiments, the second mounting plate 600 further includes a second convex ring 630, which is disposed on the second mounting body 610 and on the side away from the first mounting plate 500. The light guide assembly 300 abuts against the second convex ring 630 on the surface away from the flicker sensor 200. The second light guide portion 320, the second convex ring 630, and the second mounting body 610 enclose and construct a second chamber 631, in which the light-diffusing sheet assembly 400 is mounted. The second convex ring 630 and the first convex ring 620 may be concentrically arranged, with the top of the second convex ring 630 lower than the first convex ring 620, ensuring that the second light guide portion 320 of the light guide assembly 300 abuts against the top of the second convex ring 630. The inner diameter of the second convex ring 630 is adapted to the light-diffusing sheet assembly 400 of the light-diffusing assembly, allowing the light-diffusing sheet assembly 400 to be stably embedded in the second chamber 631. Simultaneously, the second chamber 631 provides a certain degree of dust protection for the light-diffusing sheet assembly 400.

[0070] In some embodiments, the light guide component 300 has a different transmittance than the housing 100. The transmittance of the light guide component 300 may be greater than that of the housing 100. The lower transmittance of the housing 100 helps to limit stray light from entering the interior of the housing 100 and protects other optical components inside the housing 100.

[0071] In some embodiments, the light guide assembly 300 has a different light transmittance than other light-transmitting components on the housing 100.

[0072] Understandably, different materials with varying light transmittance can be selected to manufacture the light guide assembly 300 and other light-transmitting components on the housing 10, depending on different needs. These other light-transmitting components may include the aforementioned light-diffusing components, such as the light-diffusing sheet group 400, or a lens module (not shown in the figure). This allows the strobe sensor 200 to more easily receive ambient light and respond to it more proactively. Consequently, when the user uses the image capture device, the strobe sensor can control the banding of the image, thereby improving the image quality.
