Abstract
Description
Technical Field
[0001] This invention relates to the field of relief photograph technology, specifically to a color relief photograph frame. Background Technology
[0002] Traditional photo frames and display methods primarily rely on flat printed photographs, where colors depend on the reflected light from the surface ink or dye layer. While these photographs can reproduce the basic information of an image, their color representation remains on the surface of the material, lacking a sense of light penetration and gradation, making it difficult to convey a sense of three-dimensionality and spatial depth. Furthermore, ordinary photographs are prone to reflections, glare, or color distortion under normal lighting conditions, limiting viewing angles and resulting in insufficient overall artistic expression.
[0003] To address the issue of monotonous display effects, existing technologies attempt to enhance texture through methods such as lamination, mounting, or adding surface textures. However, these methods still fail to overcome the limitations of planar imaging, lacking interaction between light and color to create a transparent and profound visual experience. Furthermore, traditional picture frames lack active lighting structures inside, making it difficult to significantly improve the color saturation and transparency of the photograph even with external light sources. Summary of the Invention
[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art, thereby providing a color embossed photo frame.

The lighting system includes a touch switch, a control board, and a light strip. The touch switch and the light strip are both connected to the control board. The embossed panel includes a base layer, a solid color layer, and a brightness adjustment layer sequentially arranged from the side closest to the light strip. The base layer is used to uniformly scatter backlight or ambient light and provide a high-brightness base. The brightness adjustment layer is used to adjust the contrast of local areas of the image and the physical shading of extremely dark areas.
[0006] Furthermore, the solid thickness of the solid color layer satisfy: ;in, The primary color concentration value of the target pixel; The light transmission distance of the color consumable; This is the compensation coefficient for ambient light or backlight intensity.
[0007] Furthermore, the number of printing layers of the solid color layer satisfy: ;in, The solid thickness of the solid color layer; The height of a single printed layer for the solid color layer; This is the rounding function.
[0008] Furthermore, the compensation coefficient for the ambient light or backlight intensity The value range is 0.5 to 1.5.
[0009] Furthermore, the photo frame also includes an embossed panel opening, which is located on the side of the photo frame body.
[0010] Furthermore, the photo frame also includes a hook groove, which is located on the back of the photo frame body.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0023] like Figures 1-3The illustrated color embossed photo frame includes: a photo frame body 5, within which an embossed plate 7 and a lighting system are sequentially arranged. The lighting system includes a touch switch 8, a control board 9, and a light strip 10. The touch switch 8 and the light strip 10 are both signal-connected to the control board 9. The embossed plate 7 includes a base layer, a solid color layer, and a brightness adjustment layer sequentially arranged from the side closest to the light strip 10. The base layer is specifically a white base layer W, which serves as a base diffuser to uniformly scatter backlight or ambient light and provide a high-brightness base. The brightness adjustment layer is specifically a black or gray layer K, used to adjust the contrast of local areas of the image and the physical shading of extremely dark areas. The solid color layer includes a cyan layer C, a magenta layer M, and a yellow layer Y. The solid color layer serves as a subtractive color filter layer for the three primary colors. The thickness of each layer is not uniform; instead, the absorption of corresponding wavelengths of light is controlled by the surface undulations, i.e., changes in local thickness. The greater the thickness, the deeper the corresponding color appears, i.e., the lower the light transmittance.
[0024] The aforementioned colored embossed photo frame, by setting an embossed plate 7 and a lighting system inside the photo frame body 5, allows the colors to shine through from the inside, giving it a sense of depth and transparency. Furthermore, the setting of the base layer, solid color layer and brightness adjustment layer further realizes the coupling of color and geometric depth, forming a transparent and profound visual experience.
[0025] like Figures 1-3 As shown, in this embodiment, the solid thickness of the solid color layer... satisfy: ;in, This represents the concentration value of a specific primary color for the target pixel, ranging from 0% to 100%. The light transmission distance of the color consumable is measured in millimeters. This refers to the compensation coefficient for ambient light or backlight intensity; the light transmission distance of a color consumable more specifically refers to the maximum physical thickness, in millimeters, of the color consumable through which light can pass without significant color distortion or complete obstruction of the light, representing the physical thickness of a certain color layer within a localized area. Its color density value It is directly proportional to its light transmission distance. In contrast, traditional solutions only perform simple linear thickness mapping, which leads to the separation of color and geometry. This makes it impossible for color information to directly drive the formation of geometry. Even if different colors have the same brightness, they will be regarded as the same height under linear mapping, losing the depth or material distinction implied by the hue difference. However, through this non-linear thickness mapping calculation, color synthesis is achieved by utilizing the optical properties of solid materials. The final color perception of the model depends on ambient light, realizing the deep coupling of color and three-dimensional volume, resulting in a deep and transparent visual effect.
[0026] like Figures 1-3 As shown, in this embodiment, the number of printing layers for the solid color layer is... satisfy: ;in, The solid thickness of the solid color layer; The height of a single printed layer for the solid color layer; This is a rounding function; the rounding function rounds the total number of printing layers to the nearest integer before printing, controlling the number of printing layers at each coordinate point (x, y). This creates a three-dimensional thickness distribution, which is also known as relief undulation.
[0027] like Figures 1-3 As shown in this embodiment, the compensation coefficient for ambient light or backlight intensity... The value range is 0.5~1.5; the compensation coefficient can non-linearly enhance local height differences, offset the flatness caused by ambient light, and can also adjust the thickness mapping in reverse: make the originally thinner areas appropriately thinner to increase light transmission, and make the thicker areas appropriately thicker to reduce light transmission, so as to form clear and natural light and dark layers under backlight. By adding an adjustable compensation coefficient in the generation stage, it can be pre-optimized for typical lighting scenes, so that the relief panel 7 can still maintain a good sense of three-dimensionality and detail visibility under various lighting conditions.
[0028] like Figures 1-3 As shown, in this embodiment, the photo frame also includes an embossed plate opening 1, which is located on the side of the photo frame body 5. The photo frame body 5 is an integrally formed structure, which is integrally formed by FDM 3D printing without any adhesive interface. The embossed plate opening 1 facilitates the installation and removal of the embossed plate 7.
[0029] like Figures 1-3 As shown, in this embodiment, the photo frame also includes a hook groove 2, which is located on the back of the photo frame body 5. The hook groove 2 facilitates hanging the photo frame body 5 on the wall, enhancing its aesthetic appeal.
[0030] like Figures 1-3 As shown, in this embodiment, the photo frame also includes a bracket 3, which is hinged to the back of the photo frame body 5; the photo frame also includes a support 6, which is fixedly installed on the back of the photo frame body 5, and the bracket 3 and the support 6 are hinged; the support 6 and the photo frame body 5 are integrally formed, and the hinge supports multi-angle placement and folding on the desktop, enhancing the viewing experience.
[0031] like Figures 1-3 As shown, in this embodiment, the photo frame also includes a light mounting plate 11, and the object-separating touch switch 8, control board 9 and light strip 10 are all mounted on the light mounting plate 11; the light mounting plate 11 mainly provides mounting positions for the object-separating touch switch 8, control board 9 and light strip 10, and the light mounting plate 11 is installed inside the photo frame body 5.
[0032] like Figures 1-3As shown, in this embodiment, the photo frame also includes a charging interface 4, which is connected to the control board 9. The charging interface 4 is used to charge the lighting system. The system has a built-in rechargeable lithium battery as the basic power supply. The battery is directly electrically connected to the control board 9. The charging interface 4 is specifically a Type-C charging head, which is connected to the power input terminal of the control board 9. When an external power source is connected, the current flows through the charging management circuit inside the control board 9 to safely charge the lithium battery. When no external power source is connected, the lithium battery supplies power to the entire system through the control board. The object-separation touch switch 8 is connected to the control board. The signal input pins of board 9 are connected to enable contactless human-computer interaction. When the user touches a specific area of the frame, a trigger signal is generated and transmitted to control board 9. The output of control board 9 is connected to the light strip 10. Control board 9 has a built-in MCU microcontroller. After receiving the command signal from the touch switch 8, it controls the on / off state of the power circuit or adjusts the PWM duty cycle of the output current, thereby realizing the "on / off" and "brightness and mode adjustment" of light strip 10. In addition, it works with relief board 7 to produce color synthesis effect through thickness difference, presenting the best light and shadow perspective effect. In the process of generating the relief plate 7, image processing is performed first: input the target color image, RGB to CMY: C = 1 - R / 255, M = 1 - G / 255, Y = 1 - B / 255; thickness mapping: set T_min=0.1mm, T_max=1.0mm; 3D model generation: white base layer, 2mm thick, cyan layer, magenta layer, yellow layer, relief shell; finally, the photo frame body 5 is FDM 3D printed, and then internal components such as the partition touch switch 8, control board 9 and light strip 10 are installed.
[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
