Therefore, various changes and modifications to the present invention should be apparent to and can be easily accomplished by those skilled in the art without departing from the spirit and principles of the present invention.

According to an embodiment of the present invention, referring to FIG. 1 , a system 10 capable of generating projected light includes a sensing module 100 , a control module 200 , and a display module 300 . The sensing module 100 is configured to sense light information F of ambient light AL. Specifically, the sensing module 100 can be set in any specific environment, and sense the ambient light AL of the specific environment, so as to obtain the light information F of the ambient light AL. For example, the light information F of the ambient light AL may include the direct light angle, the direct light intensity, the direct light color temperature, the diffuse light intensity, the diffuse light color temperature, or a combination thereof. In addition, ambient light AL refers to the comprehensive performance of light in an actual specific environment, and is not limited to sunlight, other natural light or artificial light. As mentioned above, according to the present embodiment, the sensing module 100 of the system 10 can transmit the light information F to the control module 200 of the system 10 after obtaining the light information. Next, the control module 200 receives the light information F of the ambient light AL sensed by the sensing module 100, and generates a projected light signal N according to the light information F. Then, the control module 200 transmits the projected light signal N to the display module 300 .

According to some embodiments, the control module 200 may include an electronic control circuit with a single-chip microcontroller (MCU), such as Arduino, ARM, Raspberry Pi, etc., to receive the light information F, and can use commercially available Windows/Android/ SoC and other systems write logic control programs to analyze and judge the light information F and generate the projected light signal N. However, the embodiments of the present invention are not limited thereto as long as the above-mentioned actions and functions can be realized.

Continuing from the above, the display module 300 can generate a projection light PL, and adjust the optical properties of the projection light PL according to the projection light signal N. That is, the display module 300 can generate the projection light PL corresponding to the light information F. For example, the sensing module 100 can obtain light information F including direct light angle, direct light intensity, direct light color temperature, diffuse light intensity, and diffuse light color temperature, which reflect the optical properties of ambient light AL. Next, the control module 200 generates the projection light signal N after receiving the light information F, and causes the display module 300 to correspondingly generate the projection light PL corresponding to the direct light and the diffused light. Wherein, the direct light itself and/or the illuminated place of the projection light PL generated by the display module 300 may have a light exit angle corresponding to (for example, the same as) the direct light angle, direct light intensity, and direct light color temperature in the light information F , light intensity, and light color temperature, and the diffuse light itself and/or the irradiated place of the projection light PL generated by the display module 300 may have the diffuse light intensity and diffuse light color temperature corresponding to (for example, the same as) the light information F illuminance and color temperature. Thereby, the display module 300 disposed in the predetermined space can simulate the ambient light AL of the specific environment to project, so that the predetermined space can have light projection and/or light and shadow changes similar to or the same as the ambient light AL of the specific environment. .

According to an embodiment, the direct light can be, for example, but not limited to, simulate sunlight directly projected through a window or sprinkled onto the ground, and according to the actual specific environment, the light output capability of the display module 300 and the distance from the display module 300 can be, for example, but not limited to Not limited to having 2000 lux to 20000 lux illumination. In addition, the diffused light can be, for example, but not limited to, simulate weak sunlight or indoor lighting that brightens the overall environment, and can be based on the actual specific environment, the light emitting capability of the display module 300 and the distance from the display module 300, such as but not limited to Not limited to having illuminance from 0 lux to 1200 lux. For example, diffuse light in an interior simulating a convenience store may be about 800 lux, and diffuse light in an interior simulating a typical home may be about 200 lux, although the invention is not limited to these scenarios. On the other hand, according to some embodiments, direct light is light with higher illuminance than diffuse light, and may have an illumination range or limited illumination angle recognizable by human eyes; and diffuse light is light with lower illuminance than direct light. The light may be irradiated uniformly or widely, without an illuminating range recognizable by the human eye or having a relatively wide illuminating angle.

Next, referring to FIGS. 2A to 2C , according to an embodiment of the present invention, the sensing module 100 may be configured to include a sensor array 110 , for example. Wherein, the sensor array 110 may have a plurality of sets of sensors 105, and each set of the plurality of sensors 105 is configured to independently sense the optical properties of the received ambient light AL. For example, each set of sensors 105 may have a color temperature sensor and an illuminance sensor, or may have a color temperature and illuminance integrated sensor that can simultaneously sense color temperature and illuminance, or the like. Alternatively, it can be a color temperature sensor, and the raw information sensed for sensing the color temperature can be used to convert and calculate the illuminance and the like. As mentioned above, each set of sensors 105 may actually have a single or a plurality of sensing elements for detecting different optical properties, and a set of sensors 105 is used as the basic unit for detecting optical properties in the sensor array 110 . In addition, in the case where each set of sensors 105 has a plurality of sensing elements for detecting different optical properties, the sensing elements may be integrated or separated. On the basis of the above, on the basis that each group of sensors 105 can be used as a basic unit for detecting optical properties in the sensor array 110, the specific configuration and composition of each group of sensors 105 according to various embodiments of the present invention are not limited to Examples described above.

Based on the above, based on the optical properties of the ambient light AL received and sensed by the plurality of sensors 105 located at different positions and at different angles, the possible optical properties of the ambient light AL in the overall specific environment can be estimated. Optical Information F. For example, the direct light angle of the ambient light AL is calculated by the positions (eg coordinates) of several sets of sensors 105 that receive the direct light of the ambient light AL, and the optical illuminance and optical illuminance sensed by the several sensors 105 The color temperature is used to calculate the direct illuminance and direct light color temperature of the ambient light AL. In addition, the diffused illuminance and diffused light color temperature of the ambient light AL are calculated by averaging the optical illuminance and optical color temperature sensed by all groups of sensors 105 that receive the diffused light of the ambient light AL. However, the above are only examples, and the present invention is not limited thereto.

Specifically, as shown in FIGS. 2A to 2C , the sensing module 100 may include a bowl-shaped container 120 made of an opaque material, having an inner surface 121 and defining a container opening 125 . The plurality of sensors 105 can be annularly disposed on the inner surface 121 of the bowl-shaped container 120 . In addition, the sensing module 100 is made of an opaque material and completely corresponds to the container opening 125 . The installed baffle structure 130 . For example, the baffle structure 130 may cover the container opening 125 of the bowl-shaped container 120 similarly to a lid. According to some embodiments, with the above-mentioned configuration, the baffle structure 130 may be integrally formed with the bowl-shaped container 120 , or may be a combination of different components, and the present invention is not limited thereto. As mentioned above, the baffle structure 130 can seal the entire container opening 125 , and corresponding to the center of the container opening 125 , the baffle structure 130 can define an opening 135 that communicates with the interior of the bowl-shaped container 120 . Based on this configuration, ambient light AL can be incident on the inner surface 121 of the bowl-shaped container 120 through the opening 135 , and each group of the plurality of sensors 105 can be configured to independently sense the received transmission opening. Optical properties of the ambient light AL incident on the aperture 135 .

On the other hand, according to some embodiments, the opening 135 can be formed in a circular shape, so that the incident ambient light AL can be incident through the opening 135 more uniformly. Additionally, according to some embodiments, the bowl-shaped container 120 may be formed as a semi-circular body or a semi-elliptical body. For example, referring to FIG. 3 in conjunction with FIGS. 2A to 2C , the bowl-shaped container 120 can be formed as a semi-elliptical body formed by rotating the lower half of the ellipse around the minor axis of the ellipse by 360 degrees, and correspondingly the container opening 125 is circular . However, the above is only an illustrative example of the implementation, and the present invention is not limited thereto.

Further, the size of the opening 135 is related to the arrangement density of the sensor 105, the moving range of the expected sensing light, the intensity of the direct light and the diffused light, etc., and those with ordinary knowledge in the art can configure it accordingly The size of the opening 135. On the other hand, according to an embodiment, in order to avoid that the opening 135 is too large to reduce the detection accuracy of light movement, and to avoid that the opening 135 is too small to reduce the amount of incident light or the requirement of the sensor density is too high, as shown in FIG. 3 As shown, in the semi-elliptical shape of the cross-section of the bowl-shaped container 120 formed as a semi-elliptical body and substantially perpendicular to the setting surface of the bowl-shaped container 120, the diameter d1 of the opening 135 may be equal to or smaller than the semi-elliptical shape of the cross-section. The distance between the two focal points f1, f2, but not limited to this. For example, the opening 135 formed corresponding to the center O of the container opening 125 may be formed between the two foci f1 and f2 of the semi-elliptical shape of the cross section. Further, according to some embodiments, the ratio of the area of the opening 135 to the area of the container opening 125 may be between 2% and 25%. For example, the proportion of the openings 135 can be set based on the condition that the illumination area can cover at least three sets of sensors 105 after the ambient light AL is injected into the bowl-shaped container 120 through the openings 135 , but the invention is not limited thereto.

In addition, referring to FIG. 3, the ratio of the short-axis length b of the semi-elliptical shape of the cross-section of the pot-shaped container 120 substantially perpendicular to the setting surface of the pot-shaped container 120 relative to the long-axis length a may be between 0.67 and 1. . Continuing from the above, under the above configuration, the ambient light AL incident on the inner surface 121 of the bowl-shaped container 120 through the opening 135 can have a more average coverage number or coverage density of the sensors.

For example, as shown in FIG. 4 , the plurality of sensors 105 may be disposed on the inner surface 121 of the bowl-shaped container 120 in a ring-like configuration close to a pentagonal icosahedron. Alternatively, although not shown in the drawings, the plurality of sensors 105 can also be arranged in the form of a regular icosahedron or the like and annularly disposed on the inner surface 121 of the bowl-shaped container 120 . As mentioned above, the above are only examples, and in the case that the angle or position of the sensed ambient light AL can be determined by the configuration of the sensor array 110, the plurality of sensors 105 can be formed by any form or array. configuration, and the present invention is not limited thereto.

Further, referring to FIG. 5A , according to the sensing module 100 ′ of other embodiments of the present invention, the above-mentioned bowl-shaped container 120 may also be an octahedron, or any shape not shown in the drawings of the present invention, and a plurality of sensors The detector 105 can be annularly disposed on the inner surface 121 of the bowl-shaped container 120 . Thereby, the ambient light AL incident through the opening 135 at different angles can be sensed based on the sensors 105 at different positions, and the angle of the sensed ambient light AL can be determined by the configuration of the sensor array 110 or Location. As mentioned above, the bowl-shaped container 120 of the present invention is not limited to the shape examples shown in the drawings.

5B , according to the sensing module 100 ″ of some embodiments, the baffle structure 130 ′ completely corresponding to the container opening 125 may also be larger than the entire container opening 125 and protrude or extend outward. For example , according to the present embodiment, the baffle structure 130 ′ may cover the entire container opening 125 and extend beyond the container opening 125 , and has a plurality of brackets 131 relatively extending downward from the protruding baffle structure 130 ′, so as to be established in the sense of The setting surface of the sensing module 100" assists in supporting and stabilizing the sensing module 100". On the basis of the above, under the condition that the ambient light AL can be incident through the opening 135 to distinguish the incident angle, the bowl shape according to the various embodiments of the present invention The forms of the container 120 and the baffle structure 130' are not limited to the examples specifically shown herein.

Step S100 is a height illumination group detection step, which is based on a predetermined number of groups (for example, three groups) as a unit of a group G to detect any specific one formed by different adjacent groups of sensors 105 Whether the specific average illuminance of the ambient light AL sensed by the group G is greater than twice the average illuminance of the ambient light AL sensed by all the groups G formed by the other groups of sensors except the specific group G, if not, directly Enter step S400, and if yes, then determine that the specific group G is the height illumination group G', and continue;

Step S200 is a direct light group determination step, which determines the direct light group G0 receiving the direct light 510 of the ambient light AL from one or more height illumination groups G', and if it is determined that there is no direct light group G0 Go directly to step S400, and if so, continue;

Step S300 is a step of capturing the direct light information, which captures the average sensing result of the optical properties of the ambient light AL sensed by the direct light group G0 as the information relative to the direct light 510 in the light information F, and based on the direct light The position of the group G0 is used to capture the direct light angle in the light information F. If it is determined that there is no direct light group G0, the information relative to the direct light 510 in the light information F is not captured;

Step S400 is a step of capturing diffuse light information, which removes the results of the sensor 105 determined to be the direct light group G0 and extreme outliers (for example, the sensor 105 may be faulty, too dark, too bright, directly directed by laser light, etc.) ) of the other sets of sensors 105, the average sensing result of the optical properties of the ambient light AL sensed by the sensor array 110 is captured as the information relative to the diffused light 520 in the light information F.

To sum up, the sensing step S10 can be implemented through the above steps S0 , S100 , S200 , S300 and S400 , so that the light information F of the ambient light AL is sensed by the sensing module 100 . For example, direct light angle, direct light intensity, direct light color temperature, diffuse light intensity, diffuse light color temperature, or a combination thereof. However, the above is only an example, and the details of the sensing step S10 in other embodiments of the present invention are not limited thereto.

According to another embodiment of the present invention, referring to FIG. 13 , step S100 can be performed as described above in FIGS. 11 and 12 , and the specific implementation details of step S200 in the direct light group determination step include the following steps:

Step S210 is a quantity judgment step, which judges whether the number of the height illuminance group G' is single, if it is single, directly judges that the height illuminance group G' is the direct light group G0, and ends step S200 and enters step S300 , if it is plural rather than singular, continue:

Step S220 is a step of judging the dispersion, which judges whether the plurality of height illumination groups G' are adjacent, and if they are adjacent, it is judged that a highest illuminance group with the highest average illuminance among the plurality of height illuminance groups G' is: Direct light group G0 (step S221), and end step S200 and enter step S300; if not adjacent, then further determine the average of a highest illuminance group with the highest average illuminance among the plurality of height illuminance groups G' Whether the illuminance is greater than twice the average illuminance of the primary high illuminance group with the next highest average illuminance among the plurality of height illuminance groups G' (step S222). Continuing from the above, if the average illuminance of the ambient light AL sensed by the highest illuminance group is more than twice the average illuminance of the ambient light AL sensed by the next highest illuminance group, then the highest illuminance group is determined to be the direct light group G0 ( Step S223), and end step S200 and enter step S300; and if the average illuminance of the ambient light AL sensed by the highest illuminance group does not reach twice the average illuminance of the ambient light AL sensed by the next highest illuminance group, it is judged No direct light group G0 exists, and the process ends step S200 and directly proceeds to step S400.

The above-detailed process of determining the direct light group is only an example, and other embodiments of the present invention are not limited thereto. As mentioned above, the direct light group of the ambient light AL sensed by the sensing module 100 can be determined according to any method, so as to perform other actions to obtain, for example, the direct light angle, the direct light intensity, the direct light color temperature, the diffuse light intensity, The light information F of the color temperature of the diffused light or its combination, and the corresponding projection light PL is projected. In addition, according to some embodiments, the generated projection light PL may include both the direct light 510 and the diffused light 520, or may only include the direct light 510 or the diffused light 520, or further include other types of projection light, and the present invention is not limited thereto the specified form.

Based on the above, the systems and methods according to various embodiments of the present invention can be applied to various scenarios or implemented in different application modes. For example, referring to FIG. 14, the systems and methods according to various embodiments of the present invention may be applied to simulate the scene and light and shadow changes of a fixed scene over time. For example, as shown in the left part of FIG. 14 , the display module 300 or 300' can display image information M corresponding to a specific environment in a predetermined space, and project a projection light PL having light information F synchronously corresponding to the image information M. Then, as time changes, as shown in the right part of FIG. 14 , the display module 300 or 300' can simulate the scene change and the light and shadow change corresponding to the time change. For example, the image information M in which the sun moves can be displayed, and the direct light 510 of the changing angle is projected correspondingly corresponding to the angle of direct light projected by the sun that changes position, and the diffuseness may be adjusted corresponding to the change of the color of the sunlight over time. The color temperature and illuminance of the incident light 520 make the overall scene and the effect and atmosphere created by the projected light and shadow closer to the specific environment where the ambient light AL is sensed and the image information M is captured.

Further, the system and method according to various embodiments of the present invention can also be applied to simulate the scene and light and shadow changes of a moving scene over time. For example, as shown in the left part of FIG. 15 , the display module 300 or 300 ′ can display the image information M corresponding to the context of a specific environment in a predetermined space, and project the projection light with the light information F synchronously corresponding to the image information M pl. For example, a situation corresponding to a specific environment where the locomotive is looking ahead and the train is moving forward along the tracks. Continuing from the above, with the time change and the change of the corresponding viewing angle and position, as shown in the right part of Figure 15, the display module 300 or 300' can simulate the scene change and the light and shadow change corresponding to the time change and the position angle change. For example, the image information M of the scene that can be seen from the position after driving forward along the track can be displayed, and corresponding to the influence of light and shadow changes (such as shading light or transmitting light) caused by the surrounding objects that change the scene. Projecting direct light 510 or diffused light 520 with changing angles or optical properties makes the overall scene and the effect and atmosphere created by the projected light and shadow closer to the situation of the specific moving environment where the ambient light AL is sensed and the image information M is captured.

In addition to the application modes and scenarios described above with reference to FIG. 14 and FIG. 15 , those skilled in the art should understand that the systems and methods of the embodiments can be correspondingly applied to various other application modes and scenarios according to the above principles. . For example, the system and method of the various embodiments can be used, so that people in Taiwan can watch and feel the scene and light and shadow changes of the actual environment of relatives and friends in a foreign country. Or, it enables passengers on cruise ships, space shuttles or any transportation vehicles to instantly watch and feel the scene and light and shadow changes of the specific environment that the transportation vehicle is currently passing through in a windowless room or in a safe space. In addition, multiple sets of matching scenes and light and shadow changes can also be established and set up for people to choose. As mentioned above, the modes and contexts of application of the systems and methods according to the present invention are not limited to those specifically set forth herein.

To sum up, the system and method according to various embodiments of the present invention can generate projection light reflecting ambient light of a specific environment, and may perform further levels of performance in conjunction with image information.
