Description

FIELD OF THE INVENTION

The invention relates to a display and lighting system, as well as to a space containing this display and lighting system. The invention also relates to a light control method provided for a posing person.

BACKGROUND OF THE INVENTION

It is known in the art to adapt lighting to create special effects. For example, US Pat. No. 7,070,228 proposes methods and devices for generating and modulating white light conditions. Examples of applications for which the aforementioned methods and devices can be implemented include retail environments (e.g., food, clothing, jewelry, paints, furniture, fabrics, etc.) or environments for the provision of services (e.g. , cosmetic, hairdressing, beauty salons, spas, photo salons, etc.), in which aspects of the observation of the goods / services offered are important for attracting the purchase of goods / services. Other applications include theatrical or cinema, medical and dental implementations, as well as transport (automobile) implementations. In another example, a personal care product includes at least one light source located near a mirror and configured to generate color-controlled lights, including essentially white light, the color temperature of which the user can control.

US 2010001654 describes a lighting system comprising a lighting unit, a human body signal receiving unit, a processing unit, and a lighting direction adjusting unit. The lighting unit directs the lighting light beam along the lighting direction; the human body signal receiving unit receives at least one human body signal issued by at least one user to accordingly generate an intensity signal; the processing unit receives an intensity signal and transmits a signal for controlling the direction of lighting in accordance with the intensity signal; and the lighting direction control unit receives a lighting direction control signal for automatically adjusting the lighting direction.

WO2009090600 describes the automatic creation of an environment, such as a lighting environment, combined with music that is suitable for a social setting and mood in an environment such as a room. An embodiment of the invention provides a system for automatically creating an environment suitable for a social environment and mood in the environment, comprising: an acoustic receiver for receiving sound from the environment and generating an audio signal representing the received sound, an audio signal processing unit for receiving and analyzing an audio signal for social surroundings and mood in the environment, and an environment creation unit designed to automatically generate control signals for the environment creation system in order to create an environment based on the result of the analysis of the audio signal. The mentioned system allows convenient and automatic creation of an environment suitable for social surroundings and mood in the environment, for example, premises.

SUMMARY OF THE INVENTION

A disadvantage of the known systems may be that these systems are not able to adapt the lighting in a convenient and intuitive way for specific applications, for example, applications in a fitting room, a room for hygienic care or in rooms for receptions and guests when people are watching themselves in the mirror.

Dressing rooms are rooms in which buyers decide whether to make a purchase and the lighting will affect how the customer perceives himself in the mirror, and therefore lighting is expected to be a major factor in influencing a positive decision regarding the purchase. The study shows that buyers may lose interest in clothing in the changing room if the lighting does not flatten them. Lighting that allows the buyer to see themselves in the best possible way will positively influence their buying decision. This application proposes to provide "flattering" lighting, for example, for the buyer, by actively adjusting the lighting so that the lighting gives maximum attractiveness (for the buyer).

There is a lot of information on how to give objects or people a more attractive look through lighting. Studio photographers use a variety of lighting equipment to make the model look as attractive as possible. However, in a studio setting, the photographer can fine-tune the lighting according to the location and shape and appearance of the model. In the fitting room or other similar areas, this setting is not possible. The above means that when creating a static flattering ambient lighting, this environment can be flattering only for people with a certain figure, skin tone and / or hair color.

This application can offer a solution to this problem by automatically adjusting the lighting according to the needs of the buyer in the fitting room (or in other places).

Therefore, an aspect of the invention is the provision of a display and lighting system, as well as a lighting system for a given display and lighting system, which in a preferred embodiment further at least partially eliminate at least one of the above-described disadvantages. An aspect of the invention is also the provision of an alternative light control method provided for a posing person.

In accordance with a first aspect of the present invention, there is provided a display and lighting system comprising a display unit, a sensor system, a control unit and a lighting system, wherein (a) the sensor system is configured to perceive a person in a predetermined area and generate a corresponding sensor system signal, ( b) the lighting system comprises (at least one) of (1) a first light source configured to provide front light for a person, and (2) W horn light source configured to provide overhead light for a person in a predetermined area, (c) the control unit is configured to obtain a person’s characteristics from a sensor and control system signal, based on the person’s characteristics, with light (at least one ) a first light source and a second light source, and (d) a display unit is configured to display an image of a person located in a predetermined area for a person in dvaritelno predetermined zone.

In this case, the display and lighting system, among other things, is determined as if a person was present in a predefined zone (see also below). As will be apparent to a person skilled in the art, a person is not part of a display and lighting device or lighting device, but is only described as part of systems, etc. for a deeper understanding.

A display and lighting system can provide a convenient and intuitive way to adapt lighting to light sources to produce “flattering” lighting for a person observing their image. For example, you can apply warm light when the sensor system recognizes white / light skin, and you can apply cold light when the sensor system recognizes dark / black skin. However, lighting can also be adapted if wrinkles (shadows on the face) can be recognized.

The term "display and lighting system" refers to a combination of devices and, in particular, refers to a specialized system of these devices. Devices can be connected by wire and / or wireless. The display and lighting system at least comprises a display unit, a sensor system, a control unit and a lighting system.

As mentioned above, the display unit is configured to display an image of a person located in a predetermined area for a person in a predetermined area. In other words, the person whose image is being created can observe his own image. Not necessarily excluded a situation in which the image can be observed by another person. For example, a display and lighting system may be combined with an access restriction system. However, in a particular embodiment, the display and lighting system is a standalone system without transmitting an image to a device or system different from the system to which the image relates. Thus, the phrase “display an image of a person located in a predetermined area for a person” and phrases similar to this phrase indicate that the person whose image is displayed is also able to see this image.

The term "person" refers, in particular, to one person (person), but in a particular embodiment, may also refer to many people (persons). The term "person" may refer to an adult or child and may refer to men or women. The term “image” may also refer to a plurality of (consecutive) images. Therefore, in a particular embodiment, the term “image” may also refer to video (a plurality of video images obtained over a period of time).

A situation is possible where it is necessary to instantly observe someone's image, but in some circumstances, it may also be necessary to provide a delay. Therefore, in some embodiment, the display unit is configured to display a human image with a predetermined or user-defined delay. Therefore, in some embodiment, the delay is configurable by the user (in particular, by the person himself). The mentioned delay can be used, for example, when a person wants to see his own back. It should be noted that this embodiment is applicable only to display units based on a display device (rather than a mirror; see below).

In one embodiment, the display unit comprises a mirror (to provide a mirror image of a person in a predetermined area), in particular, in one embodiment, the display unit is a mirror. An advantage of using a mirror is that the display and lighting device, or at least the display unit, can be relatively simple and cheap. In addition, the use of a camera to capture an image or images of a person is not necessary (but not excluded). The disadvantage may be that the image of a person cannot be (temporarily) saved, and therefore, the delay in displaying the image is not possible. Thus, the phrase “a display unit is configured to display an image of a person located in a predetermined area for a person in a predetermined area” may refer to a mirror representing a mirror image of a person in front of the mirror. Thus, the term “display,” as used in an embodiment, may refer to mirroring.

In yet another embodiment, the display unit comprises a display device (i.e., an electronic display device), such as a liquid crystal (LCD) or plasma screen. In these embodiments, the display and lighting system also comprises a camera for capturing at least one image of a person. This camera may be part of a common display and lighting system and / or may be contained in a display unit. Therefore, in a specific embodiment, the display unit comprises a camera for capturing a human image and a display for displaying a human image. In the aforementioned embodiment, the camera may be part of a sensor system and, therefore, may also serve to form a signal of the sensor system. In the latter embodiment, the camera can serve solely for capturing an image and displaying an image.

In this application, the term "sensor system" refers to a system that contains at least one sensor. However, the sensor may contain many sensors of various types. For example, the sensor system may include a camera configured with the possibility of human perception. This camera can provide information about many characteristics of a person. In one embodiment, the term “camera” may also refer to multiple cameras.

The sensor system is configured to perceive a person in a predetermined zone and generate the corresponding signal of the sensor system. The phrase “human perception” and similar phrases may refer to the perception of a specific characteristic of a person, for example, skin tone, body shape, mass, which can be performed, for example, by a specialized sensor. Additionally or alternatively, the phrase "human perception" and similar phrases may also refer to the formation of an image of a person and obtaining characteristics of a person from a given image.

Information (“human characteristics”) that can be obtained (in particular, by the control unit) from the cameras can be, for example, skin tone, wrinkles, skin heterogeneities, hair color, complexion, color of a person, and also the mood of a person (( unhappy) happy, hasty / calm, etc.), which can be obtained by facial expression, figure, age, gender, etc. Therefore, the term “human characterization” refers to the characterization of a given individual. In a particular embodiment, a person’s characteristic may also refer to a plurality of characteristics. The term “skin tone” may (also) refer, inter alia, to the reflectivity of the skin, the basic skin tone, complexion, skin gloss, and the like.

The term “human characterization” may also refer to a plurality of “human characterization”.

In a particular embodiment, the sensor system may comprise a second camera configured to perceive a person from a different position than the first camera (if any). The camera may be configured, for example, with the ability to capture at least one image from the back or side of the patient. In an embodiment in which the first camera is absent, for example, when a mirror is used, the “second” camera can also be configured to perceive a person from a different position than the display unit perceives.

Alternatively or additionally, the sensor system may comprise a skin tone sensor (configured to sense a human skin tone).

Alternatively or additionally, the sensor system may also contain at least one sensor for determining the mass of a person (mass sensor), a figure (figure sensor).

The sensor system may also include an RFID (Radio Frequency Identification) sensor, which can be configured to recognize the RFID chip of clothing located in an area, in particular, clothing worn by a patient. In a particular embodiment, the term “human characterization” may also refer to clothing (a piece of clothing or a piece of clothing) worn by a person.

The control unit is configured to obtain the characteristics of a person from the signal of the sensor and control system, based on the characteristics of the person, by the light of the first light source and (or) the light of the second light source. The control unit may comprise one central control unit, but may also comprise auxiliary control units. For example, a display unit, if it is based on a camera for display, may comprise a separate control unit for controlling the camera and display, while said separate control unit is configured to provide a very high quality image on the display.

If desired, the aforementioned auxiliary control unit can be configured to obtain the characteristics of a person from the sensor and transmit this information together with the sensor signal to the central control unit.

As used herein, the term “control unit” refers to at least a unit that controls light sources (see below) and optionally other devices (see also below), depending on at least one characteristic of a person ( see also below).

The control unit is configured to obtain human characteristics (optionally containing many human characteristics) from the sensor signal. Examples of human characteristics are, among others, the above characteristics.

In particular, the control unit is configured to control the light of the first light source and the light of the second light source (and optionally other devices), depending on at least one characteristic of a person selected from the group consisting of skin tone, skin heterogeneity, hair color, color of the item of clothing, facial expressions, moving a person in a predetermined zone, a person’s position in a predetermined zone, a figure, age, gender of a person.

In particular, the control unit may be configured to control at least one characteristic selected from the group consisting of light intensity, color temperature, color, saturation, color tone, beam direction and beam angle of at least one of a first light source and a second light source, and optionally an additional light source (see also below). In addition, the control unit may be configured to control at least one of the aforementioned characteristics of the light sources in interconnection. As mentioned above, the control unit can also control other devices (see also below).

The control unit can control the light source (s) and other additional devices wirelessly or by wire. In addition, the control unit may include a storage device configured to store at least one image. For example, storing at least one image can be used to display the image (s) with a delay. If desired, the control unit may also comprise a communication device for transmitting an image to an object external to the display and lighting system. For example, the control unit may contain a USB port or other ports. The control unit may comprise a Bluetooth communication device or other communication device for exchanging data at a distance (for example, using short-wave radio waves). The control unit may comprise, for example, at least one user input device for manually controlling, for example, at least one light source, image display delay (when used), and other devices (if any; see also below).

The control unit may also be configured to control an audio device, in particular based on a person’s characteristics. In addition, the control unit can be configured to control the light source (s) and other additional devices based not only on the characteristics of a person, but also on at least one other parameter, for example, time of day, day, week, month , year, season, sound, temperature, humidity, atmospheric pressure, etc.

The lighting system contains at least one light source. In a preferred embodiment, the term "lighting system" in this application refers to a system containing many light sources, which may be independent of each other, but of which at least two types operate under the control of a control unit. In this case, the lighting system preferably contains at least two types of different light sources, but may optionally also contain other types of light sources. The lighting system comprises at least a first light source (“front light”) configured to provide front light for a person, and / or a second light source (“downward light”) configured to provide an upper light for a person in predefined zone. In particular, front lighting can be formed from the same direction as the direction from which the person receives the image. The overhead light source or a second light source will generally be located at a height of at least about 2.5 m. In this case, light can be provided above a person.

With regard to the two types of light used, the upper light can provide general lighting and / or spherical lighting, and the front light can serve (in particular) to illuminate clothing worn by a person. In particular, the display unit may further comprise a first light source. Downward illumination from a second light source can contribute to adding depth to a person’s image displayed in a mirror or on a display. The first light source may, for example, illuminate dimming created by downward-facing light and an additional narrow-beam light (see below). In particular, the front light may be diffused front light. Front lighting can (therefore) reduce the visibility of wrinkles and other “flaws”. Therefore, the downward-facing light can be configured to provide general illumination, and the front light can be configured to illuminate dark areas. In a particular embodiment, the lighting system may comprise a single unit with multiple light sources. In a preferred embodiment, this single unit contains one or more light sources that are suitable as first light sources, and one or more light sources that are suitable as second light sources.

Optionally, the display unit comprises a light source that is suitable as a first light source, and the display and lighting system also includes at least one additional light source that is suitable as a first light source. Therefore, in one embodiment, the term “first light source” may also refer to a plurality of first light sources. Alternatively or additionally in another embodiment, the term “second light source” may also refer to a plurality of second light sources.

With respect to each of the first and second light sources, it is required that at least one characteristic selected from the group consisting of light intensity, color temperature, color, saturation, color tone, beam direction and beam angle be variable. In a preferred embodiment, at least one of the color temperature, color, saturation, and hue allows a change for at least one of the light sources. In addition, in a preferred embodiment, with respect to both the first and second light source, the intensity is required to be variable. In this application, the term "variable intensity" and similar terms refer to the possibility of changing the light intensity between the on and off states (with the existence of at least one light intensity setting between the on and off states )

Therefore, in a particular embodiment, the control unit is configured to control at least one characteristic selected from the group consisting of light intensity, color temperature, color, saturation, color tone, beam direction and beam angle of at least one from the first light source and the second light source, based on the characteristics of the person, in particular depending on at least one characteristic of the person selected from the group consisting of skin tone, wrinkles, inhomogeneities of the skin, hair color, color of the garment, facial expressions, movement of a person in a predetermined area, position of a person in a predetermined area, shape, age, gender of a person.

In embodiments in which the first light source comprises a plurality of first light sources, at least one of said characteristics can be controlled for each individual light source among the plurality of first light sources. However, the characteristics can also be controlled for at least one subset of the light sources among the plurality of first light sources. Similarly, in embodiments in which the second light source comprises a plurality of second light sources, at least one of said characteristics can be controlled for each individual light source among the plurality of second light sources. However, the characteristics can also be controlled for at least one subset of the light sources among the plurality of second light sources. In a particular embodiment, the display and lighting system or in particular the lighting system may further comprise a third light source with an adjustable light beam. In the present application, adjustment possibilities may relate to at least one of the beam angle and the beam direction, in particular to at least the beam direction. In this embodiment (s), the control unit is further configured to control the light of the third light source based on the characteristics of the person. Said third light source may be, for example, a narrow beam illumination lamp. Mentioned third light source can be used to increase brightness and / or, for example, to give a more healthy look to the hair. Furthermore, said third light source can be used to create contrast and / or to create a brilliant effect (in particular by using, for example, halogen lamps).

A “predetermined area” may be, for example, a floor area of a fitting room or a hygiene room, or the like. or part thereof. The term "predetermined zone" refers to a zone in which a person can take various poses, and this zone allows you to display an image of the person in question for a person located in a predetermined zone. The term "predefined zone" does not necessarily refer to the horizontal zone of the floor, but may also refer to virtual zones above the floor, located at any angle relative to the surface of the earth. If the display unit is a mirror, the predetermined area may be a zone substantially in front of the mirror.

In accordance with a further aspect, the invention provides a space comprising the display and lighting system described in this application. For example, the invention can be applied in a fitting room. However, the display and lighting system (in parts) can also be used in domestic conditions (a mirror in the bathroom or dressing room) for receiving guests (bathroom, ladies' and dressing rooms) and retail (hairdressers and beauty salons). Other applications can be, for example, (hotel) lobby, etc.

Therefore, in a specific embodiment, the space is a fitting room containing the display and lighting system described in this application. In yet another embodiment, the space is a reception and guest room comprising the display and lighting system described herein.

In a specific embodiment, the space may further comprise an object having a variable color, wherein the object having a variable color is located behind a predetermined area relative to the display unit, and the control unit is further configured to control the color of the object having a variable color, based on the characteristic person. In one embodiment, the additional accessory device comprises a given object having a changeable color, for example, a wall with a changeable color. For example, a wall or part of a wall located opposite the mirror or display of the display unit may comprise said object. For example, the color of clothing can be emphasized by adding colored light to the front lighting and / or adjusting the color of the (back) wall to a color complementary to the color of the clothing. An object may be, for example, a block such as a backlight unit, providing (diffused) (colored) “back lighting”. An example of an even lighting device is described, for example, in US Pat. No. 6,799,865.

In a particular embodiment, the display and lighting system may comprise a set of sensors (sensor unit), a computing unit (control unit), a display unit, in particular, a mirror and lighting equipment (lighting system). Sensors measure a person in a fitting room, for example, skin tone, hair color, clothing color, and contrast (wrinkles). Then this information is used to calculate the most flattering light for the buyer (posing person). For example, by constantly measuring and fine-tuning the lighting, an ideal setting is created that displays both the customer and the clothes that the customer wears in the best possible way. The proposed lighting system may consist of at least one means of diffused custom front lighting (light emitting diodes (LEDs) of cold white, warm white, red, green, yellow and blue), at least one, but preferably at least at least two directional and dimmable narrow-beam light bulbs, a wide-angle dimmable illuminator and a rear wall with a custom color.

The lighting system is also essentially part of the invention. This lighting system can be installed in a space containing a display unit, for example, a mirror. Therefore, in accordance with a further aspect, the invention provides a lighting system, for example, for use in the display and lighting system described herein, the lighting system comprising a sensor system, a control unit and a lighting system, wherein (a) the sensor system is configured with the ability to perceive a person in a predetermined area and generate the corresponding signal from the sensor system, (b) the lighting system contains a first light source and (or) a second light source , and (c) the control unit is configured to obtain the characteristics of a person from the signal of the sensor and control system, based on the characteristics of the person, the light of the first light source and the light of the second light source.

In accordance with a further aspect of the invention, there is also provided a method of controlling the light provided for a posing person, the method comprising (a) a step of perceiving a person in a predetermined area and generating an appropriate sensor system signal, (b) a step of obtaining a person characteristic from the sensor system signal , (c) the control step, based on the characteristics of the person, the light of the first light source configured to provide front light for the person in pre a given area, and (or) a second light source configured to provide a top light for a person in a predetermined area, and (d) a step of displaying an image of a person located in a predetermined area for a person in a predetermined area. This method can be applied, in particular, using the display and lighting system in accordance with the invention. Therefore, the present invention also provides the aforementioned method in which a display and lighting system is used in accordance with the description of the present application. The term "posing person" refers to a person who wants to see their display represented by a display unit, for example, in a mirror or on a display.

The term "essentially" in this application, for example, in the expression "essentially all radiation" or in the expression "essentially consists", should be understood by a person skilled in the art. The term “substantially” may also include embodiments with the terms “in whole”, “in full”, “in full”, and the like. Therefore, in embodiments, the definition can essentially also be excluded. In suitable cases, the term "essentially" may also refer to at least 90%, for example at least 95%, in particular at least 99%, mainly at least 99.5 %, including 100%. The term “comprises” also includes embodiments in which the term “comprises” means “consists of”.

In addition, the terms “first”, “second”, “third”, etc. in the present description and in the claims are used to distinguish between similar elements and not necessarily to describe a sequential or chronological order.

Below, by way of example only, a description is given of embodiments of the invention with reference to the accompanying schematic drawings, in which the corresponding positions indicate the corresponding parts and in which:

figure 1 schematically depicts an embodiment of a display and lighting system and changes of this embodiment; and

Figure 2 schematically depicts how, if necessary, a display and lighting system can be configured and operated.

DESCRIPTION OF PREFERRED EMBODIMENTS

Figure 1 schematically depicts a display and lighting system 100 that includes a display unit 110, a sensor system 120, a control unit 130, and a lighting system 140.

The sensor system 120 is configured to sense a person 1 in a predetermined zone 2 and generate a corresponding sensor system signal. In this case, the predefined zone 2 or even the entire floor 10 can be part of the fitting room, which is shown schematically in this figure. The space containing the display and lighting system 100 is indicated at 300.

The lighting system 140 comprises a first light source 141 configured to provide front light 41 for person 1 in a predetermined area 2, and a second light source 142 configured to provide front light 42 for person 1 in a predetermined area 2. First source 141 The light can be located, for example, on the wall 11, but can, for example, also be built into the display unit (see below). In figure 2, the first light source 141 is integrated in the display unit.

The control unit 130 is configured to obtain a human characteristic from the sensor system signal and configured to control, based on the human characteristic, the light 41 of the first light source 141 and the light 42 of the second light source 142. In addition, the display unit 110 is configured to display an image 5 of a person 1 located in a predetermined area 2 for a person 1 in a predetermined area 2; as can be seen in the figure, person 1 can see his own image 5 represented by the display unit 110. The display unit 110 may be, for example, a mirror, or may comprise, for example, a display device. In the latter case, the display and lighting system 100 will further comprise a camera for forming an image 5 of person 1. Therefore, a posing person 1 in a predetermined area 2 can see their own image 5.

Thus, FIG. 1 also schematically depicts an embodiment of the lighting system, indicated at 200, for use in the display and lighting system 100. The lighting system 200 comprises a sensor system 120, a control unit 130 and a lighting system 140, wherein (a) the sensor system 120 is configured to perceive a person 1 in a predetermined zone 2 and generate a corresponding sensor system signal, (b) a lighting system 140 in this a schematically depicted embodiment comprises a first light source 141 and a second light source 142, and (c) the control unit 130 is configured to obtain a human characteristic from a sensor and control system signal eniya, based on characteristics of the human, the light source 41 of the first light 141 and second light source 142 (and other accessories).

For example, in the present case, the sensor system 120 comprises a camera 121 and a skin sensor 122. Thus, for example, the sensor system 120 comprises a plurality of sensors. Camera 121 can be used to form an image 5 in the case of a display unit 110 containing a display device, but in addition or as an alternative, it can also be used to generate a sensor signal from which a human characteristic can be obtained.

In addition, for example, the display and lighting system 100 (and therefore also the lighting system 200) further comprises a third light source 143, preferably emitting an adjustable light beam 43. For example, it is possible to adjust the beam angle and / or beam direction. In such a case, the control unit 130 is preferably further configured to control the light 43 of the third light source 143 based on the characteristics of the person.

An additional camera (not shown), such as a second camera, may be arranged on the rear wall 12 or the side wall 13 to form an image of the person 1 from the side or from the back. It is also possible to use multiple second cameras.

The display and lighting system 100 (as well as the lighting system 200) may further comprise an object 150 having a variable color. In this case, the space 300 contains said object 150. For example, the rear wall 12 is said object 150. Object 150 may have a variable color. In this case, the object 150 is located behind the predetermined zone 2 relative to the display unit 110. In particular, the control unit 130 is further configured to control the color of the variable color object 150 based on the characteristics of the person.

Figure 2 schematically shows how a display and lighting system can function and exchange information. The control unit 130 receives information from the sensor (s) of the sensor unit 120, in this case, for example, a skin tone sensor 122 and an RFID sensor 123. In addition, an additional camera 121 can serve to create an image from which a person can be obtained. Optionally, the camera signal is processed by the auxiliary controller 131. From the sensor signals, the control unit 130 outputs at least one human characteristic and controls the light of the lighting unit 140. Optionally, the display and lighting system 100 may further comprise a memory 150 that can be used to store, at least one image, but which, in addition or as an alternative, can also be used to (temporarily) store user-defined data. For example, an RFID 123 sensor may receive a client code from a client card and check client settings in the library and / or receive client settings from a client’s RFID chip.

Therefore, the display and lighting system may employ a number of lighting adjustment methods. Different methods can be applied as separate solutions or in combination.

Skin tint: the spectrum of colors of light lighting can significantly affect a person’s self-image. The spectrum that should be used to create the most positive reaction in the fitting room is highly dependent on the skin tone of the user. By measuring skin color and adjusting lighting, the presentation of skin color can be adjusted to make the skin appear a little darker than in daylight. The same may apply, for example, to jeans. When blue is added to the lighting, the blue of the jeans will be emphasized. A sensor integrated in the mirror can measure skin color. This input signal is then used to adjust the front lighting by adding, for example, a little more red light and yellow light to make white skin appear tanned.

Reflection: in studio photography, narrow-beam lighting lamps are often used to add highlights to the appearance of the module. However, shiny skin will not look very attractive when brightly illuminated by a narrow-beam light. Therefore, it is proposed to measure the gloss of the skin and adjust the brightness of the narrow-beam lighting lamps to the ideal intensity.

Figure: for the proper illumination of the subject, the direction of the narrowly illuminated light bulbs is very important. Therefore, the camera should measure the shape and location of the buyer in the fitting room. When using directional lighting lamps of narrowly directed light, the light can be adjusted according to the person in the fitting room.

Back wall: In order to provide the most attractive appearance of clothing, it is important that the clothing differs sharply from the background. When you adjust the background color to an additional color to the color of the clothes, the clothes will really stand out from the background.

Heterogeneities: skin heterogeneities such as wrinkles or cellulite can be emphasized too much with downward light. The proposed solution forms the image of the skin, measures the contrast on the skin (the difference between the shadows from defects such as wrinkles) and adjusts the combination of front and lower lighting to a level ideal for the buyer.

The system may need to collect user data from the fitting room to determine the most appropriate scene. This problem can be solved using at least one of the following.

1. A scene adjustment system using the input signals of various sensors to determine the lighting configuration, which is the most flattering for the user of the fitting room.

2. A controlled lighting system that creates a scene formed by a scene setup system.

3. User-set data stored, for example, on a scanned loyalty card.

4. Measurement results from a specialized skin tone sensor in the locker room.

5. Information on clothing being tried on by detecting RFID tags on clothing.

6. Information from a computer vision system relating, for example, to a figure, hair / skin color, clothing, etc.

The system can be implemented in several ways, depending on the range of functions.

- For a fully functional system, you will need to use a computer vision system. A camera connected to computer vision software can control the fitting room. Since the fitting room is a fixed and controlled environment that differs from the standard, not additionally specified, user presentation area, this information can be used to conveniently evaluate the shape and position of the user (this task is usually called feature extraction or contouring). The system can further analyze the image by processing called color segmentation to identify the skin tone of the user, the color of the hair, and the primary colors present in the clothes.

- In a simpler system, the user can bring their skin into contact with a sensor to scan for skin pigmentation. These devices are commonly used in the cosmetic industry to determine skin tone, and these devices work by examining the spectrum of light reflected from the skin.

- These systems can be connected to a system that scans RFID tags on clothes to look for clothing colors from either the information stored on the tag or from a central database.
