Description

Conventionally, a screen (eg, an LCD screen) can alternately display an image for the left and right eyes in 3D operation (also referred to as a stereoscopic image) in rapid time series. By means of an infrared transmitter (which is located for example in an external USB device or integrated in the 3D screen), a synchronization signal can be sent to the shutter glasses. The shutter glasses can also have two LC surfaces. While the image for the left eye is displayed on the screen, the right lens is closed and the left lens is opened. While the image for the right eye is displayed on the screen, the left lens is closed and the right lens is opened. In other words, the left and right lenses can be opened in push-pull. When the conventional shutter eyeglasses 2400 are turned off or receive no synchronization signal 2401, both eyeglasses are opened (see FIG 24 ).

According to various embodiments, it has been recognized that in the viewer, in sum (over time), approximately half of the light arrives from the monitor because, viewed over time, each spectacle side is half opaque (closed). At the same time, only half of the ambient light (for example, reflections and / or backlighting) arrives at the viewer. Overall, everything looks vividly darker by half.

In general, image information (e.g., having a sequence of images) may be provided by means of an electrically driven image source, e.g. by means of a screen or a projector. The image source may be, for example, a stand-alone device, part of a stationary device (e.g., a computer) or part of a mobile device, e.g. a smartphone.

The image information to be transmitted is conventionally transmitted from the image source by means of light which can be picked up by a viewer. Conventionally used image sources can be roughly divided into two types, passive image sources and active image sources. A passive image source consists of a screen which has to be irradiated by externally generated light to make the image information visible. By contrast, an active image source generates and emits the required light itself. The larger the color spectrum and the contrast spectrum of the light that transmits the image information, the more information can be transmitted.

However, in a bright environment, the transmission of the image information may be affected by external influences, e.g. due to reflections and reflections of ambient light as well as glare due to backlighting.

Conventionally, a picture display 13 is viewed by a viewer 12 (cf. 1A ), the light 13 emitted by the image source 11 can be superimposed by stray light 14 and / or backlight 15 from the surroundings of the observer 12. The interfering light 14 and / or backlight 15 may be generated by an interfering light source in the environment of the observer 12, eg from the sun or a lamp, and reflected at the image source 11, such as the display of a mobile phone.

As a result, details with slight differences in brightness can be lost and thus remain hidden from the observer 12 (compare also 21 above).

Conventionally, the influence of the stray light is reduced by increasing the brightness and / or the contrast of the light transmitting the image information. However, the maximum displayable contrast and the maximum displayable brightness are limited by the performance of the image source and the light intensity that the viewer can record without being damaged. In a bright environment, therefore, it may be difficult to reproduce the image information by means of the image source and / or to perceive the image information displayed thereby. Furthermore, an increase in the light intensity leads to a reciprocal decrease in the life of a battery in a mobile device. For example, the brightness of an image source can conventionally be reduced and / or controlled by means of a pulse width modulation (PWM).

Illustratively, the perceptibility of the image information can be improved or, for example per energy used to display this, by synchronizing a temporal timing of (eg background) illumination of the image source (eg a display) with the shutter glasses.

Illustratively, the light emitted by the image source, which transmits the image information, can be temporally filtered by means of shutter glasses, so that the proportion of the disturbing light (at the light arriving at the viewer) is reduced. Thus, lower brightness is needed to reproduce image information, saving power and / or enabling lower power devices, which in turn are cheaper to manufacture. Furthermore, a conventional image source, e.g. a liquid crystal display (LCD), are considered low loss in intense ambient light, which protects the eyes and the range of applicability of a display device, e.g. a mobile phone or a navigation device, increased, especially in the field.

As a command, according to various embodiments, at least one signal pulse (i.e., a single signal pulse or a group of signal pulses) may be understood which define and / or effect a change in the shutter glasses, e.g. a change in the optical properties of at least one glass region of the shutter glasses, e.g. both glass areas of the shutter glasses.

The first command, which brings the left glass area and the right glass area of the shutter glasses into a transparent state, can have at least one first signal pulse, which brings the left glass area into the transparent state or at least increases its transparency. Optionally (eg depending on the communication protocol), the right-hand glass region can be brought into the transparent state by means of the first signal pulse, or the first command can have at least one additional first signal pulse which brings the right-hand glass region into the transparent state or at least its transparency increased.

The second command, which brings the left glass area and the right glass area of the shutter glasses into an opaque state, can have at least one second signal pulse which brings the left glass area into the opaque state or at least reduces its transparency. Optionally (eg depending on the communication protocol), the right-hand glass region can be brought into the opaque state by means of the first signal pulse or the second command can have at least one additional second signal pulse which brings the right-hand glass region into the opaque state or at least its transparency reduced.

According to various embodiments, the image information may comprise a plurality of frames which are displayed in a pulsed manner, and each frame is displayed by means of (e.g., precisely) a radiation pulse, e.g. take place in succession. Optionally, at least some frames of the multiple frames may be similar, e.g. consecutive frames. Then the impression of a freeze frame can be clearly generated. Alternatively or additionally, at least some frames of the multiple frames may differ from each other, e.g. form a sequence of mutually different frames, i. which are displayed consecutively, in other words, successive frames can change (also called picture change). Clearly the impression of a moving picture can be created. For example, the frame rate, i. the rate at which a frame change occurs is less than the frame rate, i. the rate at which the frames are displayed.

According to various embodiments, a pair of shutter glasses may have two switchable glass areas (also referred to as right glass area and left glass area). Each glass region of the two glass regions (also referred to as shutter glass regions) may be configured to be switched between an opaque state (vividly opaque) and a transparent state (vividly transparent), e.g. by means of one or the control signal. For this purpose, the shutter glasses may have a control circuit (also referred to as glass control circuit) which is arranged to switch each glass area of the shutter glasses according to the control signal (also referred to as glass switching signal), e.g. by means of an electrical voltage.

Each glass region of the two glass regions may include or be formed of a liquid crystal surface (also referred to as LC surface), e.g. be switched electronically between permeable and impermeable. Furthermore, the shutter glasses may have a frame (also referred to as a socket) which supports the two glass areas (for example, with a positive fit). The frame may optionally include a retainer (e.g., earloop, nose pad, handle, or behind-the-head tether).

Optionally, the shutter glasses may have the control device. Alternatively, the control circuitry may include a communication interface (and / or communication circuitry for providing it), e.g. a contactless communication interface (also referred to as an air interface) for receiving the control signal (e.g., when the controller is provided outside the shutter glasses).

In general, a communication interface may or may not be provided by means of a communication circuit. In other words, a communication interface may be understood as a communication circuit which provides the communication interface and is arranged according to the communication mode of the communication interface (e.g., infrared or Bluetooth).

In general, the image information may be provided by means of an image signal. The image signal may include first data representing an image content of the image information. Further, the image signal may be second data which represent the display cycle of the image information (eg, their frame rate, frame rate, data rate, etc.). The second data may include, for example, a horizontal sync signal, a vertical sync signal, a clock signal, and optionally an indicator that identifies the image information as stereoscopic or monoscopic. The image signal may be provided by means of an image information source, for example by means of an image source internal image information source (such as a graphics processor) or by means of an image source external image information source (such as a player). For example, based on the image signal, a radiation source control signal (eg, a backlight control signal) may be provided for (pulsed) driving the radiation source of the image source according to the pulse characteristic (so as to control the radiation emission by which the image information is displayed). Further, based on the image signal, an imager control signal may be provided for driving the imager of the image source according to an image content of the image information.

According to various embodiments, the control signal (also referred to as shutter eyeglass control signal) by which the shutter glasses are driven may be provided based on the radiation source control signal. For example, the shutter control signal and the radiation source control signal may or may be synchronized, at least by means of the second circuit. Alternatively or additionally, the shutter control signal may be arranged such that the glass switching signal (e.g., for the right and / or left glass regions) is in common with the radiation source control signal.

For example, to control the shutter glasses (e.g., to drive the two glass areas), the radiation source control signal may be used or a signal synchronized therewith. Alternatively, the radiation source of the image source can be controlled by means of the shutter eyeglass control signal or a signal synchronized therewith. This can simplify the control electronics.

For example, the shutter control signal may be converted into the glass switching signal by means of the glass control circuit of the shutter glasses. Alternatively or additionally, the shutter control signal may comprise or be formed from the glass switching signal.

Optionally, the shutter glasses may include an additional circuit (also referred to as a modulation circuit) for modulating the shutter control signal and / or the glass switching signal. To provide the first subphase (s) and / or the second subphase (s), the glass switching signal (i.e., the signal by means of which the glass regions of the shutter glasses are switched) may be modulated, e.g. by means of the modulation circuit of the shutter glasses. The modulation circuit of the shutter glasses, for example, be part of the second switching circuit of the control device when the shutter glasses has the control device.

According to various embodiments, a pulsed signal (e.g., the image information displayed in a pulsed manner) may be understood as a train of pulses (also referred to as a pulse train), e.g. Radiation pulses or signal pulses. The pulsed signal may be characterized by its period T (e.g., duration of the display cycle or duration of the shutter cycle) or by a pulse rate f (pulse repetition frequency) which corresponds to the reciprocal of the period (f = 1 / T). Furthermore, the pulsed signal can be characterized by the height (pulse amplitude) and duration (pulse duration) of the pulses. One or each pulse may or may not be characterized by its pulse shape (e.g., a square pulse, sawtooth pulse, etc.). The pulsed signal may include or be formed of a periodically repeating pulse or jerk event (e.g., a pulse train), e.g. a radiation pulse, a voltage pulse or a command pulse.

According to various embodiments, the pulse duration may be changed or, e.g. by means of a pulse width modulation (PWM). By means of the PWM, an electrical and / or radiometric quantity (e.g., an electrical voltage) may be changed over time, e.g. be changed between two or more values. For example, at constant frequency, the duty cycle of a rectangular pulse can be modulated, ie the width of the pulses forming it can be changed.

According to various embodiments, the or each contactless communication interface (or contactless communication circuitry) may be configured to provide short range communication, e.g. for a communication range of less than about 50 meters.

According to various embodiments, the or each communication circuit may include a radio module (also referred to as a radio module) configured to convert between radio waves and an electrical signal (e.g., the control signal or the glass switching signal). By means of the radio waves, a contactless communication between two communication circuits may or may not be made, e.g. between the control device and the shutter glasses and / or between the control device and the image source.

According to various embodiments, the shutter glasses switching cycle may be arranged such that the left glass area and the right glass area of the shutter glasses are in the transparent state during successive radiation pulses and / or frames of the image information. Alternatively or additionally, the shutter glasses switching cycle can be set up such that the left glass area and the right glass area of the shutter glasses are between successive radiation pulses and / or frames of the image information in the opaque state. In other words, the image information displayed pulsed may have a display phase in which a single image is displayed (eg by means of the radiation pulses). The left glass area and the right glass area of the shutter glasses may be in the transparent state simultaneously with successive display phases. Alternatively or additionally, the left glass area and the right glass area of the shutter glasses may be in the opaque state between successive display phases.

According to various embodiments, the left glass area and the right glass area of the shutter glasses may be driven together, at least by means of a common glass switching signal (e.g., by means of exactly one glass switching signal). For example, the left glass area and the right glass area of the shutter glasses may be electrically connected together, e.g. by means of a common switching input or by means of a common electrode (or common electrode pair). Alternatively or additionally, the left glass area and the right glass area of the shutter glasses may be monolithically bonded together, e.g. by means of a common liquid crystal surface. Thus, the driving of the shutter glasses can be facilitated.

In general, the or each liquid crystal surface of the shutter glasses may comprise two electrodes (also referred to as electrode pair) between which an electric field may be applied, e.g. by means of the glass switching signal.

As an alternative to the common electrode or the common electrode pair, a plurality of electrode segments which are coupled to one another in an electrically conductive manner may be used, wherein the several electrode segments are driven together, e.g. by means of the same glass switching signal and / or by means of a common switching input.

According to various embodiments, the left-hand glass portion may be provided by (e.g., part of) a right-hand lens, and the right-hand glass portion may be provided by (e.g., part of) a left-hand lens. The right lens and the left lens may, for example, be spaced apart (e.g., located on opposite sides of the nose region) and / or provided by separate liquid crystal surfaces. Alternatively, the left glass portion and the right glass portion of the shutter glasses may be provided by a common lens. The common spectacle lens may, for example, extend over the nose region and / or be provided by means of a monolithic liquid crystal surface.

Herein, for ease of understanding, reference may be made to two glasses (i.e., a left and a right glass) of the shutter glasses, by means of which the function of the shutter glasses will be illustrated according to various embodiments. However, it can be understood that the right glass represents the right glass region and the left glass represents the left glass region, alternatively, the left glass region and the right glass region may also be collectively part of the same (monolithic) glass. In other words, instead of the left lens and the right lens, the shutter glasses may have a monolithic lens providing the function of the left lens and the right lens. The two glass areas of the common glass may, for example, be switched at the same time, which simplifies the control and / or the construction.

The nose pad can be understood as the area (also referred to as the nose area) of the shutter glasses, in which the glasses should rest on the nose bridge of a wearer. For example, the nose pad may be provided by means of a recess of the frame and / or a nose bridge. Optionally, the nose pad may have a nose pad or a plurality of nose pads. Alternatively, another support concept of the shutter glasses may be used instead of the nose pad, which does not necessarily require, for example, a resting of the nose pad on the nose. In general, the nose area of the shutter glasses may, for example, have the recess of the frame and / or the bridge of the nose in which the nose is to be received.

According to various embodiments, the shutter glasses may comprise a mask which surrounds the left glass and the right glass (eg laterally), eg a sealing edge. The mask (also known as a sunscreen mask, eg sun protection mask) can put on a reduced gap between the face of the viewer and the shutter glasses and thus reduce lateral light. For example, the shutter glasses in the form of a Ski goggles be or become. Thus, the perceptibility of image information can be further improved.

According to various embodiments, the shutter glasses may include a sensor (also referred to as a wear detection sensor) configured to detect (also referred to as a wearer recognition) whether the shutter glasses are being worn. For example, the control device may be configured to control and / or regulate the driving of the two glasses or the common glass and / or the image source on the basis of the carrying recognition.

According to various embodiments, the second circuit may optionally be arranged to maintain or interrupt (e.g., turn on or turn off) the driving of the two lenses of the shutter glasses (e.g., providing the control signal), e.g. based on the wearer's recognition. For example, the two glasses of shutter glasses may be driven in accordance with the shutter glasses switching cycle if (for example, so long) the shutter glasses have detected the shutter glasses. Alternatively or additionally, the two glasses of shutter glasses may be or remain in a steady state or inactive state when (for example, so long) it has been detected by the wear detection sensor that the shutter glasses are not being worn. For example, the shutter glasses may be or remain inactive if (for example, so long) the wear detection sensor has detected that the shutter glasses are not being worn.

According to various embodiments, the second circuit may optionally be configured to maintain or interrupt the driving of the image source (e.g., providing the additional control signal) (e.g., turn it on or off), e.g. based on the wearer's recognition. For example, the image source may be or may be driven by the controller when (for example, so long) it has been detected by the wearer sensor that the eyeglasses are being worn. Alternatively or additionally, the image source may be or remain in a self-controlled state and / or uncontrolled state when (for example, so long) the wear detection sensor has detected that the shutter glasses are not being worn.

According to various embodiments, the control device (e.g., when implemented in the shutter glasses) may be configured for bi-directional communication with the image source, such as when the default is changed by means of the positioner.

According to various embodiments, the identification tag may be displayed regardless of the content of the image information and / or regardless of the orientation of the image information.

According to various embodiments, the identification tag may encode the information about the pulse characteristic, e.g. chromatic, digital, pulsed and / or bitwise. Alternatively or additionally, the identification mark may be displayed pulsed according to the pulse characteristic. For example, the identification mark can have one or more symbols by means of which the information about the pulse characteristic can be transmitted.

According to various embodiments, the pulse characteristic according to which the image information is displayed in a pulsed manner may be changed by means of a PWM, e.g. by means of the additional control signal. Alternatively or additionally, the shutter glasses switching cycle may be adapted to the PWM according to which the image information is displayed in a pulsed manner (e.g., with a predefined pulse duration ratio), e.g. by means of the control signal.

According to various embodiments, the display device may comprise an active image source, e.g. a light-emitting diode image source (LED image source) and / or an organic light-emitting diode image source (OLED image source). Alternatively or additionally, the display device may comprise a passive image source, e.g. a liquid crystal image source (LCD image source).

According to various embodiments, an energy saving (also by means of a control device) can be achieved with the same contrast or a higher contrast and / or brilliance can be achieved with the same energy.

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology such as "top", "bottom", "front", "back", "front", "rear", etc. is used with reference to the orientation of the described figure (s). Because components of embodiments can be positioned in a number of different orientations, the directional terminology is illustrative and is in no way limiting. It should be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. It should be understood that the features of the various exemplary embodiments described herein are combined unless specifically stated otherwise. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

In the context of this description, the terms "connected", "connected" and "coupled" are used to describe both a direct and an indirect connection (eg ohmic and / or electrically conductive, eg an electrically conductive connection), a direct or indirect connection and a direct or indirect coupling. In the figures, identical or similar elements are provided with identical reference numerals, as appropriate.

The term contrast may be understood as the ratio of the maximum radiance (e.g., luminance) to the minimum radiance (e.g., luminance) of a displayed frame, minus 1. Illustratively, the contrast can describe the difference between the brightest and darkest area / point of a single image.

According to various embodiments, the pulse characteristic may represent the time relationship between the active phase (in which the image source is lit) and the passive phase (in which the image source is not lit), which may also be referred to as the active-passive phase pulse ratio. The pulse characteristic may describe the pulse duration, the pulse rate and / or the pulse amplitude according to which the image information is displayed pulsed, i. the duration, frequency and strength of the active phase.

Clearly, the shutter glasses can be controlled such that their two glass areas are transparent in the active phase of the image source and be opaque in the passive phase.

According to various embodiments, a computer program product (eg, software) may be provided which, in conjunction with an image source adapter, ensures that an identification tag (eg, a white spot) is always affixed to the physical location on the image source adapter ) is displayed, which allows the image source adapter attached there at any time the detection of the pulse characteristic of the pulsed displayed image information (eg, the pulse width of the illumination). For example, if a video / movie is displayed on the display device and the image content is black at that physical location, the image source adapter may capture information about the pulse characteristic by means of the identification tag, for example, in the active as well as in the passive phase of the display device darkness prevails. If the display device has a mobile device, the computer program can optionally take into account its current orientation and / or display orientation, e.g. Portrait (e.g., upright or portrait) or landscape (e.g., Landscape) can not address only a fixed pixel position.

1A . 1B and 1C each illustrate a conventional method.

The emitted light 13 the image source 11 (see 1A ) can have a certain spatial brightness distribution 13a as shown in diagrams in 1B and 1C as brightness 105 along a section 11s is applied by way of example.

A local (eg punctiform) source of disturbing light can, for example, be the brightness distribution 13a the image source 11 from the view of the viewer 12 locally outshine 206 (compare also 21 ). In other words, in one area 21 . 203b in which the brightness 14a of the stray light 14 , greater than the brightness 13a the image source 11 , the image information of the image source 11 (eg in 203b) completely go under and thus the viewer 12 stay hidden.

A flat (eg diffuse) source of disturbing light can, for example, be the brightness 13a the image source 11 from the viewer's point of view 12 holistically outshine 206. In other words, the overall brightness distribution 13a the image source 11 from an approximately uniform Störhelligkeit 14a be superimposed, so that the resulting and the viewer 12 illustrative brightness distribution 15a (eg in 203c) a reduced contrast 22 having.

According to various embodiments, a selective suppression of electromagnetic radiation is provided, which reduces the influence of ambient light on the image quality (Störlichtreduktion). The Störlichtreduktion can be done by means of an active shutter glasses. Basically, the Störlichtreduktion can be done by means of the active shutter glasses regardless of the type of displayed image information. For example, the Störlichtreduktion done without a 3D representation is needed. In other words, the disturbance light reduction can be done both in a 2D operation and in a 3D operation of the image source used to display the image information. For example, the backlighting of the image source can be synchronized with the active shutter glasses, and optionally the LCD, to reduce the stray light.

According to various embodiments, an image source may be part of a stationary device (eg, a computer, a television, a monitor) or part of a mobile device (also called a Mobile device) may be, for example, a tablet, a mobile station, a laptop, a smartphone, a camera or a navigation device. The image source may be a passive image source and / or an active image source.

2A illustrates a method 200a according to various embodiments in a schematic side view.

The method may include emitting pulsed electromagnetic radiation 204 (also referred to as radiation pulses 204) according to image information in a receiver area 151 , The radiation pulses 204 For example, they may have electromagnetic radiation in the range of visible light, eg red light, blue light and / or green light. For example, radiation pulses 204 can be emitted which transmit the image information, for example in a display direction 111 (eg in the direction of the receiver area 151 ). Optionally, in the receiver area 151, a receiver 113 be arranged. The receiver may, for example, have a sensor, eg an organic sensor (eg an eye) or an inorganic sensor (eg an optoelectronic sensor). For example, the recipient may be a human viewer.

The emitting of the pulsed electromagnetic radiation 204 may include, for example: pulsed displaying of image information on an emitting surface 202 , eg by means of an electronically controlled image source. The electronically controlled image source may have a screen which shows the emission area 202 from which the pulsed electromagnetic radiation 204 is emitted. Alternatively, the electronically controlled image source may comprise a projector. The projector may be configured, for example, pulsed electromagnetic radiation on the emission surface 202 (eg, a projection surface), from which it is reflected (eg, diffused). Under reflection 204 Electromagnetic radiation can also (eg diffuse) remission 204 the electromagnetic radiation.

The procedure 200a may further comprise: filtering out of interference 206 . 208 (eg reflection 206 and / or backlight 208 ) from electromagnetic radiation 246u (also as unfiltered radiation 246u designated), which in the direction of the receiver area 151 is emitted by means of a shutter glasses 102 , In other words, the method may include: separating the interference radiation 206 . 208 from the image information or the pulsed radiation 204 (Also referred to as selective hiding the interference).

This can be the shutter glasses 102 between the emitting surface 202 and the receiver region 151 be arranged or become. The shutter glasses 102 may comprise two electronically switchable glasses, which are for example arranged to be switched between an opaque state and a transparent state. The electromagnetic radiation passing through the shutter glasses 102 passes through, can as filtered radiation 246g be designated.

Clearly, the unfiltered radiation 246u the radiation pulses 204 the image information (also as image information radiation pulses 204 designated) and, depending on the environmental influence, in addition, the interference radiation 206, 208 (zBZB backlight 208 , Stray light 206 or reflection light 206 ), which eg from the emission area 202 can be reflected. Using the shutter glasses 102 can at least part of the interference 206 . 208 be filtered out. For example, in the time interval, a ratio of interfering radiation 206 . 208 to radiation pulse 204 (Eg their radiation power) can be reduced by means of filtering out 222. In other words, a ratio of spurious radiation 206 . 208 to image information radiation pulse 204 (eg, its radiation power) on the unfiltered radiation 246u be larger than the filtered radiation 246g.

The ratio can be understood as averaged over time, e.g. over several display cycles.

The filtering out 222 the interfering radiation 206 . 208 using the shutter glasses 102 may include, for example: switching the two lenses of the shutter glasses 102 in the transparent state in a time interval in which a (eg radiometric or electrical) luminosity magnitude of a pulsed displayed image information meets a predetermined criterion; and (eg otherwise, eg before and / or after) switching the two lenses of the shutter glasses 102 in an opaque state.

The switching between the transparent state and the opaque state can be cyclic, i. repeated, e.g. as long as the image information is displayed and / or according to a shutter glasses switching cycle.

Illustratively, according to various embodiments, a picture content-independent driving the two lenses of the shutter glasses 102 respectively. This can simplify the driving and the control device.

3B illustrates a shutter glasses in a shutter glasses switching cycle 300s according to various embodiments in a schematic circuit diagram.

The shutter glasses switching cycle 300s may include: a first phase 301 in which a left glass 3021 and a right glass 302r the shutter glasses 102 are in a transparent state.

The shutter glasses switching cycle 300s may further comprise: a second phase 303 in which the left glass 3021 and the right glass 302r the shutter glasses 102 are in an opaque state.

In the transparent state can be a transparency of the left lens 3021 and the right glass 302r the shutter glasses 102 greater than in the opaque state, eg, about twice or more, eg, about three times or more, eg, about four times or more, eg, about five times or more, eg, about ten times or more.

The first phase 301 For example, it may be time for the second phase 303 adjacent, for example, if the left glass 3021 and the right glass 302r the shutter glasses 102 be switched simultaneously.

The switching of the left glass 3021 and the right glass 302r of the shutter glasses 102 can be done by means of the control signal 304s. Clearly, the filtering out 222 by means of the control signal 304s (also as a filter control signal 304s referred to), for example, controlled and / or regulated. The control signal 304s can vividly sync the shutter glasses 102 cause.

For example, the control signal 304s have a first command, which the left glass 3021 and the right glass 302r of the shutter glasses 102 essentially simultaneously brings in the transparent state. Alternatively or additionally, the control signal 304s have a second command which the left glass 3021 and the right glass 302r the shutter glasses 102 essentially simultaneously in the opaque state brings.

The shutter glasses switching cycle 400s can be set up, such as the shutter glasses switching cycle 300s , Alternatively or additionally, the control device 300a the control signal 304s 400 seconds according to the shutter glasses switching cycle.

The shutter glasses switching cycle 400s may have a third phase 305 (evidently a transitional phase) in which the left glass 3021 and the right glass 302r the shutter glasses 102 are in different states. One of the glasses 3021, 302r may be in an opaque state and the other may be in a transparent state.

The third phase 305 may be needed, for example, when the shutter glasses 102 or whose communication protocol does not support a command which the left glass 3021 and the right glass 302r switches simultaneously.

The first phase 301 and the second phase 303 For example, they may be spaced apart from each other, for example when the left-hand glass 3021 and the right glass 302r of the shutter glasses 102 be switched one after the other. Temporarily between the first phase 301 and the second phase 303 may be the third phase 305 be arranged. A duration of the third phase 305 may be less than a duration of the first phase 301 and / or as a duration of the second phase 303 eg less than 10% (eg less than 1%) of the duration of the first phase 301 and / or the second phase 303 ,

In other words, the third phase 305 switching between the first phase 301 and the second phase 303 ie, graphically, a transitional state between that between the first phase 301 and the second phase 303 represent. Switching to the third phase 305 can be done, for example, with twice the pulse rate of the image information.

For example, switching to the first phase 301 and / or the second phase 303 take place with the pulse rate of the image information. Alternatively or additionally, the switching between the first phase 301 and the second phase 303 with twice the pulse rate of the image information.

For example, the control signal 304s have a first command, which the left glass 3021 and the right glass 302r of the shutter glasses 102 one after the other into the transparent state. Alternatively or additionally, the control signal 304s have a second command which the left glass 3021 and the right glass 302r the shutter glasses 102 successively brings into the opaque state.

For example, the first command can have a first subcommand and an additional first subcommand. The first part command can be set up, the left glass 3021 in the transparent state to bring (also as an open partial command of the left glass 3021 designated). The additional first partial command can be set up, the right-hand glass 302r in the transparent state to bring (also as an open partial command of the right glass 302r designated). Alternatively or additionally, the second command can have a second subcommand and an additional second subcommand.

5 illustrates a method according to various embodiments in a schematic flow diagram 500a and a schematic diagram 500b , which is a (eg radiometric or electrical) luminosity size 205 the image information over time 601 illustrated. The radiometric (eg photometric) luminosity size 205 may be, for example, a radiation power, by means of which the image information is pulsed. The electrical luminosity size 205 (Eg, the radiation source control signal) may be, for example, an electrical voltage, an electric current or an electric power, by means of which the image information is pulsed.

The image information can be multiple frames 51a to 51i have or be formed of which, that is pulsed, ie one after the other and with a time interval 601d (ie measured from end to beginning) from each other. Each frame of the multiple frames 51a to 51i can by means of exactly one radiation pulse 204 are displayed. In other words, the electromagnetic radiation, by means of which the image information is transmitted, can have a plurality of radiation pulses 204 or formed therefrom, which are emitted one after the other and at a time interval from one another (eg from the emission surface 202).

Each frame of the multiple frames 51a to 51i can have a display duration 601P which, for example, the pulse duration 601P (temporal extension 601P of the respective radiation pulse), eg their value.

The time difference 601e (measured from beginning to beginning) between two consecutive frames 51a to 51i the image information can be the reciprocal of the refresh rate (may correspond to the pulse rate). The time difference 601f between two frames 51a to 51i , which differ from each other, may be the reciprocal of the frame rate. The duration of the shutter glasses switching cycle, for example, the time difference 601e consecutive frames 51a to 51i correspond.

The information 302i can be the (eg radiometric or electrical) luminosity size 205 For example, their time dependence (eg according to the PWM), eg the pulse duration 601p, the pulse amplitude (corresponds to the valley-to-peak value of the luminosity magnitude 205 ) the pulse rate and / or a combination thereof.

For example, the information 302i represent a time interval 601p in which the (eg radiometric or electrical) luminosity magnitude 205 the image information meets a predetermined criterion. The criterion can be met, for example, if the luminosity size 205 the image information has or exceeds a predetermined value and / or lies within a predetermined value range. The time interval 601P can then clearly the pulse duration 601P correspond, for example, about the half width of each radiation pulse 204 , Alternatively or additionally, the information 302i an additional time interval 601d represent in which the luminosity size 205 the image information does not meet the predetermined criterion, for example has a minimum value. The additional time interval 601d can clearly correspond to the time interval 601d of successive individual images or radiation pulses 204.

6 illustrates a method in a schematic flow diagram 600a and a schematic detail view 600b of the diagram 500b and a schematic diagram 600c, in which a transparency 207 (ie, transmissivity to electromagnetic radiation) of the left lens 302l of the shutter glasses 102 and the right glass 302r the shutter glasses 102 over time 601 is illustrated.

The method can be used to control a shutter glasses 102 (eg by means of a control device described herein) be established.

The method may include the shutter glasses 102 cyclically, eg according to a shutter glasses switching cycle 600s. The shutter glasses switching cycle 600s may be arranged as any of the shutter glasses switching cycles described herein, eg, shutter glasses switching cycle 300s or shutter glasses switching cycle 400s , Alternatively or additionally, the control device 300a the control signal 304s according to the shutter glasses switching cycle 600s provide.

The duration of the shutter glasses switching cycle 600s can the time difference 601e two consecutive frames 51a to 51i (measured from the beginning to the beginning of this) correspond to the image information.

Every shutter eye switching cycle 600s can (eg exactly) a first phase 301 and (eg, exactly) a second phase 303 exhibit. Optionally, the shutter glasses switching cycle 600s (eg exactly) two third phases 305 have, of which a third phase 305 between the first phase 301 and the second phase 303 is arranged and of which an additional third phase 305 between the second phase 303 and the subsequent shutter glasses switching cycle 600s, for example, between the second phase 303 and the end of the shutter glasses switching cycle 600s ,

According to various embodiments, the first phase 301 of the shutter glasses switching cycle 600s and the time interval 601p (also as the first phase 601P of the display cycle) overlap each other in time. For example, the first phase 301 the shutter glasses switching cycle 600s temporally in the time interval 601P lie. This can be the first phase 301 the shutter glasses switching cycle 600s be shorter in time (ie have a shorter duration) than the time interval 601P ,

According to various embodiments, the second phase 303 of the shutter glasses switching cycle 600s and the additional time interval 601d (also as a second phase 601d of the display cycle) overlap in time. Alternatively or In addition, the second phase 303 the shutter glasses switching cycle 600s have at least a period of time, which is temporally between two time intervals 601d (ie between the radiation pulses). For example, the additional time interval 601d in time in the second phase 303 of the shutter glasses switching cycle 600s lie. This can be the second phase 305 the shutter glasses switching cycle 600s be longer in time (ie have a longer duration) than the additional time interval 601d ,

For example, the second circuit 304 (see 3A ) a ratio of the duration of the first phase 301 the shutter glasses switching cycle 600s and the duration of the time interval 601P according to a specification (eg less than about 50%, eg less than about 25%, eg less than about 10%). The default, for example, a contrast 205k (also referred to as image contrast) of the filtered radiation 246g represents (compare 2A to 2C ). Alternatively or additionally, the specification may represent a radiation energy (eg its spatial distribution, eg a radiance), eg a luminance. The radiant energy or radiance can influence the brightness perceived by the viewer (image brightness).

Clearly, the smaller the ratio of the duration of the first phase, the greater the amount of interference radiation filtered out 301 the shutter glasses switching cycle 600s and the duration of the time interval 601P is (eg if the ratio is less than about 50%, eg less than about 25%, eg less than about 10%).

The transparency 207 of the left lens 302l of the shutter glasses 102 and the right lens 302r the shutter glasses 102 in the first phase 301 the shutter glasses switching cycle 600s may be larger than in the second phase 303 the shutter glasses switching cycle 600s ,

The first phase 301 the shutter glasses switching cycle 701 may comprise: a first subphase 301 in which the left glass 302l and the right glass 302r the shutter glasses 102 are in a transparent state.

The first phase 301 the shutter glasses switching cycle 701 may further comprise: a second subphase 301b in which the left glass 302l and the right glass 302r the shutter glasses 102 are in an opaque state.

The first subphase 301 For example, it can be timed to the second subphase 301b adjacent, for example, when the left glass 302l and the right glass 302r the shutter glasses 102 be switched simultaneously.

The switching of the left lens 302l and the right lens 302r of the shutter glasses 102 can be done by means of the control signal 304s. For example, the control signal 304s having the first command, which is the left glass 302l and the right glass 302r the shutter glasses 102 at the same time in the transparent state brings. Alternatively or additionally, for example, the control signal 304s have the second command which the left glass 302l and the right glass 302r of the shutter glasses 102 at the same time in the opaque state brings.

For example, the switching to the first subphase 301a and / or into the subphase 301 with more than the pulse rate of the image information, for example, with at least twice (eg, three times, four times, five times or more) the pulse rate.

Clearly, a flicker can be reduced and / or prevented by means of the subphase (s).

In other words, the third subphase 301c a switch between the first subphase 301 and the second sub-phase 301b, ie, representing a transient state between them.

The first subphase 301 and the second subphase 301b for example, a temporal Distance apart, for example, when the left glass 302l and the right glass 302r of the shutter glasses 102 be switched one after the other. Temporarily between the first subphase 301 and the second subphase 301b can the third subphase 301c be arranged. A duration of the third subphase 301c may be less than a duration of the first subphase 301 and / or as a duration of the second subphase 301b , eg less than 10% of the duration of the first subphase 301 and / or the second subphase 301b ,

For example, the control signal 304s have a first command which the left glass 302l and the right glass 302r of the shutter glasses 102 one after the other into the transparent state. Alternatively or additionally, for example, the control signal 304s have a second command which the left glass 302l and the right glass 302r the shutter glasses 102 one after the other into opaque state.

The second subcommand may be configured to bring the left lens 302l into the opaque state. The additional second partial command can be set up, the right-hand glass 302r to bring in the opaque state.

Alternatively, the time-shifted switching of the two glasses 302r , 302l due to a staggered control of the two glasses 302r , 302l, for example when a power source of the shutter glasses 102 not enough voltage to simultaneously switch both glasses 302r , 302l supplies.

The control can be understood as an intended influencing of a system. In this case, the state of the system can be changed according to a specification, e.g. by changing an actuator of the system. Rules can be understood as taxes, with a change of state of the system is additionally counteracted by disturbances. Clearly, the controller may have a forward-looking control path and thus illustratively implement a flow control, which converts an input variable into an output variable. The control path can also be part of a control loop, so that a control is implemented. The control, in contrast to the pure forward control, has a continuous influence of the output on the input (also referred to as reference) caused by the control loop (feedback), e.g. by means of the actuator. In other words, as an alternative or in addition to the control, a regulation can be used or, alternatively or in addition to the control, a regulation can take place.

To the increase of the degree of disturbance 1300a Optionally counteract the open time of the shutter glasses 102 be reduced, for example, in the same degree, which, for example, keeps the degree of interference constant. To the increase in the degree of interference 1300a counteract, may alternatively or additionally, the radiation power per radiation pulse 204 be enlarged.

The open time can be reduced, for example, by the frequency and / or duration of the second subphase 301b per first phase 301 is increased and / or by the duration of the first phase 301 is reduced.

The method may optionally include in 1305 (eg, in a second mode of operation of the controller): increasing the contrast of the filtered image information, eg, by increasing the radiant power per radiation pulse.

The shutter glasses switching cycle may include: a first phase in which the left lens and the right lens of the shutter glasses are in a transparent state; and a second phase in which the left lens and the right lens of the eyeglasses are in an opaque state.

The switching between the transparent state and the opaque state can be cyclic, i. repeated, e.g. as long as the image information is displayed, e.g. according to the shutter glasses switching cycle.

The procedure 1800 can be performed by means of a control device according to various embodiments. The control device may be integrated in a display device, for example in a mobile device or in a standalone device, and / or in an image source adapter.

20 illustrates a method 2000 according to various embodiments in a schematic flow diagram.

The procedure 2000 can be used to control a shutter glasses 102 be furnished, which has two switchable glasses.

The procedure 2000 can have in 2001: Determining or providing a temporal characteristic of a pulsed displayed image information, eg their pulse characteristics (eg their PWM), eg their pulse duration, pulse rate, pulse amplitude and / or their pulse energy.

For example, providing the information may include generating a pulse characteristic information representing a pulse characteristic according to which a displayed image information is pulsed. In accordance with the pulse characteristic information, for example, a radiation source control signal can subsequently be generated by means of which an image source (for example its radiation source) is to be controlled. By way of example, the determining may comprise: detecting a display duration of the image information per individual image and / or a refresh rate of the image information. The detection can be done, for example, optically and / or by a radiation source control signal of the image source is read out. For example, it can be tracked when displaying one or each Frame of the image information takes place, how long the display of the or each frame of the image information takes place and / or with which temporal distance the display of successive individual images of the image information.

The temporal characteristic may represent a display cycle comprising: a first phase in which a (e.g., radiometric or electrical) luminosity magnitude of the pulsed displayed image information satisfies a predetermined criterion; and a second phase in which the luminosity size does not meet the criterion. The first phase can have, for example, a radiation pulse, by means of which the image information is displayed. The second phase may, for example, be arranged in time between two successive radiation pulses of the image information and / or be free from a radiation pulse of the image information.

The temporal characteristic may represent a plurality of frames or pulses (e.g., radiation pulses) of the pulsed displayed image information. The temporal characteristic, e.g. the pulse characteristic may be a luminous intensity quantity averaged over several individual frames or radiation pulses of the image information, e.g. averaged over more than 60 individual images or radiation pulses. This can result in a reliable value.

The procedure 2000 may further comprise in 2003: providing a control signal for the shutter glasses in accordance with the temporal characteristic of the image information, eg its display cycle. The control signal may be arranged to bring a left lens and a right lens of the shutter glasses in a transparent state in the first phase of the display cycle; and in the second phase of the display cycle, to bring the left lens and the right lens of the shutter glasses into an opaque state.

For example, the shutter glasses switching cycle may be synchronized with the temporal characteristic of the image information, e.g. the display cycle, his. For example, the first phase of the shutter glasses switching cycle and the first phase of the display cycle may be simultaneous or at least partially overlapping in time (i.e., partially or completely). Alternatively or additionally, the second phase of the shutter glasses switching cycle and the second phase of the display cycle may be simultaneous or at least partially overlapping in time (i.e., partially or completely).

The procedure 2000 can be performed by means of a control device according to various embodiments. The control device may be integrated in a display device, for example in a mobile device or in a standalone device, and / or in an image source adapter.

Alternatively or additionally, the method 2000 be performed by a computer program product, for example by the processor of a mobile device (eg a mobile phone, a tablet, a camera, a laptop, or a navigation device) executes the computer program product. Alternatively or additionally, the computer program product can be stored on a nonvolatile data carrier.

21 illustrates a method 2100 according to various embodiments in a schematic view of the displayed image information to illustrate the operation of various embodiments compared to the conventional view (top) for viewing according to various embodiments (below).

The procedure 2100 may include in 2101: displaying image information by means of a pulsed image source. The visibility of the displayed image information 204 can be, for example, from interfering radiation 206 . 208 (eg stray light 206, 208) are affected (see also 2A to 2C ). The displayed image information may be in a range, for example 203b from the interference radiation 206 . 208 be outshone. The overexposed area 203b can be optional of an additional area 203c be surrounded, in which the contrast 205k the displayed image information is reduced.

The procedure 2100 may further include in 2103: filtering out 222 the interfering radiation 206 . 208 by means of a shutter glasses 102 , By filtering out 222 can the extent of the area 203b and / or the extent of the additional area 203c be reduced.

The image information may comprise one or more images, eg, a synthetic image. For example, method 2100 in 2101: displaying stereoscopic image information by means of the image source, eg by means of a screen (also referred to as a monitor). Alternatively or additionally, a monoscopic image information can be displayed by means of the image source.

Optionally, the procedure 2100 in 2103: synchronizing the shutter glasses with the pulsed operation of the image source. For example, the synchronization may include associating with each monoscopic image of the image information a shutter glasses switching cycle and / or synchronizing them with one another.

Optionally, one or each partial image of the stereoscopic image information can be treated as a monoscopic image. In other words, the or each field of the stereoscopic image information with exactly one Shutterbrille switching cycle be assigned and / or these can be synchronized with each other.

For example, monoscopic image information may be formed from the stereoscopic image information, e.g. by hiding (not displaying) a partial image of each stereoscopic image of the image information. The displayed partial image of each stereoscopic image of the image information may include or be formed from the monoscopic image (also referred to as a payload image). If the shutter glasses are operated in a conventional 3D mode, the observer can thus view the displayed useful image with one eye, while the latter sees a black image (black image) with the other eye. The spurious radiation (e.g., ambient light, e.g., its reflection or backlight) may be dimmed by half at 2103 because the shutter glasses 102 will open the left glass 302l only halfway in time. The utility image, however, can only be slightly darker, since the left glass of the shutter glasses (in the period in which this is displayed) is open.

Optionally, the procedure 2100 in 2103: reducing the time (emission time of the display cycle) in which the image source emits radiation. For example, the pulse duration of the pulsed displayed image information can be reduced, for example by means of PWM. Alternatively or additionally, the pulse frequency of the pulsed displayed image information can be reduced. The reduction of the time can take place, for example, in a first operating mode of the control device. To reduce the time can (eg in the first operating mode) influence on the image source, for example by means of the additional control signal.

For example, the time (e.g., the emission phase of the display cycle) in which the image source emits radiation may be less than 10% of the display cycle. Alternatively or additionally, the time (the dark phase of the display cycle) in which the image source emits no radiation may be more than 90% of the display cycle. Thus, more filtering out of the spurious radiation (e.g., stray light) can be achieved (e.g., less than half).

For example, during the time the black image is displayed, the backlight (e.g., its LEDs) of the image source may be turned off. With the same contrast experienced, only half of the energy can clearly be consumed. The first mode of operation can vividly reduce energy consumption, e.g. at least half. Thus, the energy consumption for displaying the image information can be reduced.

Optionally, the procedure 2100 in 2103: increasing the radiant power per radiation pulse of the pulsed displayed image information, eg, alternatively or additionally to reducing the time in which the image source emits radiation. The magnification of the radiation power can take place, for example, in a second operating mode of the control device. To increase the radiation power can (eg in the second operating mode) influence on the image source, for example by means of the additional control signal.

For example, the method 2100 in 2103: increasing the radiation power per radiation pulse of the pulsed displayed image information and at the same time reducing the time in which the image source emits radiation (pulse duration) at constant radiation energy per radiation pulse, eg by means of PWM. For example, in 2103 the radiation power per radiation pulse can be doubled and / or the time in which the image source emits radiation can be halved. This can be achieved that can be dispensed with a change in the image source. By way of example, the filtering out of the interference radiation can take place by means of a conventional image source. For example, the backlight (eg, a conventional LED panel) can be operated in the luminous phases with twice the power without destroying it, as clearly the emitted radiation energy per radiation pulse remains the same.

Alternatively, the method 2100 in 2103: increasing the radiation energy per radiation pulse of the pulsed displayed image information. Clearly, the image source can then be operated in (unfiltered operation) with half the power. For example, a more powerful backlight may be used, for example if a conventional backlight can not provide the increased radiant energy per radiation pulse.

22A illustrates a method 2200a according to various embodiments in a schematic side view or cross-sectional view.

The procedure 2200a may include: emitting pulsed electromagnetic radiation 204 (also referred to as radiation pulses 204) according to image information in a receiver area 151 , The radiation pulses 204 For example, they may have electromagnetic radiation in the range of visible light, eg red light, blue light and / or green light. For example, the emission of pulsed electromagnetic radiation 204 according to the image information, radiation pulses 204 to emit, which transmit the image information, eg in a display direction 111 (eg in the direction of the receiver area 151). Optionally, in the receiver area 151 a receiver 113 may be arranged. The receiver may, for example, have a sensor, eg an organic sensor (eg an eye) or an inorganic sensor (eg an optoelectronic sensor). For example, the recipient may be a human viewer.

The emitting of the pulsed electromagnetic radiation 204 may include, for example: pulsed displaying of image information on an emitting surface 202 , eg by means of an electronically controlled image source. The electronically controlled image source may have a screen which shows the emission area 202 from which the pulsed electromagnetic radiation 204 is emitted. Alternatively, the electronically controlled image source may comprise a projector. The projector may be configured, for example, pulsed electromagnetic radiation on the emission surface 202 (eg, a projection surface), from which it is reflected.

The procedure 2200a may further comprise: filtering out of interference 206 . 208 (eg reflection 206 and / or backlight 208 ) from the electromagnetic radiation 246u (also as unfiltered radiation 246u designated), which in the direction of the receiver area 151 is emitted by means of a shutter glasses 102 , In other words, the method may include: separating the interference radiation 206 . 208 from the image information (or the pulsed radiation 204 ).

This can be the shutter glasses 102 between the emitting surface 202 and the receiver region 151 be arranged or become. The shutter glasses 102 may comprise two electronically switchable glasses, which are for example arranged to be switched between an opaque state and a transparent state. The electromagnetic radiation passing through the shutter glasses 102 passes through, can as filtered radiation 246g be designated.

Clearly, the unfiltered radiation 246u the radiation pulses 204 and, depending on the environment, in addition to the interference 206 . 208 (eg backlight 208 ), which eg from behind the emission surface 202 can come. Using the shutter glasses 102 can at least part of the interference 206 . 208 be filtered out. For example, in the time interval, a ratio of interference radiation 206, 208 to radiation pulses 204 (Eg their radiation power) can be reduced by means of filtering out. In other words, a ratio of spurious radiation 206 . 208 to radiation pulses 204 (eg their radiation power) on the unfiltered radiation 246u be larger than the filtered radiation 246g ,

The filtering out of the interference radiation 206 . 208 using the shutter glasses 102 may, for example, include: switching the two glasses of shutter glasses to the transparent state in a time interval in which a (eg radiometric or electrical) luminosity magnitude of a pulsed displayed image information satisfies a predetermined criterion; and (eg, before and / or after) switching the two lenses of the shutter glasses into an opaque state.

The switching between the transparent state and the opaque state can be cyclic, i. repeated, e.g. as long as the image information is displayed and / or in accordance with the shutter glasses switching cycle.

Illustratively, for example, glare from backlighting (e.g., viewing a digital camera display) may be reduced. In other words, according to various embodiments, a reflection and / or backlight can be reduced.

By filtering out the interference radiation 206 . 208 can be achieved that the pupil is less reduced. For example, in contrast to normal sunglasses, the display can be darkened less.

22B and 22C each illustrates a display device 2200b . 2200c according to various embodiments in a schematic perspective view.

The display device 2200b can be a mobile device 2206 . 2208 for recording or displaying image information or be formed therefrom, such as a digital camera 2206 (eg single-frame camera) or a movie camera 2208 (eg video camera). The mobile device can be an image source 1512 which may be arranged, for example, as the image source 1400a or the image source 1400b ,

Furthermore, the display device 2200b the control device 1502 exhibit. The control device 1502 For example, it may be integrated into the mobile device, for example by means of a physical communication connection.

Alternatively, the control device 1502 externally from the display device 2200b be provided or, for example by means of the image source adapter, which may be attached to the mobile device, for example, or by means of a shutter glasses 102 ,

The mobile device may optionally include or be formed from an accumulator which supplies it with electrical energy.

Especially with a mobile device 2206 . 2208 For recording and displaying image information, according to various embodiments, an improvement can be achieved since, in contrast to a smartphone or tablet, it can not be arbitrarily positioned, but rather is aimed at the object to be recorded. Therefore, applying the method to the image source (eg, display) of an image and video camera can improve the perceptibility of the displayed image information.

Illustratively, a smartphone and / or tablet in use may be at least partially protected from ambient light, for example by being turned away from the source of disturbance light (e.g., the sun); Positioned in the shadow of the viewer or an object (wall, table, etc.) and / or by the viewer moves together with the device on / in a shady place / room. These possibilities are largely eliminated when using a camera, as it must be kept in a specific direction from a specific location in order to achieve the desired recording result.

23 illustrates a shutter glasses in a shutter glasses switching cycle 2300 according to various embodiments in a schematic circuit diagram.

The shutter glasses switching cycle 2300 may include: a first phase 301 in which a left glass area 302l and a right glass area 302r the shutter glasses 102 in a transparent state, the left glass area 302l and the right glass area 302r Are part of the same spectacle lens. Optionally, between the right glass area 302r and the left glass portion 302l a recess 2302 be arranged for receiving the nose of a user.

The shutter glasses switching cycle 2300 may further comprise: a second phase 303 in which the left glass area 302l and the right glass area 302r the shutter glasses 102 are in an opaque state.

In the transparent state, a transparency of the lens of the shutter glasses 102 which is the left glass area 302l and the right glass area 302r is greater than in the opaque state, eg, about twice or more, eg, about three times or more, eg, about four times or more, eg, about five times or more, eg, about ten times or more ,

The first phase 301 For example, it may be time for the second phase 303 adjacent, for example, when the lens 302l, 302r the shutter glasses 102 is switched.

The switching of the spectacle lens 302l, 302r of the shutter eyeglasses 102 can be effected by means of the control signal 304s respectively. Clearly, the filtering out 222 by means of the control signal 304s (also as a filter control signal 304s referred to), for example, controlled and / or regulated. The control signal 304s can vividly sync the shutter glasses 102 effect with the image information.

For example, the control signal 304s have a first command, which the eyeglass lens 302l, 302r the shutter glasses 102 brings in the transparent state. Alternatively or additionally, the control signal 304s have a second command, which the eyeglass lens 302l, 302r the shutter glasses 102 brings in the opaque state.

For example, switching to the first phase 301 and / or the second phase 303 take place with the pulse rate of the image information, eg according to their PWM. Alternatively or additionally, the switching between the first phase 301 and the second phase 303 with twice the pulse rate of the image information.

Optionally, a duration of the first phase 301 be smaller than a duration of the second phase 303 , Alternatively or additionally, the shutter glasses switching cycle 2300 exactly a first phase 301 and exactly a second phase 303 exhibit.

According to various embodiments, the ambient light is reduced by the ratio n / m by means of the provided control device (eg internally in a shutter glasses or externally to it), where n is the temporal portion of the first phase (open shutter glasses) and m is the temporal portion of the second phase ( closed shutter glasses) on the shutter glasses switching cycle. According to various embodiments, the background illumination or active illumination of an image source (eg a display) with the (two-sided) control of a shutter glasses are synchronized in time so that the shutter glasses in the first phase (open) is only when the lighting of the Image source (eg display lighting) is turned on and / or the illumination of the image source is only turned on (ie light emitted) when the shutter glasses in the first phase. Thus, with the same energy use, a higher contrast between useful signal and stray light can be achieved. Illustratively, the two spectacle lenses and / or the common spectacle lens can, for example, only be transparent if a useful signal is present (eg the display is lit). At 50% clock or less (n / m = 0.5 or less), the entire luminous intensity of the useful signal can thus reach the eye (if the shutter glasses are exactly transparent in this time interval, eg only at this time interval) while the ambient light reaches the eye only to 50% or less.

24 illustrates a conventional shutter glasses 2400 for 3D visualization. The shutter glasses 2400 can have two LC lenses.

The shutter glasses 2400 can sync a signal from a screen 2401 which is set up while the left-eye image is displayed on the screen, close the right-hand lens LC by applying an electric voltage to it, and open the left-hand lens LC by turning it off , ie the shutter glasses 2400 in a state representing the left image 2400a to move. Analog can be the synchronization signal 2401 be set up while the right-eye image is displayed on the screen to close the left lens LC by applying an electric voltage to it, and to open the right lens LC by turning it off, ie Shutterbrille 2400 in a state representing the right image 2400b to move. In other words, the left and right lenses can be driven in push-pull, ie open and closed. If the conventional shutter glasses 2400 is switched off or no synchronization signal 2401 receives, both lenses are open because the two LC lenses are de-energized, ie the shutter glasses 2400 is in a rest state 2400c ,
