Definitions
- Applicant's WO2015 / 121398 describes a screen which can be operated in two modes of operation for a free and a restricted viewing mode.
- scattering particles in the volume of the corresponding light guide essential for the switching of the modes.
- These scattering particles are made of polymer and may under certain circumstances, especially at higher concentrations, lead to scattering effects that reduce the protective effect in the protected operating mode.
- Other methods and arrangements for the fulfillment of similar purposes are known, wherein the achievement of the limited viewing mode, especially in dark surroundings, is often limi advantage, as a residual light still penetrates into the actually shielded viewing angle. Then, if the ambient light is low and thus the viewer pupil wide open, so often residual information can be taken true even from the screened angles of view.
- the process should be as simple as possible to implement.
- a method for manipulating image data for a screen which can be operated in at least two operating modes B1 for a clear view mode and B2 for a restricted viewing mode, comprising the following steps:
- ii. is implemented dynamically in a drive unit of the screen (1), and iii. exclusively during the period in which the signal S is set is performed,
- Output image data is understood here to mean the data that is displayed on the screen when the signal S is not set, i. the unmanipulated data.
- the term "brightness” in the above context is understood to mean the brightness impressed on the image data, but not the overall brightness of the image screen that can be set using light sources.
- the Ausschal th of the engine in a vehicle In addition to the termination condition of switching off the mode B2 or a change to the mode B1 and other termination criteria are conceivable, for example, the Ausschal th of the engine in a vehicle.
- step c) can in extreme cases also mean the complete switching off of the screen, wherein the associated total invisibility of an image would alternatively be achieved by manipulating a Michelson contrast of 0%.
- Edre dend is the said manipulation - which can also be understood in the sense of a correction for compliance with specifications in operating mode B2 - in the free viewing mode B1 is not active.
- recurrent monitoring is meant that the same at defined time intervals, e.g. every 0.2 seconds, takes place.
- the screen which can be operated in at least two operating modes B1 for a free viewing mode and B2 for a restricted viewing mode, is based for example on an LCD or OLED panel.
- the said poorer visual recognizability of the image data is produced by a reduced contrast compared to the original image data, a lower brightness, a lower resolution, a reduced color space and / or static or dynamic transitions. These changes can go as far as a pure black and white representation.
- blending of checkerboard patterns or other regular or irregular patterns may be considered as blending to reduce visual cognition.
- a high-pass filtering of the relevant image data in question in order to avoid - usually rather easily recognizable - low frequencies in the image.
- a dynamic adaptation also includes that the nature of the influences on the displayed image contents can be or should preferably be. For example, the representation of a bright area would not necessarily undergo a change in contrast reduction, while in such a case, the reduction in brightness is clearly helpful in enhancing privacy. Corresponding regulations are implemented in said control unit.
- the method according to the invention acquires a special quality if the said poorer recognizability of the image data is time-modulated and preferably increases with the longer time during which the signal S is set, wherein optionally after exceeding a specifiable minimum time t during which the Signal S is set, the screen consume completely switched off and / or the image display on the screen is stopped or interrupted.
- the monitoring of the eye position with little delay - ie delays of less than 0.2 s, ie in real time - is preferably realized by an eye tracking system, wherein at least the viewing angle of both eyes in the horizontal and / or vertical direction for the angular range alpha and Optionally, the viewer's head position relative to the screen should be taken into account to determine whether the signal S should be set or not.
- Suitable eye tracking systems are known in the art and can be practiced by those skilled in the art.
- the terms "horizontal” and "vertical” are for umbrellas whose surface is not aligned parallel to the earth's surface, usually absolute to understand, ie parallel or perpendicular to the earth's surface. For horizontal screens, but also for most in-vehicle monitors, the horizontal direction corresponds to the longer side and the vertical direction to the shorter side of a rectangular screen when aligned in landscape mode.
- the inventive method is advantageously used in a vehicle, wherein the viewer corresponds to the driver.
- This circumstance is especially in darker environmental conditions, e.g. at night, a great advantage, because then the pupil of the driver is far and even very low residual light, which is usually present in the optical / opto-electronic / electronic switching of the viewing mode B2 on the screen from actually locked viewing angles, for the driver remains at least still noticeable.
- the eye position is monitored only for viewers, which are in Winkelberei chen alpha horizontally between 90 degrees to greater than 20, 25 or 30 degrees of a means perpendicular to the image surface of the screen. In a car this would correspond to the driver's eye po- sition, even if the driver leaned slightly towards the passenger.
- the angle range alpha can then be considered accordingly - depending on whether the vehicle is a left-hand or a right-hand drive - to the left or right of the mid-perpendicular considered.
- the eye position is monitored only for one - or more - Be trachter, which are at a maximum distance of 1, 2 m from a center with the image surface of the screen.
- a maximum distance 1, 2 m from a center with the image surface of the screen.
- Smaller values such as 1 m or 0.8 m are also conceivable for the aforementioned maximum distance.
- Another advantageous embodiment turns out to be, in which during the time within which the signal S is set, in the image data one or more Textmeldun gene and / or one or more symbols are blended.
- text messages such as "image manipulation due to driver distraction” or "image manipulation due to friction distraction” make sense.
- the co-driver is also indirectly animated to ask the driver or viewer to look away from the screen. If the signal S is then no longer set because the driver, ie the observer, is away, the above-described crossfading with text messages or symbols will be canceled immediately and of course - if implemented - all manipulations of the image data according to the invention will be canceled and the output image data will again be displayed shown.
- the said cancellation of manipulations of the image data may optionally be performed over a period of time, e.g. 5 seconds, in order to make the viewing experience pleasant for the direct observer whose eye position is not being followed.
- FIG. 1 shows a schematic diagram of a screen in the mode B1 for a free viewing mode
- FIG. 2 is a schematic diagram of a screen in the mode B2 for a limited view mode
- FIG. 1 shows a schematic diagram of a screen in the mode B1 for a free viewing mode.
- FIG. 2 shows a schematic diagram of a screen in the B2 mode for a restricted viewing mode.
- the drawings 1 and 2 presented here are described as state of the art as local drawings FIGS. 3 and 4 in their design and mode of operation, which should not be repeated here for redundancy reasons.
- the screen 1 can also be other configurations which enable the two operating modes B1 and B2.
- FIG. 3 shows a schematic representation of the application of the invention in a vehicle, wherein the image manipulation according to the invention is not active because the signal S is not set.
- FIG. 4 shows a schematic representation of the application of the invention in a vehicle, wherein the image manipulation according to the invention is active because the signal S is set.
- the inventive method for manipulating image data for a screen 1, which can be operated in at least two modes B1 for a free viewing mode and B2 for a limited viewing mode, and which is configured, for example, according to the teaching of WO2015 / 121398 of the Applicant comprises, as described above described the following steps: a) switching on operating mode B2,
- ii. is implemented dynamically in a drive unit of the screen 1, and iii. exclusively during the period in which the signal S is set is performed,
- the said manipulation in the free viewing mode B1 is not active, i. it is not done in this mode.
- a permanent or recurrent monitoring of the eye position of an observer 2 takes place in a predetermined angle range alpha.
- FIG. 3 shows that the observer 2 looks over the steering wheel 4 in a vehicle.
- the signal S is not set and the manipulation according to the invention in step c) is not active.
- the passenger so the viewer 3, can now undisturbed in the protected preparer dus B2, the contents of the screen 1, for example, web pages or entertainment program, such as digital TV, watch.
- Figure 4 shows the schematic representation of the application of the invention in egg nem vehicle, wherein the image manipulation according to the invention according to step e) is active, because the signal S is set.
- the viewer 2 ie the driver, looks at the screen 1, which is detected by monitoring the eye position. Accordingly, the signal S is set.
- the viewer 3 also looks at the screen 1.
- the manipulations of the image data according to the invention are active, which is indicated by the dotted area of the screen 1.
- the manipulations are of course also visible, but he can usually easily recognize the image due to the aligned him restricting th viewing angle in the viewing mode B2 of the screen 1 the image.
- the respective manipulation (s) is carried out in such a way that a poorer visual recognizability of the image data is generated, whereby the quality of the restricted viewing mode B2 is enhanced.
- the said poorer visual recognizability of the image data is produced by a reduced contrast and a lower brightness compared to the original image data.
- the contrast reduction can be e.g. be implemented by switching on a corresponding image data filter, as well as the reduced brightness.
- the influence on the contrast and the brightness are dynamically set in the drive unit of the screen 1, which is for example designed as an electronic controller board.
- This implementation then refers to both still images and moving images and can also be varied over time.
- the method according to the invention acquires a special quality if the said poorer perceptibility of the image data is time-modulated and preferably increases with a longer time, during which the signal S is set.
- the brightness and the contrast can thus be reduced further and further, in particular with increasing time during which the signal S is set, in order to bring the viewing interest to the viewer 2 without the viewer 3, thus the passenger. by switching off the picture completely withdraw.
- the screen 1 is completely turned off and / or the image display on the screen 1 stopped or interrupted.
- the above-to-be-considered perspective of both eyes of the observer 2, so the driver, in horizontal and / or vertical direction can be determined by the geometry in a given vehicle for the Eyebox - it is a empirically determined, three-dimensional space in which the eyes of the viewer or the viewer with the highest probability, usually more than 95%, reside - the driver's perspective on the screen 1 are determined.
- the Sig nal S should not be set if the viewer 2 clearly does not look at the screen 1, so even if he looks over the screen 1, for example.
- the eye position is monitored only for eyes of the observer 2, which are located in angle ranges alpha horizontally between 90 degrees to greater than 20, 25 or 30 degrees from the mid-perpendicular of the image area of the screen 1. That would correspond to the driver in a car, even if he - belted - something leaning towards the passenger, the screen 1 is here in the horizontal approximately in the middle in front of the passenger, so the viewer 3, is adopted.
- the angle range alpha can then be considered accordingly - depending on whether the vehicle is a left- or right-hand drive - to the left or right of the mid-perpendicular considered.
- Suitable eye tracking systems are known in the art and can be easily implemented by the skilled man.
- This circumstance is especially at darker confusingbedingun gene, so e.g. at night, a great advantage, because then the pupil of the driver is far and even very low residual light, which is usually present in the optical / opto-electronic switching of the viewing mode B2 on the screen 1 from actually locked viewing angles for the Driver remains at least still noticeable.
- the eye position is monitored only for one (or more) Be trachter 2, which are located at a maximum distance of 1, 2 m from the center of the image surface of the screen 1. This will then be used e.g. in a vehicle only the driver and not a sitting in the back seat passenger as a viewer 2 einbe pulled. Smaller values such as 1 m or 0.8 m are also conceivable for the aforementioned maximum distance.
- the eye positions of several observers 2 can be considered for the inventive method, and it is sufficient for the setting of the signal S when only a viewer looks at the screen 1.
- Another advantageous embodiment is that in which, during the time within which the signal S is set, one or more text messages and / or one or more symbols are superimposed in the image data.
- text messages such as "image manipulation due to driver distraction” or "image manipulation due to friction distraction” make sense.
- the invention described above achieves the stated object: By means of the method according to the invention for manipulating image data for a screen, it is possible to significantly enhance the secure display of information in the restricted viewing mode.
- the method is furthermore easy to implement.
