Description

[Technical field]

[0001] (Related Application Description) This application claims priority from European Patent Application No. 23194681.5 (DAS Code: 2712), filed August 31, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a method for resolution-optimized control of an illumination module for an automotive lamp, the illumination module being configured to emit a segmented light distribution having individually controllable light segments, the illumination module comprising a deflection unit, by means of which the native resolution of the illumination module can be visually increased by at least temporary light beam deflection by means of the deflection unit. [Background technology]

[0003] From the prior art, methods have become known for controlling illumination modules, which allow for a time-variable change of the light emission of individual segments of the light distribution. In this case, the resolution is usually limited by the resolution of the corresponding illumination module. In order to achieve an increased visual resolution, methods have become known in which the inherent resolution of the illumination module can be visually increased by at least a temporary light beam change using a deflection unit.

[0004] The following patent document 1 (US2020 / 0363707 A1) shows an optical device. This publication shows that the resolution of the optical device can be increased in the visual overlap of two different images. For this purpose, two different images are calculated from an input image. These two different images are output in time succession and with physically separate synchronization signals from those for the deflection units. This synchronization is obviously very complex and resource-intensive. [Prior art documents] [Patent documents]

(Form 13) 1. An illumination module for an automotive lamp, comprising: The illumination module is configured to emit a segmented light distribution, the illumination module includes a deflection unit, and by using the deflection unit, a visually perceptible resolution of the light distribution generated by the illumination module can be increased compared to an inherent resolution of the illumination module, and the illumination module is configured to be controlled at least according to step c) of the method according to any one of aspects 1 to 12. (Form 14) In the irradiation module according to aspect 13, the irradiation module further includes a memory unit and a module control unit; the storage unit is configured to store at least one first low-resolution image and at least one second low-resolution image; the module control unit is configured to retrieve the first low-resolution image and the second low-resolution image from the storage unit and provide a light control signal to a light source, whereby either the first low-resolution image or the second low-resolution image is emitted by the illumination module; It is further preferable that the module control unit is configured to control the deflection unit so that, when the first low-resolution image is emitted by the irradiation module, the deflection unit repeatedly deflects the first low-resolution image, and that the module control unit is further configured to control the deflection unit so that, when the second low-resolution image is emitted by the irradiation module, the deflection unit does not repeatedly deflect the second low-resolution image. (Form 15) A vehicle equipped with an illumination module according to aspect 13 or 14, wherein the vehicle and / or the illumination module is configured to at least partially carry out a method according to any one of aspects 1 to 12.

[0011] In this case, the expression "resolution" is understood as the sum of the light segments in the respective image. The "native resolution" is therefore the resolution given by the sum of the individually controllable light segments for light emission. For example, if the light segments are arranged in two rows and two columns and are individually controllable, this corresponds to a native resolution of 2x2, where each individually controllable light segment can also be called an illumination pixel. The illumination module (light-emitting module) preferably has a native resolution of at least 2x2. Particularly preferred is a high-resolution illumination module for automotive lighting.

[0012] Within the framework of this patent application, the term "unit", either alone or in compound terms such as "projection unit", "deflection unit", "module control unit" or "storage unit", should not necessarily be understood as an individual element, i.e. the term may include a plurality of elements, groups, components, elements or combinations thereof.

[0013] By at least a temporary or repeated deflection of the light beam by means of a deflection unit, it is possible to increase the resolution perceived by the human eye compared to the intrinsic resolution, i.e. the visual overlap resulting from the at least a temporary deflection of the light beam is obtained due to the inertia of the human eye (persistence of vision: persistence of vision).

[0014] By (temporary or) repetitive deflection is meant a deflection that results in the aforementioned visual overlap of the first low-resolution image with itself during a first time range. The magnitude (degree) of overlap of the first low-resolution image with itself can be described based on at least one deflection parameter.

[0015] The target image can have a target light distribution.

[0016] For the question of image similarity, the skilled person knows suitable algorithms for the evaluation. For example, mutual information (see, for example, the keyword "Mutual Information") or structural similarity (see, for example, the keyword SSIM (structural similarity index measure)) can be used here. Extensive information about these concepts is also available online in the online encyclopedia "Wikipedia".

[0017] In particular, the deflection unit may be configured to deflect the first low-resolution image repeatedly within a first time range with a frequency of at least 30 Hz, typically between 30 Hz and 160 Hz.

[0018] Furthermore, the illumination module can have individually controllable light segments, in which case the segmentation of the light distribution is achieved by the individually controllable light segments, which are arranged next to each other almost without gaps in a matrix having a resolution of at least 2 rows and 2 columns.

[0019] Optionally, the maximum deflection performed by the deflection unit may be configured such that the deflected state has a vertical offset as well as a horizontal offset of substantially half the light segment width compared to the undeflected reference state, such that at the maximum amplitude of deflection, each deflected light segment, except for the edge light segments, visually overlaps substantially four undeflected light segments.

[0020] In this case, the light segments, except for the edge light segments, are visually overlapped spatially by 25 percent in the repeated deflection. The perceived resolution can thus be approximately four times the intrinsic resolution. An edge light segment is understood to be a light segment that is not surrounded on all sides by other light segments, but has no adjacent light segments on at least one side. The edge light segment thus represents the edge region of the image to be projected.

[0021] The amount of overlap can in any case be described based on at least one deflection parameter.

[0022] In particular, the deflection unit can have a neutral position, which may, but does not have to, be different from the zero position. In this neutral position, the deflection unit does not bring about a repeated deflection of the passing light. If the deflection unit is not needed or has to be switched off, the emission of the first low-resolution image is still guaranteed.

[0023] The first transformation rule may include at least an approximate solution of a system of linear equations (simultaneous linear equations), which includes a set of linear equations that contain information of the target image relative to the first low-resolution image within at least partial overlap with itself [see paragraph 68].

[0024] This preferred configuration of the first transformation rule as an at least approximate solution preferably involves an iterative solution of the system of linear equations.

[0025] A linear equation can describe the relationship between each portion of the first low resolution image within at least partial overlap with itself and each portion of the target image.

[0026] Said information of the target image relative to the first low resolution image within at least partial overlap with itself may further include at least one deflection parameter.

[0027] For reasons of efficiency, the first conversion rule can be executed by an external calculation unit, and preferably the first low-resolution image is stored (stored) in a memory unit of the projection module so as to be retrievable.Moreover, preferably, in step b), the target image received according to step a) can be additionally converted into a second low-resolution image based on a second conversion rule, and the second low-resolution image is selected such that it has the inherent resolution of the projection module, and furthermore, the second low-resolution image is selected such that it has an image impression more similar to the target image than the first low-resolution image, and in step c), within a second time range, the second low-resolution image is emitted by the projection module, and within the second time range, the second low-resolution image is not repeatedly deflected by the deflection unit.

[0028] That is to say, the deflection unit can be in a neutral position during the second time range.

[0029] In this case, the second transformation rule preferably includes a scaling method, in which the second low-resolution image is entirely transformed from the information of the target image. This scaling method can include reducing the resolution of the target image to the inherent resolution of the illumination module. This can be, for example, a "downsampling" method. Furthermore, this can be, for example, a block processing method, in which the values ​​of all light segments of the second low-resolution image are calculated, for example, from the block-wise average value formation of the target image.

[0030] The duration and / or start time of the first time range and the duration and / or start time of the second time range can be determined by at least one control parameter, where the at least one control parameter includes information about at least one of the following criteria: target light function, ambient temperature, ambient brightness, lighting module status, vehicle speed.

[0031] For efficiency reasons, the second transformation rule can be executed by an external computation unit.

[0032] In particular, the first low-resolution image converted according to step b) and the second low-resolution image converted according to step b) can be recallably saved (stored) in a storage unit in partial step b1), temporally prior to step c).

[0033] This storage unit may preferably be included in the illumination module.

[0034] Furthermore, the target image may have at least one continuous light and dark extension (light and dark boundary), and preferably the target image has multiple continuous light and dark extensions, which together form a single symbol.

[0035] The present invention further relates to an illumination module for an automotive lamp, the illumination module being configured to emit a segmented light distribution, the illumination module comprising a deflection unit, by means of which the visually perceptible resolution of the light distribution generated by the illumination module can be increased compared to the inherent resolution of the illumination module, the illumination module being configured to be controlled at least according to step c) of the above-mentioned method.

[0036] In this case, the irradiation module may further include a memory unit and a module control unit, and in this case, the memory unit is configured to save (store) at least one first low-resolution image and at least one second low-resolution image.

[0037] The module control unit is also configured to retrieve the first low-resolution image and the second low-resolution image from the storage unit and provide (output) a light control signal to the light source, whereby either the first low-resolution image or the second low-resolution image is emitted by the illumination module.

[0038] The module control unit is further configured to control the deflection unit such that, upon emission of the first low-resolution image by the illumination module, the deflection unit repeatedly deflects the first low-resolution image, and, in this case, the module control unit is further configured to control the deflection unit such that, upon emission of the second low-resolution image by the illumination module, the deflection unit does not repeatedly deflect the second low-resolution image.

[0039] The invention further relates to a motor vehicle equipped with such an illumination module, wherein the motor vehicle and / or the illumination module are adapted to at least partially perform the method described above.

[0040] All device configurations described in the method can also form part of an illumination module for a motor vehicle lamp, unless otherwise specified. And vice versa, all device configurations described in relation to an illumination module can also form part of the above-mentioned method. The illumination module can refer to both a signal lamp and an illumination module in a motor vehicle floodlight. The illumination module is preferably designed for use in a motor vehicle lamp, in particular for use in a signal light lamp or a motor vehicle floodlight. The illumination module can therefore be part of the above-mentioned device.

[0041] The invention will now be explained in more detail on the basis of illustrative and non-limiting embodiments, which are specifically illustrated in the drawings. [Brief description of the drawings]

[Diagram 5] 1 shows a comparison of a target image, a first low-resolution image, and a second low-resolution image within at least a temporary overlap with itself; [Figure 6] FIG. 1 shows a motor vehicle equipped with such an illumination module. EXAMPLES

[0043] Fig. 1 shows a schematic diagram of an illumination module 1 for an automotive lamp. The illumination module 1 is configured with individually controllable light segments to emit a segmented light distribution. The illumination module 1 comprises a module control unit 2, a storage unit 6, a light source 3, a deflection unit 4 and a projection unit 5. The storage unit 6 preferably comprises an electronic memory. Fig. 1 further shows an external calculation unit 7.

[0044] A wide variety of techniques are already known for generating segmented light distributions. These include, in particular, surface-based modulation with LEDs (light-emitting diodes) arranged in a matrix, surface-based light modulation with LCDs (liquid crystal displays) or surface-based light modulation with DLPs (digital light processing) or DMDs (digital mirror devices). Alternatively, light beam modulation techniques are also known, i.e. scanning systems that scan a light beam or light bundle over a given area with frequencies that are not perceptible to the human eye, thereby generating a freely variable light distribution. High-resolution illumination modules known today already allow resolutions with several thousand individually switchable and light-adjustable light segments, which are preferably arranged with an aspect ratio of 1:4, with the greater extension direction extending horizontally.

[0045] In this case, the concepts of horizontal and vertical directions relate to a specified mounting position of the irradiation module 1, and it is essential only that the horizontal and vertical directions represent directions perpendicular to each other.

[0046] The light source 3 shown in FIG. 1 can include several elements. For example, the light source 3 includes a light emitting element and a subsequent surface modulator (not shown), for example an LCD, DMD or DLP. Preferably, the light source 3 includes an array with at least two LEDs, each of which is individually controllable. Particularly preferably, the light source 3 includes an array with more than 1000 individually controllable LEDs arranged in an array with an aspect ratio of 1:4. Furthermore, the light source 3 can alternatively include a combination of a light emitting element, a collimator and a beam modulator, which scans the collimated light of the light emitting element in a scanning manner over a given area with a frequency that is not perceptible by the human eye. A light conversion element can be arranged in the area. The light source 3 can thereby be composed of several elements. Additional elements, such as optical lenses or reflectors, can be provided, which are not shown for the sake of clarity in the drawing.

[0047] What is essential is that a light source 3 emits a light bundle 30 which comprises at least two light segments in at least one plane perpendicular to the light propagation direction of the light bundle 30, which light segments can have different light intensities, and which thus correspond at least partially to the low-resolution images A, B in at least one plane perpendicular to the light propagation direction of the light bundle 30.

[0048] For this purpose the light source 3 can receive a light control signal 31 and can emit a light flux 30 depending on the light control signal 31. For this purpose the light control signal 31 can be at least partially representative of the light flux 30 emerging from the light source 3. The module control unit 2 can be configured to output the light control signal 31.

[0049] The light control signal 31 may be configured as at least part of an image signal that includes a low resolution image.

[0050] A light bundle 30 emitted by the light source 3 is projected by a projection unit 5 in a projection angle range P in front of the illumination module 1. A defined light distribution or a defined low-resolution image is thereby emitted by the illumination module 1. Correspondingly, a projection 50 of a defined low-resolution image is obtained in the projection angle range P in front of the illumination module 1. Such a projection unit 5 usually comprises a number of optical elements, in particular lenses. For the sake of clarity of the drawings, these optical elements are not shown.

[0051] The projection angle range P is determined by the aperture of the projection unit 5. It therefore corresponds to the maximum possible radiation cone of the projection unit 5. Such a radiation cone relates to a cone in the mathematical sense, which can also include all its sub-variations, such as for example a pyramid or a truncated cone.

[0052] 2a, the low-resolution image projection 50 comprises an array of light segments 51, for example having 5 rows and 20 columns. The native resolution of the illumination module 1 shown thereby comprises 20×5 light segments 51. Although only 100 light segments 51 are shown, the light source 3 can be configured such that several thousand light segments 51 are projected or emitted by the illumination module 1 within the projection angle range P.

[0053] 1 can temporarily deflect the light beam 30 emitted by the light source 3 and thus also the projection 50. The inherent resolution of the illumination module 1 can thereby be visually increased by at least temporary light beam deflection using the deflection unit 4.

[0054] Preferably, the deflection unit 4 is arranged in the optical path of the light bundle 30 between the light source 3 and at least a part of the projection unit 5. (Between) at least a part of the projection unit 5 means that the projection unit 5 may be composed of a plurality of optical elements as described above, and the deflection unit 4 may be arranged between (a part of) these optical elements.

[0055] The deflection unit 4 can receive a deflection control signal 41 and deflect the light beam 30 emitted by the light source 3 depending on the deflection control signal 41. Thereby, the low-resolution image projection 50 can be temporarily deflected within a projection angle range P depending on the deflection control signal 41. The module control unit 2 can be configured to provide the deflection control signal 41.

[0056] The deflection unit 4 may comprise a glass plate 42, which is made of a material that is transparent to the light beam 30 emitted by the light source 3. This glass plate 42 may be configured as a flat parallel plate and may be supported by a suitable mechanical suspension so as to be pivotable about at least one pivot axis x, which preferably lies perpendicular to the light propagation direction of the light beam 30 emitted by the light source 3. For example, the deflection unit 4 may further comprise an electromagnetic actuator (not shown), which temporarily pivots the glass plate 42 about the at least one pivot axis x depending on a deflection control signal 41. By this pivoting, the angle of incidence of the light beam 30 into the glass plate 42 may be temporarily changed, so that, depending on the light refraction, the light beam 30 may be deflected parallel to the light propagation direction of the light beam 30 during the light passage through the glass plate 42. Thereby the projection 50 of the light bundle 30 emitted by the light source 3 or the projection 50 of the low-resolution image can be deflected towards the front of the illumination module 1. This situation is explained in more detail on the basis of figure 2b.

[0057] The skilled person is aware of a wide variety of possibilities for creating such a deflection unit 4. For example, a prism (not shown) is conceivable, which can deflect the light bundle 30 or the low-resolution image projection 50 within the projection angle range P by a lateral change of position (with respect to the light propagation direction of the light bundle 30) and thus also by refraction. A reflective solution of the deflection unit 4 is also possible.

[0058] By at least temporarily deflecting the projections 50 of the low-resolution image within the projection angle range P, the illuminable angle range is expanded, as shown in Fig. 2b. In particular, by using a sufficiently fast and repetitive deflection, or a sufficiently high deflection frequency of at least 30 Hz, preferably between 30 Hz and 160 Hz, the deflected projections 52 and the non-deflected projections 50 can be made to visually overlap, forming a visual light segment 51v, which visually increases the resolution of the illumination module 1. Obviously, this overlap is obtained due to the inertia of the human eye (persistence of vision: persistence of vision), but for the sake of simplicity it will be referred to as overlapping.

[0059] The at least temporary deflection of the projection 50 within the projection angle range P thus means a movement (slide) of the projection 50 within the possible radiation cone, i.e. within the angular space provided by the projection unit 5. The projection angle range P preferably has a horizontal and a vertical extent, whereby the horizontal extent may be greater than the vertical extent, for example the horizontal extent covers an angular range of at most 50° and the vertical extent covers an angular range of at most 20°.

[0060] In the sense of this specification, the undeflected projection 50 and the deflected projection 52 each refer to a projection of the same low-resolution image, i.e. the visual overlap of the low-resolution image with itself results from the visual overlap of the deflected projection 50 and the undeflected projection 52 of the same low-resolution image. The magnitude (degree) of the overlap of the low-resolution image with itself can be described based on at least one deflection parameter.

[0061] In the present case, the maximum deflection by the deflection unit 4 is configured such that the deflected projection 52 has a vertical as well as a horizontal offset of substantially half a light segment width compared to the undeflected projection 50. Each light segment 51, except for the edge light segments, overlaps with four undeflected light segments 51 of the same low-resolution image at the maximum deflection shown here. The perceived resolution can thus be approximately four times the intrinsic resolution.

[0062] Fig. 3 shows a first flow chart, in which in a first step a) a target image S is received. This target image S has a resolution that exceeds the inherent resolution of the projection module 1. The target image S can be contained in a given image signal. The target image S can also constitute a part of a larger image, which has a higher resolution than the target image S. This means that the target image S can constitute a section of the larger image.

[0063] In a next step b), the target image S received according to step a) is transformed according to a first transformation rule into a first low-resolution image A. This first low-resolution image A is selected such that it has the inherent resolution of the illumination module 1. Furthermore, the first low-resolution image A is selected such that an at least partial visual overlap with itself produces an image impression more similar to the target image S than the imaging of the first low-resolution image A itself.

[0064] The first transformation rule can be executed by the module control unit 2. The module control unit 2 can thus be configured to execute the first transformation rule. Preferably, however, the first transformation rule is executed by an external calculation unit 7. That is to say, the external calculation unit 7 can be configured to receive the target image S according to step a). Furthermore, the external calculation unit 7 can be configured to execute the first transformation rule according to step b). In this case, the external calculation unit 7 is preferably not part of the illumination module 1.

[0065] The first low-resolution image A can be recallably stored in the storage unit 6 of the projection module 1. When the first transformation rule is executed by an external calculation unit 7, the external calculation unit 7 can be configured to recallably store the first low-resolution image A in the storage unit 6 of the projection module 1. In this case, the module control unit 2 can be configured to recall the first low-resolution image A stored in the storage unit 6.

[0066] The first transformation rule preferably comprises at least an approximate solution of a system of linear equations (Gleichungssystem). This system of equations comprises a set of linear equations and can be written in the form Sv=Km·Av. "Km·Av" corresponds to matrix-vector multiplication. Sv represents a vector with a predefined number of target intensity values, which corresponds to the resolution of the target image S. In other words, for a target image resolution of 40x10, the vector Sv comprises 400 components. This system of linear equations thus comprises 400 equations in this example. Similarly, Av represents a vector with a predefined number of determined intensity values, which corresponds to the resolution of the first low-resolution image A. The approximate solution of the system of linear equations thus comprises in this example 100 determined intensity values. By partial overlap of the first low-resolution image A with itself, a relationship between the determined intensity values ​​and the target intensity values ​​is obtained. This relationship is described on the basis of the connex matrix (transformation matrix) Km, which thus describes the behavior of each light segment 51 within its partial visual overlap with adjacent light segments 51 for each individual target light intensity value. The connex matrix Km thus corresponds to a matrix having 400×100 elements.

[0067] The set of linear equations, and thus the number of linear equations, therefore depends on the resolution of the target image S and on the resolution of the first low-resolution image A or the intrinsic resolution of the illumination module 1 .

[0068] The vector Sv having a predetermined number of target light intensity values, as well as the connex matrix Km, together can be referred to as "information of the target image S with respect to the first low-resolution image A within at least partial overlap with itself."

[0069] The connex matrix Km can be calculated or measured.

[0070] If the connex matrix Km is calculated, said information of the target image S further comprises at least one deflection parameter. In the present example, two deflection parameters are provided, which describe the vertical offset as well as the horizontal offset of substantially half the light segment width.

[0071] In measuring the connex matrix Km, for example, each individual light segment 51 can be activated individually to detect the effect of each individual light segment 51 in a repetitively deflected manner on all or at least a portion of the corresponding target light intensity values.

[0072] The construction of the first transformation rule as an at least approximate solution of the linear equation system may include corresponding methods for balancing and / or regularization. A preferred construction of the first transformation rule as an at least approximate solution preferably includes an iterative solution of the linear equation system.

[0073] In a further step c), the illumination module 1 is controlled in such a way that within a first time range T1, a first low-resolution image A converted according to step b) is emitted by the illumination module 1. The module control unit 2 can provide a corresponding light control signal 31 to the light source 3, so that a corresponding light bundle 30 is emitted by the light source 3. This light bundle 30 is emitted in the form of a projection 50 by the projection unit 5 in front of the illumination module 1, as already mentioned. In this context, this projection 50 corresponds to the first low-resolution image A. Preferably, the first low-resolution image A is emitted by the illumination module 1 continuously within the first time range T1.

[0074] If the first low-resolution image A is stored in a retrievable manner in the memory unit 6 of the illumination module 1, the module control unit 2 can be configured to recall the first low-resolution image A from the memory unit 6 and output an optical control signal 31 based thereon.

[0075] Furthermore, within the first time range T1, the first low-resolution image A is repeatedly deflected by means of the deflection unit 4, so that the first low-resolution image A is at least partially visually overlapped with itself within the first time range T1. The module control unit 2 can send a corresponding deflection control signal 41 to the deflection unit 4, so that the first low-resolution image A or its projection 50 is repeatedly deflected. For this purpose, the deflection control signal 41 can also be repeatedly sent to the deflection unit 4. Preferably, the repeated deflection of the first low-resolution image A is continuously active within the first time range T1.

[0076] The provision of the light control signal 31 for emitting the first low-resolution image A and / or the output of the deflection control signal 41 for activating the repetitive deflection by the deflection unit 4 may start a first time range T1. The output of the light control signal 31 for emitting a low-resolution image different from the first low-resolution image A and / or the output of the deflection control signal 41 for deactivating the repetitive deflection by the deflection unit 4 may end the time range T1.

[0077] Fig. 4a shows a second flow chart. In this second flow chart, a further configuration of the method is shown, where again in a first step a) a target image S is received. This target image S has a resolution that exceeds the inherent resolution of the illumination module 1. In a next step b) (left side of the figure), the target image S received according to step a) is transformed into a first low-resolution image A according to a first transformation rule. The transformation of the target image S into the first low-resolution image A has already been described based on Fig. 3, so that it will not be further described here.

[0078] Furthermore, in the same next step b) (left side of the figure), the target image S received according to step a) is transformed according to a second transformation rule into a second low-resolution image B. The second low-resolution image B is selected such that it has the inherent resolution of the illumination module 1. Furthermore, the second low-resolution image B is selected such that it has an image impression which is more similar to the target image S on its own than the first low-resolution image A.

[0079] The second transformation rule may be executed by the module control unit 2, whereby the module control unit 2 may be configured to execute the second transformation rule. However, preferably, the second transformation rule is executed by the external calculation unit 7, i.e. the external calculation unit 7 may be configured to execute the second transformation rule.

[0080] The second transformation rule preferably includes a scaling method, which preferably includes reducing the resolution of the target image S to the inherent resolution of the illumination module 1, with the resulting second low-resolution image B being entirely composed of the information of the target image S. Thus, for example, the scaling method is the known "downsampling" method, which discards, for example, every second target intensity value of the target image S and subsequently composes the intensity values ​​of the second low-resolution image B from the remaining target intensity values. It is also possible to use a block processing method, in which the target intensity values ​​of the target image S are combined block by block to form the individual intensity values ​​of the second low-resolution image B. Combining the target intensity values ​​block by block means, for example, that in each case the average value of four adjacent target intensity values, i.e. the average value of a 2x2 block, is formed and then one intensity value of the second low-resolution image B is calculated. Instead of the average value formation, other methods can also be used, for example median value formation. The skilled person is aware of very different scaling methods, which will not be described in detail.

[0081] In a further step b1) (left and right sides of the figure), the first low-resolution image A transformed in the previous step b) and the second low-resolution image B transformed in the previous step b) can be recallably saved (stored) in a storage unit 6. The module control unit 2 can be configured to recall the low-resolution images A, B stored in the storage unit 6.

[0082] If the second transformation rule is executed by an external calculation unit 7, this external calculation unit 7 may be configured to store the second low-resolution image B in a recallable manner in the memory unit 6 of the projection module 1 in a further step b1).

[0083] If the target image S has continuous light and dark extensions (light and dark boundaries), especially if the target image S has continuous light and dark extensions in the form of symbols (explained later), it is advantageously possible to convert the first resolution image A and the second low-resolution image B already before the intended use of the illumination module 1. The conversion before the intended use of the illumination module 1 can be sensible, especially if high computing power is required to convert the low-resolution images A, B from the target image S. In this case too, the previously converted low-resolution images A, B are stored in the storage unit 6 so as to be retrievable, as already described. The intended use of the illumination module 1 can include, for example, the preferred use of the illumination module 1 in an automotive lamp 10.

[0084] Fig. 4b shows a third flow chart, which is alternately explained in relation to Fig. 4c. Fig. 4c shows a time chart of a further configuration of the method with a first time range T1 and a second time range T2. Furthermore, the time chart shows a light control signal 31 and a deflection control signal 41.

[0085] The third flow chart relates to a motor vehicle 100 with a corresponding illumination module 1, whereby data of the motor vehicle 100 are continuously processed. The module control unit 2 can be configured to receive and process the data of the motor vehicle 100 together with the corresponding control parameters and to output the light control signal 31 and the deflection control signal 41 on the basis thereof. These data of the motor vehicle 100 can include information on at least one of the following criteria: -Target light function -Ambient temperature -Ambient brightness - Irradiation module status -Vehicle speed

[0086] In this case, the criteria of the target light function may include a description of a required light (light illumination) scenario. For example, the required light scenario may be a dynamic ADB function (adaptive driving beam) or ground projection. In this case, ground projection means the presence of a target image S having a plurality of continuous light and dark extensions C that together form a symbol. However, the required light scenario is not limited to the above examples. It is also possible that the required light scenario includes a combination of the dynamic ADB function and ground projection.

[0087] The ambient temperature may include the ambient temperature of the motor vehicle 100, the ambient temperature of the motor vehicle lamp 10, the ambient temperature of the illumination module 1 and / or preferably the ambient temperature of the deflection unit 4. In this case, the ambient temperature means, for example, the direct temperature of the object.

[0088] The ambient lighting may include the lighting surrounding the automobile 100 .

[0089] The illumination module state may include the state of one or more components of the illumination module 1. For example, the illumination module state includes an actuator state or a storage unit state. The actuator state may represent the state of the deflection unit 4. The actuator state could for example divide the state into faulty or non-faulty. A faulty actuator state could for example represent a state of the deflection unit 4 which cannot perform a prescribed repetitive beam deflection. The storage unit state could represent the state of the storage unit 6.

[0090] The vehicle speed may include the speed of the automobile 100 .

[0091] According to the third flowchart, the data of the vehicle 100 is appropriately processed to obtain a decision basis for activating or deactivating the repetitive light beam deflection by the deflection unit 4, as well as a decision basis for emitting a first low-resolution image A or a second low-resolution image B.

[0092] According to a further configuration of the method, e.g. if ground projection is required as a light scenario during operation, a pre-stored first low-resolution image A can be called up by the module control unit 2 and a corresponding light control signal 31 can be output to the light source 3. Furthermore, a corresponding deflection control signal 41 can be output by the module control unit 2 to the deflection unit 4 in order to activate a repetitive beam deflection by the deflection unit 4.

[0093] The provision of the light control signal 31 for emitting the first low-resolution image A and / or the output of the deflection control signal 41 for activating the repetitive deflection by the deflection unit 4 can start a first time range T1 and possibly end a second time range T2 if the second time range T2 has already been started before. What is essential is that within the first time range T1 a first low-resolution image A is emitted by the illumination module 1 and that this first low-resolution image A is repetitively deflected by means of the deflection unit 4 within the first time range T1.

[0094] According to a further configuration of the method, for example in case of a faulty actuator state, a pre-stored second low-resolution image B can be called up by the module control unit 2 and a corresponding light control signal 31 can be output to the light source 3. Furthermore, a corresponding deflection control signal 41 can be output by the module control unit 2 to the deflection unit 4 in order to terminate the repetitive light beam deflection by means of the possibly present deflection unit 4.

[0095] The output of the light control signal 31 for emitting the second low-resolution image B and / or the output of the deflection control signal 41 for deactivating the deflection unit 4 can start a second time range T2 and possibly end the first time range T1 if the first time range T1 was already started before. The essence is that within the second time range T2 the second low-resolution image B is emitted by the illumination module 1 and that this second low-resolution image B is not repeatedly deflected by means of the deflection unit 4 within the second time range T2.

[0096] Thus, the duration and / or start of the first time range T1 and the duration and / or start of the second time range T2 can be determined by at least one control parameter, which contains information on at least one of the above criteria. This of course presupposes that the lighting module 1 itself is activated. A deactivated lighting module 1 or a deactivated automotive light 10, or a lighting module 1 that is not activated due to other actions, does not allow the existence of such time ranges T1, T2 and will not be discussed here, but it is clear that a lighting module 1 that must be deactivated due to other actions will force the end of the possibly preceding first time range T1 or the preceding second time range T2.

[0097] The start of the second time range T2 is not tied to the existence of the preceding first time range T1. Similarly, the start of the first time range T1 is barely tied to the existence of the preceding second time range T2. Also, multiple first time ranges T1 can be started in chronological succession. Similarly, multiple second time ranges T2 can be started in chronological succession. Also, the first time ranges T1 and the second time ranges T2 can be started in chronological succession many times in alternation.

[0098] The ambient temperature can be, for example, treated in such a way that the ambient temperature of the actuator unit 4 leads to emission of a first low-resolution image A with repeated beam deflection up to a predefined upper limit, and above said upper limit the ambient temperature of the actuator unit 4 leads to emission of a second low-resolution image B without repeated beam deflection, whereby the upper limit of the ambient temperature of the actuator unit 4 can lie between 40° C. and 85° C.

[0099] The ambient brightness can be processed, for example, in such a way that the ambient brightness leads to emission of a first low-resolution image A with repeated beam deflections up to a predefined upper limit, and above said upper limit the ambient brightness leads to emission of a second low-resolution image B without repeated beam deflections, the upper limit of the ambient brightness being between 1000 and 7000 lux.

[0100] The vehicle speed can for example be processed in such a way that the vehicle speed leads to emission of a first low-resolution image A with repeated beam deflections up to a predefined upper limit value, and above said upper limit value the vehicle speed leads to emission of a second low-resolution image B without repeated beam deflections, the upper limit value of the vehicle speed being situated between 2 km / h and 30 km / h.

[0101] FIG. 5 shows a comparison of an example target image S, a first low-resolution image A transformed from the example target image S, the first low-resolution image A within an overlap with itself, and a second low-resolution image B transformed from the target image S.

[0102] In this description of the drawings, the same reference numerals are used in part as in the description of the previous drawings, but the contents of the description may be partially different, for example, other resolutions are shown to make the drawings easier to understand, etc. Therefore, the viewpoints described here are nevertheless in no way distinct from the viewpoints already described, but rather show the wide applicability of the present invention as defined by the entire scope of protection of the claims.

[0103] The target image S has here an exemplary target light distribution LV (top row). This exemplary target light distribution LV includes a number of continuous light and dark extensions (light and dark boundary contours) C, which together form a symbol. The continuous light and dark extensions C are boundary lines without gaps between light and dark areas. The transitions between light and dark areas can also be designed to be flowing (or smooth: fliesend). The target image S shown in the form of a target light distribution LV has a resolution that exceeds the resolution of the illumination module 1. In particular, the target image S shown in this figure has a resolution of 160x160. The shown target image S therefore includes 160x160 target light intensity values.

[0104] Furthermore, a first low-resolution image A converted according to the method can be seen (second from the top). This first low-resolution image A has a resolution of 80x80. In this case, a resolution of 80x80 would correspond to the resolution of the illumination module 1. The first low-resolution image A shown therefore contains 80x80 light intensity values.

[0105] According to the method, this first low-resolution image A is emitted by the illumination module 1 and is iteratively deflected by the deflection unit 4. The resulting overlap of the first low-resolution image A with itself can be seen in the figure as the third image from the top. Due to the iterative beam deflection, the resolution perceived by the human eye is increased compared to the intrinsic resolution of 80x80. The magnitude of the deflection in this case corresponds to a vertical offset as well as a horizontal offset of substantially half a segment width.

[0106] A comparison of the first low-resolution image A transformed according to the first transformation rule shown here with the target image S shows a structural similarity of 0.89 (second from the top). In contrast, a comparison of the target image S with the low-resolution image A in its overlap with itself shows a structural similarity of 0.93 (third from the top). The image impression of the first low-resolution image A in its visual overlap with itself is therefore more similar to the target image S than the imaging of the first low-resolution image A itself. The similarity is determined here on the basis of a structural similarity (SSIM - structural similarity index measure), whereby a scaling to the corresponding resolution is partly required. However, other suitable algorithms are also known for comparing images.

[0107] Furthermore, a second low-resolution image B can be seen (top row) which has been converted according to a further configuration of the method, this second low-resolution image B also having a resolution of 80x80.

[0108] According to a further configuration of the method, this second low-resolution image B is emitted by the illumination module 1 and is not repeatedly deflected by means of the deflection unit 4, so that no overlap of the second low-resolution image B with itself is obtained. A comparison of the second low-resolution image B shown here with the target image S shows a structural similarity of 0.92. The second low-resolution image B itself therefore has an image impression that is more similar to the target image S than the first low-resolution image A.

[0109] Now, finally, FIG. 6 shows a motor vehicle 100 with a lighting module 1 for a motor vehicle lamp 10, where the lighting module 1 is in a defined mounting position. The motor vehicle 100 and / or the lighting module 1 are configured to at least partially control the method. The motor vehicle 100 can be configured to perform a first part of the method, for example steps a) and b). The lighting module 1 is configured to be controlled according to at least step c) of the method. It is also possible that the motor vehicle 100 and / or the lighting module 1 are configured to perform all steps of the method. Preferably, an external computing unit 7 is configured to perform steps a) and b) of the method, where the external computing unit 7 is not part of the lighting module 1.
