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 with 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 using the deflection unit. [Background technology]

[0003] The prior art has become known to provide methods for controlling illumination modules that allow for time-variable modification 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 increased visual resolution, methods have become known in which the inherent resolution of the illumination module can be visually increased by using a deflection unit to at least temporarily modify the light beam using the 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 by visually overlapping two different images. For this purpose, two different images are calculated from an input image. These two different images are output in time succession using physically separate synchronization signals for the deflection units. This synchronization is obviously very complex and resource-intensive. [Prior art documents] [Patent documents]

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, 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, 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) 14. The illumination module according to claim 13, further comprising 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 preferred 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 motor vehicle equipped with an illumination module according to aspect 13 or 14, wherein the motor vehicle and / or the illumination module are configured to at least partially perform the 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 each image. Accordingly, "native resolution" is the resolution provided 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 (light-emitting 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, structural groups, constituent elements, components or combinations thereof.

[0013] By at least temporarily or repeatedly deflecting the light beams using 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 at least temporarily deflecting the light beams is achieved by 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] With regard to the question of image similarity, those skilled in the art know 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. Extensive information about these concepts is available online, including 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 using 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 (row and column) 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 and a horizontal offset (shift) of substantially half the light segment width compared to the undeflected reference state, so that at the maximum amplitude of deflection, each deflected light segment, except for the edge light segments, visually overlaps with substantially four undeflected light segments.

[0020] In this case, the light segments, except for the edge light segments, visually overlap spatially by 25 percent in repeated deflections. This allows the perceived resolution to 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 therefore represents the edge region of the image to be projected.

[0021] The magnitude of the 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 cause 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 include information about 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 a 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] The information of the target image relative to the first low-resolution image in at least partial overlap with itself may further include at least one deflection parameter.

[0027] For reasons of efficiency, the first transformation rule can be executed by an external computing unit, and the first low-resolution image is preferably stored (stored) in a memory unit of the illumination module so that it can be recalled.Moreover, advantageously, in step b), the target image received in step a) can be additionally transformed into a second low-resolution image based on a second transformation rule, wherein the second low-resolution image is selected so that it has the inherent resolution of the illumination module and, further, the second low-resolution image is selected so that it has an image impression more similar to the target image than the first low-resolution image, and in step c), the second low-resolution image is emitted by the illumination module within a second time range, wherein, within the second time range, the second low-resolution image is not repeatedly deflected using the deflection unit.

[0028] That is, 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-by-block 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, wherein 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 performed by an external computing 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 before 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-dark extension (light-dark boundary), and preferably the target image has multiple continuous light-dark extensions, which together form a single symbol.

[0035] The present invention further relates to an illumination module for a motor vehicle lamp, wherein the illumination module is configured to emit a segmented light distribution, wherein the illumination module includes 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, wherein the illumination module is configured to be controlled at least according to step c) of the above-mentioned method.

[0036] In this case, the illumination 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, thereby causing either the first low-resolution image or the second low-resolution image to be emitted by the illumination module.

[0038] The module control unit is further configured to control the deflection unit so that, when the first low-resolution image is emitted 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 so that, when the second low-resolution image is emitted by the illumination module, the deflection unit does not repeatedly deflect the second low-resolution image.

[0039] Furthermore, the invention relates to a motor vehicle equipped with such an illumination module, wherein the motor vehicle and / or the illumination module are configured to at least partly carry out the method described above.

[0040] All device components described in the method, unless otherwise specified, can also form part of an illumination module for a vehicle lamp. Conversely, all device components described in connection with 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 vehicle floodlight. The illumination module is preferably configured for use in a vehicle lamp, in particular for use in a signal lamp or a 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 explanation of the drawings]

[0042] [Figure 1] FIG. 1 shows a schematic diagram of one illumination module. [Figure 2a] FIG. 1 shows a schematic diagram of one low-resolution image. [Figure 2b] FIG. 1 shows a schematic diagram of the overlap of two low-resolution images. [Figure 3] FIG. 1 shows a first flow chart according to the method described. [Figure 4a] FIG. 10 shows a second flowchart according to a further configuration of the method. [Figure 4b] FIG. 10 shows a third flowchart according to a further configuration of the method. [Figure 4c] FIG. 10 shows a time chart according to a further configuration of the method. [Figure 5] 10A and 10B show 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. [Example]

[0043] Figure 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 includes 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 includes an electronic memory. Figure 1 also shows an external calculation unit 7.

[0044] A wide variety of techniques are already known for generating segmented light distributions. These include, inter alia, surface-based modulation using LEDs (light-emitting diodes) arranged in a matrix, surface-based light modulation using LCDs (liquid crystal displays), or surface-based light modulation using DLPs (digital light processing) or DMDs (digital mirror devices). Alternatively, beam modulation techniques are also known, i.e., scanning systems that scan a light beam or beam over a predetermined area using frequencies imperceptible to the human eye, thereby generating freely adjustable light distributions. Currently known high-resolution illumination modules already allow resolutions with thousands of individually switchable and light-adjustable light segments, preferably arranged in an aspect ratio of 1:4, with the greater extension direction being horizontal.

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

[0046] The light source 3 shown in FIG. 1 can include multiple elements. For example, the light source 3 includes a light-emitting element and a subsequent surface modulator (not shown), such as 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 1,000 individually controllable LEDs arranged in an array with an aspect ratio of 1:4. Alternatively, the light source 3 can include a combination of a light-emitting element, a collimator, and a beam modulator, which scans the collimated light of the light-emitting element over a predetermined area using a frequency imperceptible to the human eye. A light-conversion element can be arranged within the area. The light source 3 can thus be composed of multiple elements. Additional elements, such as optical lenses or reflectors, can be provided, but these are not shown for clarity.

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

[0048] For this purpose, the light source 3 can receive a light control signal 31 and 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 part of an image signal that includes at least a low resolution image.

[0050] A light beam 30 emitted by the light source 3 is projected by the 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. A corresponding 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 typically includes a number of optical elements, in particular lenses. For the sake of clarity, these optical elements are not shown in the drawings.

[0051] The projection angle range P is determined by the aperture of the projection unit 5. This means that the projection angle range P corresponds to the largest possible radiation cone of the projection unit 5. Such a radiation cone relates to a cone in the mathematical sense, which may also include all its sub-variations, such as a pyramid or a truncated cone.

[0052] 2a, the low-resolution image projection 50 includes an array of light segments 51 having, for example, 5 rows and 20 columns. The native resolution of the illumination module 1 shown thereby includes 20 x 5 light segments 51. Although only 100 light segments 51 are shown, the light source 3 can be configured such that thousands of 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 deflection of the light beam by means of the deflection unit 4.

[0054] Preferably, the deflection unit 4 is arranged in the optical path of the light beam 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 include a glass plate 42 made of a material transparent to the light beam 30 emitted by the light source 3. The glass plate 42 may be configured as a flat, parallel plate and may be supported by a suitable mechanical suspension mechanism 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 include an electromagnetic actuator (not shown) that temporarily pivots the glass plate 42 about the at least one pivot axis x depending on a deflection control signal 41. This pivoting temporarily changes the angle of incidence of the light beam 30 into the glass plate 42, so that, depending on the light refraction, the light beam 30 can be deflected parallel to the light propagation direction of the light beam 30 during its passage through the glass plate 42. This allows the projection 50 of the light bundle 30 emitted by the light source 3 or the projection 50 of the low-resolution image to be deflected towards the front of the illumination module 1. This situation is explained in more detail with reference to Figure 2b.

[0057] Those skilled in the art are aware of a wide variety of possibilities for creating such a deflection unit 4. For example, a prism (not shown) is conceivable, which, by changing its position laterally (with respect to the light propagation direction of the light beam 30) and thus also by refraction, can deflect the light beam 30 or the low-resolution image projection 50 within the projection angle range P. Reflective solutions of the deflection unit 4 are also possible.

[0058] By at least temporarily deflecting the low-resolution image projections 50 within the projection angle range P, the irradiable angle range is expanded, as shown in FIG. 2b. In particular, by using sufficiently fast and repetitive deflections, or by using 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 (overlap). This allows the formation of visual light segments 51v, which visually increase the resolution of the illumination module 1. Obviously, this overlap is achieved due to the inertia of the human eye (persistence of vision), but for simplicity and clarity, 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 extension and a vertical extension, whereby the horizontal extension may be greater than the vertical extension, for example the horizontal extension covers an angular range of at most 50° and the vertical extension 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 represent a projection of the same low-resolution image, i.e., the visual overlap of a 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 overlap of a low-resolution image with itself can be described based on at least one deflection parameter.

[0061] In this case, the maximum deflection by the deflection unit 4 is configured so that the deflected projection 52 has a vertical and horizontal offset of substantially half the light segment width compared to the undeflected projection 50. This causes each light segment 51, except for the edge light segments, to overlap with four undeflected light segments 51 of the same low-resolution image at the maximum deflection shown here. This allows the perceived resolution to be approximately four times the intrinsic resolution.

[0062] 3 shows a first flowchart, in which in a first step a) a target image S is received. This target image S has a resolution that exceeds the native resolution of the illumination module 1. The target image S can be contained in a predetermined image signal. The target image S can also form part of a larger image, which has a higher resolution than the target image S. This means that the target image S can form a section of the larger image.

[0063] In a next step b), the target image S received according to step a) is transformed into a first low-resolution image A according to a first transformation rule, which is selected such that the first low-resolution image A has the native resolution of the illumination module 1. Furthermore, the first low-resolution image A is selected such that at least a 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 therefore be configured to execute the first transformation rule. Preferably, however, the first transformation rule is executed by an external calculation unit 7. That is, 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 illumination 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 illumination 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 includes at least an approximate solution of a linear equation system (simultaneous linear equations: Gleichungssystem). This equation system includes 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 predetermined number of target intensity values, which corresponds to the resolution of the target image S. For a target image resolution of 40x10, the vector Sv includes 400 components. Thus, in this example, this linear equation system includes 400 equations. Similarly, Av represents a vector with a predetermined number of determined intensity values, which corresponds to the resolution of the first low-resolution image A. Thus, in this example, the approximate solution of the linear equation system includes 100 determined intensity values. The relationship between the determined intensity values ​​and the target intensity values ​​is obtained by the partial overlap of the first low-resolution image A with itself. This relationship is described on the basis of a connex matrix (transformation matrix) Km, which thus describes the effect of each light segment 51 within its partial visual overlap with adjacent light segments 51 on each individual target light intensity value. The connex matrix Km therefore corresponds to a matrix with 400 x 100 elements.

[0067] The set of linear equations, and therefore the number of linear equations, therefore depends on the resolution of the target image S and 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, can together 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] When the connex matrix Km is calculated, the information of the target image S further comprises at least one deflection parameter, in this example two deflection parameters are provided, which describe the vertical and horizontal offsets 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 can include corresponding methods for balancing and / or regularization. The 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 such 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 by the projection unit 5 in the form of a projection 50 in front of the illumination module 1, as already described. In this connection, 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 may be configured to retrieve 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 using 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] 4a shows a second flowchart, which illustrates a further configuration of the method, in which again in a first step a) a target image S is received. This target image S has a resolution that exceeds the native resolution of the illumination module 1. In a next step b) (left side of the diagram), 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 with reference to FIG. 3, and therefore 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 into a second low-resolution image B according to a second transformation rule. The second low-resolution image B is selected such that it has the native resolution of the illumination module 1. Furthermore, the second low-resolution image B is selected such that it has an image impression that is more similar to the target image S 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. Preferably, however, 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 involves reducing the resolution of the target image S to the native resolution of the illumination module 1, with the resulting second low-resolution image B being entirely composed of information from 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 then constructs 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 in blocks to form individual intensity values ​​of the second low-resolution image B. Combining the target intensity values ​​in blocks means, for example, that in each case the average of four adjacent target intensity values, i.e., the average of a 2x2 block, is formed and then a respective intensity value of the second low-resolution image B is calculated. Instead of averaging, other methods can also be used, such as median formation. Those skilled in the art are aware of many 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 saved (stored) in a memory unit 6 so that they can be recalled. The module control unit 2 can be configured to recall the low-resolution images A, B stored in the memory 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 illumination 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 (described later), it is advantageous to convert the first resolution image A and the second low-resolution image B already before the intended use of the illumination module 1. This conversion before the intended use of the illumination module 1 can be useful, especially if a high computing power is required to convert the target image S into the low-resolution images A, B. In this case, too, the pre-converted low-resolution images A, B are stored in the storage unit 6 so that they can be recalled, 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] Figure 4b shows a third flowchart, which will be described in turn in relation to Figure 4c. Figure 4c shows a time chart of a further implementation of the method having 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 flowchart relates to a motor vehicle 100 equipped with a corresponding illumination module 1, where 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 based thereon. 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 for the target light function may include a description of a required 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, for example, the presence of a target image S having multiple 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 for the required light scenario to include 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 faultless. A faulty actuator state could for example represent the state of the deflection unit 4, which is unable to perform prescribed repetitive beam deflections. 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 motor vehicle 100 is suitably processed to obtain a decision basis for activating or deactivating the repeated 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] For example, if ground projection is required as a light scenario during operation, according to a further configuration of the method, 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 repeated beam deflections 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 started before. What is essential is that within the first time range T1 the first low-resolution image A is emitted by the illumination module 1 and that this first low-resolution image A is repetitively deflected using 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 beam deflection by means of the deflection unit 4, if any, present.

[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] The duration and / or start of the first time range T1 and the duration and / or start of the second time range T2 can thus be determined by at least one control parameter, which at least one control parameter contains information about 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 lamp 10, or a lighting module 1 that is not activated due to other actions, does not allow such time ranges T1, T2 to exist and will not be discussed here. However, 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 possibly 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 start in succession in time. Similarly, multiple second time ranges T2 can start in succession in time. Also, the first time range T1 and the second time range T2 can start in succession in alternating succession multiple times.

[0098] The ambient temperature can be adjusted, for example, so that the ambient temperature of the actuator unit 4 leads to emission of a first low-resolution image A with repeated beam deflections up to a certain upper limit, and that the ambient temperature of the actuator unit 4 above this upper limit leads to emission of a second low-resolution image B without repeated beam deflections, where 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, to result in emission of a first low-resolution image A with repeated beam deflections up to a certain upper limit, and above this upper limit in an ambient brightness to result in emission of a second low-resolution image B without repeated beam deflections, where the upper limit in an ambient brightness can lie between 1000 and 7000 lux.

[0100] The vehicle speed can be processed, for example, to result in emission of a first low-resolution image A with repeated beam deflections up to a predetermined upper speed limit, and in emission of a second low-resolution image B without repeated beam deflections above said upper speed limit, which can lie 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, some of the same reference numerals are used as in the previous description of the drawings, but the contents of the descriptions may be partially different. For example, other resolutions are shown to simplify the drawings. Therefore, the aspects described here are in no way distinct from the above-mentioned aspects, but rather illustrate the wide applicability of the present invention as defined by the entire scope of protection of the claims.

[0103] The target image S here has an exemplary target light distribution LV (top row). This exemplary target light distribution LV includes a plurality of continuous light and dark extensions (light and dark boundary contours) C that together form a symbol. The continuous light and dark extensions C are gap-free boundary lines between light and dark areas. The transitions between light and dark areas can also be configured to flow (or be smooth). The target image S shown in the form of the 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 present 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 repeatedly deflected by the deflection unit 4. The resulting overlap of the first low-resolution image A with itself can be seen as the third image from the top in the figure. Due to the repeated beam deflection, the resolution perceived by the human eye is increased compared to the intrinsic resolution of 80x80. In this case, the magnitude of the deflection corresponds to a vertical offset as well as a horizontal offset of essentially 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 within its overlap with itself shows a structural similarity of 0.93 (third from the top). Thus, the image impression of the first low-resolution image A within its visual overlap with itself is more similar to the target image S than the image of the first low-resolution image A itself. The similarity is determined here based on structural similarity (SSIM—structural similarity index measure), which partially requires scaling to the corresponding resolution. However, other suitable algorithms are also known for comparing images.

[0107] Furthermore, a second, lower resolution image B can be seen, which has been transformed according to a further embodiment of the method (maximum under This second, lower resolution image B also has 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 using 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] Finally, Fig. 6 shows a motor vehicle 100 equipped 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. The motor vehicle 100 and / or the lighting module 1 can also be 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.
