Description

DESCRIPTION Title: Method and device for representing a scene with personalized brightness

[0001] The present invention relates to a method for representing a scene on a display medium, making it possible to dynamically customize the brightness of the scene. It also relates to a computer program, a device, an apparatus and a vehicle implementing such a method.

[0002] The field of the invention is the field of displaying a scene on a display medium, such as a display screen or a projection surface associated with a projector. State of the art

[0003] When the human eye scans a scene, it observes the scene according to the brightness of the scene at the time it is observed. Techniques are known that propose imaging a scene with and without flash to obtain an image without flash and an image with flash of the same scene. The two images are then combined to obtain an improved representation of the scene. This technique makes it possible, on the one hand, to avoid saturating the image sensor for areas of the scene that are sufficiently lit and to increase the brightness of other areas of the scene that are not sufficiently lit. Thus, by combining the two images, we obtain an image of the scene that has satisfactory brightness, potentially for all parts of the scene.

[0004] However, these imaging techniques, although improving the brightness of the scene, give a fixed representation of the scene. In addition, an image obtained by these techniques does not adapt to the user based on the interest that the user may have in a particular area of ​​the scene.

[0005] An aim of the present invention is to remedy at least one of the aforementioned drawbacks.

[0006] Another aim of the invention is to propose a solution allowing a dynamic representation of a scene in terms of brightness.

[0007] Another aim of the invention is to propose a solution allowing a representation of a scene which adapts the brightness of said scene to a user observing the scene. Statement of the invention

[0008] The invention proposes to achieve at least one of the aforementioned aims by a method of representing a scene on a display medium, with: - at least a first image of said scene, and - at least a second image of said scene, representing said scene with greater brightness compared to said first image; said method comprising a step of displaying, on said display medium, the first image and at least one iteration of a display phase comprising the following steps: - reception of at least one position, called target position, relative to an area, called target area, of the scene in which the user is interested in said first image, and - modification, within said first image, of the brightness of the scene in said target area, from the second image.

[0009] Thus, like known techniques, the invention makes it possible to represent a scene from at least two images of the scene acquired with different brightnesses. But, unlike known techniques, the invention proposes to identify an area of ​​the scene as a function of a received target position, generally a position relative to an area of ​​the scene in which the user is interested, and to modify the brightness of the scene, only for this area by using the image with greater brightness.

[0010] Unlike known techniques, the invention therefore does not combine images of different brightnesses for the entire scene to generate a static representation of the scene. Furthermore, still unlike known techniques, the invention proposes to modify the brightness of an area of ​​the scene dynamically, depending on the target position received, for example depending on the position viewed by the user observing the scene on the display medium.

[0011] Thus, the invention makes it possible to produce a dynamic representation of the scene in terms of brightness, and in particular a representation of the scene with a brightness which adapts to a user observing the scene.

[0012] By image, we mean a digital image, and in particular a matrix image, and more particularly an RGB matrix image for example.

[0013] According to embodiments, for at least one target area, the modification of the brightness may comprise, or consist of, a replacement, within the first image, of said target area by the corresponding area of ​​the second image.

[0014] In this case, when the target area is identified on the first image, this same area is identified on the second image. The content of the second image is copied and displayed on the display medium within the first image, superimposed on or above the target area. Thus, the user observes the scene as it is represented by the first image with the exception of the target area which corresponds to the scene as it is represented by the second image.

[0015] This embodiment is easy to implement with limited computing resources.

[0016] According to embodiments, for at least one target zone, the modification of the brightness may comprise, or consist of, a replacement, within the first image, of said target zone by an image zone, called composite, obtained by combination: - of the target area in the first image, with - the corresponding area in the second image.

[0017] In this case, when the target area is identified in the first image, the corresponding area is identified in the second image. The contents of the second image for the corresponding area are copied and combined with the contents of the target area in the first image, to obtain a composite image area comprising the contents of the first and second images. Then, this composite image area is displayed on the display medium within the first image, superimposed on or above the corresponding area of ​​the first image.

[0018] Thus, the user observes the scene as it is represented by the first image with the exception of the target area which corresponds to a combination of: - of the scene as represented by the first image, and - of the scene as represented by the second image.

[0019] This embodiment makes it possible to obtain a better rendering in the representation of the scene during the display phase and in particular when modifying the brightness of the target area. More precisely, this embodiment makes it possible to achieve a better transition when modifying the brightness of the target area.

[0020] According to embodiments, the target position may be a point position on the first image.

[0021] In embodiments, the target position may be an area, also referred to as a target zone, that is larger than a point position.

[0022] The target position the user is interested in can be determined in different ways.

[0023] According to embodiments, the target position may be manually entered by the user.

[0024] In this case, the user manually selects the target position on the first image, for example using a pointer, such as a mouse, a trackball, or a directional pad moving a cursor, or any other position input device. The user can also enter the target position by touch selection on a touch surface arranged on the display medium in the case, for example, of a touch display screen, or offset from the display medium.

[0025] According to embodiments, the target position can be detected automatically by at least one sensor.

[0026] For example, the target position may be, or may be determined based on, a position aimed at by a part of the user's body, in the first image.

[0027] In this case, in particular, said body part may be at a distance from the display medium, and does not come into contact with said display medium or a control surface.

[0028] This part of the user's body can be a finger, or a hand, pointing towards the first image. In this case, it is the position aimed by the finger or hand located at a distance from the display support that is detected.

[0029] This body part can be an eye, or the user's eyes. In this case, it is the position targeted by the user's eye or eyes that is detected.

[0030] This body part can be a user's face. In this case, the orientation of the face is detected and a position aimed at a point on the face, for example the center of the face, is detected.

[0031] The position targeted by the user's body part may be detected, for example, by at least one sensor fitted to the display support, or a device integrated into the display support. The sensor may alternatively be arranged at a distance from said support, or said device.

[0032] The at least one sensor may be an optical sensor, an acoustic sensor, a capacitive sensor, etc. For example, in the case where the display medium is a touch screen, then the sensor may be a capacitive sensor equipping said touch screen.

[0033] Of course, other types of sensors can be used and the invention is not limited to a specific type of sensor.

[0034] According to embodiments, the target position may be detected by detecting a zoomed region of the first image.

[0035] Indeed, when the user zooms in on a region of the first image, this probably indicates that he is paying attention to the part of the scene located in said zoomed region. In this case, the target position may be the zoomed region, or may be a position in said zoomed region, such as for example a central position of said zoomed region.

[0036] Zoom can be applied in a known way: - tactilely by applying a movement, for example with two fingers. In this case, the target position can be the position equidistant from the positions of the fingers applying the zoom; - using a pointer surrounding the region to zoom; - etc.

[0037] At least one target area may be an area of ​​predetermined dimensions, such as a mask of predetermined size.

[0038] In this case, the target area does not change size depending on the target position. The target area is obtained by positioning the area of ​​predetermined dimensions, for example the mask, depending on the target position. For example, the target area can be obtained by positioning the area of ​​predetermined dimensions so that the target position is at the center of said area, at a corner of said area, etc.

[0039] According to embodiments, at least one target area may be drawn by the user.

[0040] In this case, the part of the scene within the drawn area is displayed with increased brightness. This allows the user greater freedom in choosing which areas to display with increased brightness. In other words, the user is not limited to the shapes, or objects, within the scene in choosing the target area.

[0041] At least one target area can correspond to an object in the scene. In this case, the target area is limited to the object.

[0042] This embodiment makes it possible to change, and in particular to increase, the brightness of an object on which the user's attention is focused, in relation to the rest of the scene.

[0043] For example, in the case of a scene comprising several objects, when the user's attention is focused on one of the objects, the latter is displayed with increased brightness compared to the rest of the scene, allowing better observation of said object. When the user's attention is focused on another object, the previously observed object regains its brightness as it is imaged in the first image, and this other object is displayed with increased brightness, and so on.

[0044] The first image can be obtained by any means, or by any technique.

[0045] According to embodiments, the first image can be obtained by calculation.

[0046] For example, the first image may be generated by an artificial intelligence model, for example from a description of the scene given to said artificial intelligence model. Such models are well known and widely used, such as for example ChatGPT ®.

[0047] Alternatively, the first image may be generated by computation from another image of the scene. For example, the first image may be generated from the second image: in this case, the second image may be digitally processed to decrease the brightness of said image and thus obtain the first image. According to another example, the first image may be generated from an image of the scene, called the source image, other than the second image. This source image may be an image whose brightness is greater or lower compared to that of the first image.

[0048] According to embodiments, the first image can be obtained by acquisition with an imaging device.

[0049] For example, the first image may be an image acquired by an imaging device: - without flash, or with a weaker flash compared to the second image, if applicable; and / or - with a shorter image sensor exposure time compared to the second image, if applicable.

[0050] The second image can be obtained by any means, or by any technique.

[0051] According to embodiments, the second image can be obtained by calculation.

[0052] For example, the second image may be generated by an artificial intelligence model, for example from a description of the scene given to said artificial intelligence model. Such models are well known and widely used, such as for example ChatGPT ®.

[0053] Alternatively, the second image may be generated by computation from another image of the scene. For example, the second image may be generated from the first image: in this case, the first image may be digitally processed to increase the brightness of said image and thus obtain the second image. According to another example, the second image may be generated from an image of the scene, called the source image, other than the first image. This source image may be an image whose brightness is greater or lower compared to that of the second image.

[0054] According to embodiments, the second image can be obtained by acquisition with an imaging device.

[0055] For example, the second image may be an image acquired by an imaging device: - with flash, or with a stronger flash compared to the first image, if applicable; and / or - with a longer image sensor exposure time compared to the first image, if applicable.

[0056] According to the invention, the display medium can be any type of display medium.

[0057] According to embodiments, the display medium may be a display screen, such as for example a screen of a smartphone, a tablet, a computer, a television, a virtual reality and / or augmented reality headset, etc.

[0058] According to embodiments, the display medium may be a surface onto which an image of the scene is projected, such as for example a display surface associated with a projector, etc.

[0059] According to embodiments, the display medium may be a medium worn by the user, for example a goggle, or glasses, a virtual reality headset, an augmented reality headset, etc.

[0060] According to embodiments, the display medium may be a display medium equipping the device carrying out the display phase, such as: - a display screen fitted to said device, for example in the case of a smartphone, a tablet, a virtual reality and / or augmented reality headset, etc. or - a projection surface equipping said device, for example in the case of an augmented reality or virtual reality headset.

[0061] According to embodiments, the display medium may be a medium independent of the apparatus carrying out the display phase, for example in the context of a projector projecting the images onto a display surface.

[0062] The display phase can be repeated as many times as desired with a different target position, from one iteration to another. Thus, an observer can move through a scene to observe different parts of said scene, each part being displayed with increased brightness when observed by the user. Thus, the brightness of the scene is adjusted, and in particular increased, as the scene is moved through by the user.

[0063] This allows for more ergonomic, personalized and dynamic navigation of a scene.

[0064] The invention can be implemented for the representation of a scene, at a given instant. In this case, the first image and the second image represent the same scene at the same instant.

[0065] The invention may be implemented for the representation of the scene at different times, for example at a video stream of the scene. In this case, the second image may represent the scene at a different time than that of the first image. For example, the second image may represent the scene at a time subsequent to, and in particular at a time following, that of the first image.

[0066] According to embodiments, at least one image of the scene may be a 2D image. In particular, the first image may be a 2D image. In particular, the second image is a 2D image.

[0067] According to embodiments, at least one image of the scene may be a 3D image. In particular, the first image may be a 3D image. In particular, the second image may be a 3D image.

[0069] The computer program can be in any computer language, such as machine language, C, C++, JAVA, Python, etc.

[0070] Such a computer program may be presented as a standalone application. Alternatively, such a computer program may be integrated into a photo or video application, or into an image or video playback application.

[0072] The device according to the invention can be, or be integrated into, any type of device such as a smartphone, a tablet, a computer, a calculator, a processor, a computer chip, programmed to implement the method according to the invention, for example by executing the computer program according to the invention.

[0075] According to embodiments, the apparatus according to the invention may comprise a means for detecting the target position in an automated manner.

[0076] In particular, the device may be a user device such as a smartphone, tablet, etc. comprising a display screen.

[0077] In this case, the user device may further comprise a means for automated detection, or manual entry, of the target position, such as for example a touch surface, in particular integrated into, or associated with, the display screen of said device.

[0078] In particular, the device may be a computer-type user device, comprising a display screen.

[0079] In this case, the computer-type user device may comprise a touch-sensitive surface, in particular integrated into, or associated with, the display screen of said computer, or a pointer moved, for example by a mouse, or a directional pad, to enter the target position.

[0080] In particular, the device may be a television.

[0096] Other advantages and characteristics will appear on examining the detailed description of non-limiting embodiments, and the attached drawings in which: - FIGURE 1 is a schematic representation of a non-limiting exemplary embodiment of a method according to the invention; - FIGURE 2 is a schematic representation of another non-limiting example of embodiment of a method according to the invention; - FIGURE 3 is a schematic representation of a non-limiting exemplary embodiment of a device according to the invention; - FIGURES 4-6 are schematic representations of a non-limiting exemplary embodiment of an apparatus according to the invention; and - FIGURE 7 is a schematic representation of a non-limiting exemplary embodiment of a vehicle according to the invention.

[0097] It is understood that the embodiments which will be described below are in no way limiting. In particular, it is possible to imagine variants of the invention comprising only a selection of characteristics described below isolated from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention compared to the state of the prior art. This selection includes at least one preferably functional characteristic without structural details, or with only part of the structural details if it is this part which is only sufficient to confer a technical advantage or to differentiate the invention compared to the state of the prior art.

[0098] In particular, all the variants and embodiments described can be combined with each other if there is no technical obstacle to this combination.

[0099] In the figures and in the rest of the description, the elements common to several figures retain the same reference.

[0100] FIGURE 1 is a schematic representation of a non-limiting exemplary embodiment of a method according to the present invention.

[0101] The method 100 of FIGURE 1 may be used to provide a representation of a scene on a display medium with a brightness that dynamically adjusts to a user viewing the scene, from at least two images of the scene having different brightnesses. For example, the method 100 may provide a representation of the scene with a first image IM1 of said scene having a lower brightness than a second image IM2 of said scene. For example, the image IM1 may have been acquired without flash and the image IM2 may have been acquired with flash. Although Of course, this example is given for information purposes only and other alternatives are possible such as those described above.

[0102] The method 100 comprises a step 102 of displaying the first image IM1 of the scene on a display medium. This image IM1 represents the scene with lower brightness compared to the second image IM2.

[0103] The display medium may be either a display screen, a display surface associated with a projector, or any other type of display medium, for example holographic.

[0104] The method 100 then comprises one or more iterations of a display phase 110 performing a dynamic representation with personalized brightness of the scene on the display medium, using the second image IM2.

[0105] The display phase 110 comprises a step 112 of determining a target position, POS, in which a user who observes the scene as represented by the first image IM1 displayed on the display medium is interested. The target position POS corresponds to a position on the first image IM1. According to an exemplary embodiment, the target position POS can be entered manually, using an input device which can be a keyboard, a mouse, a touch surface, etc. According to another exemplary embodiment, the target position POS can be detected automatically by at least one sensor, such as an optical sensor, a capacitive sensor, a camera, etc. detecting the position targeted by a finger, a hand, eyes, a face, and more generally a part of the user's body.

[0106] The display phase 110 comprises a step 114 of identifying a target area in the first image IM1 as a function of the target position POS. For example, the target area may be an object located at said target position POS. Alternatively, the target area may be an area: - of predetermined shape, for example circular, square, rectangular, etc.; and / or - of predetermined dimensions.

[0107] In the example described with reference to FIGURE 1, and without loss of generality, the target area may be an area of ​​predetermined shape and size, positioned as a function of the target position POS. For example, the target area may be centered on the target position POS. According to another exemplary embodiment, the target area may be positioned so that the target position POS corresponds to an edge or a corner of the target area, etc. Of course, other exemplary embodiments are possible.

[0108] The display phase 110 then comprises a modification of the brightness, within the image IM1, of the target area determined as a function of the target position POS. This modification can be carried out in different ways.

[0109] In the example of FIGURE 1, in a non-limiting manner, the area corresponding to the target area is identified in the second image IM2, during a step 116. It is recalled that the second image IM2 represents the scene with a greater brightness than that of the first image IM2.

[0110] The area of ​​the second image IM2, corresponding to the target area identified on the first image IM1, is copied during a step 118. [YES] In a step 120, the corresponding area of ​​the second image IM2 is displayed within the first image IM2 on the display medium. More particularly, the corresponding area of ​​the image IM2 is displayed superimposed on the first image IM1 above the target area. Thus, the user observes the scene as it is represented by the first image IM1 with the exception of the target area which corresponds to the scene as it is represented by the second image IM2.

[0112] Thus, the method 100 performs a representation of the scene by emphasizing the area of ​​the scene observed by the user. More particularly, the method performs a representation of the scene by increasing the brightness of the area of ​​the scene observed by the user.

[0113] By repeating the display phase 110 at a given frequency, it is possible to allow the user to navigate in the scene, that is to say to observe different parts of the scene, while increasing the brightness of each of these parts, in turn and as the user navigates through the scene.

[0114] FIGURE 2 is a schematic representation of another non-limiting exemplary embodiment of a method according to the present invention.

[0115] The method 200 of FIGURE 2 may be used to provide a representation of a scene on a display medium with brightness that dynamically adjusts to a user viewing the scene.

[0116] Method 200 includes all of the features of method 100 except for the differences noted below. In method 200, the modification of the brightness of the target area is performed differently than described for method 100.

[0117] In the method 200, the modification of the brightness of the target area comprises, or consists of, a replacement, within the first image IM1, of said target area by an image area, called composite, obtained by combination: - of the target area in the first image IM1, with - the corresponding area in the second image IM2.

[0118] In this case, the target area is identified on the first image IM1 in step 114, then the corresponding area is identified on the second image IM2 in a step 116. The corresponding area in the second image IM2 is copied / extracted in step 118.

[0119] Then, a step 202 performs a copy and / or an extraction of the target area in the first image IM1, in a similar manner to what is done for the corresponding area in the second image IM2 in step 118.

[0120] In a step 204 the target area extracted from the first image IM1 and the corresponding area extracted from the second image IM2 are combined to obtain a composite image area having a brightness greater than that of the target area in the first image IM1. For example, the composite image area can be obtained by performing an average, pixel by pixel: - the brightness of the target area extracted from the first image IM1, and - of the corresponding area extracted from the second image IM2 Of course, this example is given for non-limiting illustration purposes only and it is possible to obtain the composite image area according to any other combination of the target area extracted from the image IM1 with the corresponding area extracted from the second image IM2, for example a combination using different weights for each of the areas.

[0121] Then, in method 200 and unlike method 100, it is this composite image area which is used to be displayed on the display medium within the first image IM1, superimposed on or above the target area of ​​the first image IM1.

[0122] Thus, the user observes the scene as it is represented by the first image IM1 with the exception of the target area which corresponds to a combination of: - of the scene as represented by the first image IM1, and - of the scene as represented by the second image IM2.

[0123] The method 200 makes it possible to obtain a better rendering in the representation of the scene during the display phase 110 and in particular when modifying the brightness of the target area. More precisely, this embodiment makes it possible to achieve a better transition when modifying the brightness of the target area.
