Therefore, in accordance with the inventive concept, there is provided a flash unit comprising: at least one illumination unit for illuminating a target, each illumination unit comprising a light source; and (4) means for driving based on control data Per-lighting unit. The control component is configured to take the external data associated with the target and to derive the control data from the external data. Each light unit is adapted to provide the response in response to the control data: One of the sub-areas is scheduled for illumination. In addition to the light source, each of the light sheets 7L may optionally include an optical member for controlling the light from the light source, the flash unit being adapted to provide illumination suitable for a particular target. External data is typically retrieved from an external source and associated with the target (i.e., the scene that the flash unit is intended to illuminate). When the flash is used in a camera, it is preferably received from a camera imaging sensor (eg, 'a CCD device or a CM device that captures light from the scene and converts the light into an electrical signal) External information. It can also provide information about the scene (for example, a camera's auto focus sensor, lens zoom position or one camera movement sensor, 5 blood system one safety sensor) The sensor takes an external Ί^" . Further, the flash unit itself may be configured with a sensor for providing external data associated with the scene. The external data extracted by 159452.doc 201229645 forms the basis of the control data derived from the analysis of the external data and the calculation of the control signals according to the preset instructions. These analyses can be based on face detection, smile detection, motion detection or other image/sensor processing. The control data is then used to drive the illumination units to illuminate individual sub-areas of the scene in a predetermined manner. Thereby, at least one two-dimensional adaptation of the illumination of the scene is provided, wherein the adaptation is based on the scene. According to the flash device of an embodiment, external data is extracted from at least one of an imaging sensor matrix, an autofocusing member, an automatic illuminometer, a distance meter, and a motion sensor. ◎ Locally adjusting the flash The light output of the device is improved by a balance between the illumination of the remote portion of the scene and the portion of the scene. A fast moving object can receive a shorter, more powerful flash to freeze the movement. According to the flash unit of an embodiment, the predetermined illumination of the illumination units jointly covers a predetermined sub-portion of the target. This facilitates, for example, that a farther target in the target can receive more light from the flash than the target to produce a more natural illumination of the target. According to an embodiment of the invention, different sub-portions of the target can be illuminated with different light intensities. This can, for example, adjust the vignetting of the imaging lens such that, for example, the vignetting in the image due to vignetting is compensated for. The vignetting of the imaging lenses is effectively counteracted by arranging a two-fold increase in light intensity in the sub-portion of the darker target in the captured image. In an alternative method, the vignetting effect can be used in a predetermined manner to, for example, illuminate a person with respect to an environment in an image. II. From better illumination of a person in the background of a normal illumination, a vignetting effect can be achieved for, for example, artistic purposes. 159452.doc 201229645 Further, adjusting the vignetting can be included in the gossip The image is captured by the imaging sensor matrix to find (eg, #... ®® i, for example) the naturally occurring vignetting effect in the image and then adjust the illumination accordingly, to reduce, increase or Offseting the vignetting 0 According to the flash unit of the embodiment, the predetermined sub-portion of the target is selected based on the contrast difference and/or the color difference in the external data. According to the flash device of the embodiment, when the self-image sensor senses the external data and configures the predetermined illumination to provide at least a predetermined sub-region of the target-sequential illumination, the sequence and the imaging sensor matrix are The active imaging sub-area - the moving line is the same, or is located in front of the imaging sensor matrix by the movable aperture. The movable aperture can be a slot shutter or any similar mechanical shutter device. The flash is synchronized with the movement of the gap along the matrix of imaging sensors. This allows the flash to be used in combination with a shorter exposure time than conventional electronic flashes. According to the flash unit of an embodiment, the predetermined illumination is adjusted based on the depth variation of the target. Thus, the illumination has an adapted intensity relative to each sub-portion of the scene, the intensity being dependent on the distance from the device (e.g., camera) on which the flash unit is disposed. So one of the goals is more natural. According to an embodiment of the flash device, the predetermined illumination of the illumination units is configured to jointly cover a predetermined sub-portion of a target of a moving object, when photographing a moving object (such as a ball in a ball sport) or when lighting This is advantageous when one of the moving sensors in one of the monitoring systems detects one of the moving objects. 159452.doc-6-201229645 According to an embodiment of the flash unit, the control data is configured such that the predetermined illumination has an adjusted color cast and/or color temperature. The color shift or color temperature is controlled in a predetermined manner. The predetermined manner may alternatively include analyzing the color cast or color temperature of the test image captured by the image sensor matrix and adjusting the illumination to a desired value. By controlling the color temperature, the scene can be selected to illuminate to set a mode in the image produced when the scene is captured using one of the flash devices. According to an embodiment of the flash device, the flash device further includes at least one optical system disposed in front of the illumination unit to provide a zoom function. According to an embodiment of the flash device 'the flash device further uses a control flash' which controls the flash to be activated to capture external data. For example, this is advantageous when photographing in a dark environment. In accordance with an embodiment of the flash unit, the control flash is a preview version of one of the combined predetermined illuminations of the illumination unit having a reduced power, a different color, and a different duration. That is, a test version of a subsequent flash having, for example, a predetermined desired light effect (ie, a joint predetermined illumination of the illumination units) is used to illuminate the scene such that the captured data (ie, test image) can be analyzed Control data for optimizing this subsequent flash is also available. According to the flash device of an embodiment, the plurality of illumination units are arranged in a rectangular array or a circular array. The illumination units can be configured to H-turn I as would be understood by those skilled in the art, and any other suitable configuration of such illumination units is suitable for use in the mouth of the invention 159452.doc 201229645. The flash unit can further include a scanning member, in which case the plurality of illumination units configured in a row are coupled to the scanning member to provide illumination of a two-dimensional surface. Further, the light sources may be solid state light sources (SSL). According to an embodiment of the flash device, the light sources are provided as at least one of visible color, infrared light and ultraviolet light. In accordance with an embodiment of a flash unit, the illumination units are configured to provide target illumination that covers different illumination angles. That is, the illumination units are configured such that illumination is provided that covers different angles of the target and corresponds to, for example, the field of view of a camera. This can also include the field of view of different zoom settings. According to an embodiment of the flash unit, the illumination unit is for providing a laser scanning device of a different illumination angle. According to an embodiment of the flash device, the light source is a light emitting diode. These and other aspects, features, and advantages of the present invention will be apparent from the description of the embodiments described herein.

Pulp lamp. For illustrative purposes, the number of illumination units selected in this exemplary embodiment is 25. However, for camera applications and the use of led as a light source, a typical number of selected illumination units is between 4 and 64. Alternatively, in the flash device of the embodiments in which the optical member is not necessarily required, the optical member may be omitted. Further, the optical member and the corresponding light source can be integrated into a single illumination unit. In a flash unit of an embodiment, the light sources are selected such that the light unit matrix comprises at least two light sources of different colors. For example, the flash device can be configured with a light source for providing light in the visible, infrared, or ultraviolet spectrum. The illumination unit matrix 12 is configured here as a plurality of illumination units 121 of a rectangular array, but may alternatively comprise illumination units configured in a circular array, or even a one-dimensional array of illumination units, respectively This is illustrated in Figures 2a and 2b. The latter is preferably configured with a scanning member (not shown) such as a moving mirror, thereby allowing a single column of light sources to provide two-dimensional sequential illumination of a target. As mentioned above, other configurations of such illumination units are also applicable depending on the application. For continued reference to the embodiment of FIG. 1, each illumination unit 121 is coupled to a control unit UGE including a driver 112 and an arithmetic unit 11! The drive 159452.doc 201229645 actuator 112 is configured to be based on the processing unit The control data CD provided by the camera drives each of the illumination units 121. In the flash unit of embodiments, driving the illumination unit can include driving the light source (e.g., with respect to intensity and color) and controlling the optical member (e.g., with respect to focusing output light and controlling the direction of the output light). The processing unit 111 can include a microprocessor, a microcontroller, a programmable digital signal processor, or another programmable device. The control component 110 is adapted to receive an external data ED, wherein the external data is received in the processing unit 111, and based on the external data ED and a computer executable code (the code is usually stored in a control component) The memory includes instructions for how to analyze and process the extracted external data. The processing unit 111 derives the control data CD required by the driver 112 in response to the external data ED to individually control the illumination unit matrix 12〇. Each of the illumination units 121 in the middle. As will be readily appreciated by those skilled in the art, the flash unit further includes a power circuit, a housing, and a memory unit associated with the control member (i.e., the processing unit). However, in order to simplify the description of the inventive concept, such components are omitted in the drawings and the description. Here, the flash unit 100 is coupled to a camera 5 which is alternatively connectable or integrated into a security device or integrated into a camera. The camera 50 includes an image sensor matrix 51 (which is a ccd). The image sensor matrix 51 includes a maximum number of exposable cells for obtaining one of the target images (n. Obtaining information about a sub-portion corresponding to one of the targets (scene). Others within the scope of the present invention 159452.doc •10· 201229645 Suitable image sensor systems are, for example, based on complementary metal oxide semiconductor (CMOS) Image sensor. When the camera 50 is aimed at a target (ie, a scene), the flash device 100 is configured to capture the captured image data from the image sensor matrix 51, thereby capturing the target Associated external data ED. Alternatively, in addition to the image sensor, an automatic focus member, a zoom position sensor, an automatic illumination s ten component, a distance meter or a mobile sensor may be used. The external data. The different external sources are adapted to provide different external data associated with the target. The control data CD is calculated from the external data ED according to the functionality which will be further explained below by way of example. Referring now to FIG. 3, FIG. 3 is a schematic top plan view of one of the illumination unit matrices 12 of the flash unit of the embodiment, which is illustrated by reference to FIG. 3, which includes 25 illumination units 121, Therein, five illumination units are visible in Fig. 3: 121 & to 12b. Each illumination unit 121 & 121e is configured to provide a predetermined illumination 1A for one of the target regions AE in response to the individual control data CDae. E ^ thus individually illuminating each of the sub-areas AE, and controlling the illumination IA_E «for example, intensity, focus, color, etc. «light generated by the flash (ie, illumination unit matrix 12A) is subsequently targeted by the target Reflecting, and finally, when reaching the photographic lens of the image capturing member of the camera 5, the square of the distance of the light from the target is inversely proportional to β. When the scene is used to measure various objects of the scene by the autofocus mechanism of the camera 50 ( That is, when the distance of the sub-area Α-Ε), the output power from the output light of the flash is proportionally adjusted by the square of the distance for the direction corresponding to the various objects in the target. One of the targets is obtained on the image sensor matrix 5丨 I59452.doc 11 201229645 Average, more natural representation. For photographic applications, it is advantageous to use a flash device to illuminate a sub-area of a target that is particularly important for the photo and thereby enhance the target The visibility of such sub-areas. At the same time, the sub-areas of the main target in the photo that are not to be highlighted (ie blackened or at least darkened) are excluded. For example, the pair-target area 10 will be illustrated as in FIG. There is one case in which one person takes a picture as an instance. The entire target surface area is represented by the set sub-area Α_κ in Fig. 4. Here, the main target is a person, and to identify the sub-area to be illuminated (ie, the set sub-area) DH), external data can be manipulated from the auto focus and/or auto illuminometer settings of the camera image sensor (not shown). The illumination from the flash unit is selected to primarily illuminate the object that the camera is focusing on and does not provide any illumination or provide less illumination to areas that are further off focus or off focus. Alternatively, a sub-area to be illuminated is determined by analyzing the image sensor matrix 51 to provide a test image. The test image analysis for the purpose of testing the person in the image can be found by: face preparation in the test image, contrast measurement in the test image, smile measurement in the test image, the test The mobile pre-measurement in the image (by manually selecting a number of phase users using the image on the camera screen; or any other suitable analysis of the second area (4), the item (4) can be: and in this case the target 1〇The main part of the photo that is interested in lighting 0 ” 2 photography (for example) can be applied to one scene of a room - the opposite method. The external principle is provided by the T:::A image sensor matrix 51 - test image) The sub-area of the target 10 is naturally illuminated (ie, 159452.doc •] 2-201229645 is darker in the test image. Therefore the driver of the flash unit is set so that it is used to provide illumination to be detected in the test. Compared with the illumination unit of the sub-area of the target in the image, the illumination unit for providing the dark sub-area detected by the illumination provides higher intensity output light, thereby requiring sub-area reception of additional illumination. Illumination from the flash unit without the risk of an area of transitional exposure in the photograph. According to an embodiment of the flash unit, the test image is analyzed to detect vignetting caused by, for example, an imaging lens, ie, the processing unit is configured The control data calculated therein provides a higher intensity illumination for sub-regions that are determined to have a target of under-illumination based on the extracted external data associated with the target, thereby providing adjustment (eg, vignetting of the imaging lens) Adjusted illumination. In an alternative embodiment, the test image is analyzed with respect to color content. In response to the color in the test image of the scene, the control data is configured such that the predetermined illumination has an adjusted color shift and/or color temperature. In view of this, the unnatural color of the existing artificial light can be compensated for by mixing the light of an appropriate color with the existing artificial light instead of replacing the existing artificial light with a flash lamp as in the case of a conventional flash. In the flash device of the embodiments, 'when capturing the test image or relying on light as described in the foregoing examples In the case of his external data, a control flash can be used. According to the flash device of an embodiment, the movement measurement using a motion sensor is utilized to analyze the target (where the movement triggers the flash illumination moving area) or other image/sensor Processing information. This further facilitates detection of a moving target, for example, in a surveillance system or security system, and then highlights the moving target by a flash device in accordance with the teachings of the present invention. 159452.doc -13- 201229645 A flash unit of the embodiment, wherein a sub-area of a target area to be illuminated is selected based on a contrast difference and/or a color difference in the external data.

The focal plane shutter 6 is disposed directly in front of the image plane, here directly in front of the image sensor array 5, i.e., between the image sensor matrix 51 and the optical system 7A. The movable aperture 61 determines which portion of the image sensor will be active while the remaining portion of the focal plane shutter closes the remainder of the image sensor matrix 51. By averaging the width and/or position of the illumination sub-area of a target 80 with the width of the aperture and / 159452.doc •14·201229645 or the position of the aperture 61, an advantageous effect is achieved, meaning even in the most The flash device can also be used at the door speed because all portions of the image sensor matrix 51 receive light generated by the flash device. In the case of a conventional electronic flash combined with a focal plane shutter, the shortest exposure time is also It is called the exposure time of the shutter speed, and there is an instant in which the shutter is completely open. The conventional flash is triggered at this instant. The external data for determining the driving data for the flash units 121 (for example) From the active portion of the δ hai imaging sensor matrix. As explained above, other sources from which the external data is retrieved may be used. However, in these embodiments, the control f is then Preferably, which portions of the imaging sensor matrix are actively combined at a certain instant (ie, combined with the image captured by the imaging sensor matrix at that instant), preferably The control data is retrieved from the external data. Further, the predetermined illumination is an embodiment of a flash device configured to provide one of at least one predetermined sub-area of the target. The sequence and the imaging sensor One of the active imaging sub-regions of the matrix 51 is moved in line synchronization ' or is located in front of the imaging sensor 51 by the movable aperture 61. According to one embodiment of the flash device, the illumination units are configured to be connected An optical member that produces a wide beam of light when the entire illumination unit is turned on. When only the central illumination unit is turned on, a narrower beam is generated, thereby concentrating the light on a smaller sub-region of the target. Therefore, 'there is no mechanical In the case of movement, a zoom flash can be manufactured, the beam width of the zoom flash is changed according to the zoom position of the camera lens. 159452.doc -15- 201229645 According to the flash unit of the embodiment, the illumination unit is configured to provide different coverage Illumination of the target of the illumination angle.
