Therefore, if there is an auxiliary camera to help display the dead angle that the driver cannot see, it will be able to reduce the driving. The difficulty. Therefore, in addition to considering the performance of the car and the comfort of the ride, the driver will also carefully purchase a camera that can assist in driving safety to protect his safety and property. Under this trend, car manufacturers or vehicle equipment designers have tried their best to develop various driving safety recorders or auxiliary devices in order to increase the safety of vehicles.

Therefore, at least the digital image 111 generated by the image recorder group u and the luminance histogram Pa generated by the image sensor 12 can be separately transported to the image processing unit 13. In this way, the image processing unit 13 can perform brightness adjustment on the digital image 111 according to the degree histogram 12a to convert the digital image m into a higher-complex-composite image 13a for human eye recognition. The image processing unit 13 is preferably a slab of a field-programmable gate array (FpGA) to receive the number (four) image 111 and the luminance histogram 12a, or may be changed according to other needs of the designer. This field can program the wafer of the gate array to run other basic functions. Furthermore, the multi-lens camera unit 1 further includes an output port 14 and outputs 蟑Μ_ to the image processing unit. Thereby, the composite image 13a converted by the image processing unit 13 can be output to a display 15' via the material 14 for viewing by a user. Therefore, the user can view the screen on which the comparison operation has been performed and the brightness A is increased on the display H 15 . Therefore, with the multi-lens camera i of the present case, the user can still monitor the surrounding environment through the display 15 at night or when the light source is insufficient, thereby further ensuring his own safety. Please refer to FIG. 2 and FIG. 4 together, which are block diagrams of the first embodiment and the second embodiment of the multi-lens camera device 1 of the present invention. In the two embodiments, the image (four) group U preferably has at least two image recording devices ιι, so the image recorder group u can output at least a first digital image uia and a second digital image 111b. The image sensor 12 is disposed between at least two image capturing devices (four) 'so that the image recorder group i! and the image sensor i 2 sense that the face M439960 overlaps. For convenience of explanation, the following description will be exemplified by the image recorder group u having two image recording devices UG. Further, the image processing unit 13 includes a shadow county module 131 and a brightness adjustment module 133, and the image combining module ΐ3ι and the brightness adjustment module 133 are mutually subtracted to transmit data. However, it should be noted that the positions of the image combining module 131 and the brightness adjusting module 133 in the image processing unit A 13 can be interchanged, so that the first embodiment of the multi-lens camera 1 of the present invention is respectively configured. With the second embodiment. In detail, in the first embodiment of the present invention, the first digital image 111a and the second digital image 丨Ub are merged by the image combining module 131 & and then transmitted to the brightness adjusting module 133. In the second embodiment, the first digital image U1a and the second digital image deuteration system are first subjected to brightness adjustment by the brightness adjustment module 133, and then transmitted to the image combining module 131 for performing the merge operation. This is the difference between the first embodiment and the second embodiment. Please refer to Figure 2 first. In the first embodiment, the image combining module 131 is coupled to the two image capturing devices 110 to receive the first digital image U1a and the second digital image liib. Thereafter, the image combining module 131 combines the first digital image 1113 and the second digital image 111 b into a first transition image 132a. Thereby, the field of view recorded by the first transition image 132a is wider than the individual first digital image 丨丨13 or the second digital image 111b, so as to provide a wide viewing angle image. Thereafter, the image merge module 131 transmits the first transition image 丨32a to the brightness adjustment module in for adjustment. The brightness adjustment module 133 uses the histogram equalization method to base the first transition image 132a. The brightness histogram 12a received from the image sensor 12 is displayed 12^ to adjust the brightness to become the composite image core, and then output to the display through the material 14 for display. By the above setting, the user can view the brightness 袪円The composite image 13a has a wider viewing angle. Please refer to circle 3, which is a combination of the first digital image (1) a and the second digital shirt image 1 Ub, and please refer to FIG. 2 and FIG. 3 in detail. The image combining module (3) of the multi-lens camera device 1 combines the first digital material jla and the digital image lm into a transition image. The preferred embodiment of the method is to add a weighting value to the first digit. The image heart and the second digital image (1)b are combined horizontally, wherein the digital image and the second digital image (1)b have overlapping portions of the image due to the position of the image recording device 110. Further, the first The bit image (1) & and the second digital image (1) b image overlap portion has a width L, and if the edge from the beginning of the image overlap is counted as 〇, then the direction of the overlap portion is X, then the combined pixels The weight value is: the weight value of each pixel in the first-digit image (1)a* (Lx/L) + the weight value of each pixel in the second digital image 丄丄丄b* (four). In other words, 'in the image heavy (four) towel, If the image is pure (4) near the first-digital image 111a', the weight of the first-digit image (1) & is greater than the weight of the second digital image (10); if the pixel position is closer to the second digital image nib, then the first The weight of the two-digit image nib is greater than the weight of the first digital image uia. The setting and operation 'is used to generate the first transition image ma. However, the above image is combined only for enumeration. The formula for changing the digital position can be easily changed. The formula of the brightness adjustment module 133 for brightness adjustment is a histogram equalization 13 M439960

That is, the luminance histogram is used as a mapping function to map the first transition image 132. For example, as shown in Table 1, the first transition image must have a pixel brightness of 2, and the luminance histogram ^ is used as a mapping function. A new brightness 45 is generated; the brightness of the other pixel of the first transition image (10) is 3', and the new brightness is 8〇 as the mapping function by the luminance histogram 12a; the brightness of the next pixel of the first transition image 132a is 4, Brightness histogram... The field mapping function corresponds to a new brightness of 13G, and so on. Thereby, each pixel of the first transition image 132a is subjected to luminance conversion, and a composite image i3a is generated. Of course, it will then be displayed on the display 15 via the output port 14 for the user to view.

In the second embodiment, the brightness adjustment module 133 is coupled to at least two image capturing devices 110 and the image sensor 12. Therefore, the brightness adjustment module 133 is adapted to receive the first digital image Uu and the second digital image 111b from the two video recording devices 11 and receive the brightness histogram M439960 12a from the image sensor 12. The brightness adjustment module 133 then uses the histogram equalization method to map the first digital image 11 la and the second digital image 11 lb according to the luminance histogram 12 a to adjust the brightness to a second transition image 132 b and a The third transition image 132c. The brightness adjustment module 133 transmits the second transition image 132b and the third transition image 132c to the image merge module 131. The image merge module 131 combines the second transition image 132b by using the weight value addition and combination method. The third transition image 132c is a composite image 13a. Thereafter, it is displayed on the display 15 via the output port 14. It should be noted that, in the embodiment, the positions of the image merging module 131 and the brightness modulating module 133 are reversed from the first embodiment, so the order of processing the digital image 111 has a difference, but their respective The functions of the image merging module 131 and the brightness modulating module 133 in the first embodiment are not described here. In summary, in the multi-lens camera device disclosed in the present invention, at least two image capturing devices record the environmental scene, and then perform a merge operation to obtain a composite image of a wide viewing angle and transmit it to the display. Help users understand the surrounding environment to solve the problem of visually dead ends. Furthermore, an image sensor with an infrared coupling device can be used to generate a brightness histogram to assist in adjusting the brightness of the digital image to become a composite image. Therefore, if you can provide a composite image of sufficient brightness at night driving or low visibility, there is enough information to provide for identification and judgment. Of course, the multi-lens camera device of this case can also be installed in the car, which will greatly improve the safety of the driver. However, the above is only the preferred embodiment of the case, and it is not intended to limit the scope of the patent 15 M439960.
