The apparatus includes a transparent display having multiple liquid crystal display (LCD) layers. The apparatus includes an image capture module that interfaces with a camera to capture multiple images of a target object. The apparatus includes an image processing module that identifies a bright spot in first and second images, identifies the target object in the first and second images proximate to the bright spot, and modifies at least one of first and second images to diminish the bright spot and to emphasize the target object. The apparatus includes an image display module that interfaces with the transparent display member to display the first image with the first LCD layer and display the second image with the second LCD layer after modifying at least one of the first and second images. ## Claims ### Claim 1 An apparatus, comprising: a transparent display member having a compound liquid crystal display (LCD), the compound LCD having multiple independent LCDs arranged in overlapping layers, including a first layer having a first LCD and a second layer having a second LCD; an image capture module that captures multiple images of a target object, including a first image of the target object and a second image of the target object; an image processing module that: identifies a bright spot in the first and second images, identifies the target object in the first and second images proximate to the bright spot, modifies the first image to diminish the bright spot, and modifies the second image to emphasize the target object, and an image display module that interfaces with the transparent display member to display the modified first image using the first LCD and display the modified second image using the second LCD. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the transparent display member is embodied as a lens for eyewear. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the transparent display member is embodied as a windshield for a vehicle. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the target object comprises at least one of a traffic signal, a road sign, a vehicle, a pedestrian, and an animal, and wherein the bright spot comprises at least one of a bright light and sun glare. ### Claim 5 (depends on 1) The apparatus of claim 1, further comprising a structural frame member, wherein the transparent display member is mounted to the structural frame member. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the image capture module interfaces with the camera to capture the first image of the target object with a first set of parameters, and wherein the image capture module interfaces with the camera to capture the second image of the target object with a second set of parameters that are different than the first set of parameters, wherein the first and second set of parameters include one or more different filter settings, different fields of view, different perspectives, different exposure settings, different aperture settings, and different ISO settings. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein modifying the first image comprises the image processing module applying a histogram to the first image to diminish an intensity of the bright spot. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the image processing module applies the histogram to one or more colors in the first image to diminish the bright spot, and wherein the one or more colors comprise one or more of red, green, blue, cyan, magenta, yellow, and black. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein modifying the first image to diminish the bright spot comprises the image processing module darkening or blocking the bright spot. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein modifying the first image to diminish the bright spot comprises the
