an image processing device configured to generate, based on the video data output from the interface, first and second video images; and an output device configured to output the first and second video images from the first and second external lamps, respectively, wherein the video data has a horizontal resolution equal to a sum of a first horizontal resolution of the first video image and a second horizontal resolution of the second video image. ### Claim 2 (depends on 1) The image output device of claim 1, wherein: the video data includes color data, and the image processing device is configured to generate, based on the color data, the first and second video images. ### Claim 3 (depends on 2) The image output device of claim 2, wherein: the color data includes first color data, second color data, and third color data, and the image processing device is configured to: generate the first video image based on the first color data; and generate the second video image based on the second or third color data. ### Claim 4 (depends on 3) The image output device of claim 3, wherein: the output device includes first and second output devices, the first output device is configured to output the first video image, and the second output device is configured to output the second video image. ### Claim 5 (depends on 1) The image output device of claim 1, wherein the image processing device includes a serializer. ### Claim 6 (depends on 1) The image output device of claim 1, wherein the first video image and the second video image have a common resolution. ### Claim 7 (depends on 1) The image output device of claim 1, wherein a frequency of the video data is a half of a frequency of the first video image and the second video image. ### Claim 8 (depends on 1) The image output device of claim 1, wherein: the output device includes a first output device and a second output device, the first output device is configured to output the first video image, and the second output device is configured to output the second video image. ### Claim 9 A method for outputting an image from first and second external lamps of a vehicle, comprising: outputting video data; generating, based on the video data, first and second video images; and outputting the first and second video images from the first and second external lamps, respectively, wherein the video data has a horizontal resolution equal to a sum of a first horizontal resolution of the first video image and a second horizontal resolution of the second video image. ### Claim 10 (depends on 9) The method of claim 9, wherein: the video data includes first color data, second color data, and third color data, and generating the first video image and the second video image based on the video data includes: generating the first video image based on the first color data; and generating the second video image based on the second or third color data. ### Claim 11 (depends on 9) The method of claim 9, wherein generating the first and second video images includes generating the first and second video images having a common resolution.
