An example of the present disclosure provides a stereo camera assembly of an object tracking system. The stereo camera assembly comprises a wide-angle lens camera mounted on a mounting structure and a telephoto lens camera mounted on the mounting structure such that a field of view of the telephoto lens camera is at least partially encompassed by a field of view of the wide-angle lens camera.

The present disclosure relates to a projection device, and more particularly, to a projection device including: a projector module configured to provide an image to a screen; and a lens module between a user's eyes and the screen, wherein the project module includes: a display module configured to provide a certain image; and a backlight module configured to provide light to the display module such that the image provided by the display module is projected on the screen, wherein the display module is between the backlight module and the screen, the display module is configured to induce a convergence reaction on the user's eyes such that the image projected on the screen has a convergence distance, and the lens module is configured to induce a focus reaction on the user's eyes and change a focal length of the image reproduced by the display module within a certain range.

Techniques for aligning and stabilizing images generated by an integrated stereo camera pair with images generated by a detached camera are disclosed. A first image is generated using a first stereo camera; a second image is generated using a second stereo camera; and a third image is generated using the detached camera. A first rotation base matrix is computed between the third and first images, and a second rotation base matrix is computed between the third and second images. The third image is aligned to the first image using the first rotation base matrix, and the third image is aligned to the second image using the second rotation base matrix. A first overlaid image is generated by overlaying the third image onto the first image, and a second overlaid image is generated by overlaying the third image onto the second image. The two overlaid images are parallax corrected and displayed.

An electronic mirror system presents circumstances surrounding a moving vehicle by displaying an image presenting the circumstances surrounding the moving vehicle. The electronic mirror system includes an image display and an optical system. The image display displays, every time image data is acquired from an image capturing unit, the image, based on the image data acquired from the image capturing unit, on a display screen. The image capturing unit continuously shoots video presenting the circumstances surrounding the moving vehicle. The optical system condenses, into an eye box, a light beam representing the image displayed on the display screen to make a user, who has a viewpoint inside the eye box, view a virtual image based on the image displayed on the display screen. The display screen is arranged to be tilted with respect to an optical path that leads from the display screen to the optical system (30).

A light projection system including a light source, a light controller optically and/or electrically coupled to the light source to generate a plurality of spatially-separated and independently-modulatable beams of light, and an angular light modulator (ALM) positioned to receive the beams of light and selectively direct the light from each beam into one of a plurality of directions. The light source can include a laser diode array. The light controller can be a spatial light modulator or a processor programmed to control an output of each of the lasers of the laser diode array. The angular light modulator may be a digital micromirror device (DMD). The ALM may be configured to project the images into corresponding diffraction orders of the ALM or the ALM may be configured to continuously scan the images.
