There is provided a system and method for following and conducting laboratory procedures for preventing errors and fatigue of the user. The system involves input means, such as a microscope, and a camera connected to the input means, while the camera creates images of the input means. A computer is connected to the camera, and it processes the images so that augmented reality glasses which are also connected to the computer, are capable of having those images projected thereon. The computer also has laboratory protocol files installed thereon, and it projects images of the protocols onto the glasses. The projected images do not interfere with a user's natural vision.

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.

A camera system includes a plurality of cameras configured to capture images in different directions. The camera system rotates the plurality of cameras in a predetermined direction. The plurality of cameras are configured such that, even during rotation, one of the cameras captures an image of a preset specific region. The camera system acquires parallax information regarding an object present in the specific region on the basis of a plurality of captured images of the specific region.

A medical image processing apparatus includes an image processor configured to set a cut-out range for each of a medical image for a right eye and a medical image for a left eye, captured respectively by a first imaging device and a second imaging device with a fixed inward angle that is an angle formed by imaging directions, and perform an electronic zoom process of enlarging an image in the cut-out range; and a display controller configured to control display on a display screen of the medical image for the right eye and the medical image for the left eye that have been subjected to the electronic zoom process by the image processor. The image processor sets the cut-out ranges for right and left eyes based on a reference distance corresponding to the inward angle and a subject distance in the first imaging device and the second imaging device.

A lens apparatus includes a first optical system, a second optical system disposed in parallel with the first optical system, and a lens mount attachable to a camera body.
