The present technology relates to an information processing apparatus and method that enable characteristics of a projection image to be varied locally. An information processing apparatus according to the present technology controls a first projection unit to project a first image onto an image projection surface and controls a second projection unit to project a second image in an attention area as a predetermined partial area of the first image projected onto the image projection surface by the first projection unit. The present technology is applicable to electronic apparatuses including a projector function or both the projector function and a camera function, a computer that controls the electronic apparatuses, and the like.

An image drawing apparatus includes a light source unit that outputs a laser light, a sensor that measures an index regarding brightness of the laser light, a scanner that reflects and scans the laser light, and an image processor that controls the light source unit, outputs the laser light to a drawing area narrower than a scanning area of the scanner so that an image based on image data that has been input is drawn, outputting an adjustment laser light to adjust the brightness of the laser light to an outside of the drawing area, stops the output of the adjustment laser light when a period (e.g., variable) until the time the output of the adjustment laser light becomes stable is passed after the output of the adjustment laser light is started, and adjusts the laser light brightness based on the index regarding the adjustment laser light brightness.

Apparatus and methods for displaying an image by a rotating structure are provided. The rotating structure can comprise blades of a fan. The fan can be a cooling fan for an electronics device such as an augmented reality display. In some embodiments, the rotating structure comprises light sources that emit light to generate the image. The light sources can comprises light-field emitters. In other embodiments, the rotating structure is illuminated by an external (e.g., non-rotating) light source.

An optical subsystem of a near-eye display system provides for projecting light of a virtual image of image content to an eye location, and provides for collecting light of the virtual image onto an exit pupil on a surface proximate to an outer surface of an eye when at the eye location. A subpupil modulator within an aperture in cooperation with the optical subsystem provides for forming a plurality of subpupils within the exit pupil, and provides for less than all of the light of the virtual image associated with one or more less than all of the plurality of subpupils to be projected to the eye location. In various independent aspects: at least two subpupils overlap by at least 20 percent; and the intensities of the subpupils are individually and independently controlled.
