The present disclosure provides a device, in particular a multifocal display device. The device includes: a display element configured to generate an image; and a controller configured to control the display element according to at least a first bit sequence provided over a first determined time period and a second bit sequence provided over a second determined time period, in order to generate the image with one or more colors, the bit sequences including for each color a number of bits of different significance. Moreover, the device is configured to generate the first bit sequence from an original bit sequence based on discarding at least one bit of a color and to generate the second bit sequence from the original bit sequence based on discarding at least one other bit of the color.

A scanning projector and method is provided that that uses at least one multi-stripe laser to generate the laser light for the scanned image. Specifically, the multi-stripe laser includes at least a first laser element and a second laser element formed together on a semiconductor die. The first laser element is configured to output a first laser light beam, and the second laser element is configured to output a second laser light beam. At least one scanning mirror is configured to reflect the first laser light beam and the second laser light beam, and a drive circuit is configured to provide an excitation signal to excite motion of the at least one scanning mirror. Specifically, the motion is excited such that the at least one scanning mirror reflects the first laser light beam and the second laser light beam in a raster pattern of scan lines.

A position detection apparatus includes a first irradiation section and a second irradiation section that irradiate an operation surface with detection light, an imaging section that captures an image of the operation surface, and a detection section that detects a pointed position pointed with a pointing element based on the captured image. The first irradiation section is disposed in a position closer to the operation surface than the second irradiation section and emits light having intensity higher than the intensity of the light emitted from the second irradiation section. Instead, the position detection apparatus further includes an adjustment section that adjusts the intensity of the light emitted from at least one of the first irradiation section and the second irradiation section to adjust contrast between the pointing element and the operation surface to a value that exceeds a threshold.

A high resolution photographed image, picked up by a camera device, is projected by using a projector. In a case where there is a magnifying operation of a display image that is projected, image data of the display image that is reduced in accordance with the resolution at the projector side, is not magnified, but the image data of a display region corresponding to the size of a requested magnification ratio in the original photographed image, is reduced, to project a magnified image that is a display image based on the image data.

When a picture displayed on a client device is enlarged, the client device may be configured to insert new pixels between two adjacent pixels in the picture. When actual values of the new pixels are stored on a server, the client device may submit a request to the server for actual values of the new pixels. Responsive to the request, the server may first calculate interpolation values in accordance with the same interpolation algorithm and then calculate a difference value based on the interpolation values and the actual values stored on the server. If the calculated difference value is greater than a threshold value, the server may transmit the actual values for the new pixels to the client device. Otherwise, the server may instruct the client device to calculate the interpolation values.

A device, system and method for content-adaptive resolution-enhancement is provided. A plurality of subframe streams are generated from a video stream, each of the plurality of subframe streams comprising a lower resolution version of the video stream, pixel-shifted from one another. A plurality of output subframe streams are generated from the plurality of subframe streams in a one-to-one relationship by: applying a plurality of video enhancement filters to each of the plurality of subframe streams, each of the plurality of video enhancement filters for enhancing different features of the video stream; and, combining one or more resulting enhanced subframe streams into a respective output subframe stream based on data in one or more regions of the video stream. One or more projectors are controlled to project the plurality of output subframe streams to combine the plurality of output subframe streams into a higher resolution projected video stream.
