The integrated photo-sensing detection display substrate includes a base substrate; a plurality of light emitting elements on the base substrate and configured to emit light, a portion of the light being totally reflected by a surface thereby forming totally reflected light; a light shielding layer between the plurality of light, emitting elements and the base substrate configured to block at least a portion of diffusedly reflected light from passing through, the light shielding layer having a light path aperture in the inter-subpixel region allowing at least a portion of the totally reflected light to pass through thereby forming a signal-enriched light beam; a diffraction grating layer configured to at least partially collimate the signal-enriched light beam thereby forming a collimated light beam; and a photosensor configured to detect the collimated light beam.

A disclosed monitoring system includes infrared light sources that illuminate a subject in a sequenced manner and a camera that captures images of the subject during periods in which the subject is illuminated by one of the light sources. The system includes a processor that analyzes captured images to determine a brightness measure of the images, and a controller controls output power of the infrared light sources in response to the brightness measure. In response to the processor detecting a brightness measure below a predetermined brightness threshold, the controller is configured to switch off or reduce an output illumination intensity of one of the infrared light sources. A disclosed method further determines whether an emission source is occluded by modulating an intensity of an electromagnetic emission source, detecting whether the modulation pattern is present in captured images, and determining that the emission source is occluded based on the detected modulation.

An image or a video may include a spherical capture of a scene. A punchout of the image or the video may provide a panoramic view of the scene.

Data of a captured image including a polarized image is acquired (S10), and space information relating to a position and a posture of a subject in a real space and the position and the posture on an imaging plane is acquired using the captured image data (S12). Next, a polarization degree distribution is acquired from a polarized image of a plurality of orientations (S14), and a position of a light source is acquired by specifying an image of a true light source by threshold value determination of the polarization degree (S16). A reflection characteristic is acquired by applying a rendering equation under assumption that luminance of the captured image is already known (S18), and a material suitable therewith is specified as a material of the subject (S20). Processing according to the material is performed to generate output data and output the data (S22).
