Pinhole algorithm
WebOct 30, 2024 · A pinhole camera is a basic camera model without a lens. Light rays pass through the aperture and project an inverted image on the opposite side of the camera. … WebThe pinhole camera is the most basic form of such a modulation imager, but its disadvantage is low throughput, as its small aperture allows through little radiation. Since only a tiny fraction of the light passes through the pinhole, which causes a low signal-to-noise ratio, imaging through pinholes involves unacceptable long exposures.
