Abstract: This document describes various apparatuses and techniques for rapid synchronized lighting and shuttering. These apparatuses and techniques are capable of capturing two images, where one of the images integrates multiple exposures during which an image area is illuminated by a light source and another of the images integrates multiple exposures during which the image is not illuminated by the light source. The image area can be illuminated by rapidly flashing the image area with the light source and synchronizing a shutter to permit one image sensor to capture an image when the image area is illuminated and another image sensor to capture the image area when the image area is not illuminated. These two images can be captured concurrently or nearly concurrently, thereby reducing or eliminating motion artifacts. Further, these apparatuses and techniques may do so with slow and relatively low-cost cameras and relatively low computational costs.

Which correction pixel slope to be used is determined based on whether a sample image pixel value is higher or lower than a threshold value.

Abstract: When capturing images of a subject with an imaging device that uses a CMOS image sensor, a white band-shaped artifact appears in the imaging signal due to the influence of a rolling shutter operation performed when an external flash has been emitted. Manipulating or removing images in which such an artifact appears requires specifying the frames in which the artifact appears.

These frame difference values are compared with a reference value, and it is determined that the influence of an external flash is present if a portion of interest with high values is continuous for one frame period.

Abstract: Multi-spectral imaging technique embodiments are presented which involve an active imaging approach that uses wide band illumination of known spectral distributions to obtain multi-spectral reflectance information in the presence of unknown ambient illumination. In general, a reflectance spectral distribution of a captured scene is computed by selecting a number of different illumination spectra and capturing multiple images of the scene. Each of these images is captured when the scene is illuminated by a different one of the selected illumination spectra in addition to the ambient light. The reflectance spectral distribution of the scene is computed for each pixel location based on the relative response between pairs of the radiometric responses of the corresponding pixels in the captured images, given a set of parameters including the added illumination spectra used to capture each of the images and the response function and spectral sensitivity of the camera used to capture the images.

Abstract: A method of increasing signal-to-noise ratio of a distance-measuring device includes a light-emitting component emitting a detecting light to a measured object during an emitting period for generating a reflected light, a delay period after the light-emitting component emitting the detecting light, a light-sensing component sensing the energy of the reflected light to generate a light-sensing signal, and obtaining a measured distance between the distance-measuring device and the measured object according to the energy of the detecting light and the light-sensing signal. Since the measured distance is longer than a predetermined shortest measured distance, the method can accordingly calculate a proper delay period for ensuring that the reflected light reaches the light-sensing component after the delay period. In this way, the light-sensing component does not sense the background light during the delay period, so that the signal-to-noise ratio of the light-sensing signal is improved.
