    摘要: A device for generating a photometric stereo image and a color image of an object which is moved at a predetermined relative speed relative to the device. The device includes a lighting area and a lighting arrangement which is oriented to the lighting area. The lighting arrangement cyclically emits a lighting sequence in the lighting area. The lighting sequence has at least four lighting pulses each of which have a wavelength range and a lighting direction. At least three of the at least four lighting pulses have a different wavelength range, and at least two of the at least four lighting pulses have a different lighting direction and a same wavelength range.

    摘要: An electronic device (100) and a method for controlling the electronic device (100) are provided. The electronic device (100) includes a time-of-flight (TOF) module 20, a color camera 30, a monochrome camera (40), and a processor (10). The TOF module (20) is configured to capture a depth image of a subject. The color camera (30) is configured to capture a color image of the subject. The monochrome camera (40) is configured to capture a monochrome image of the subject. The processor (10) is configured to obtain a current brightness of ambient light in real time, and to construct a three-dimensional image of the subject according to the depth image, the color image, and the monochrome image when the current brightness is less than a first threshold.

    摘要: Systems, methods, and devices for fluorescence imaging with a minimal area image sensor are disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation, wherein the pixel array comprises active pixels and optical black pixels. The system includes a black clamp circuit providing offset control for data generated by the pixel array and a controller comprising a processor in electrical communication with the image sensor and the emitter. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises electromagnetic radiation having a wavelength from about 795 nm to about 815 nm.
