摘要： Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each channel of the multi-channel light source (which may be able to produce visible light and/or non-visible light), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the light). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

摘要： A depth pixel of a time-of-flight (ToF) sensor includes a common photogate disposed in a center region of the depth pixel, a plurality of floating diffusion regions disposed in a peripheral region surrounding the center region, a plurality of demodulation transfer gates disposed in the peripheral region, and a plurality of overflow gates disposed in the peripheral region. The demodulation transfer gates transfer a photo charge collected by the common photogate to the plurality of floating diffusion regions. The demodulation transfer gates are symmetric with respect to each of a horizontal line and a vertical line that pass through a center of the depth pixel and are substantially perpendicular to each other. The overflow gates drain the photo charge collected by the common photogate, and are symmetric with respect to each of the horizontal line and the vertical line.

摘要： Various implementations disclosed herein include devices, systems, and methods that generate exposed panoramic image data of an environment. For example, an example process may include obtaining panoramic image data including pixel values corresponding to light received by one or more image capture devices from multiple angles in a physical environment, generating blurred panoramic image data by adjusting the individual pixel values based on values of a subset of other values of the pixel values, selecting an area of the blurred panoramic image data, and determining an exposure for the panoramic image data based on the area of the blurred panoramic image data.

A detection unit includes: a first transistor, a second transistor, a storage capacitor and a photoelectric detection device, and because an active layer of the second transistor is made of amorphous silicon semiconductor materials and an active layer of the first transistor is made of low-temperature poly-silicon semiconductor materials or metallic oxide semiconductor materials, transmission delay of an electric signal generated by the photoelectric detection device may be reduced by controlling conduction and cut-off of the first transistor and controlling conduction and cut-off of the second transistor.

摘要： This disclosure presents a novel smart CMOS imaging sensor and the methods and system for imaging of an object using the smart CMOS imaging sensor. A CMOS-implemented 3D imaging system compromises a wise-pixels-containing imaging sensor and a scanning light point or beam to achieve 3D shape reconstruction, by recording performance of each wise-pixel to the incident light over the period of “valve modulation”. The “valve modulation” is a one-time process of accumulation and release of charges. A frame period comprises multiple valve modulations. In the “frame period”, each wise-pixel will repeat the process that temporarily stores the light intensity, and then release, along with a selection of preferred intensity (e.g. the globally maximum intensity, or the locally maximum intensities, and or the intensities above a certain threshold) during the whole frame period, and the selected intensity and the corresponding time will be exported to the computing units. The selection of the different preferred light intensities is implemented by memory-based, threshold-based, and difference-based approaches, respectively. The obtained maximum intensity and time information can be used to reconstruct 3D geometric information of the surface of the object scanned by moving light source.

摘要： Systems and techniques are described for controlling digital imaging field of view. A device's first image sensor captures a first image based on first light redirected by a light redirection element, and the device's second image sensor captures a second image based on second light redirected by the light redirection element. The device can modify the first image and second image using perspective distortion correction, and can generate a combined image with a large field of view by combining the first image and the second image. The light redirection element can include two prisms that have corners cut and polished to form edges, which can be coupled together and/or colored. A refractive index of the adhesive can be selected to minimize light noise in the combined image. A light-absorbent colorant can coat the interface between the edges of the prisms to minimize light noise in the combined image.
