摘要： A depth camera assembly (DCA) includes a direct time of flight system for determining depth information for a local area. The DCA includes an illumination source, a camera, and a controller. In some embodiments, the controller uses previous image frames to determine confidence measurements, and selectively adjusts a number of pulses from the illuminator in a subsequent frame based on the determined confidence values. In some embodiments, the sensor uses autonomous gating, and the depth system includes a depth recovery pipeline which provide depth map estimates from the autonomous gated measurements.

摘要： An imaging apparatus according to an embodiment includes: an imaging unit (10) having a pixel region in which a plurality of pixels is arranged; a readout controller (11) that controls readout of pixel signals from pixels included in the pixel region; a unit-of-readout controller (123) that controls a unit of readout that is set as a part of the pixel region and for which the readout controller performs the readout; and a recognition unit (14) that has learned training data for each of the units of readout. The recognition unit performs a recognition process on the pixel signal for each of the units of readout, and outputs a recognition result which is a result of the recognition process.

摘要： To reduce a circuit scale in a solid-state image sensor that detects an address event. The solid-state image sensor includes a pixel array unit and a drive circuit. In the solid-state image sensor, in the pixel array unit, a logarithmic response pixel that outputs an analog signal proportional to a logarithmic value of an incident light amount and a detection pixel that detects whether or not a change amount of the incident light amount has exceeded a predetermined threshold and outputs a detection signal indicating a detection result are arrayed. Furthermore, in the solid-state image sensor, the drive circuit drives the logarithmic response pixel and the detection pixel to output the analog signal and the detection signal.

摘要： An event sensing system includes a pixel array including a plurality of event driven pixel circuits configured to be illuminated by incident light. The event driven pixel circuits are configured to generate an event current in response to a detection of an event in the incident light. Output signals of a row of the pixel array are configured to be read out from the row of the pixel array to a line buffer in response to the detection of the event in the incident light. A random number generator is configured to randomly generate a filtering mask. A mask circuit is the output signals of the row of the pixel array from the line buffer and the filtering mask from the random number generator to filter the output signals of the row of the pixel array in response to the filtering mask.

摘要： Only a necessary region is imaged on the basis of a result of interleaving imaging. An imaging apparatus includes an imaging element, an analog-to-digital converter, and a conversion control unit. The imaging element generates analog signals of a plurality of pixels for a plurality of pixel blocks each including a plurality of pixels. The analog-to-digital converter performs analog-to-digital conversion processing for converting an analog signal into a digital signal. The conversion control unit controls the analog-to-digital conversion processing of a plurality of pixels included in a predetermined pixel block according to a difference between a digital signal of a representative pixel in the predetermined pixel block in the plurality of pixel blocks and a predetermined reference value.

摘要： The invention relates to a method for online quality control of decorative prints on substrate materials, including similarity comparisons of actual and target images and adjusting decorative prints if deviations of color values are detected. The method may include the steps of: a) producing a hyperspectral digital image of a print decoration; b) calibrating the print decoration via a hyperspectral digital image; c) producing and storing a digital target image of the print decoration; d) creating a first print decoration on a first substrate material; e) producing and storing a digital actual image of the printed decoration on the first substrate material; f) determining color deviations between the digital target image and the digital actual image via a computer program; and g) printing on at least one side of substrate materials so as to form a decorative layer. The invention also relates to a device for carrying out the method.

摘要： An image-sensing system for the efficient detection of defective pixels is shown. An arithmetic logic unit (ALU) determines a defective pixel candidate of an image sensor based on the first frame captured by the image sensor, performs a lower-part comparison on the defective pixel candidate based on the first frame, and performs an upper-part comparison on the defective pixel candidate based on the second frame captured by the image sensor. The defective pixel candidate is confirmed to be defective based on the first frame as well as the second frame. Only limited pixel data is buffered for the defective pixel detection.
