摘要： A solid-state imaging element according to the present disclosure includes a plurality of first photoelectric conversion elements, a plurality of second photoelectric conversion elements, a plurality of current-voltage conversion circuits (320 and 320A), and a plurality of address event detection circuits (231 and 231A). The plurality of first photoelectric conversion elements is arranged side by side in a first region. The plurality of second photoelectric conversion elements is arranged side by side in a second region adjacent to the first region. The plurality of current-voltage conversion circuits (320 and 320A) each converts currents output from the plurality of first photoelectric conversion elements or the plurality of second photoelectric conversion elements into voltages. The plurality of address event detection circuits (231 and 231A) each detects a change in the voltages output from the plurality of current-voltage conversion circuits (320 and 320A). At least either the current-voltage conversion circuits (320A) or the address event detection circuits (231A) connected to the second photoelectric conversion elements prevent output of signals based on the currents output from the second photoelectric conversion elements.

摘要： To improve sensitivity, reduce dark current, and reduce power consumption.
An imaging device includes a photoelectric conversion unit including a plurality of photoelectric conversion elements each of which photoelectrically converts incident light to generate an electric signal, a detector configured to output a detection signal indicating whether or not an amount of change in the electric signal of each of the plurality of photoelectric conversion elements exceeds a predetermined threshold value, a pixel signal generation unit configured to generate a pixel signal on the basis of the electric signal, a transfer controller configured to perform control to transfer the electric signal to the pixel signal generation unit, and an analog-to-digital converter configured to convert the pixel signal into a digital signal. The low-potential-side reference potential of the photoelectric conversion unit, the low-potential-side reference potential of the detector, the low-potential-side reference potential of the pixel signal generation unit, the low-potential-side reference potential of the analog-to-digital converter, and the off-potential of the transfer controller include three or more potentials having different potential levels.

摘要： The present disclosure provides a pixel collection circuit and an image sensor. The image collection circuit includes: a movement detection module configured to detect a change in a light intensity in a field of view, and generate a pixel triggering signal when the change in the light intensity exceeds a predetermined threshold so as to indicate the pixel collection circuit to be in a triggered state; and a time signal generation module coupled to the movement detection module and configured to generate a time signal upon the receipt of the pixel triggering signal, the time signal being used to represent time information about a time point at which the pixel collection circuit is triggered. The movement detection module and the time signal generation module are coupled to a reading unit, so that the reading unit scans the pixel collection circuit to output the time information about the pixel collection circuit.

摘要： A solid-state image capturing system (1) includes a solid-state image capturing device (100) and an information processing device (200). The solid-state image capturing device (100) includes a first DNN processing unit (130) that executes, on image data, a part of a DNN algorithm by a first DNN to generate a first result. The information processing device (200) includes a second DNN processing unit (230) that executes, on the first result acquired from the solid-state image capturing device, remaining of the DNN algorithm by a second DNN to generate a second result.

摘要： The present invention relates to a method (30) and an image capturing device (10) for reconstructing a color image (40, 50, 60) from raw image data depicting a scene (20), the raw image data produced by the image capturing device (10) comprising at least one image sensor (102). The method (30) comprising: identifying (S302) at least one region of interest in the raw image data; and reconstructing (S304) the color image (40, 50, 60) by: demosaicing (S306) the at least one region of interest in the raw image data using a first demosaic algorithm, and demosaicing (S308) regions outside the at least one region of interest in the raw image data using a second demosaic algorithm; and wherein the first demosaic algorithm is configured for enhancing high spatial frequencies in raw image data to a larger extent compared to the second demosaic algorithm.
