  • Patent number: 10715750
    Abstract: In dynamic vision sensor (DVS) or change detection sensors, the chip or sensor is configured to control or modulate the event rate. For example, this control can be used to keep the event rate close to a desired rate or within desired bounds. Adapting the configuration of the sensor to the scene by changing the ON-event and/or the OFF-event thresholds, allows having necessary amount of data, but not much more than necessary, such that the overall system gets as much information about its state as possible.

  • Patent number: 10652489
    Abstract: According to the present invention there is provided a vision sensor comprising, an array of pixels comprising rows and columns of pixels, wherein each pixel in the array comprises, a photosensor which is configured to output a current proportional to the intensity of light which is incident on the photosensor; a current source which is configured such that it can output a current which has a constant current level which is equal to the current level of the current output by the photosensor at a selected first instant in time, and can maintain that constant current level even if the level of the current output from the photosensor changes after said selected first instant in time; an integrator which is configured to integrate the difference between the level of current output by the current source and the level of current output by the photosensor, after the selected first instant in time; wherein the vision sensor further comprises a counter which can measure time, wherein the counter is configured such tha

  • Patent number: 10602083
    Abstract: In an image sensor, some pixels in an array contain a sampling circuit to sample the light intensity and a capacitor to store an analog value representing the intensity at that pixel. Alternatively, a group of pixel circuits will be equipped with such sampling and capacitor circuits. This allows simple redundancy-reducing computations with a relatively simple pixel architecture.

  • Patent number: 10498977
    Abstract: According to the present invention there is provided a vision sensor comprising, an array of pixels (101) comprising rows and columns of pixels, wherein each pixel has an address assigned thereto which represents the position of the pixel in the array, wherein each pixel in the array of pixels comprises a photodiode (103) which can receive light, and which can output current having an amplitude proportional to the intensity of the received light; a photoreceptor circuit (104) which is electronically connected to the photodiode, and which is configured to convert current which it receives from the photodiode into a voltage; a first storage capacitor (105), and at least a first switch which (106) is positioned between the first storage capacitor and an output of the photoreceptor circuit, wherein the first switch can be selectively closed to electronically connect the output of the photoreceptor circuit to the first storage capacitor, or selectively opened to electronically disconnect the output of the photorec
