  • Patent number: 11460557
    Abstract: An apparatus for distance measurement, having one or several optical detector modules and a readout module is provided. The optical detector modules each have a plurality of optical detector elements having one or several optical detectors and a counter indicating a count value, the optical detector elements each being in an active state or an inactive state. Each optical detector module has a timer element configured to determine a current time value and configured to continuously update the current time value, and a memory element for storing a plurality of time values stored.

  • Patent number: 7271937
    Abstract: In a method for imaging, a plurality of image sensor elements is used, which generate different output signal values when using different exposure times. For each image sensor element, an image signal value is generated by generating a first output signal value when using a first exposure time and an associated second output signal value using a second exposure time. If the first output signal value does not exceed a threshold value associated thereto, the image signal value is calculated using a first calculating rule on the basis of the first output signal value. If the first output signal value exceeds the threshold value, the image signal value is calculated using at least a second calculating rule on the basis of at least the second output signal value.

  • Publication number: 20040047012
    Abstract: In a method for imaging, a plurality of image sensor elements (12) is used, which generate different output signal values when using different exposure times. For each image sensor element, an image signal value is generated by generating a first output signal value (y1(x)) when using a first exposure time (Tint,long) and an associated second output signal value (y2(x)) when using a second exposure time (Tint,short). If the first output signal value does not exceed a threshold value (yo) associated thereto, the image signal value (y(x)) is calculated using a first calculating rule on the basis of the first output signal value (y1(x)). If the first output signal value exceeds the threshold value (yo), the image signal value (y(x)) is calculated using at least a second calculating rule on the basis of at least the second output signal value (y2(x)).

  • Patent number: 6396048
    Abstract: An optical detector has at least one image sensor element that generates an image sensor element output signal according to the illumination incident on the element. A readout amplifier for the one or each image sensor element is switchable between a plurality of amplification stages for amplifying the respective image sensor element output signal. An amplification switch is provided for comparing the image sensor element output signal with at least one given threshold value before the signal is amplified by the readout amplifier and for switching between the amplification stages of the readout amplifier depending on the result of the comparison. The optical detector has a first output signal indicating the amplified image sensor element output signal and a second output signal indicating the amplification stage to which the amplifier is switched.
