Abstract
A readout arrangement for an image sensor is configured to receive from a plurality of column leads of the image sensor in parallel a plurality of image sensor analog signals describing in an analog manner brightness values detected by the image sensor. The readout arrangement is configured to select which subset of a plurality of analog values represented by the image sensor analog signals or based on the image sensor analog signals is to be stored in an analog memory for further processing, and to cause storage of the selected analog values in the analog memory, or to store the selected analog values in the analog memory.
Claims29
A readout arrangement for an image sensor,
- wherein the readout arrangement is configured to receive from a plurality of column leads of the image sensor in parallel a plurality of image sensor analog signals describing in an analog manner brightness values detected by the image sensor, and
- wherein the readout arrangement is configured to select which subset of a plurality of analog values represented by the image sensor analog signals or based on the image sensor analog signals is to be stored in an analog memory for further processing, and to cause storage of the selected analog values in the analog memory, or to store the selected analog values in the analog memory,
- wherein the readout arrangement is configured to, based on an evaluation of the image sensor analog signals, decide which subset of a plurality of analog values represented by the image sensor analog signals or based on the image sensor analog signals is to be stored in the analog memory for further processing.
A method for reading out an image sensor,
- wherein the method comprises parallelly receiving from a plurality of column leads of the image sensor a plurality of image sensor analog signals describing in an analog manner brightness values detected by the image sensor, and
- wherein the method comprises selecting which subset of a plurality of analog values represented by the image sensor analog signals or based on the image sensor analog signals is stored in an analog memory for further processing,
- wherein, based on an evaluation of the image sensor analog signals, it is decided which subset of a plurality of analog values represented by the image sensor analog signals or based on the image sensor analog signals is to be stored in an analog memory for further processing;
- and
- wherein the method comprises storing the selected analog values in the analog memory.
A readout arrangement for an image sensor,
- wherein the readout arrangement is configured to receive from a plurality of column leads of the image sensor in parallel a plurality of image sensor analog signals describing in an analog manner brightness values detected by the image sensor, and
- wherein the readout arrangement is configured to vary an assignment between an image column and columns of an analog memory in which analog values belonging to the image column are stored so that analog values belonging to an image column are stored in different memory columns of the analog memory, and such that analog values describing a line running diagonally across the image sensor are stored in a rectangular memory region of the analog memory.
