METHOD FOR THE OPERATION OF A PHOTOELECTRIC SENSOR ARRAY
First Claim
1. A method for operating a sensor array having a plurality of photoelectric converter elements, wherein each converter element generates a content corresponding to light incident thereon over an exposure time period in which the converter element is exposed to the light, the method comprising:
- arranging the converter elements into at least first and second image regions such that the first image region includes at least one of the converter elements and the second image region includes at least one other of the converter elements;
resetting each converter element at an initial time such that the contents of the converter elements are cleared;
exposing the converter elements to receive light for a first exposure time period after the initial time;
interrupting the exposure of the converter elements to the light for a first interruption time period after the first exposure time period;
reading the content of each converter element in the first image region during the first interruption time period; and
exposing the converter elements to receive the light for a second exposure time period after the first interruption time period;
wherein the exposing, interrupting, and reading steps performed from the beginning of the first exposure time period to the end of the second exposure time period are performed without resetting the converter elements.

Abstract
A method for operating a sensor array of pixels which each generate a content corresponding to light incident thereon over an exposure period includes the following operations. The pixels are arranged into first and second regions and are reset such that the contents are cleared. The pixels are then exposed to receive light for a first exposure period. The exposure is then interrupted during which the content of each pixel in the first region is read. The pixels are then exposed to receive light for a second exposure period. The exposure is then interrupted during which the content of each pixel in the second region is read. The exposing and interrupting are performed without resetting the pixels such that the read content of each first region pixel depends on the first exposure period and the read content of each second region pixel depends on the first and second exposure periods.

11. An assembly comprising:
-
a sensor array having a plurality of photoelectric converter elements, wherein each converter element generates a content corresponding to light incident thereon over an exposure time period in which the converter element is exposed to the light, wherein the converter elements are into at least first and second image regions such that the first image region includes at least one of the converter elements and the second image region includes at least one other of the converter elements; a controller configured to reset each converter element at an initial time such that the contents of the converter elements are cleared; wherein the controller is further configured to, without resetting the converter elements, expose the converter elements to receive light for a first exposure time period after the initial time, interrupt the exposure of the converter elements to the light for a first interruption time period after the first exposure time period, read the content of each converter element in the first image region during the first interruption time period, and expose the converter elements to receive the light for a second exposure time period after the first interruption time period. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
