Abstract
A method for reading a data signal emitted by an active pixel in a sensor having a plurality of addressable pixels, comprising the steps of (a) grouping the plurality of pixels into at least two groups each having a fraction of the plurality of addressable pixels, (b) identifying an active group of addressable pixels in which the active pixel is located, (c) providing a reading circuit for the active group of addressable pixels, and (d) reading a magnitude of the data signal in respect of each pixel in the active group of addressable pixels so as to identify the active pixel. A system uses such a method for reading a data signal emitted by an active pixel in a sensor module having a plurality of addressable pixels arranged into at least two groups, and comprises an identifying circuit commonly coupled to each group of pixels and responsive to the data signal for identifying an active group containing the active pixel without identifying the active pixel itself. A reading circuit is responsively coupled to the identifying circuit for reading a magnitude of the data signal in respect of each pixel in the active group, so as to identify the active pixel.
