Patent ID: 8511559

Claim:
An apparatus for reading targets in succession, comprising: a housing; a window supported by the housing; a solid-state imager supported by the housing and having an array of light sensors looking at a field of view that extends through the window to the targets, and operative for capturing return light from the targets to be read; a controller for controlling the imager to operate at a frame rate to acquire images of the targets over successive frames; a memory accessible to the controller for storing the acquired images, the controller being operative for processing all of the stored images, and for processing at least one of the stored images over an extended time period greater than one of the frames; and wherein the controller controls the imager to operate in a batch mode in which entry of a first one of the targets into the field of view serves as a start capture event of a reading session, and in which exit of a last one of the targets from the field of view serves as an end capture event of the reading session; wherein the memory stores the acquired images of the targets during the reading session; and wherein the controller processes the stored images during an idle session following the reading session.
