data may be stored in one tenth second intervals where no movement occurs over the entire second all of the stored data may be used to generate the image for decoding where movement occurs however during the last half of the imaging second the first half second of data may be used to generate the image for decoding here the exposure time and movement would correspond to the first half of the data generating second in another example processor 108 does not acquire an image while the motion of reader 10 is above a certain threshold level of movement referring now to fig4 an exemplary method 140 for selecting an image moment and an exposure time as a function of reader movement is illustrated referring also to fig1 and 2 at block 141 a quantity range of required image data is specified for processor 108 here as known in the art as camera exposure time is increased the quantity of data collected by the reader camera increases the greater the amount of data collected by a camera typically the better the resulting image thus there is typically some optimal quantity of image data that should be collected to generate an image however there is also typically some quantity of data less than the optimal quantity that is usually sufficient for generating an image for decoding purposes here at block 141 both the optimal and sufficient quantities of image data are specified for processor 108 at block 142 an image collecting process is initiated here image collection initiation may comprise.
