Portable encoded information reading terminal configured to acquire images

摘要

An encoded information reading (EIR) terminal can comprise a microprocessor, a memory, an EIR device including a two-dimensional imaging device, a motion sensing device, and a communication interface. The EIR terminal can be configured, responsive to detecting a pre-defined pattern in a first plurality of values received from the motion sensing device, to store in the memory a point of origin equal to a first spatial position of the EIR terminal. The EIR terminal can be further configured, responsive to detecting a user interface command, to determine, based on a second plurality of values received from the motion sensing device, a second spatial position of the EIR terminal relative to the point of origin, and to acquire an image of the object. The EIR terminal can be further configured to determine the image scale factor based on at least the second spatial position.

1. An apparatus comprising:
a motion sensing device; a communication interface; and a processor that:
stores, responsive to detecting a pre-defined pattern in a first plurality of values received from said motion sensing device, in memory a point of origin that corresponds to a first spatial position of said apparatus, determines, responsive to detecting a user interface command and based on a second plurality of values received from said motion sensing device, a second spatial position of said apparatus relative to said point of origin, and to acquire an image of an object in a field of view of said apparatus; and determines a scale factor of said image based on at least said second spatial position, wherein said image scale factor is provided by a ratio of a size of said object along a chosen direction to a size of an image of said object in said chosen direction.
