Portable encoded information reading terminal configured to acquire images
First Claim
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.

Abstract
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.

11. A method of producing an image of an object by an apparatus comprising a motion sensing device, said method comprising:
-
responsive to detecting a pre-defined pattern in a first plurality of values received from said motion sensing device, said apparatus storing in memory a first spatial position of said apparatus as a point of origin; responsive to detecting a user interface command, determining, based on a second plurality of values received from said motion sensing device, a second position of said apparatus relative to said point of origin; acquiring an image of said object; and determining a scale factor of said image based on at least said second spatial position, wherein said image scale factor is provided by a ration of a size of said object along a chosen direction to a size of an image of said object in said chosen direction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
