Method and apparatus for electronically aligning active elements of an imaging array with an optical system. |
摘要 |
<p>An imaging apparatus includes an array (20) of light responsive elements (28) outputs from which are utilized in generating data representative of an object such as a cheque (12). The apparatus includes an optical system having a lens (32) for directing light from the cheque (12) on to a predetermined number of the linght responsive elements (28), which number is less than the total number of elements in the array (20). Switch means are provided for adjustably selecting a particular group of elements (28) substantially corresponding to the elements upon which light from the cheque (12) impinges.</p><p>The method of selecting said particular group of elements involves selecting successive groups of contiguous elements (28) until the outputs of the first and last elements of such a group are found to be substantially equal.</p> |
