Abstract
An image converter system comprises an image sensor producing an electrical signal corresponding to the sensed light intensity; a change-in-position sensor physically coupled to the image sensor so as to be moved therewith and to produce output signals corresponding to the changes in position of the image sensor; and a control cirucit for shifting the electrical signals produced by the image sensor according to the changes in position of the image sensor as sensed by the change-in-position sensor, to compensate for the changes in position and thereby to position-stabilize the electrical output of the image sensor.
Claims19
An image converter system comprising:
- an image sensor mountable on a moving body and including an array of light sensing elements each producing an electrical signal corresponding to the light intensity sensed thereby, and means for producing an electrical output corresponding to the light image sensed by said image sensor;
- a change-in-position sensor physically coupled to said image sensor and mountable therewith on the moving body so as to directly sense movements in space of said moving body and thereby of said image sensor, and to produce output signals corresponding to the changes in position in space of said image sensor;
- and control means for shifting the electrical signals produced by said image sensing elements according to the changes in position of said image sensor as sensed by said change-in-position sensor, to compensate for said changes in position and thereby to position-stabilize the electrical output of said image sensor.
An image converter system comprising:
- an area image sensor inc-uding an array of light sensing elements each producing an electrical signal corresponding to the light intensity sensed thereby, and means for producing an electrical output corresponding to the light image sensed by said image sensor;
- a change-in-position sensor physically coupled to said image sensor so as to be moved therewith and to produce output signals corresponding to the changes in position of said image sensor;
- and control means for shifting the electrical signals produced by said image sensing elements according to the changes in position of said image sensor as sensed by said change-in-position sensor, to compensate for said changes in position and thereby to position-stabilize the electrical output of said image sensor;
- said control means comprising:
- a memory plane having a matrix of memory elements arranged in vertical columns and horizontal rows corresponding to the matrix of light sensing elements in said area image sensor;
- an analog-to-digital converter converting the electrical signals from the light sensing elements to digital form;
- memory read-in means shifting the digital electrical signals from the light sensing elements according to the changes-in-position of said area image sensor in both the vertical and horizontal axes as sensed by said change-in-position sensor, and then storing said shifted electrical signals in said memory plane;
- and read-out means for outputting said shifted electrical signals from said memory plane to produce a series of pulses modulated according to the light sensed by said light sensing elements but shifted to compensate for changes-in-position of the area image sensor in both the vertical and horizontal directions.
