Abstract
An imaging method which comprises, while a line of sight of a camera is maintained fixedly oriented towards a target, controlling the camera to acquire an image by a sensor located at a current position relative to the camera, sending a command to an actuator of the sensor, for inducing a motion of the sensor relative to the camera along at least one direction, from the current position to a new position, controlling the camera to acquire an image by each of the pixel bands of the sensor, wherein motion of the sensor is performed during a first period of time, and the sensor is retained stationary at the new position during a second period of time, wherein acquisition of the image is performed during a third period of time, wherein a majority of the third period of time is within the second period of time.
Claims20
An imaging system comprising:
- at least one camera, comprising at least one sensor comprising one or more pixel bands each configured to acquire an image of a fraction of a scene, wherein the sensor is movable, by at least one actuator, relative to the camera along at least one direction,
- a processor and memory circuitry configured to,
- while a line of sight of the camera is maintained fixedly oriented towards a target of a scene:
- (O1) control the camera to acquire an image by each of the pixel bands of the sensor located at a current position relative to the camera,
- (O2) send a command to the actuator to move the sensor relative to the camera along the at least one direction, from the current position to a new position, and
- (O3) control the camera to acquire an image by each of the pixel bands of the sensor,
- wherein motion of the sensor at O2 from the current position to the new position is performed during a period of time PT1, and the sensor is retained stationary at the new position during a period of time PT2,
- wherein acquisition of the image by each of the pixel bands of the sensor at O3 is performed during period of time PT3, wherein at least a majority of the period of time PT3 is within the period of time PT2.
An imaging method comprising:
- providing at least one camera, wherein the camera comprises at least one sensor comprising one or more pixel bands each configured to acquire an image of a fraction of a scene,
- while a line of sight of the camera is maintained fixedly oriented towards a target of a scene:
- (O1) controlling the camera to acquire an image by each of the pixel bands of the sensor located at a current position relative to the camera,
- (O2) sending a command to an actuator of the sensor, for inducing a motion of the sensor relative to the camera along at least one direction, from the current position to a new position,
- (O3) controlling the camera to acquire an image by each of the pixel bands of the sensor,
- wherein motion of the sensor from the current position to the new position is performed during a first period of time PT1, and the sensor is retained stationary at the new position during a second period of time PT2,
- wherein acquisition of the image by each of the pixel bands of the sensor is performed during a third period of time PT3, wherein at least a majority of the third period of time PT3 is within the second period of time PT2.
A non-transitory computer readable medium comprising instructions that, when executed by a processor and memory circuitry, cause the processor and memory circuitry to perform operations comprising:
- while a line of sight of a camera is maintained fixedly oriented towards a target of a scene, wherein the camera comprises at least one sensor comprising one or more pixel bands,
- (O1) controlling the camera to acquire an image by each of the pixel bands of the sensor located at a current position relative to the camera,
- (O2) sending a command to an actuator of the sensor, for inducing a motion of the sensor relative to the camera along at least one direction, from the current position to a new position,
- (O3) controlling the camera to acquire an image by each of the pixel bands of the sensor,
- wherein motion of the sensor from the current position to the new position is performed during a first period of time PT1, and the sensor is retained stationary at the new position during a second period of time PT1,
- wherein acquisition of the image by each of the pixel bands of the sensor is performed during a third period of time PT3, wherein at least a majority of the third period of time PT3 is within the second period of time PT2.
