Abstract

A primary exposure and an effects exposure of a scene are captured via a digital imaging sensor. During at least the effects exposure, the scene is caused to shift in a predetermined pattern relative to the digital imaging sensor via an image stabilizing device. The effects exposure and the primary exposure are combined to form a digital image.

First claim

What is claimed is:

1. A method, comprising:
causing a primary exposure and an effects exposure of a scene to be captured via a digital imaging sensor, wherein the effects exposure comprises detecting only a portion of the scene via the sensor;
during at least the effects exposure, causing the scene to shift in a predetermined pattern relative to the digital imaging sensor via an image stabilizing device; and
combining the effects exposure and the primary exposure to form a digital image showing an artifact resulting from the predetermined pattern.

2. The method of claim 1 , wherein the effects exposure is configured so that only a relatively bright portion of the scene is detected via the digital imaging sensor, and the predetermined pattern is a geometric shape, such that the artifact comprises a relatively bright portion of the scene tracing a pattern in the form of the geometric shape over the primary exposure in the digital image.

3. The method of claim 1 , wherein the artifact comprises a portion of the digital image being out of focus.

4. The method of claim 1 , further comprising causing a flash to illuminate the primary exposure but not the effects exposure.

5. The method of claim 1 , wherein the image stabilizing device moves a lens to cause the scene to shift relative to the digital imaging sensor.

6. The method of claim 1 , wherein the image stabilizing device moves the digital imaging sensor to cause the scene to shift relative to the digital imaging sensor.

7. A non-transitory computer readable medium storing instructions that are executable by a processor to perform the method of claim 1 .

8. An apparatus, comprising:
at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
causing a primary exposure and an effects exposure of a scene to be captured via a digital imaging sensor of the apparatus, wherein the effects exposure comprises detecting only a portion of the scene via the sensor;
during at least the effects exposure, causing the scene to shift in a predetermined pattern relative to the digital imaging sensor; and
combining the effects exposure and the primary exposure to form a digital image showing an artifact resulting from the predetermined pattern.

9. The apparatus of claim 8 , wherein the scene is caused to shift relative to the digital imaging sensor via an image stabilizing device of the apparatus.

10. The apparatus of claim 9 , wherein the image stabilizing device moves a lens to cause the scene to shift relative to the digital imaging sensor.

11. The apparatus of claim 9 , wherein the image stabilizing device moves the digital imaging sensor to cause the scene to shift relative to the digital imaging sensor.

12. The apparatus of claim 8 , wherein the effects exposure is configured so that only a relatively bright portion of the scene is detected via the digital imaging sensor, and the predetermined pattern is a geometric shape, such that the artifact comprises a relatively bright portion of the scene tracing a pattern in the form of the geometric shape over the primary exposure in the digital image.

13. The apparatus of claim 8 , wherein the artifact comprises a portion of the digital image being out of focus.

14. The apparatus of claim 8 , wherein the apparatus causes a flash to illuminate during the primary exposure but not the effects exposure.

15. An apparatus comprising:
a digital imaging sensor;
an image stabilizing device; and
at least one processor and at least one memory including computer program code, the at least one processor coupled to the digital imaging sensor and the image stabilizing device, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
causing a primary exposure and an effects exposure of a scene to be captured via the digital imaging sensor, wherein the effects exposure comprises detecting only a portion of the scene via the sensor; and
during at least the effects exposure, actuating the image stabilizing device to cause the scene to shift in a predetermined pattern relative to the digital imaging sensor; and
combining the effects exposure and the primary exposure to form a composite digital image showing an artifact resulting from the predetermined pattern.

16. The apparatus of claim 15 , wherein the image stabilizing device moves the digital imaging sensor to cause the scene to shift relative to the digital imaging sensor.

17. The apparatus of claim 15 , wherein the effects exposure is configured so that only a relatively bright portion of the scene is detected via the digital imaging sensor, and the predetermined pattern is a geometric shape, such that the artifact comprises a relatively bright portion of the scene tracing a pattern in the form of the geometric shape over the primary exposure in the digital image.

18. The apparatus of claim 15 , wherein the artifact comprises a portion of the digital image being out of focus.

19. The apparatus of claim 15 , wherein a flash is energized to illuminate the primary exposure but not the effects exposure.

20. The apparatus of claim 15 , wherein the apparatus comprises a mobile device.
