Abstract

An apparatus and a method for capturing image frames using interlaced exposure. The apparatus includes a digital camera and a memory. The digital camera includes an image sensor and the memory includes camera settings. The apparatus further includes a processor and a user interface. The user interface enables a user to manually input or adjust image capture parameter values including at least one first capture parameter value for a first set of pixels from the image sensor, and, at least one second capture parameter value for a second set of pixels from the image sensor. The processor controls the digital camera to expose the first set of pixels using the at least one first capture parameter value and the second set of pixels using the at least one second capture parameter value, where exposures of the first set of pixels and the second set of pixels overlap in time.

First claim

The invention claimed is:

1. An apparatus comprising:
a digital camera;
at least one memory comprising camera settings;
a processor communicably coupled with the digital camera and the at least one memory and configured to control operation of the digital camera together with the camera settings stored in the at least one memory; and
a user interface for at least one of inputting and adjusting the camera settings, wherein the user interface enables a user to at least one of manually inputting and adjusting image capture parameter values comprising:
a plurality of first capture parameter values for a first set of pixels of an interlaced image capture; and
a plurality of second capture parameter values for a second set of pixels of the interlaced image capture,

wherein the processor is configured to store at least one first capture parameter value and at least one second capture parameter value in the at least one memory, and to control the digital camera to capture at least one digital image frame using the interlaced image capture by using the at least one first capture parameter value for the first set of pixels and using the at least one second capture parameter value for the second set of pixels,
wherein the camera settings comprise adjustable settings for two or more of the following capture parameters: exposure compensation, shutter speed, white balance, ISO, delay, zoom, aperture, flash, and flash color temperature, the adjustable settings configured to enable at least one of the inputting and the adjusting of capture parameter values corresponding to a selection of at least one capture parameter from the two or more capture parameters.

2. The apparatus of claim 1 , wherein the processor is configured to cause the digital camera to capture:
a first partial image frame by using the at least one first capture parameter value for the first set of pixels during the interlaced image capture; and
a second partial image frame by using the at least one second capture parameter value for the second set of pixels during the interlaced image capture.

3. The apparatus of claim 2 , wherein the processor is configured to combine the first partial image frame and the second partial image frame to generate a digital image frame.

4. The apparatus of claim 3 , wherein the first partial image frame comprises odd pairs of lines of the digital image frame and the second partial image frame comprises even pairs of lines of the digital image frame.

5. The apparatus of claim 3 , wherein the first partial image frame comprises odd lines of the digital image frame and the second partial image frame comprises even lines of the digital image frame.

6. The apparatus of claim 1 , wherein the processor is configured to cause the digital camera to capture a plurality of digital image frames in a sequence to facilitate generation of a video from the plurality of digital image frames, each digital image frame from among the plurality of digital image frames generated by combining corresponding first and second partial image frames, the first and the second partial image frames captured by exposing the first set of pixels and the second set of pixels using the at least one first capture parameter value and the second capture parameter value, respectively.

7. The apparatus of claim 1 , wherein the camera settings comprise adjustable settings for three or more of the following capture parameters:
exposure compensation, shutter speed, white balance, ISO, delay, zoom, aperture, flash and flash color temperature.

8. The apparatus of claim 7 , wherein the processor is configured to cause the user interface to present an interactive display to the user, the interactive display displaying the adjustable settings corresponding to the at least one capture parameter to enable the user to provide input related to the at least one first capture parameter value and the at least one second capture parameter value.

9. The apparatus of claim 8 , wherein the interactive display is configured to enable the user to individually adjust the first and the second capture parameter values to at least one of same values and different values.

10. The apparatus of claim 9 , wherein the first and the second capture parameter values are displayed to the user on the interactive display at a same time.

11. An apparatus comprising:
a digital camera;
at least one memory comprising camera settings, wherein the camera settings comprise adjustable settings for two or more of the following capture parameters: exposure compensation, shutter speed, white balance, ISO, delay, zoom, aperture, flash, and flash color temperature;
a processor communicably coupled with the digital camera and the at least one memory and configured to control operation of the digital camera together with the camera settings stored in the at least one memory; and
a user interface for at least one of inputting and adjusting the camera settings, wherein the user interface enables a user to at least one of manually inputting and adjusting image capture parameter values comprising:
a plurality of first capture parameter values for a first set of pixels of an interlaced image capture; and
a plurality of second capture parameter values for a second set of pixels of the interlaced image capture,

wherein the processor is configured to store at least one first capture parameter value and at least one second capture parameter value in the at least one memory, and to control the digital camera to capture at least one digital image frame using the interlaced image capture by using the at least one first capture parameter value for the first set of pixels and using the at least one second capture parameter value for the second set of pixels.

12. The apparatus of claim 11 , wherein each digital image frame from among the at least one digital image frame is generated by combining:
a first partial image frame captured by using the at least one first capture parameter value for the first set of pixels during the interlaced image capture; and
a second partial image frame captured by using the at least one second capture parameter value for the second set of pixels during the interlaced image capture.

13. The apparatus of claim 12 , wherein the first partial image frame comprises odd pairs of lines of the digital image frame and the second partial image frame comprises even pairs of lines of the digital image frame.

14. The apparatus of claim 12 , wherein the first partial image frame comprises odd lines of the digital image frame and the second partial image frame comprises even lines of the digital image frame.

15. The apparatus of claim 11 , wherein the processor is configured to cause the user interface to present an interactive display to the user, the interactive display displaying adjustable settings corresponding to at least one capture parameter to enable the user to provide input related to the at least one first capture parameter value and the at least one second capture parameter value.

16. The apparatus of claim 15 , wherein the interactive display is configured to enable the user to individually adjust the first and the second capture parameter values to at least one of same values and different values.
