Abstract
A method for image capture control may include computing an electronic image stabilization (EIS) compensation based on image data from an image capture device, the image data having a first region of interest (ROI). A jitter or panning shift is computed based on the EIS compensation. The first ROI is adjusted for use in at least one of the group consisting of an automatic white balance process and an automatic exposure process of the image capture device based on the jitter or panning shift.
Claims25
A method for image capture control, comprising:
- computing an electronic image stabilization (EIS) compensation based on image data from an image capture device, the image data having a first region of interest (ROI);
- computing a jitter or panning shift based on the EIS compensation, wherein computing the jitter or panning shift comprises sensing a motion of the image capture device, and dividing the motion of the image capture device into a panning shift component and a jitter component;
- and
- adjusting the first ROI for use in at least one of the group consisting of an automatic white balance process and an automatic exposure process of the image capture device based on the jitter or panning shift, wherein adjusting the first ROI compensates for the jitter component without compensating for the panning shift component.

Image capture control apparatus, comprising:
- an electronic image stabilizer for outputting a first signal based on image data from an image capture device, the image data having a first region of interest (ROI);
- a jitter estimator configured to compute a jitter or panning shift based on the first signal;
- an ROI adjuster configured to compute an adjusted ROI based on the jitter or panning shift, for use in at least one of the group consisting of a white balance process and an automatic exposure process of the image capture device,
- wherein the image capture device includes an imaging sensor comprising a plurality of buffer pixel rows and buffer pixel columns at a periphery of the imaging sensor, and the ROI adjuster is configured to select the adjusted ROI to include at least one of the buffer pixel rows or at least one of the buffer pixel columns.

A non-transitory, machine-readable storage medium encoded with program code for image capture control, wherein the program code comprises:
- code for computing an electronic image stabilization (EIS) compensation based on image data from an image capture device, the image data having a first region of interest (ROI);
- code for computing a jitter or panning shift based on the EIS compensation, including sensing a motion of the image capture device, and dividing the motion of the image capture device into a panning shift component and a jitter component;
- and
- code for adjusting the first ROI for use in at least one of the group consisting of an automatic white balance process and an automatic exposure process of the image capture device based on the jitter or panning shift, wherein adjusting the first ROI compensates for the jitter component without compensating for the panning shift component.
