Zoomed in region of interest

A device, comprising:

• a display;
• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the device to:
• receive a preview stream of a scene from a camera;
• present the preview stream on the display;
• enlarge a first region of interest (ROI) of the scene presented on the display by digitally cropping one or more first frames of the preview stream;
• receive directional input from a user indicating a second ROI of the scene, wherein at least a portion of the second ROI is not currently presented on the display with the enlarged first ROI;
• transition from the enlarged first ROI to an enlarged portion of the second ROI based on the received directional input without adjusting a zoom level of the camera by digitally cropping one or more second frames of the preview stream, wherein the one or more second frames of the preview stream are different than the one or more first frames of the preview stream;
• determine camera settings based on one or more buffered frames of the preview stream, wherein the camera settings include one or more of an auto white balance (AWB) setting, an auto-focus (AF) setting, and an auto-exposure (AE) setting;
• and
• present the enlarged portion of the second ROI on the display based, at least in part, on the camera settings determined based on the one or more buffered frames of the preview stream, wherein the camera settings determined based on the one or more buffered frames are applied to the enlarged portion of the second ROI.

A non-transitory computer-readable medium storing one or more programs containing instructions that, when executed by one or more processors of an apparatus, cause the apparatus to perform operations comprising:

• receiving a preview stream of a scene from a camera;
• presenting the preview stream on a display of the apparatus;
• enlarging a first region of interest (ROI) of the scene presented on the display by digitally cropping one or more first frames of the preview stream;
• receiving directional input from a user indicating a second ROI of the scene, wherein at least a portion of the second ROI is not currently presented on the display with the enlarged first ROI;
• transitioning from the enlarged first ROI to an enlarged portion of the second ROI based on the received directional input without adjusting a zoom level of the camera by digitally cropping one or more second frames of the preview stream, wherein the one or more second frames of the preview stream are different than the one or more first frames of the preview stream;
• determining camera settings based on one or more buffered frames of the preview stream, wherein the camera settings include one or more of an auto white balance (AWB) setting, an auto-focus (AF) setting, and an auto-exposure (AE) setting;
• and
• presenting the enlarged portion of the second ROI on the display based, at least in part, on the camera settings determined based on the one or more buffered frames of the preview stream, wherein the camera settings determined based on the one or more buffered frames are applied to the enlarged portion of the second ROI.

An apparatus, comprising:

• means for receiving a preview stream of a scene from a camera;
• means for presenting the preview stream on a display of the apparatus;
• means for enlarging a first region of interest (ROI) of the scene presented on the display by digitally cropping one or more first frames of the preview stream;
• means for receiving directional input from a user indicating a second ROI of the scene, wherein at least a portion of the second ROI is not currently presented on the display with the enlarged first ROI;
• means for transitioning from the enlarged first ROI to an enlarged portion of the second ROI based on the received directional input without adjusting a zoom level of the camera by digitally cropping one or more second frames of the preview stream, wherein the one or more second frames of the preview stream are different than the one or more first frames of the preview stream;
• means for determining camera settings based on one or more buffered frames of the preview stream, wherein the camera settings include one or more of an auto white balance (AWB) setting, an auto-focus (AF) setting, and an auto-exposure (AE) setting;
• and
• means for presenting the enlarged portion of the second ROI on the display based, at least in part, on the camera settings determined based on the one or more buffered frames of the preview stream, wherein the camera settings determined based on the one or more buffered frames are applied to the enlarged portion of the second ROI.
