Modeless video and still frame capture using interleaved frames of video and still resolutions

A method comprising:

• during a video capture from a first plurality of frames from an image sensor, wherein the first plurality of frames have a first resolution, generating an interleaved sequence of first frames at the first resolution and first aspect ratio associated with still frames and second frames captured at a second resolution and second aspect ratio associated with a video, wherein the first aspect ratio is different from the second aspect ratio, and wherein the second resolution is less than the first resolution;
• displaying a second plurality of frames on a display device at the first aspect ratio associated with still frames and a third resolution that is less than the first resolution, wherein the second plurality of frames further include an indication of the second aspect ratio within the second plurality of frames, whereby a location of images within the second plurality of frames at the first aspect ratio and at the second aspect ratio is visible on the display device, and wherein the portion of the second plurality of frames within the indication of the second aspect ratio represent the images captured by the video capture, and wherein one of the first frames at the first aspect ratio is captured in a still frame in response to a request for the still frame;
• detecting the request for the still frame;
• and delivering the one of the first frames at the first resolution and first aspect ratio as the still frame.

An integrated circuit comprising:

• an image signal processor (ISP) coupled to an input to the integrated circuit, wherein the ISP is configured to receive a first plurality of frames have a first resolution from an image sensor through the input, and wherein the ISP is configured to generate a second plurality of frames forming a first video sequence, wherein a first subset of the second plurality of frames have the first resolution and a first aspect ratio that is associated with still frames, and wherein a second subset of the second plurality of frames have a second resolution that is less than the first resolution and a second aspect ratio that is associated with video frames, and wherein the second aspect ratio is different from the first aspect ratio;
• and
• a display controller configured to transmit a third plurality of frames forming a second video sequence derived from the first video sequence to a display device for display, wherein the second video sequence has the first aspect ratio associated with still frames and a third resolution that is less than the first resolution, and wherein the third plurality of frames further include an indication of the second aspect ratio within each frame having the first aspect ratio, whereby a location of images within the third plurality of frames at the first aspect ratio and at the second aspect ratio is visible on aspect ratio is visible on the display device, and wherein the portion of the plurality of frames within the indication of the second aspect ratio represent the images captured as an output video sequence, and wherein one of the plurality of frames at the first aspect ratio is captured in a still frame in response to a request to capture the still frame.
