Abstract: In an embodiment, an electronic device may be configured to capture still frames during video capture but may capture the still frames in the 4×3 aspect ratio and at higher resolution than the 16×9 aspect ratio video frames. The device may interleave high resolution, 4×3 frames and lower resolution 16×9 frames in the video sequence, and may capture the nearest higher resolution, 4×3 frame when the user indicates the capture of a still frame. Alternatively, the device may display 16×9 frames in the video sequence, and then expand to 4×3 frames when a shutter button is pressed. The device may capture the still frame and return to the 16×9 video frames responsive to a release of the shutter button.

Abstract: A method for automatic image capture control and digital imaging is described. An image buffer is initialized to store a digital image produced by an image sensor, through allocation of a region in memory for the buffer that is large enough to store a full resolution frame from the image sensor. While non-binning streaming frames, from the sensor and in the buffer, are being displayed in preview, the sensor is reconfigured into binning mode, and then binned streaming frames are processed in the buffer, but without allocating a smaller region in memory for the buffer. Other embodiments are also described and claimed.

Abstract: A controller for an image sensor includes a mode selector that receives a selection between image capture mode and data capture mode. An exposure sensor collects exposure data for a scene falling on the image sensor. A command interface sends commands to the image sensor to cause the image sensor to capture an image with a rolling reset shutter operation in which an integration interval for the image sensor is set based on the exposure data if the image capture mode is selected. The integration interval for the image sensor is set to less than two row periods, preferably close to one row period, without regard to the exposure data if the data capture mode is selected. An analog gain may be increased to as large a value as possible in data capture mode. All pixels in a row may be summed before AD conversion in data capture mode.

Abstract: An imaging sensor is signaled to capture a digital image of a dark scene. For each of the pixel columns in the image, a respective column value is computed that represents at least some of the pixels in the column. For each of the pixel columns in the image, a respective comparison is made between the respective column value of the pixel column and a reference value. A respective column score is computed, for each of the pixel columns, based on the respective comparison. An indication that identifies one or more of the pixel columns as anomalous is stored, when the respective column score of the one or more the pixel columns does not meet a criterion. Other embodiments are also described and claimed.

Abstract: Special blend operations for wide area-of-view image generation utilizing a “floating auto exposure” scheme are described. Pixel values in the two images being stitched together are blended within a transition band around a “seam.” identified in the overlap region between the images after changes in exposure and/or color saturation are accounted for. In some embodiments, changes in exposure and/or color saturation are accounted for through the use of one or more exposure mapping curves, the selection and use of which are based, at least in part, on a determined “Exposure Ratio” value, i.e., the amount that the camera's exposure settings have deviated from their initial capture settings. In other embodiments, the Exposure Ratio value is also used to determine regions along the seam where either: alpha blending, Poisson blending—or a combination of the two—should be used to blend in the transitional areas on each side of the seam.
