Visual-inertial tracking of an eyewear device using a rolling shutter camera(s). The eyewear device includes a position determining system. Visual-inertial tracking is implemented by sensing motion of the eyewear device. An initial pose is obtained for a rolling shutter camera and an image of an environment is captured. The image includes feature points captured at a particular capture time. A number of poses for the rolling shutter camera is computed based on the initial pose and sensed movement of the device. The number of computed poses is responsive to the sensed movement of the mobile device. A computed pose is selected for each feature point in the image by matching the particular capture time for the feature point to the particular computed time for the computed pose. The position of the mobile device is determined within the environment using the feature points and the selected computed poses for the feature points.

A solid state image sensor includes a pixel array, as well as charge-to-voltage converters, reset gates, and amplifiers each shared by a plurality of pixels in the array. The voltage level of the reset gate power supply is set higher than the voltage level of the amplifier power supply.

The image sensor may also include a row scanner configured such that, while scanning a row in the pixel array to read out signals therefrom, the row scanner resets the charge in the photodetectors of the pixels sharing a charge-to-voltage converter with pixels on the readout row. The charge reset is conducted simultaneously with or prior to reading out the signals from the pixels on the readout row.

Image frames for computational photography may be corrected, such as through rolling shutter correction (RSC), prior to fusion of the image frames to reduce wobble and jitter artifacts present in a video sequence of HDR-enhanced image frames. First and second motion data regarding motion of the image capture device may be determined for times corresponding to the capturing of the first and second image frames, respectively. The rolling shutter correction (RSC) may be applied to the first and second image frames based on both the first and second motion data. The corrected first and second image frames may then be aligned and fused to obtain a single output image frame with higher dynamic range than either of the first or second image frames.
