TECHNIQUES FOR CORRECTING VIDEO ROLLING SHUTTER JELLO EFFECT FOR OPEN LOOP VOICE-COIL MOTOR CAMERAS

Abstract:

Methods, systems, and devices for techniques for correcting video rolling shutter jello effect for open loop voice-coil motor cameras are described. A device may capture an image using an open loop voice-coil motor camera including a lens barrel assembly, a base mount, and a brake caliper. The base mount associated with the lens barrel assembly may include the brake caliper. The device may determine a vibration frequency parameter associated with a gyroscope sensor exceeds a threshold. Based on the vibration frequency parameter exceeding the threshold, the device may measure an image sharpness parameter associated with the image. In some aspects, the device may configure engagement of the brake caliper with the lens barrel assembly based on the image sharpness parameter.
