摘要： Camera compensation methods and systems that compensate for misalignment of sensors/camera in stereoscopic camera systems. The compensation includes identifying a pitch angle offset between a first camera and a second camera, determining misalignment of the first and second cameras from the identified pitch angle offset, determining a relative compensation delay responsive to the determined misalignment, introducing the relative compensation delay to image streams produced by the cameras, and producing a stereoscopic image on a display from the first and second image streams with the introduced delay.

摘要： An auto exposure method for an image capture device includes the steps of gathering ambient light data using an ambient light sensor of the image capture device, selecting a frame rate corresponding to the gathered ambient light data, and determining an optimal image capture frame rate for the image capture device. The auto exposure method determines the optimal image capture frame rate by executing an auto exposure algorithm with a processor using the selected frame rate as an initialization parameter for the auto exposure algorithm.

摘要： Eyewear devices that include two SoCs that share processing workload. Instead of using a single SoC located either on the left or right side of the eyewear devices, the two SoCs have different assigned responsibilities to operate different devices and perform different processes to balance workload. In one example, the eyewear device utilizes a first SoC to operate a first color camera, a second color camera, a first display, and a second display. The first SoC and a second SoC are configured to selectively operate a first and second computer vision (CV) camera algorithms. The first SoC is configured to perform visual odometry (VIO), track hand gestures of the user, and provide depth from stereo images. This configuration provides organized logistics to efficiently operate various features, and balanced power consumption.

In one example, the eyewear device utilizes a first SoC to operate the OS, a first color camera, a second color camera, a first display, and a second display. A second SoC is configured to run computer vision (CV) algorithms, visual odometry (VIO), tracking hand gestures of the user, and providing depth from stereo.

摘要： A system, method, and computer program product for providing pseudo 3D user interface effects in a digital camera with existing lens distortion correction hardware. A distortion map normally used to correct captured images instead alters a displayed user interface object image to support production of a “pseudo 3D” version of the object image via production of at least one modified image. A blending map also selectively mixes the modified image with a second image to produce a distorted blended image. A set or series of such images may be produced automatically or at user direction to generate static or animated effects in-camera without a graphics accelerator, resulting in hardware cost savings and extended battery life.
摘要翻译： 一种用于在具有现有透镜失真校正硬件的数码相机中提供伪3D用户界面效果的系统，方法和计算机程序产品。 通常用于校正捕获的图像的失真图，而不是改变显示的用户界面对象图像，以支持通过生成至少一个修改的图像来生成对象图像的“伪3D”版本。 混合图还选择性地将修改的图像与第二图像混合以产生失真的混合图像。 可以自动地或在用户方向产生一组或一系列这样的图像，以在没有图形加速器的情况下在相机中产生静态或动画效果，从而节省硬件成本并延长电池寿命。

摘要： An electronic eyewear device includes first and second systems-on-chip (SoCs) having independent time bases. The first and second SoCs are connected by a shared general purpose input/output (GPIO) connection and an inter-SoC interface. The first and second SoCs are synchronized to each other by the first SoC asserting the shared GPIO connection to the second SoC where assertion of the message to the shared GPIO connection triggers an interrupt request (IRQ) at the second SoC. The first SoC records a first timestamp for assertion of the message to the GPIO connection, and the second SoC records a second timestamp of receipt of the IRQ. The first SoC sends a message including the first timestamp to the second SoC over the inter-SoC interface. The second SoC calculates a clock offset between the first and second SoCs as a difference between the first and second timestamps.
