Cheap Complex Cameras - Challenges and Solutions in Embedded Linux

Explore the intricacies of cheap complex cameras in mobile devices through this informative conference talk. Delve into the unique challenges of phone cameras compared to webcams, including resolution switching, high-bit depth sensors, and the need for complex software support. Learn about the limitations of current applications for still photography with mainline kernels and the inadequacies of libv4l2 for digital photography. Discover the importance of auto-exposure, auto-gain, and auto-focus features in producing quality images. Gain insights into kernel hacking, USB stack development, and hibernation from Pavel Machek's extensive experience. Examine topics such as the Media-control API, kernel progress, FCam-dev, and future goals in camera technology. Investigate performance research on 1MPix data, the sdicam project, and the challenges of auto-gain and auto-focus implementation. Discuss the asynchronous nature of V4L2 and explore wishlists for v4l-utils and broader camera application development. Understand the significance of white balance and lens shading in producing high-quality images.
