High-level integration needed for compact digital-camera power

摘要

Digital cameras have replaced film cameras as the most popular means of taking pictures. Since the camera body has no need to hold 35mm or APS film, digital cameras are free to be nearly any shape and size that appeals to consumers. Camera functions also become free to incorporate into other products, such as cell phones and PDAs. These new ultra-compact shapes and sizes for cameras provide challenges for design of the battery and power management. These portions of the camera need to be increasingly efficient while using less and less space in each new generation of camera.
