The image processing apparatus further includes a short-time exposure distance image generation unit that captures an image with short-time exposure, calculates a parallax from a first short-time exposure image and a second short-time exposure image from a first short-time exposure camera and a second short-time exposure camera disposed at a predetermined interval, and generates a short-time exposure distance image, and a distance image generation unit that combines the long-time exposure distance image with the short-time exposure distance image to generate a distance image.

A remote monitoring device and a remote monitoring method thereof are provided. An energy harvesting device converts energy harvested from the surrounding environment into electrical energy for storage. An image capturing device captures an image of a monitored object to generate a captured image. When the power stored in the energy harvesting device meets a preset condition, a control circuit outputs monitoring information based on the captured image.

A media capture device (MCD) that provides a multi-sensor, free flight camera platform with advanced learning technology to replicate the desires and skills of the purchaser/owner is provided. Advanced algorithms may uniquely enable many functions for autonomous and revolutionary photography. The device may learn about the user, the environment, and/or how to optimize a photographic experience so that compelling events may be captured and composed into efficient and emotional sharing. The device may capture better photos and videos as perceived by one's social circle of friends, and/or may greatly simplify the process of using a camera to the ultimate convenience of full autonomous operation.
