A new patent application filed by Apple revealed that the Cupertino-based firm is designing an advanced camera flash system and the company is exploring the possibilities of flash re-directors and improved imaging sensors in its upcoming digital cameras. Technology blog Patently Apple has dissected the filing, which is related to flash re-directors and new imaging sensors.

The Apple filing states that the company could integrate the system in to a wide variety of Apple products including its desktop and laptop computers. The company is also planning to use the system in devices based on its iOS operating system and in Apple camera as well.

Patently Apple revealed that the flash re-directors would work by selectively illuminating certain areas of a scene. It will not provide blanket lighting for the whole picture. The patent allows for a lens that redirects a fixed light source, or multiple flashes, which means that it is a movable light source. The light source can either be automatically aimed at the place where it is needed or the photographer can control it.

It is to be noted Apple improved the photographic capabilities of its hugely successful smartphone- the iPhone range by releasing the iOS 4.1 software update. The update added high dynamic range, which takes several versions of the same picture, automatically and also tweaks the exposure for each one automatically. The technology will then combine the pictures in to a single image with near-perfect color tone and balance. Meanwhile, Apple has refunded money to some customers who paid for new Apple TV, citing a “delay”.
