Solving the challenges of traditional optics

Today’s optics are typically composed of many lenses. Each lens element corrects specific geometric and chromatic aberrations that arise during image capture. Adding lenses further corrects the image, but with a trade-off: Additional weight, thickness and cost for a device.

Traditional optics have therefore hit a wall: Their size can no longer be reduced significantly for cameras inside thin devices (smartphones, tablets, etc.).

Lenses in smart devices are small and plastic, and cannot match the quality of those in a full-sized camera, especially for low-light images. As sensors and pixels get smaller, the probability of blur and other aberrations in pictures increases.

Algolux Virtual Lens

Algolux Virtual Lens corrects optical aberrations. This enables sharper, more detailed photos. Additionally, Virtual Lens empowers flexibility in lens design that can be used to reduce the cost and/or the number of lenses. This approach can also be used to improve camera production yield.

Algolux Virtual IS

Algolux Virtual IS provides image stabilization by correcting motion blur and shutter shake, two common problems that arise when taking pictures in low-light conditions. Virtual IS uses a secondary camera (for example, the front-facing camera on a smartphone) to track the micro-movements causing the blur. It then uses this information to deblur the image. The resulting low-light pictures are sharp and blur-free.
