Dual lens keeps things in focus

There is a new camera and sensor modules in Taiwanese phone maker HTC's update of its flagship phone, HTC One (M8).

REAR DUO LENS CAMERA

HTC is continuing with its Ultrapixel push and using a larger sensor for the rear-facing camera, instead of jacking up megapixel-lens numbers.

Like the original HTC One, the HTC One (M8) uses a 4MP lens and larger 1/3-inch sensor to capture images.

Both the camera and sensor modules here are new. The rear camera also has a new duo-camera module. A second, smaller lens is sited above the rear lens.

With the dual lens, the phone is capable of depth capture and can take photos with every object in focus - from 50cm in front of the camera to 4m.

When shooting a photo, you can shift the focus to bring the background, foreground, or anywhere in between, into focus.

Upcoming devices, such as the Samsung Galaxy S5, also have this feature, but HTC implements this in a different way.

When a subject is placed in focus, the software subtly blurs out the rest of the image, creating a tilt-shift effect in the final picture.

CAMERA SOFTWARE

Software improvements also make it possible to highlight a subject in the foreground, as well as change the background to black-and-white or make it look like a sketch.

HTC says future software updates may even allow users to merge photos with the same background together.

In this way, subjects from different pictures can be stitched together.

FRONT CAMERA

Recognising the cultural impact of the selfie, HTC has given its new flagship a 5MP front camera, with an f2 aperture.

The difference in image quality is obvious, especially as the camera has a wide-angled lens which takes slimmer-looking body shots - perfect for close-ups.
