HDR Camera

Description: Capture high quality HDR images in full resolution

Capture high quality High Dynamic Range images:

– Full resolution
– Take HDR image in one tap
– HDR image fused and tone-mapped on device within seconds
– Don’t have to be rock-solid while shooting
– Correct handling of moving objects and de-ghosting
– You can control tone-mapping parameters: contrast, micro-contrast, color vividness, exposure
– Save original exposure bracketed images

Real life scenes often have a wide range of light intensity, which cannot be captured by a camera. In a photo of such a scene the bright areas look washed out and everything in shadows is pictured as a black spot with no details. The HDR technique allows you to capture details in bright and dark areas and have them merged in a single photo.

HDR photography is widely adopted by professional photographers. Wouldn’t it be nice to have an HDR in mobile phones?

The problem is that HDR requires taking several differently exposed images in series, which must be precisely aligned and then fused. In order to be usable for real life scenes, the HDR feature should include moving object detection and hand shake compensation to avoid or minimize the ghosting in the final image. That requires a lot of computational resources and makes a challenge even for professional desktop HDR software.

Almalence has brought its expertise in professional HDR software to mobile phones. Our HDR fusion algorithms compensate hand shaking and detect moving objects in the scene, suppressing ghosting artifacts. At the same time, the algorithms are quick enough to provide comfortable processing time on mobile devices.

The camera technology talk in the description went totally over my head.  I still have no idea how HDR technology affects the picture. Here are 2 pictures I took.  One is with the HDR Camera App and the other is with my default camera app.  Both these pictures we’re taken with an HTC Sensation 4g, 8MP. The photo with the HDR app looked a little more grainy but the colors looked better.  I’m not sure if I have the settings correct. I used the default settings.

Here’s some additional information on HDR technology.



I’d welcome comments from photophiles with experience using the HDR camera app.
