Samsung Patent Creates Shallow Depth of Field in Compact Cameras
Compact cameras are handy, mobile, and they provide a simple point-and-shoot option without fuss. However, creating shallow depth of field has always plagued this genre of cameras since its inception, including those embedded in mobile phones. Samsung's latest patent takes care of this by blurring the background based on depth information captured from the imaginary camera's twin lenses.
Photography Bay - In a recently published patent application, Samsung disclosed an invention that puts shallow depth-of-field capabilities into tiny, point and shoot cameras. Samsung gets there by using dual lenses in a single camera and using that second lens in a rather novel way.
The primary lens captures the entire image in Full-HD, while the secondary lens and sensor evaluate distance of different areas in the image. Essentially, this data is compared to data captured from the primary lens to produce a depth map. A graduated blur of the background is created based on this depth disparity. More on this story here.
