Definition

(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)

Computational photography requiring combination of optical light modulation and computational reconstruction for acquiring dimensions of the plenoptic function.

Light field imaging systems for light field acquisition:

• using an array of cameras
• using single sensor with temporal, spatial or frequency-domain multiplexing
• Temporal multiplexing with a programmable aperture,
• Spatial multiplexing using an array of lens or prisms,
• Frequency multiplexing by placing heterodyne mask

Camera systems comprising: Different types of image sensors, sensors of different resolutions, sensors with different field of view or focus;

Lensless imaging using:

• coded aperture masks
• Zone plates
• angle-sensitive pixels using diffraction gratings

Coded-aperture imaging;

Extended Depth of Field Photography:

• using focal stacks,
• focal sweep (moving the camera during the exposure),
• coded apertures

High speed imaging using:

• multiple devices,
• high speed illumination,
• stroboscopic illumination,
• synthetic shutter speed imaging.

This group covers image pickup devices using electronic image sensors for computational photography.

Devices for acquisition of colour spectrum, which is one dimension of the plenoptic function are classified in group G01J 3/00.

Pure image processing techniques used regardless of optical light modulation caused by the image pickup device are classified in groups G06T 3/00, G06T 5/00 and H04N 23/80.

High dynamic range imaging and exposure bracketing are classified in groups H04N 23/741 and H04N 23/743, respectively.

High resolution imaging by shifting the sensor relative to the scene is classified in group H04N 25/48.
