Exposure time estimation for high dynamic range imaging with hand held camera
Original language description
The limited dynamic range of a camera may be extended by composing differently exposed images of the same scene. The nonlinear camera has to be calibrated radiometrically first. We show that the calibration process can be difficult for real cameras. Theimprovement can be achieved if linear 12-bit RAW images are used as offered by modern mid-class and professional cameras. The knowledge of exposure time positively affects the radiometric quality of the composed high dynamic range (HDR) image. This knowledge also helps in registration of differently exposed hand held shots. This contribution presents a new method for estimating exposure times from the histograms of images captured using a linear response camera or generated from a RAW image. The presented method does not require spatially aligned images. The actual process of HDR image composition needs perfectly aligned images on its input. We present a method for registering differently exposed images captured with a hand held camera.
