Title:
IMAGING DEVICE, IMAGING DEVICE IMAGE OUTPUT METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2004/030348
Kind Code:
A1
Abstract:
There is provided an imaging device capable of dynamically allocating an output image in a dynamic range according to an object. The imaging device includes: an imaging element (131) for imaging an object; a signal processing section (133) for combining a long-time exposure image having a relatively long exposure time imaged by the imaging element and a short-time exposure image having a relatively short exposure time imaged by the imaging element, thereby creating a combined image having a relatively wider dynamic range than the dynamic range of the long-time exposure image or the short-time exposure image; and a control section (137) for compressing the combined image and dynamically modifying the distribution ratio of the high-luminance dynamic range and the low-luminance and intermediate-luminance dynamic range among the dynamic ranges of the output image output as a video signal.
