发明名称 Apparatus and associated methodology of widening dynamic range in image processing
摘要 An image processing apparatus includes an imaging device converting light incident thereon into charge, a determining unit determining for each pixel of the device whether an accumulated charge of the pixel reaches a threshold charge within a shutter period, a measuring unit measuring a threshold arrival period elapsed until the charge reaches the threshold charge, a memory unit storing at least the threshold arrival period of a pixel for which the determining unit determines that a charge of the pixel reaches the threshold charge, an arithmetic unit calculating a charge to be accumulated by incident light in the shutter period on the basis of the stored threshold arrival period and the threshold charge, and a generating unit generating an imaging signal using a pixel value corresponding to the calculated charge as a pixel value of the pixel for which the determining unit determines that the charge reaches the threshold charge.
