SOLID STATE IMAGING ELEMENT AND IMAGING DEVICE |
摘要 |
<p>A pixel output line (14) is independently provided for each of the pixels arranged in a two-dimensionally array within a pixel area so that pixel signals can be sequentially written in a plurality of memory sections (22) through the pixel output lines (14). When a plurality of frames of pixel signals are held in the memory sections (22), the pixel signals corresponding to two arbitrarily selected frames are read and respectively stored in sample-and-hold circuits (61 and 62), and their difference is obtained. Then, the difference signals corresponding to a predetermined range of the image are integrated, and the integrated value is compared with a threshold. If the integrated value exceeds the threshold, it is presumed that a change in an imaging object has occurred, and a pulse generation circuit (66) generates a trigger signal. By controlling the discontinuation and other imaging actions according to this trigger signal, it is possible to correctly take high-speed images of the situation before or after the occurrence of an objective phenomenon.</p> |
