Imaging device with extended dynamic range |
摘要 |
An imaging device comprises: an imaging element (1) capable of reading accumulated charges of different exposure times in a predetermined frame period, the imaging element being divided into groups for long-time exposure and short-time exposure; and a timing pulse generator (2) for adjusting read timings of the imaging element (1). A first read timing at which an accumulated charge of long-time exposure is read from the group for long-time exposure and a second read timing at which an accumulated charge of short-time exposure is read from the group for short-time exposure are adjusted separately from each other. This provides an imaging device that can extend the dynamic range according to the degree of contrast between light and shade of a subject. |
