An imaging method and device for a wide dynamic range. |
摘要 |
<p>A method for producing an image with a wide dynamic range using an imaging element in which periods for accumulating charges can be varied in one field is disclosed. The method includes the steps of: reading a charge stored in the imaging element in a first period of the field as a first signal; reading a charge stored in the imaging element in a second period of the field as a second signal, the second period being different from the first period; applying a first weight to the first signal in accordance with the level of the first signal; applying a second weight to the second signal in accordance with the level of the second signal; producing a synthesized signal by synthesizing the weighted first signal and the weighted second signal; and compressing the level of the synthesized signal to a predetermined standard level. <IMAGE></p> |
