Automatic white balance adjusting device |
摘要 |
<p>An automatic white balance adjusting device adjusts the white balance of a white object which is indoors under the influence of bright sunlight, or a white object which is indoors under the influence of dull sunlight light and a fluorescent lamp. The device includes a weighting circuit for a fluorescent lamp block, and a weighting circuit for a sunlight-and-tungsten-lamp block. The former weights an average of the fluorescent lamp block, while the latter weights an average of the sunlight-and-tungsten-lamp block. The weighted averages are used to generate a white balancing signal, which will be used for white balancing a white object. <IMAGE></p> |
