| 摘要 |
The invention relates to an image sensor for electronic cameras, having a plurality of light-sensitive pixels for the generation of at least one signal proportional to exposure, wherein the pixels are coupled to a read-out circuit having at least one amplifier and configured to amplify the at least one signal of a respective pixel with different amplification factors to generate differently amplified signals for the at least one signal of a respective pixel, wherein the read-out circuit has at least one output to output at least some of the differently amplified signals as output signals. At least three different amplification factors can be selected for the at least one signal of a respective pixel, wherein the read-out circuit includes a selection device which is configured to select those amplification factors in dependence on the level of the at least one signal of a respective pixel with which the output signals of the read-out circuit are amplified, wherein the number of output signals for the at least one signal of a respective pixel amounts to at least two and is less than the number of the selectable amplification factors. |
