Image sensor with selectable amplification factors

An image sensor for electronic cameras, having a plurality of light-sensitive pixels (2) for the generation of at least one signal proportional to exposure, with the pixels (2) being coupled to a read-out circuit (4) which has at least one amplifier (60, 61, 62;

• 160;
• 260, 261) and which is configured to amplify the at least one signal of a respective pixel (2) with different amplification factors to generate differently amplified signals for the at least one signal of a respective pixel (2), with the read-out circuit (4) having at least one output (43, 44;
• 143;
• 243, 244) to output at least some of the differently amplified signals as output signals,
• wherein at least three different amplification factors can be selected for the at least one signal of a respective pixel (2), with the read-out circuit (4) including a selection device (30, 31, 33;
• 130, 131, 133;
• 230, 231, 233) which is configured to select, in dependence on a level of the at least one signal of a respective pixel (2), the amplification factors with which the output signals of the read-out circuit (4) are amplified, wherein the number of output signals for the at least one signal of a respective pixel (2) amounts to at least two and is less than the number of the selectable amplification factors.
