Pixel unit for an image sensor, image sensor, method for sensing a light signal, method of controlling a pixel unit, and method for generating an image using a pixel unit

A method for sensing a light signal, the method comprising:

• converting the light signal into a processing signal;
• generating at least a first multiplexer signal and a second multiplexer signal that deviates therefrom using the processing signal;
• and
• buffer storing a time-limited integral value of the first multiplexer signal in a first storage unit and a time-limited integral value of the second multiplexer signal in a second storage unit.

A method for generating an image using a pixel unit, the pixel unit including a photodiode for converting a light signal into a processing signal, a multiplexer unit designed to use the processing signal to generate at least a first multiplexer signal and a second multiplexer signal that deviates therefrom, and

• a storage device having at least a first storage unit for buffer storing the first multiplexer signal and a second storage unit for buffer storing a time-limited integral value of the second multiplexer signal, the method comprising:
• inputting the first multiplexer signal and the second multiplexer signal via an interface to the storage device;
• and
• reconstructing an image signal representing the image using the first multiplexer signal and the second multiplexer signal.

A device comprising units configured to sense a light signal, the device configured to:

• convert the light signal into a processing signal;
• generate at least a first multiplexer signal and a second multiplexer signal that deviates therefrom using the processing signal;
• and
• buffer store a time-limited integral value of the first multiplexer signal in a first storage unit and a time-limited integral value of the second multiplexer signal in a second storage unit.
