Abstract
In a method for testing an image sensor having (i) regular pixels and test pixels, of which each is interconnected with one of two predefined voltage values, and (ii) a signal processing unit for providing digital signal values for output voltages of the pixels and test pixels, the following steps are performed: receiving digital signal values of the test pixels; and using the signal values of at least one proper or improper subset of the test pixels for testing the image sensor, all test pixels of the subset being interconnected with a first of the two voltage values. Using the test pixels for testing allows testing during ongoing operation, i.e., during reception of regular image signals.
