Abstract
An image capture device includes an image sensor. The image sensor includes a temperature sensor for measuring temperature measurements of the image sensor. A timing generator is coupled to the image sensor for applying an electronic shutter pulse to the image sensor to drain away all charge in photodiodes of the image sensing region prior to image capture. A reading component is coupled to the temperature sensor for reading the temperature measurements from the temperature sensor. The image capture device is configured to prevent erroneous temperature readings by the reading component resulting from substrate punch-through from the application of the electronic shutter pulse.
