Abstract

Un sensor de imágenes con un arreglo de pixeles que incluye por lo menos un pixel. El sensor puede incluir un circuito que está conectado al pixel y provee un valor de pixel de imagen final que es una función de una señal de salida muestreada generada a partir del pixel. El valor de pixel de imagen final es fijado hacia un valor de reserva si la señal de salida muestreada excede un umbral. La imagen final puede ser función de una primera, segunda y/o tercer imagen y un campo que provee información si la imagen final incluye una primera relación de exposición, una segunda relación de exposición y/o una tercera relación de exposición.
