Classification: CPC H  G | IPC G  H

Claim 16:
17. An apparatus, comprising:
a memory device coupled to a controller;
an image sensor coupled to the controller;
a sensor block coupled to the controller; and
the controller coupled to the memory device, the image sensor, and the sensor block, wherein the controller is configured to:
cause the sensor block to operate in a first mode to allow the image sensor to receive inputs, wherein a number of polarizers in the first mode allow light to pass through the number of polarizers unpolarized, wherein the number of polarizers includes a first polarizer, a second polarizer, a third polarizer, and a fourth polarizer configured in a stack; and
cause the sensor block to operate in a second mode to inhibit the image sensor from receiving the inputs, wherein at least two of the number of polarizers in the second mode polarize light that passes through the number of polarizers.
