Abstract: A pixel array comprise a green pixel comprising a first green optical filter and a first clear filter, a red pixel comprising a red optical filter and a first special filter, a blue pixel comprising a blue optical filter and a second special filter, and an IR pixel comprising an IR optical filter and one of a second green optical filter and a second clear filter, where the first special filter suppresses a transmission of IR at a stopband centered at 850 nm at a first IR minimum transmission, and the second special filter suppresses a transmission of IR at the stopband centered at 850 nm at a second IR minimum transmission, and where the first minimum IR transmission is different from the second minimum IR transmission.

Abstract: A wireless typoscope displays an enhanced image of an object to a person with poor vision. The wireless typoscope includes an image capture unit having (a) a camera for capturing an image of the object and (b) a wireless transmission unit, and a handheld image display unit having a touch screen. The image capture unit wirelessly transmits the image to the handheld image display unit which enhances and displays the image on the touch screen.

Abstract: Systems and methods for calibrating a 360 degree camera system include imaging reference strips, analyzing the imaged data to correct for pitch, roll, and yaw of cameras of the 360 degree camera system, and analyzing the image data to correct for zoom and shifting of the cameras. Each of the reference strips may include a bullseye component and a dots component to aid in the analyzing and correcting.

Abstract: An example wireless camera system includes a camera, a wireless network adapter, an acoustic receiver, and a processor. The camera is configured to acquire image data and the wireless network adapter wirelessly communicates the image data over a wireless network. The acoustic receiver is configured to receive an acoustic signal containing configuration data and the processor configures the network adapter to communicate over the wireless network using the received configuration data of the acoustic signal.
