CPC Class H04N

An optical element is disclosed. The optical element comprises: a first phase shift mask formed on a first optical material and constituted to generate a positive phase shift, and a second phase shift mask formed on a second optical material and constituted to generate a negative phase shift, wherein the phase shift masks are arranged serially on an optical axis, and wherein a refractive index of at least one of the first and second optical materials varies with the temperature at a rate of at least 50×10−6 per degree Kelvin.

A small format factor camera system for mobile devices that provides improved image quality when using accessory lenses. The system may detect an accessory lens attached to the camera, either via sensing technology or by analyzing captured images. The system may analyze image data to determine current alignment (e.g., optical axis alignment, spacing, and/or tilt) of the accessory lens relative to the camera lens, and may shift the camera lens on one or more axes using a mechanical or optical actuator, for example to align the camera lens optical axis with the accessory lens optical axis. The system may also determine optical characteristics of the accessory lens, either via sensing technology or by analyzing captured images, and may apply one or more image processing functions to images captured using the accessory lens according to the determined optical characteristics of the accessory lens.

Devices and methods for managing print jobs on a printing device having a plurality of output media trays are disclosed. The method includes monitoring a print job in an active state, the print job is associated with a predetermined output media tray. The print job being switched from the active state to a held state is detected based on a status of at least one of a first set of printing resources, print input conditions, and print output conditions being negative for the print job. A new incoming print job received at the printing device is identified. A second set of printing resources, print input conditions, and print output conditions are determined for the new incoming print job. Finally, the printing device is triggered to print the new incoming print job for producing prints via an alternate output media tray while the print job is in the held state.
