An optical device may include a pinhole array layer having pinhole array apertures therein. The pinhole array layer may have a first side to be directed toward incoming electromagnetic (E/M) radiation, and a second side opposite the first side. The optical device may also include image sensors. Each image sensor may include image sensing pixels adjacent the second side of the pinhole array layer. The optical device may also include mirrors. Each mirror may be associated with a respective image sensor and respective pinhole array aperture defining a camera. Each mirror may reflect incoming E/M radiation passing through the respective pinhole array aperture to the respective image sensor. A respective baffle may be between adjacent cameras.

Techniques for updating zoom properties of corresponding salient objects are described that support parallel zooming for image comparison. In an implementation, a zoom input is received involving a salient object in a digital image in a user interface. An identification module identifies the salient object in the digital image and zoom properties for the salient object. A detection module identifies a corresponding salient object in at least one additional digital image and zoom properties for the corresponding salient object in the at least one additional digital image. An adjustment module then updates the zoom properties for the corresponding salient object in the at least one additional digital image based on the zoom properties for the salient object in the digital image.
