摘要: An imaging module is described that acquires images of objects and outputs a digital image of the objects that is corrected for aberrations and flaws due to design, manufacturing constraints and variability, and, the local environment (temperature and humidity). The imaging module includes memory to store adjustment parameters, environmental sensors, and, a computing device that processes the raw acquired image into a corrected processed image. The imaging module is used with a test apparatus to calibrate the imaging module and calculate empirically determined correction factors that are stored in memory within the imaging module.

摘要: A lens mount design is presented. The mount can be used on a variety of imaging systems but is targeted at small camera systems such as might be used on mobile phones, cameras, sports cameras, computers and computer peripherals where interchangeable lenses are currently not common place. Embodiments include different attachment mechanisms, environmental barriers, electrical connections, a serial number marking system on the replaceable lens body and methods for using the lens mount and system.

摘要: Low ghosting wide-angle lens designs are presented. The dimensions and materials are selected such that the lens has a field of view of at least 145 degrees, f# of 2.2-2.9 and all secondary images of an object imaged on the image plane are focused such that they fall either outside of the image plane thus having a relative intensity that is less than 10−4 times the intensity of the primary image.In one embodiment a set of conditional expressions are all met. In another embodiment the conditional expressions are all met and the conditional expressions related to the physical size of the lens is narrowed. In another embodiment five and seven element designs are produced.

摘要: A ultra-wide angle objective lens comprising a first group having a first lens element having a convex object surface facing the object and a concave image surface facing the image plane, and a second aspheric lens element, the second aspheric lens element having a varying power that is negative at its vertex; and that increases positively with radial distance from the vertex. A second group has at least one lens element and a positive power. A third group has at least a first and a second lens element and a positive power. The ratio of the total track to the focal length satisfies the condition that TT/fo= f*θ, where h(θ) is the image height formed by an off-axis chief ray having a field angle θ, and f is the effective focal length of the lens.

摘要: An lens assembly has a having a height TT and a focal length f0 and three lens elements with first and second surfaces, the first surface of each element facing the object. The first lens element has a positive power and a focal length f1. The second lens element 20 is a aspheric lens, the first surface being concave and facing the first lens element second surface. The second lens element second surface being an aspheric surface. The third lens element first surface is convex having a radius of r1 and the second surface having a radius r2 with |r2|>|r1|. The first, second and third lens elements are shaped are formed to obtain a ratio of f1/f0 in the range of 0.5 to 2.0 and a TT/DI
