    Abstract: An image-pickup optical system includes: a first lens provided near an aperture stop and configured to correct aberration; and a second lens arranged between the first lens and an image sensor and configured to collect light, the first lens being a gradient index lens. The degree of freedom of design of a gradient index lens is higher than that of a lens having a constant refractive index, and a gradient index lens thus has a high potential as a device for a lens. Because such a gradient index lens is employed, it is possible to correct aberration without performing expensive processing such as polishing for example. In other words, as a result, costs may be reduced and image-forming properties may not be reduced at the same time.

  • Patent number: 8754842
    Abstract: An integrated display and camera without simple or compound lenses comprising interleaved light-emitting and light-sensing/photosensor elements. Image formation without use of a simple or compound lens can be obtained via software algorithms operating on light-sensing measurements, for example implementing a two-dimensional deconvolution operation defined by the transfer function imposed by a microoptic array. For example, a microoptic aperture array can be configured to comprise localized optical overlaps which are readily deconvolved or otherwise solved for by an algorithm. Associated microoptic structures can be as simple as apertures or can be more complex, for example including microlenses. Display and photosensor elements can include color capabilities. Light-sensing elements can be similar, nearly, or essentially identical in structure and/or composition to the light-emitting element.

  • Patent number: 8736722
    Abstract: An image capture sharpening subsystem for a digital camera includes a capture sharpening processor and a memory that stores values for a capture sharpening amount. The values for the capture sharpening amount are a function of position on an image sensor of the digital camera. The capture sharpening processor receives a first value for a pixel in an image captured by the image sensor and a position value for the pixel on the image sensor. The capture sharpening processor determines a pixel sharpening amount from the values for the capture sharpening amount stored in the first memory according to the position value. The capture sharpening processor applies a capture sharpening process to the pixel to provide a second value for the pixel according to the pixel sharpening amount and stores the second value in a second memory that provides a sharpened version of the image captured by the image sensor.

  • Patent number: 8730329
    Abstract: This disclosure describes techniques for initially calibrating an image capture device. According to one aspect, the calibration includes calibrating parameters of an image filter for resolving the captured image. The method includes receiving a captured image of a test target and resolving the captured image using a set of initial parameters. A sharpness index of the resolved image is determined without matching the captured image to the test target. The sharpness index is used to minimize a cost function for determining parameters for use by the image capture device.
