Abstract

Disclosed is a lens system for removable connection to a portable programmable device which includes a camera. This lens system can be arranged in various embodiments to modify the field of view experienced by this camera, and in specific embodiments can modify the direction of this cameras field of view. The device can also be used to provide software capable of executing on a portable programmable device, in addition to providing a light pipe to redirects light used as a photographic flash in applications where it modifies the direction of view of a camera.

Claims

1-56. -56. (canceled)

57. A lens system adapted for removable connection to a portable programmable device which includes a camera, the lens system including

an optical system arranged to re-direct by a desired angle the direction of view of the camera of a portable programmable device to which the lens system is attached, the optical system including

a reflective element for changing the direction of view of the camera, and an objective lens assembly, and

a housing for said optical system, said housing arranged to locate the optical system in alignment with the camera of a portable programmable device

wherein the housing positions optical systems reflective element between the objective lens assembly and the camera.

58. A lens system as claimed in claim 57 wherein the optical system redirects the direction of view of the camera by a substantially 90 degree angle.

59. A lens system as claimed in claim 57 wherein the reflective element of the optical system is a mirror.

60. A lens system as claimed in claim 57 wherein the reflective element of the optical system is a prism.

61. A lens system as claimed in claim 57 wherein the housing is releasable attachable to the portable programmable device.

62. A lens system as claimed in claim 57 wherein the housing is formed by a case that grips all or part of the portable programmable device.

63. A lens system as claimed in claim 57 wherein the housing includes a snorkel lenses assembly adapted to allow rotation of the optical system.

64. A lens system as claimed in claim 57 which includes at least one light pipe, wherein the light pipe includes

a body which provides an optical waveguide, and

an inlet arranged to receive light into the body, and

at least one outlet arranged to emit light from the body.

65. A method of image capture and modification implemented through the execution of computer readable instructions configured to execute on a portable programmable device which includes a camera system, said camera system being associated with a removable lens system, the application including executable instructions arranged to execute the steps of

receiving an input image from the camera system captured using the lens system, and

applying at least one correction function to the input image, and

outputting at least one corrected image,

wherein said correction function is adapted to improve the quality of the image captured by the camera.

66. A method of image capture and modification as claimed in claim 65 which includes the additional preliminary step of identifying the portable programmable device and/or camera system.

67. A method of image capture and modification as claimed in claim 65 wherein said correction function is arranged to correct for the effects of optical deficiencies of the lens system.

68. A method of image capture and modification as claimed in claim 65 further characterised by the additional steps of

receiving at least one input orientation indication from one or more orientation sensors associated with the programmable device,

applying at least one translation function to an input image

outputting at least one corrected image

wherein an input parameter of said translation function is the orientation indication received from an orientation indication sensor.

69. A method of image capture and modification as claimed in claim 65 characterised by the additional steps of

receiving at least one input orientation indication from one or more orientation sensors associated with the programmable device,

applying at least one translation function to an input image

generating a cropped image by selecting a sub-region of a translated image

outputting said cropped image

wherein an input parameter of said translation function is the orientation indication received from an orientation indication sensor.

70. A method of image capture and modification as claimed in claim 68 wherein a translation function includes an image rotation function.

71. A method of image capture and modification as claimed in claim 65 wherein a correction function reduces the effect of optical aberrations associated with the lens system.

72. A method of image capture and modification as claimed in claim 65 wherein a correction function corrects for geometrical distortions associated with the lens system.

73. A computer readable medium bearing computer readable instructions for a portable programmable device, said instructions being arranged to execute on a portable programmable device which includes a camera system, said camera system being associated with a removable lens system, the instructions arranged to execute the steps of

receiving an input image from the camera system captured using the lens system, and

applying at least one correction function to the input image, and

outputting at least one corrected image,

wherein said correction function is adapted to improve the quality of the image captured by the camera.

74. A computer readable medium bearing computer readable instructions as claimed in claim 73 which includes the additional preliminary step of identifying the portable programmable device and/or camera system.

75. A computer readable medium bearing computer readable instructions as claimed in claim 73 which executes the additional steps of

receiving at least one input orientation indication from one or more orientation sensors associated with the programmable device,

applying at least one translation function to an input image

generating a cropped image by selecting a sub-region of a translated image

outputting said cropped image

wherein an input parameter of said translation function is the orientation indication received from an orientation indication sensor.
