An endoscope comprising: a housing comprising a tubular wall; a camera having an image sensor and being enclosed within said housing and being configured to form image data and to supply the image data to a transmitter, wherein said transmitter is enclosed within said housing and is configured to transmit the image data to an external device; a short-range source enclosed within said housing, to generate short-range light exiting said housing; wherein said short-range source is positioned at a location whereby said short-range light passes through a short-range illumination region of the housing defined by a first intersection of said short-range light with a surface of the housing; a long-range source enclosed within said housing, to generate long-range light exiting said housing; wherein said long-range source is positioned at a location whereby said long-range light passes through a long-range illumination region of the housing defined by a second intersection of said long-range light with said surface of the housing; wherein the short-range illumination region is larger than the long-range illumination region; wherein the short-range source and the long-range source are positioned relative to a pupil of the camera and wherein the pupil has an optical axis that intersects with said housing such that an optical axis intersection point of the optical axis is contained within the short-range illumination region but is located outside the long-range illumination region; and wherein the long-range illumination region is further arranged such that it does not overlap an imaging region of the housing, wherein the imaging region is determined by a field of view, wherein the field of view is defined by a range of angles over which a diagnosable image is captured by the camera in each of a plurality of planes passing through the optical-axis intersection point and the optical axis, wherein an intersection of the field of view with the housing forms the imaging region of the endoscope, and wherein each of the short-range source and the long-range source are located outside the field of view. a housing comprising a tubular wall; a camera having an image sensor and being enclosed within said housing and being configured to form image data and to supply the image data to a transmitter, wherein said transmitter is enclosed within said housing and is configured to transmit the image data to an external device; a short-range source enclosed within said housing, to generate short-range light exiting said housing; wherein said short-range source is positioned at a location whereby said short-range light passes through a short-range illumination region of the housing defined by a first intersection of said short-range light with a surface of the housing; a long-range source enclosed within said housing, to generate long-range light exiting said housing; wherein said long-range source is positioned at a location whereby said long-range light passes through a long-range illumination region of the housing defined by a second intersection of said long-range light with said surface of the housing; wherein the short-range illumination region is larger than the long-range illumination region; wherein the short-range source and the long-range source are positioned relative to a pupil of the camera and wherein the pupil has an optical axis that intersects with said housing such that an optical axis intersection point of the optical axis is contained within the short-range illumination region but is located outside the long-range illumination region; and wherein the long-range illumination region is further arranged such that it does not overlap an imaging region of the housing, wherein the imaging region is determined by a field of view, wherein the field of view is defined by a range of angles over which a diagnosable image is captured by the camera in each of a plurality of planes passing through the optical-axis intersection point and the optical axis, wherein an intersection of the field of view with the housing forms the imaging region of the endoscope, and wherein each of the short-range source and the long-range source are located outside the field of view.
