A method is provided for modifying an image. The method comprises displaying an image, the image comprising a portion of an object; and determining if an edge of the object is in a location within the portion. The method further comprises detecting movement, in a member direction, of an operating member with respect to the edge. The method still further comprises moving, if the edge is not in the location, the object in an object direction corresponding to the detected movement; and modifying, if the edge is in the location, the image in response to the detected movement, the modified image comprising the edge in the location.

A camera and method which selectively applies image content adjustments to elements contained in the image material. By way of example, the method involves registration of user touch screen input and determination of the arbitrary extent of a specific element in the captured image material at the location at which touch input was registered. Once selected, the element can be highlighted on the display, and additional user input may be optionally input to control what type of adjustment is to be applied. Then the element within the captured image material is processed to apply automatic, or user-selected, adjustments to the content of said element in relation to the remainder of the captured image. The adjustments to the image element may comprise any conventional forms of image editing, such as saturation, white balance, exposure, sizing, noise reduction, sharpening, blurring, deleting and so forth.

A rotating cutting head catheter for passage through chronic total occlusions or other refractory atherosclerotic plaque from diseased arteries is disclosed. The catheter's rotating cutting head is designed to reside safely within an outer protective sheath when not in use. The outer protective sheath contains one or more helical grooves or slots, and the cutting head contains protruding blades or projections that fit into these helical grooves or slots. Application of torque to an inner catheter or wire attached to the cutting head applies spin to the cutting head, and the force of the sheath's helical grooves or slots against the cutting head's protruding blades or projections advances the cutting head outward from the protective sheath. Once extended, the cutting head may now rotate freely. The device may use a guidewire to direct the cutting head to the desired position.

Catheter system and method for boring through blocked vascular passages

Catheter-based Optical Coherence Tomography (OCT) systems utilizing an optical fiber that is positioned off-axis of the central longitudinal axis of the catheter have many advantage over catheter-based OCT systems, particularly those having centrally-positioned optical fibers or fibers that rotate independently of the elongate body of the catheter An OCT system having an off-axis optical fiber for visualizing the inside of a body lumen may be rotated with the body of the elongate catheter, relative to a handle portion The handle may include a fiber management pathway for the optical fiber that permits the off-axis optical fiber to rotate with the catheter body relative to the handle The system may also include optical processing elements adapted to prepare and process the OCT image collected by the off-axis catheter systems described herein

A fluorescent type of green light source (36) of a semiconductor in a light source apparatus (13) for an endoscope (11) includes a blue excitation light source device (44) and green emitting phosphor (47). The blue excitation light source device (44) emits blue excitation light LBe. The green emitting phosphor (47) is excited by the blue excitation light LBe, and emits green fluorescence LGf. A dichroic filter in a dichroic mirror (80) cuts off the blue excitation light LBe from an emission spectrum of mixed light of the blue excitation light LBe and green fluorescence LGf from the fluorescent type of green light source (36). Thus, illumination light with the emission spectrum of a target can be stably supplied without influence of the blue excitation light LBe to a light amount of blue light LB from a blue light source (35) of a semiconductor.

Raw image data obtained by shooting is thinned at a thinning rate, which is determined in accordance with a shooting scene, to produce simple raw image data. The thinning rate is determined such that necessary information for proper checking is maintained and unnecessary information for checking is thinned. Image correction is performed for the simple raw image data with predetermined processing parameters, and this data is converted into a simple display image to be shown on a monitor. An operator observes the simple display image to change the processing parameters. Whenever the processing parameters are changed, the image correction is performed for the simple raw image data with the changed processing parameters to update the simple display image. For the raw image data, image correction is performed with the finally determined processing parameters.

This optical tomographic imaging system comprises an optical path length adjustor configured to set a first reference position of a measurement depth direction to an inner edge of a measurement range by adjusting an optical path length of a reference light, and an optical path length switching unit having a preset optical path length that provides a second reference position differing in measurement depth from the first reference position by a predetermined amount and configured to change the optical path length of the reference light or the optical path length of the reflected light adjusted by the optical path length adjustor so as to switch between the first reference position and the second reference position. This system is capable of measuring a measurement region of interest at high resolution, regardless of the position (depth) of the measurement region of interest, in an SS-OCT employing a wavelength-swept light source.

A digital still camera produces size-reduced image data of a JPEG file, which is converted into printable image data of a TIFF file according to a converting parameter. In the digital still camera, raw image data (CCD-RAW) is produced, corresponds to the JPEG data, and has an unreduced format. Images of the JPEG data are displayed in a playback manner. A customer order of an image among the displayed images to be printed is processed. JPEG data associated with the image of the customer order is adjusted according to a standard adjusting parameter. The standard adjusting parameter is modified into a first adjusting parameter. Raw image data associated with the image of the customer order is converted into TIFF data by image conversion according to the first adjusting parameter and/or a standard converting parameter being preset.
