| 20110248005 | Laser Cutting Method and Equipment, with means for Modifying the Laser Beam Quality Factor by a Diffractive Optical Component - A method of cutting a work-piece to be cut by a laser beam, in which an incident laser beam is generated that has an initial beam parameter product (BPP), given by means of a laser source, preferably an ytterbium-doped or erbium-doped fiber laser source, coupled to at least one optical fiber for conveying the beam. Said incident laser beam is brought to a focusing head comprising at least one optical focusing device. The incident laser beam is focused by means of said optical focusing device, so as to obtain a focused laser beam, and the work-piece is cut by means of the focused laser beam. According to the invention, the quality factor of the incident laser beam is adjusted or modified by means of an optical device designed to be able to modify or vary the BPP of a laser beam so as to obtain a modified focused laser beam having a modified BPP which is different from the BPP of said incident laser beam. Associated equipment for implementing said method. | 10-13-2011 |

| 20090067733 | Byte Representation for Enhanced Image Compression - Various aspects can be implemented to enhance image compression by using a byte representation to reduce the color values and increase redundancy in the color information. In general, one aspect can be a method for enhancing compression of a digital image having a plurality of pixels, each pixel including at least one color component, the method includes obtaining an original number of bits for representing a color value associated with the at least one color component. The method also includes assigning a first reduced number of bits for representing a plurality of case attributes. The method further includes assigning a second reduced number of bits for representing a new color value, wherein the sum of the first reduced number of bits and the second reduced number of bits equals the original number of bits. Other implementations of this aspect include corresponding systems, apparatus, and computer program products. | 03-12-2009 |
| 20090073182 | Two Dimensional Representation Of Color Spaces - Various aspects can be implemented for two dimensional representation of a color space. In general, one aspect can be a method for representing a color space, the method includes obtaining first, second, and third primary colors for the color space. The method also includes providing a first virtual triangle, the first virtual triangle includes a base, a height, and an area defined by height*base/2. The method further includes assigning the first primary color as the height of the first virtual triangle. The method also includes assigning a sum of the second and third primary colors as the base of the first virtual triangle, whereby the intensity of the first primary color can be adjusted by modifying the area of the first virtual triangle. Other implementations of this aspect include corresponding systems, apparatus, and computer program products. | 03-19-2009 |

| 20090060324 | IMAGE ENHANCEMENT AND COMPRESSION - A digital image is compressed by determining a composite color number for each pixel in a digital image represented by a plurality of pixels in a first color space. A first set of color values are extracted from the determined composite color numbers. The first set of color image values are then compacted into a second set of color values according to a predetermined encoding algorithm. A quantity of color values in the second set of color values is smaller than a quantity of color values in the first set of color values. A modified image based on the second set of color values is then generated. A transformation algorithm is then applied to the modified image. | 03-05-2009 |
