The present invention is directed to an unstitched design having the appearance of being stitched or embroidered. A stitched design is digitally imaged, and the digital image used to control dye sublimation printing of a representation of the image onto a desired surface. In one configuration, the surface is a woven textile.

An ink set includes at least two aqueous inks A and B with different colors, the inks A and B used in an inkjet recording method in which the inks A and B are superimposed for formation of a color image, wherein the ink A contains water-dispersible colorant A1 free of a surfactant-based dispersant, and anionic compound A2, and wherein the ink B contains water-dispersible colorant B1 containing a surfactant-based dispersant.

The invention provides a monitoring lens, which comprises a first lens group, a second lens group and a diaphragm, and is characterized in that the first lens group sequentially comprises a first lens with negative focal power, a second lens with positive focal power and a third lens with negative focal power from an object side to an imaging plane; the second lens group comprises a fourth lens with positive focal power, a fifth lens with positive focal power and a sixth lens with negative focal power from the object side to the imaging plane; the first lens, the second lens and the fifth lens adopt a glass spherical lens, the third lens, the fourth lens and the sixth lens adopt a plastic aspherical lens, and the optical centers of the lenses are located on the same straight line. According to the invention, three plastic aspherical lenses are adopted, so that the number of lenses is reduced, and the length, the weight and the manufacturing cost of the lenses are reduced; and the aberration of the lens is enabled to be effectively corrected through matching and combining the lenses of different materials, the reasonable focal power and the air gap distribution, and the monitoring lens has the advantages that small focus shift is generated at high and low temperatures and the like.

A method is disclosed for producing signals representative of an image of a scene including the following steps: providing an image sensor with a lenticular lens pattern thereon, and projecting the image onto the image sensor via the lenticular lens pattern, the image sensor having a pixel element pattern and the lenticular lens pattern having diamond shaped lenticles and being diagonally oriented with respect to the horizontal scanning direction of the pixel element pattern; and producing image-representative signals by reading out signals from the pixel elements of the image sensor.

A method of adjusting exposure settings for a digital camera includes searching at least a portion of the field of view of the camera for pixels having a flesh tone. The flesh tone pixels are analyzed to identify at least one flesh tone spot. Spot metering of the field of view of the camera is carried out such that at least one flesh tone spot is given greater weight than the rest of the field of view. Then, the exposure settings are adjusted based on the spot metering.
