摘要： Techniques are disclosed herein for estimating parameters of a model of a thermal print head for use in performing thermal history control. In particular, techniques are disclosed for use in conjunction with a thermal print head having a plurality of print head elements and an associated heat sink. A sensitivity of a thermal print media to a temperature of the heat sink is identified. A sensitivity of the thermal print medium to a temperature of the plurality of print head elements is then identified based on the identified sensitivity of the thermal print medium to the temperature of the heat sink. Techniques are also disclosed for deriving conditions on estimated parameters of the print head model that determine the stability of the resulting thermal history control algorithm. Techniques are also disclosed for iteratively optimizing the values of those parameters.

摘要： Techniques are disclosed for correcting the exposure of a digital image. An exposure predictor may be generated based on a set of images for which ground truth data are known. After identifying an optimal set of features, the exposure of the digital image may be corrected by extracting values of the selected optimal features from the image, using the predictor to predict a desired exposure correction for the image, and correcting the exposure of the image by the predicted desired amount. Exposure correction is based on a model that relates intensity of light in the world to the RGB digits of the digital image. The model comprises a gamma function that models the response of a typical monitor and a S-shaped curve that compresses the large dynamic range of the world to the small dynamic range of the RGB digit space.

摘要： A model of a thermal print head is provided that models the thermal response of thermal print head elements to the provision of energy to the print head elements over time. The thermal print head model generates predictions of the temperature of each of the thermal print head elements at the beginning of each print head cycle based on: (1) the current ambient temperature of the thermal print head, (2) the thermal history of the print head, (3) the energy history of the print head, and (optionally) (4) the current temperature of the print medium. The amount of energy to provide to each of the print head elements during a print head cycle to produce a spot having the desired density is calculated based on: (1) the desired density to be produced by the print head element during the print head cycle, and (2) the predicted temperature of the print head element at the beginning of the print head cycle.

摘要： In one aspect of the invention there is disclosed a multicolor thermal imaging system wherein different heating elements on a thermal print head can print on different color-forming layers of a multicolor thermal imaging member in a single pass. The line-printing time is divided into portions, each of which is divided into a plurality of subintervals. All of the pulses within the portions have the same energy. In one embodiment, every pulse has the same amplitude and duration. Different colors are selected for printing during the different portions by varying the fraction of subintervals that contain pulses. This technique allows multiple colors to be printed using a thermal print head with a single strobe signal line. Pulsing patterns may be chosen to reduce the coincidence of pulses provided to multiple print head elements, thereby reducing the peak power requirements of the print head.

摘要： A strobe diffuser attachment for a camera, includes a diffuser body adapted for attachment to a camera, a pair of spaced diffuser lenses mounted in the diffuser body and adapted to be located in front of a range of different integral strobe locations for a camera attached to the body, wherein the pair of diffuser lenses are adapted to serially diffuse light emitted from an integral strobe of a camera attached to the body. A distance measurement device uses a pair of light beams which intersect at a repeatable distance from the diffuser body to readily enable positioning of an object to be photographed at that repeatable distance.

摘要： There is described a method for forming lenses having substantially no optical power. The method includes forming, via in situ polymerization, a layer of non-uniform thickness of an optically clear, high scratch-resistant polymeric material on the convex surface of the lens. The lenses provided by the method are characterized by having maximum thickness in the central region of the lens and gradually diminishing thickness radially towards the periphery of the lens.

摘要： A compact light weight printhead capable of direct quasi contact printing includes an OLED Color Filter structure deposited onto a substrate. The OLED-Color Filter structure includes an OLED structure emitting over a broad range of wavelengths and color filter arrays that selectively transmit radiation in different distinct ranges of wavelengths. The printhead is designed for contact or quasi-contact printing printing, without additional optical elements. The printhead design ensures that the desired pixel sharpness and reduced crosstalk is achieved. Two possible different arrangements for the printhead are disclosed. One arrangement includes at least one array of OLED elements and at least one color filter array. Each color filter array in this arrangement includes at least one triplet if color filters, and each element in each the triplet is capable of transmitting radiation in a distinct wavelength range different from the distinct wavelength range of the other two color filters in the same triplet. In a second arrangement, the printhead includes at least one triplet of arrays of individually addressable Organic Light Emitting Diode (OLED) elements and at least one triplet of arrays of color filter elements, each OLED array in the triplet being in effective light transmission relation to the light receiving surface of one color filter array in the triplet thereby constituting an OLED-Color filter array set. In this second arrangement, each color filter array in each triplet has elements that are capable of transmitting radiation in a distinct wavelength range different from the distinct wavelength range of the other two arrays in the triplet.
