摘要： A method for video recording includes converting the first portion of a series of optical signals to a first video data by an image sensor in a video recording device and subsequently converting the second portion of the series of optical signals to a second video data without interruption by the image sensor. The first video data is stored in a first long-term data storage till the first long-term data storage is substantially full. The second video data is stored in a secondary memory. The first long-term data storage is removed from the video recording device. The second video data is copied from the secondary memory to a second long-term data storage.

摘要： A high-speed digital photographic printing system and method includes image-specific backprinting and automatic tracking and sorting of printed jobs. The system includes one or more photographic printers, where each printer can have a different printing rate. A scheduler schedules printing orders to the different printers. The printer-independent image rendering is conducted asynchronous to the printing to maximize the printing throughput. In some embodiments, the rendering image processor does the vast majority of the image processing and outputs a printer-independent data file (generally much larger than the source image data file) that requires little if any further data manipulations or processing in the exposure unit. A photographic printing method and system for producing prints in response to input digital images includes a high-speed exposure unit that exposes a photosensitive material coated on a substrate in response to the input digital image, a chemical processor unit that receives and processes the exposed photosensitive material to form visible dye images on the substrate, a backprinting unit that receives the substrate having the visible dye images and prints information on the opposite surface of the substrate to the dye image, and a cutting unit that produces separate sheets of printed images after the backprinting unit prints information.

摘要： Printer and method adapted to reduce variability in ejected ink drop volume. A print head includes a plurality of nozzles integrally attached to the print head, each nozzle being capable of ejecting an ink droplet therefrom. At least one of the nozzles has an undesirable characteristic producing ink droplets of non-nominal volume. A waveform generator is connected to the nozzles for generating a plurality of waveforms to be supplied to the nozzles, so that the nozzles eject the ink droplets in response to the waveforms supplied thereto. Each waveforms has a plurality of pulses controlling ink droplet volume. A controller is provided for controlling the waveforms supplied to the nozzles and for transmitting the waveforms to the nozzles in order to eject the ink droplets so as to compensate for the non-nominal volume by controlling the number of pulses in the waveform. In this manner, all nozzles produce ink droplets of nominal volume regardless of physical or electrical variations between nozzles.

The cartridge includes a housing for receiving a plurality of receivers, each receiver including field-driven particles in a matrix that can change reflective density in response to an applied electric field which intersect at positions corresponding to pixels and the housing defining alignment features for insertion into the receiving structure which receives and positions an inserted cartridge. The housing further includes electronic interconnecting circuitry for connection between the addressing circuitry and a receiver after a cartridge has been inserted in the receiving structure for permitting the application of voltages at the pixel positions across the field-driven particles at particular locations in the receiver corresponding to pixels in the stored image to produce an image in the receiver in the cartridge.

摘要： An ink jet print head is provided that includes a nozzle plate having an outer metal layer having nozzles for ejecting ink drops, and a coating of a non-wetting polymer chemically bound over the outer surface of the metal layer of the plate. Preferably, the polymer is a block polymer having a head that includes the chemical group that chemically bonds with the outer metal layer, and a tail that is hydrophobic. The resulting polymer coating prevents inks from pooling, drying, and creating deposits which would otherwise impede or clog the ink jet nozzles. The chemical bonding between the non-wettable polymer and the metal surface creates a highly durable polymeric layer that resists being wiped off during both printing and head cleaning operations.

摘要： Imaging apparatus and method for providing images of uniform print density. The apparatus includes a print head having a plurality of nozzles containing ink. Each nozzle has an image forming characteristic, such as print density, associated therewith. A heater associated with each nozzle is in heat transfer communication with the ink for heating the ink, so that, as the ink is heated, its surface tension relaxes. As surface tension relaxes, static back-pressure acting on the ink ejects the ink from the nozzle. A voltage supply unit is provided for supplying a voltage pulse to each of the heaters for activating the heaters and a controller interconnects the heaters and the voltage supply unit for controlling the voltage pulse. Controlling the voltage pulse causes the image forming characteristic for each nozzle to be altered to the extent that the image forming characteristics for all the heaters will become uniform. In this regard, the controller includes a memory unit capable of informing the controller of the voltage pulse duration to be applied to each heater for obtaining uniform image forming characteristics. Alternatively, the memory unit may inform the controller of the pulse amplitude to be applied to each heater for obtaining uniform image forming characteristics. Therefore, either the voltage pulse amplitude or the voltage pulse duration applied to each heater is controlled such that the image forming characteristics (e.g., print densities) of all nozzles are uniform.
