Abstract: One embodiment of the present invention relates to a method and a apparatus for converting a three-dimensional image using depth map information. The apparatus comprise a depth map estimation unit which estimates the depth map information for each pixel present in each frame of input image data, a depth map application unit which moves each pixel by the depth map information in the X-axis direction, a 3D image interpolation unit which, when a blank pixel occurs in the frame due to the movement, forms an interpolated pixel in the blank pixel by applying a weight to adjacent pixels of the blank pixel, and a 3D image rendering processing unit which renders a left-eye image and a right-eye image to which the interpolated pixel is applied.

Abstract: An apparatus for driving a scanner includes a driving motor which is rotated in both directions, a driving gear which is driven by the driving motor, a driving pulley which rotates a timing belt coupled to the scanner body, a reduction gear which is engaged with a gear portion of the driving pulley, a power transmitting unit for directly transferring a rotational force of the driving gear to the driving pulley or transferring the rotational force through the reduction gear to the driving pulley, where, when reading a colored image, the driving force is decelerated and then transferred to the driving pulley under the same speed of the driving motor as a case of reading a black-and-white image, in accordance with the rotating direction of the driving motor.

Abstract: A method for correcting scanning errors in a shuttle type of a scanner, including the steps of scanning a pattern sheet on which pattern data having a specified shape are recorded. Errors for decline of the pattern data are corrected by using the pattern data having a straight line among the scanned pattern data having the specified shape. Then, errors for distance between bands are corrected by using the pattern data having the specified shape among the pattern data of which the errors for decline are corrected. Accordingly, since the errors for decline and the errors for distance between the bands can be corrected by using a computing program, there is an advantage in that correcting the errors of the pattern data is very simple. A further advantage is in that even if the scanner is subjected to an impact from its exterior, correcting the errors for decline and the errors for distance between the bands can be promptly performed.

Abstract: A printer that prevents the drying of nozzles of an unused micro injecting device in an inkjet printer provided with a plurality of micro injecting devices, during printing, and a control method thereof. The object of this invention is to prevent drying of nozzles without moving the micro injecting device to a maintenance location and spraying a small amount of ink during a printing operation. The printer includes a plurality of micro injecting devices provided with a plurality of nozzles that receive nozzle drive data to drive the nozzles and spray ink; a plurality of micro injecting device drivers that provide the nozzle drive data for controlling the spraying of the nozzles and making the ink inside the nozzles move up and down; a carriage that is mounted with the plurality of micro injecting devices and reciprocates side to side above the paper; a control section that drives the unused micro injecting device among the plurality of micro injecting devices to make the ink move up and down.

Abstract: A motor driving device for changing the current of the driving control signal of the carrier motor according to the consumption quantity of the ink in the inkjet printer includes a detector of an ink consumption quantity for outputting a comparative signal when a present ink quantity stored within the ink cartridge is less than the reference ink quantity, through counting each ink drop signal produced by at least one ink drop formed in each of a number of nozzles of the inkjet printer, to provide a count signal for comparison with a reference signal indicating the reference ink quantity, a voltage generator for outputting a motor driving control voltage having a variable voltage according to whether the comparative signal is produced by the detector, and a motor controller for outputting a plurality of phase control signals each having associated therewith a different driving current for driving the carrier motor according to the motor driving control voltage and according to at least one of first and second

Abstract: A method of transmitting a printer control file from a host computer to a printer includes the steps of: checking if a printer control file that is in the same format as stored in a non-volatile memory, has been amended; and if the printer control file is amended, storing the amended printer control file. When this process of storing the printer control file is complete, or if the printer control file has not been amended, then the printer control file is read. The read printer control file is transmitted to the printer.

Abstract: A control system of a step motor and a method thereof are capable of evenly maintaining a traveling distance and a torque in a moving section, especially in an accelerating section, by limiting a start excitation phase or a final stop phase to a specific phase, even though an excitation and the torque are unevenly generated due to an imbalance in a step angle generated during the manufacturing and/or assembly of the step motor.

Abstract: A method for sensing separation of a carriage from a home position and compensating the home position by using a program stored at a microprocessor of an ink jet printer includes a home position separation sensing process which has the steps of: checking whether or not the ink jet printer is in a stop state and the carriage is placed at the home position; checking whether or not the carriage placed at the home position is separated from the position by sensing the state change of a photo sensor; and setting a flag according to the state change of the photo sensor, and a home position separation state compensating process which has the steps of: checking whether or not a flag has been set; if it is checked that the flag has been set, counting time to maintain the present state for a predetermined time; resetting the home position if the counted time exceeds the predetermined time; checking whether or not an ink cartridge is attached to the carriage; if it is checked that the ink cartridge is attached to the ca
