20080279084 | Image Reader - An LPF performs low-pass filtering for a light reception signal responsive to return light received by an optical pickup. A comparator makes a comparison between the level of the signal output from the LPF and a predetermined threshold value and outputs a high or low pulse signal MIR. A system control section determines the pulse signal MIR for each predetermined dot region. If the pulse signal MIR output from the comparator is high, the system control section writes “1” into buffer memory; if the pulse signal MIR is low, the system control section writes “0” into the buffer memory. The pixel string data recorded in the buffer memory is transferred to a host and an image responsive to pixel string data is displayed on a display. | 11-13-2008 |
20090147631 | Optical Disk Image Forming Device, Optical Disk Image Forming Method and Optical Disk - When an image is formed on an optical disk, an optical disk image forming device reads information written in an information area of the optical disk. When a reflection preventing process is applied to an image forming area of the optical disk, the optical disk image forming device corrects at least one of a laser power or a focus gain in accordance with information about the image forming areawritten in the information area. Thus, the optical disk image forming device can form the image with a clear brightness and a good visibility on the image forming area of the optical disk without allowing a rainbow-color to appear or a face or a background to be reflected due to the interference of light. | 06-11-2009 |
20090268578 | Optical Disk Processing Apparatus - An optical pickup is opposed to an inner-radius portion of an optical disc that is set, and pits (a modulation signal) are read by applying laser light for a DVD to the inner-radius portion. The read-out modulation signal is decoded by inputting it to a CD decoder. If decoded disc information includes particular verification data, the optical disc is judged to be a legitimate optical disc of a particular type and formation of a visible image on the label surface is permitted. | 10-29-2009 |
20100245530 | Optical Disk Image Drawing Method - An optical disk image drawing method includes: rotating the optical disk by a spindle motor; reading a predetermined information recorded on a track of a data recording layer; detecting a predetermined position on the track based on the read predetermined information; measuring a position of the spindle motor in a rotating direction using the detected predetermined position as a reference position; changing a focus position of the laser beam to the image drawing layer; starting forming the visible image on the image drawing layer from a predetermined position of the spindle motor in the rotating direction relative to the reference position based on the measured position of the spindle motor in the rotating direction; and sequentially moving an optical pick-up in the radial direction synchronously with the rotation of the spindle motor to proceed to form the visible image. | 09-30-2010 |
20110025916 | External Equipment Controlling Apparatus - An external equipment controlling apparatus includes: a connecting unit, connected to an external equipment via an interface to input/receive data into/from the external equipment, the external equipment to which audio data is input and which performs an acoustic process to a sound corresponding to the audio data and causes a speaker to emit the sound; an audio data outputting unit, operable to generate the audio data, and operable to output the audio data to the external equipment; an identification information acquiring unit, configured to acquire identification information for specifying the external equipment from the external equipment; a program acquiring unit, configured to acquire a control program corresponding to the external equipment specified by the identification information from a server via a network; a video data outputting unit, operable to generate video data for displaying a setting screen for setting the acoustic process on a displaying unit, and operable to output the video data to the displaying unit; and a controlling unit, by executing the control program, configured to control a content of the video data and to control the external equipment by setting the acoustic process in response to command information to be input. | 02-03-2011 |

20090135708 | Optical disk system, optical disk recording apparatus, image drawing method and optical disk - The invention provides an optical disk system having at least: an optical disk comprising, on a substrate having pre-pits, an image-recording layer capable of drawing an image by irradiating a laser light; and a reading device which reads information included in the pre-pits by a return light of the laser light when the laser light having a wavelength of in a range of 630 to 680 nm is irradiated to the pre-pit of the optical disk. The pre-pits have a shortest pit length in a range from 0.6 to 0.9 μm being formed on the substrate. The invention further provides an optical disk recording apparatus, an image drawing method and an optical disk which utilize the optical disk system. | 05-28-2009 |
20090290459 | Optical Disk Image Forming Device and Optical Disk Image Forming Method - When an optical disk image forming device forms an image on an optical disk, the image forming device reads information of kinds of coloring matters used in an image forming area from information described in an information area of the optical disk. Then, the optical disk image forming device reads from a table laser power strength information corresponding to the information of the kinds of the coloring matters and a maximum linear velocity (Nx) at the time of forming the image and applies a laser beam having this laser power strength to form the image on the image forming area of the optical disk. Thus, since the discoloration of the coloring matter in the image forming area is always saturated, the image having a constant contrast can be formed on the image forming area of the optical disk. | 11-26-2009 |
