A method for rendering a three-dimensional (3D) image and an image outputting device that is configured to perform the method are provided. The method includes: loading a 3D screen; calculating a ray density of each region of the loaded 3D screen in order to generate a rendering map; rendering the 3D screen by using the rendering map; and outputting the rendered 3D screen.

Method of rendering 3D image and image outputting device thereof

Provided are an image processing apparatus and method for decreasing an amount of power consumed to display an image. The image processing apparatus includes: an input interface configured to input image data; at least one processor configured to obtain an output pixel value by adjusting at least one selected from luminance, resolution, and precision regarding a portion of the image data; and an output interface configured to output image data including the obtained output pixel value.

Image processing method and apparatus for operating in low-power mode

A shadow rendering method is provided. The shadow rendering method includes emitting radial light to an object so that a shadow area for the object generated by a three-dimensional modeling is projected; determining a portion of the shadow area as a penumbra area for the object; and rendering a penumbra for the object to the penumbra area.

Shadow rendering apparatus and control method thereof

An apparatus for testing an object includes a test chamber, a guiding member, testing units and a transferring unit. The test chamber is configured to receive the object. The guiding member is arranged extending along a first direction in the test chamber. The testing units are movably connected to the guiding member to test electrical characteristics of the object. The transferring unit is arranged in the test chamber to load the object into one of the testing units and unload the object from one of the testing units. The testing units may be transferred to a position for repair without suspension of the apparatus. The object may be tested using another testing unit while the other testing unit is being repaired.

A cartridge for an information recording medium includes a cartridge case, an opening cover, detachably mounted to a rear side opening of the cartridge case, for enabling the information recording medium to be withdrawn or inserted with respect to the cartridge case, and a holding unit for preventing movement of the information recording medium by supporting the information recording medium when the information recording medium is received and/or withdrawn into/from the cartridge case. The holding unit includes a pair of elastic pressure parts, elastically formed on the opening cover, for elastically supporting the information recording medium to prevent movement of the information recording medium when the opening cover is not attached to the cartridge case, and a release unit for releasing the pair of elastic pressure parts when the opening cover is attached to the cartridge case so that the information recording medium is rotatable in the cartridge case.

An automatic tilt compensator senses and automatically compensates for a disc deformation while an optical recording and/or reproducing apparatus operates. The automatic tilt compensator of an optical recording/reproducing apparatus has a disc deformation detecting section for sensing a deformation direction and a deformation degree of a disc seated and rotated on a disc rotation unit of a deck base and for outputting a predetermined signal, and a level adjustment section for elevating and lowering a pair of guide shafts movably supporting a pickup unit on the deck base while being operated by the signal from the disc deformation detecting section, to thereby adjust the level of the pickup unit corresponding to the deformation degree of the disc. According to this, the level of the pickup unit according to the deformation direction or the deformation degree of the disc can be automatically adjusted while the optical recording/reproducing device is operated. Accordingly, even when a deformed disc is inserted, since the level of the pickup unit is automatically adjusted according to the deformed disc, errors in recording and reproducing information caused due to the deformed disc can be remarkably reduced.

An adaptor includes a sensor hole to be open/closed, and a method and an apparatus drive the adaptor. The adaptor includes at least one sensor hole determining the size of a disc received in an adaptor body which is received via a disc holder. The disc holder includes an elastic press extended therefrom and elastically support the disc, preventing a movement of the disc until the disc holder is inserted into the adaptor body. Further, a release is disposed on the adaptor body to release the disc from the elastic press when the disc holder is inserted into the adaptor body. A method for driving the adaptor includes determining whether the sensor hole is open; and determining the type of device inserted into a disc drive. The type of drive inserted into the disc drive is determined by the adaptor accommodating an 8-cm disc when the sensor hole is open, while a cartridge accommodates a 12-cm disc when the sensor hole is closed. An apparatus for driving the adaptor includes a sensing switch to be selectively inserted into the sensor hole of the inserted adaptor to be turned on/off and transmit the corresponding signal regarding the open/closed state of the sensor hole to a microcomputer.

A cartridge for an information recording medium includes a cartridge case, an opening cover, detachably mounted to a rear side opening of the cartridge case, for enabling the information recording medium to be withdrawn or inserted with respect to the cartridge case, and a holding unit for preventing movement of the information recording medium by supporting the information recording medium when the information recording medium is received and/or withdrawn into/from the cartridge case. The holding unit includes a pair of elastic pressure parts, elastically formed on the opening cover, for elastically supporting the information recording medium to prevent movement of the information recording medium when the opening cover is not attached to the cartridge case, and a release unit for releasing the pair of elastic pressure parts when the opening cover is attached to the cartridge case so that the information recording medium is rotatable in the cartridge case. The information recording medium is accommodated and withdrawn with respect to the cartridge case, by attaching/detaching the opening cover with respect to the cartridge case while supporting the disc with the holding unit. Accordingly, a user does not need to touch the information recording medium directly to replace the information recording medium, and damage to the information recording medium caused by the user's fingerprints, scratches, etc., is prevented.

A cartridge having a case which accommodates a disc, the case having a receiving opening and a longitudinal opening extending from the receiving opening through which an information reproducing apparatus chucks and accesses the disc, a shutter movably mounted on the case, the shutter opening/closing the longitudinal opening and a part of the receiving opening, and a covering part moved by the movement of the shutter so as to completely close the open part of the receiving opening which is not closed by the shutter. When the cartridge is not in use, the receiving opening and the longitudinal opening are not exposed, while the same are open when the cartridge is in use so that the information is recorded/reproduced on/from the disc accommodated therein. In addition, the cartridge can be compact-sized.
