An image display unit and a method of detecting an object which are capable of reliably detecting an object with a simple structure irrespective of use conditions are provided. Invisible light is emitted from a screen of a display portion. The invisible light reflected from a target object which comes in contact with or close to the screen is received on the screen. On the basis of the received invisible light, the target object is detected. Thus, the target object can be reliably detected without influence of the display state of the display portion, and influence of use conditions such as surrounding circumstances (the case where it is bright or dark). Moreover, for example, it is not necessary to separately arrange a component such as a touch panel, so the image display unit can be achieved with a simple structure.

Image display unit and method of detecting object

A display device and a display method are provided in which the influence of the outside light can be removed easily, in the case where light-emitting and light-receiving are performed in parallel and simultaneously. In the case where an image-display and a light-receiving are performed simultaneously or alternately on a display surface of the display device, processing of making the display surface emit light to display an image is performed; light entering the display surface is received, which is the light-receiving of two times of a state in which the light-emitting for display use is being performed (step S) and of a state in which light is not emitted (step S); and a state in which the display surface is touched or approached is detected based on the detection of a difference in the quantities of received light of the two times (step S).

Display device and method providing display contact information based on an amount of received light

An information processing apparatus for controlling a display device, includes: an acquisition unit acquiring an image of a subject formed in an image capture area made of a plurality of pixels performing an image capture operation, based on outputs from pixels constituting an image capture area; a transmitter transmitting data of the acquired image data to an other information processing apparatus controlling an other display device having the same construction as the display device; a receiver receiving data of an image of other subject transmitted from the other information processing apparatus; and a display controller displaying the image of the other subject in a display area based on the received image data.

Information processing apparatus and method, recording medium, program, and display device

A display device that is capable of displaying predetermined display information in each of a plurality of display areas includes a setting unit for setting display control information that represents the position and size of the display area and the switching of the display information for when a predetermined event is detected, based on user inputs; and a display control unit for controlling one display including the multiple display areas such that the display information is displayed in each of the multiple display areas, based on the display control information set by the setting unit. Upon detection of the event, the display control unit switches the position or size of the display area where the display information for the detected event is displayed based on the display control information.

Display device, display method, and program

An information processing apparatus and method disclosed herein allows information to be communicated intuitively and readily. The information processing apparatus including, production element for producing a plurality of first graphic images representative of output data to be outputted to a different information processing apparatus; display element for successively displaying the first graphic images produced by the production element; detection element for detecting a plurality of second graphic images representative of input data inputted from the different information processing apparatus in response to successive display of the second graphic images on the different information processing apparatus; and acquisition element for acquiring the input data based on the second graphic images detected by the detection element.

Information processing apparatus and method, recording medium and program

Shutter for an optical disc cartridge

A disc recording and/or reproducing apparatus, employing a disc cartridge housing a disc with a diameter of approximately 64 mm, small enough to be placed in a user's pocket for easy transportation. The disc recording and/or reproducing apparatus has a spindle motor and optical pickup device mounted such that a surface of the spindle motor and the pickup is fitted into the base to reduce the thickness of the apparatus.

Disc recording and/or reproducing apparatus and disc reproducing apparatus

An optical disk recording and/or reproducing apparatus employing a disk cartridge having accommodated therein an optical disk not more than 80 mm in diameter as a recording medium, the apparatus including an outer casing having a length not larger than 112 mm, a width not more than 89 mm and a height not more than 31 mm which encompasses a cartridge loading section for loading the disk cartridge, a driving unit for rotationally driving the optical disk accommodated in the disk cartridge, an optical pickup unit and means for transporting the optical pickup unit across inner and outer peripheries of the optical disk driven rotationally by the disk driving unit for recording information signals on or reproducing information signals from a recording surface on the optical disk, a magnetic head unit for generating an external magnetic field based on information signals to be recorded, the magnetic head unit and the optical pickup unit being connected together for movement in unison therewith and arranged facing each other on opposite sides of the optical disk accommodated in the disk cartridge, controlling means for controlling a movement of the magnetic head unit perpendicular to the recording surface of the optical disk as a function of the types of the disks accommodated in the disk cartridge loaded into the apparatus, and a disk loading unit for loading the disk cartridge onto the cartridge loading section and loading the optical disk accommodated in the disk cartridge onto the disk driving unit.

Disk cartridge which has a recess whose height indicates the type of

A disc cartridge is provided which may be positively loaded in position on cartridge loading section within a recording and/or reproducing apparatus and in which a cartridge main body may be fabricated easily. The disc cartridge is provided with a cartridge main body in which a disc for recording information signals, a shutter member movably mounted on the cartridge main body, and a groove into which may be introduced a shutter opening member is adapted for opening the shutter member and which is provided on the cartridge main body along the direction of movement of the shutter member. A clearance is formed in the groove for clearing the shutter opening member.

Disc cartridge with clearance groove

A method for interchangeably using a first and second type of disc cartridge. The first type of disc cartridge has a shutter suitable for being made from bent sheet metal. The second type of disc cartridge has a shutter suitable for being made from synthetic material, such as a synthetic resin.

Method of interchangeably using two disc cartridges with two different

An optical disc includes a disc base plate of a light-transmitting synthetic material having a recess for mounting a magnetic plate, and a holding part, integral with the disc base plate, for loosely holding the magnetic plate mounted in the recess with respect to the disc base plate. It is possible with the present optical disc to prevent distortion of the disc base plate otherwise caused by the difference in thermal expansion coefficients of the two components to inhibit double refraction of the disc base plate otherwise caused by such distortion to maintain good recording/reproducing characteristics.
