摘要:
A tone display method for displaying a tone of an image in a display system which divides a time width of a field of an image signal into a plurality of weighted subfields and controls operation of the subfields. The tone display method includes the steps of coding the image signal in the plurality of weighted subfields the plurality of weighted subfields including a plurality of most significant subfields having respective weights which are substantially equal to one another, and a plurality of less significant subfields having respective weights each of which is less than each of the weights of the most significant subfields, a sum of all of the weights of the less significant subfields being greater than each of the weights of the most significant subfields, the coding being chosen from a plurality of codings all representing substantially a same tone level when a tone level of the image signal is not less than each of the weights of the most significant subfields, and displaying the image signal coded with the chosen coding.

A intra-field time division tone display method for dividing the time width in a field of a TV signal into a plurality of subfields in the pixel storing time direction and displaying the TV image by controlling the presence or absence of light emission of the subfields and an apparatus therefor, wherein there are at least two subfields (most significant subfields) whose luminant time widths are longest and almost equal and when it is assumed that the tones are displayed in the ascending order starting from the lowest level of tone in light emission of the subfields, the tone of a TV image signal is displayed under a rule that two or more light emissions are not started from the aforementioned at least two most significant subfields at the same time, accordingly the dynamic false contour noise of a moving image followed by movement of the viewing point can be reduced remarkably and a moving image of high image quality and high quality can be obtained.

A method displays a halftone image on a display unit by using a frame division technique that divides each frame of the halftone image into subframes each having a specific sustain discharge period to provide a specific intensity level. The method differs the position of the halftone image on the display unit from subframe to subframe in each frame. The method is capable of displaying dynamic halftone images without intensity level disturbance, smears, or false color contours.

A method of displaying a dynamic halftone image on a display panel made of pixels divides each frame of the image into subframes and turns on and off the subframes. The method includes the steps of finding a line of pixels that simultaneously display a specific intensity level in a frame and another specific intensity level in the next frame, counting the number of pixels in the line, selecting corrective pulses, which turn on/off corresponding subframes to enable/disable corresponding intensity levels, according to the counted number and a change in the specific intensity levels between the frames, and adjusting original display signals for the pixels in the line according to the corrective pulses, respectively. The method eliminates halftone disturbance and false color contours from the image even if the moving speed of the image on the display panel is high.

An air conditioning apparatus and a refrigerant quantity determination method are provided, whereby a refrigerant quantity can be determined in a simple and accurate manner without compromising the reliability of a compressor. A refrigerant circuit (10) has a compressor (21), an outdoor heat exchanger (23) that functions as a condenser, an indoor expansion valve (41, 51), an indoor heat exchanger (42, 52) that functions as an evaporator, an indoor unit interconnection pipe (4b, 5b), a liquid refrigerant connection pipe (6), a gas refrigerant connection pipe (7), and an outdoor unit interconnection pipe (8). A controller (9) performs liquefaction control for liquefying refrigerant and placing the refrigerant in a portion extending from the indoor expansion valve (41, 51) to the outdoor heat exchanger (23). The controller (9) directly or indirectly regulates the flow rate of refrigerant flowing through a liquid bypass circuit (70) from a liquid reserving portion (Q) toward the gas refrigerant connection pipe (7). A liquid level detection sensor (39) detects at least one of either a volume of liquid refrigerant in the portion where liquid refrigerant accumulates and a physical quantity equivalent to the volume.

A washer nozzle (1) includes a nozzle body (2), a nozzle tip (11) which is mounted within the nozzle body (2), and a nozzle holder (15) having a head portion (9) for storing the nozzle body (2) and also has a supply portion (10) for supplying a cleaning liquid. The nozzle body (2) has a partitioning plate (4) configured to partition the spray orifice into two-tiered parts, and also has a guide portion (3) for guiding liquid spray. The nozzle body (2) of the washer nozzle (1) is configured so that the relative angle between upper liquid spray and lower liquid spray can be changed by making the length (a) of a guide region variable, the guide region extending in the direction of the center axis (c) of the nozzle body from the front end surface of the partition plate to the front end surface of the guide portion (3).

A terminal device 500 that is connected to a key distribution device 400 via a network, and in which a recording medium device 600 is mounted, the key distribution device 400 being for distributing a title key necessary for use of content, the recording medium device 600 being for storing therein the content and the title key. The recording medium device 600 and the key distribution device 400 perform mutual authentication and share shared keys that are identical to each other. The terminal device 500 comprises: a reception unit that receives an encrypted title key from the key distribution device 400, the encrypted title key being the title key encrypted with the shared key of the key distribution device 400; and a transfer unit 513 that transmits the encrypted title key to the recording medium device 600. Upon completion of the mutual authentication between the recording medium device 600 and the key distribution device 400, the reception unit and the transfer unit 513 refrain from any involvement with communication data except reception and transmission thereof, the communication data being exchanged between the recording medium device 600 and the key distribution device 400 with use of the shared keys.

A memory card includes a storage unit storing key information and version information in association with the key information, the key information and the version information being issued by a key issuing authority and the version information indicating a version of the latest revocation list that has been issued when the key information is generated. A revocation list receiving unit receives a revocation list having a version; and a version verification unit compares the version of the revocation list received by the revocation list receiving unit and the version information. When the version of the revocation list is older than version information, processing by a revocation list writing unit is prohibited.

A shift register includes a plurality of stages of unit circuits each including a flip-flop. Each of the unit circuits generates, by obtaining a sync signal in accordance with an output from the flip-flop, an output signal. The flip-flop includes a first switch and a second switch and a latch circuit for latching a signal supplied thereto and outputting the signal as the output from the flip-flop. A first shift direction signal is supplied to the latch circuit via the first switch, and the second shift direction signal is supplied to the latch circuit via the second switch. In each unit circuit other than those of the first and last stages, an output signal from a previous stage is supplied to a control terminal of the first switch, and an output signal from a subsequent stage is supplied to a control terminal of the second switch.
