Embodiment
Below, the desirable embodiment to the present invention's the image display with automatic image pattern is elaborated with reference to the accompanying drawings.
Fig. 2 is the block diagram of the present invention's the image display with automatic image pattern.
As shown in Figure 2, signal of video signal input block 100 receives signal of video signal from devices such as video cards.And 110 pairs of the scaler signal of video signal by above-mentioned signal of video signal input block 100 inputs convert the frame unit that can show to, make its signal that is synchronized with display unit 150 input then and transmit.
In addition, from the signal of above-mentioned scaler 110 outputs, by transmitting again after LVDS TX 120 compressions.And by the signal after the above-mentioned LVDS TX120 compression, be input to LVDSRX 130 once more and carry out decompress(ion).
In addition, instruction that the user imported and desired image mode, it can be selected with reference to the menu that is presented on the display unit 150 by instruction input block 160.Then, control module 170 will be exported control signal corresponding according to selected instruction.
Here, above-mentioned control module 170 reaches the horizontal/vertical synchronization signals (H-Sync/V-Sync), the form of input image is confirmed that imports by above-mentioned signal of video signal input block 100 according to the user instruction by above-mentioned instruction input block 160 inputs.And then the output control signal corresponding, thereby just can export demonstration to relevant signal of video signal.
In addition, above-mentioned scaler 110 is according to the control signal of above-mentioned control module 170, to handling, so that above-mentioned signal of video signal shows according to user's selected image mode in above-mentioned instruction input block 160 by the signal of video signal of above-mentioned signal of video signal input block 100 inputs.In addition, the reference value of each image mode that the user selects by above-mentioned instruction input block 160 is stored in the above-mentioned storer 141 with the form of lookup table.Above-mentioned format converter 140 is handled the signal through above-mentioned LVDS RX 130 decompress(ion)s, so that it can show by display unit 150 according to the control signal of above-mentioned control module 170 outputs.Here, for above-mentioned storer 141, it is made of nonvolatile storer (EEPROM).
In addition, the image mode to setting by above-mentioned instruction input block 160 transmits to Port Multiplier 180 according to the control signal of above-mentioned control module 170 outputs.The reference value of having set that above-mentioned Port Multiplier 180 receives in the above-mentioned storer 141 by above-mentioned format converter 140, then it is compared with the signal of video signal of handling through above-mentioned scaler 110, export corresponding adjusted value according to its difference to above-mentioned phase inverter 190 then, thereby just can realize the brightness of above-mentioned display unit 150 is regulated.
For example: the user can select own desirable image mode by above-mentioned instruction input block 160.Then, just can carry out different settings to contrast (Contrast), brightness (Brightness), color (Color) equivalence of having set according to different patterns.
That is to say that supposing to have for the pattern that the user selects: image, comfortable image, soft several modes such as image clearly.The reference value of its each pattern can be represented by following table:
[table 1]
Image clearly | Comfortable image | Soft image | |
Contrast | 95 | 90 | 80 |
Brightness | 60 | 50 | 40 |
Color | 60 | 50 | 40 |
Above-mentioned phase inverter 190 is according to the control signal of above-mentioned control module 170 outputs, the signal of video signal of being imported is compared with the reference value in being stored in above-mentioned storer 141, according to relatively result the value of input signal of video signal is regulated then, so that it is identical with reference value in being stored in above-mentioned storer 141.
Therefore, in the foundation embodiments of the invention,, select user's automatic image pattern in order to set to the desired image mode of user, and then to above-mentioned format converter 140 and Port Multiplier 180 transmission corresponding instruction, thereby the adjusting brightness of above-mentioned phase inverter 190 is set.Then, again the value of above-mentioned setting is compared with the reference value in being stored in above-mentioned storer 141.Then,, the value of above-mentioned setting is adjusted, so that it is identical with reference value in being stored in above-mentioned storer 141 again according to comparative result.
By above-mentioned description, relevant speciality personnel can carry out various change and modification fully in the scope that does not depart from the technology of the present invention thought.
Therefore, technical scope of the present invention is not limited to the content on the instructions, must determine its technical scope according to interest field.
