Abstract
The invention relates to a cellphone and a method for displaying image by grayscale variation, in which the cellphone comprises a keyboard input device, a display device, a storage device for storing the contents needed to be displayed, a baseband processor for receiving the original data input by the keyboard and outputting the grayscale information to the display device according to a grayscale algorithm after retrieving corresponding displaying data from the storage device. The baseband processor comprises the following parts: a display control device which provides needed logical signal and controls the work of display device; an algorithm implementing device which acquires the new data content obtained from the grayscale algorithm according to the original data content; an image generator which generates the grayscale image displayed on the screen. The method of the invention mainly via the use of keyboard to receive the input information by the user, processing the original image data by the baseband processor, storing the image data, generating the image data of grayscale display, operating the display device, and displaying the grayscale data. The invention is convenient to be used by chromates and provides a new displaying style for normal people, thus improving the practicability of cellphone.
Description
Technical field
The present invention relates to moving communicating field, especially, come display image by variation of image grayscale to having the communication terminal of color LCD.Also can be applicable to other and have color LCD equipment.
Background technology
The display system of existing communication terminal, great majority all have colored output function, but, to some specific crowd, for example the achromate can not correctly differentiate shades of colour owing to self-defect, can't see the image on the screen clearly, this mobile phone and method that just need convert thereof into the grey scale change demonstration is helped them.
Goal of the invention
The objective of the invention is to overcome the defective that exists in the prior art, propose a kind of mobile phone that can come display image by grey scale change.
Another object of the present invention is to overcome the defective that exists in the prior art, proposes a kind of method of coming display image on mobile phone by grey scale change.
, comprising: finger-impu system according to the mobile phone of the gray scale variation display image of nationality according to the present invention; Display device; Memory storage is used for storing all the elements that need be presented on the screen; Baseband processor is used to receive the raw data that keyboard is imported, and extracts corresponding video data from described memory storage, then according to grey order algorithm, gray level information is outputed on the display device;
Described baseband processor comprises:
Display control unit provides needed logical signal of display device and data, the work of control display device;
The algorithm implement device draws new data content according to original data content according to grey order algorithm; Video generation device is with generating the gray scale image that need be presented on the screen.
A kind of method that shows gray scale image on mobile phone that proposes according to the present invention comprises step:
A, use keyboard are accepted user's input by controller;
B, use baseband processor generate raw image data by described controller;
C, use baseband processor are by described controller storing image data;
D, use baseband processor generate the view data that GTG shows by described controller;
E, use baseband processor are by described controller function display device;
F, use baseband processor show luma data by described controller.
Compared with prior art, the present invention has changed display mode single in the device for mobile communication, has both made things convenient for colour blindness crowd's use, also is a kind of new display styles for the normal person simultaneously, has strengthened the practicality of mobile phone.
Description of drawings
Fig. 1 is a block diagram of the present invention.
Embodiment
Described baseband processor can be used the baseband processing chip in the mobile phone, and described memory storage can be that (SDRAM, cache), and static memory (Flash), described display device can be TFT LCD to dynamic storage.
Keyboard controller normally links to each other with baseband processor, can send to baseband processor to user's input like this.
Baseband processor is received after the data, and they are stored in the internal storage location, and with generating view data, these data may be independent, also may be continuous.
Color image data is kept in the Memory Controller Hub, and baseband controller draws the maximum gray that display device can be supported according to algorithm, and different display device GTGs are inequality, and baseband controller must at first calculate correct GTG.
Baseband controller constantly obtains color data from memory storage, then according to algorithm, draw final gradation data, and be saved in the memory storage, prepares to show.
Baseband controller also needs according to different display device, adopts different control modes, and sending needs data presented.
After display device obtains data, finish final work, the user is seen effect.
The color sum that each display device can show is how much to be decided by its employed figure place.
For example, certain display device is used 16 and is represented a kind of color, and its color sum that can show is exactly 16 powers of 2 so, equals 65536; If use 18 to represent a kind of color, its color sum that can show is exactly 18 powers of 2 so, equals 262144.
All colours all is by red, and is green, and blue three kinds of basic colors are formed, and the figure place addition of these three kinds of colors is exactly the total bit of display device.For example, the meaning of RGB565 is red 5 bit representations that use, green 6 bit representations that use, and blue 5 bit representations that use, three's addition is exactly 16.
If use GTG to represent, use 16 equally, its institute can gray-scale displayed, for redness be exactly 5 idempotents of 2 in 32, for green be exactly 6 idempotents of 2 in 64, be exactly that 5 idempotents of 2 are in 32 for blueness; Use 18, the gray scale of three kinds of colors of red, green, blue all is that 6 idempotents of 2 are in 64.
The present invention has enriched the mobile communication equipment image display pattern, has expanded the changeability of system, meets customer need better.
