How to display images on pager and pager that can display images

The present invention relates to a wireless pager capable of displaying a picture, and more particularly, to a wireless pager capable of displaying a picture while changing a picture in a certain order in response to a specific call signal.

Calling system is a known technique. Typically, this technique includes a wireless transmitter and a mobile pager for transmitting a coded call signal indicative of the pager being called. The wireless transmitter is accessible to the mobile pager through the telephone network and the wireless communication network. In order to reach a designated mobile pager, people press an ID number representing the mobile pager, such as pressing a telephone number in normal wired communication, to generate a coded call signal. Once the call signal occurs, the radio transmitter is excited and transmitted to all mobile pagers that are within range of the transmitter. Each mobile pager has an ID number each coded to respond to a different call signal, so that only the pager with a code corresponding to the code of the transmitted call signal is excited. The pager generates an acoustic tone or responds to its corresponding call signal by another appropriate signal. As soon as the call receives a call signal, it responds according to a series of actions to receive additional information from the transmitter.

This additional information includes the numeric or textual information required for the response to the caller.

However, there is a limit to the display of numbers or letters alone, and even if they are represented by numbers or letters, you must already promise what the letters or signs mean, and you are more likely to forget them as more of them are promised. Many.

Accordingly, it is an object of the present invention to provide an image display pager that can be easily understood by the other party without using numbers or letters.

It is another object of the present invention to provide an image display pager that allows the other party to easily understand an image displayed using a small number or letter.

Another object of the present invention is to simply provide a method for displaying an image on a pager.

It is still another object of the present invention to provide an image display radio pager that can display an image changed by a specific call signal, so that the call can be known by a specific call number.

Still another object of the present invention is to grow an image by a specific call signal sent by another person, so that the number of times that a specific call signal is sent can be maintained, thereby maintaining an intimacy with the sender of the specific call signal. There is provided an indication pager.

A radio pager that achieves this object is a call receiver for displaying a message included in the signal on a display means when receiving a signal including a pre-assigned address number, comprising: means for extracting specific data from the received signal; Comparison means for comparing the extracted specific data with previously stored data, memory means for storing first image information in a first order, second image information in a second order, and the specific data; Whenever the pre-stored data matches, the first image information is converted in the first order, and when there is no specific data among the received data, or when the specific data and the pre-stored data do not match, the currently displayed data is displayed. Display means for displaying a message including conversion means for converting image information from the image into a second order.

The pager further includes determining means for determining whether a period without specific data has elapsed, and when more than a preset period of time, processes the image in the second order from the currently displayed image.

In addition, the pager further includes a number limiting means for limiting the number of times the first image can be converted in a first order during a predetermined period.

In such a pager, the predetermined period of time may be set to work that is set to work.

Furthermore, such a pager is a radio pager that receives a call signal from a radio base station and displays the received call signal. The radio pager is a memory page in which image data is stored and an image data code included in the call signal received from the radio base station. Detecting means for detecting, reading means for reading out an image corresponding to the image data code detected by the detecting means into the memory means, and display means for displaying the image read out by the reading means for displaying an image can do.

In such pagers, specific data or image data codes are detected by the location of the received data.

Therefore, such a pager receives a call signal from a radio base station and displays the received call signal, detecting whether the received call signal contains specific data, and receiving time of receiving the specific data stored in the memory. Changing to a reception time of new specific data, displaying a current display on the display device according to a first predetermined order when specific data is detected, and receiving specific data for a preset period of time. Otherwise, the image is displayed by displaying the current display on the display device in a second predetermined order.

Such a pager may, if necessary, allow the pager to include first and second displays and the image to be displayed on the second display.

In addition, the predetermined period can be set to days, and the period can be calculated by changing the date.

6C to 6G show the form of the damagot which is stored in FIG. 4A and can be expressed on the display screen of the pager by the image data.

The POCSAG code, which is a code format for the digital calling system proposed to the UK Postal Service in 1976, consists of one preamble signal followed by one or more contiguous arrangements, as shown in FIG.

Each batch is divided into a 32-bit sync code section and eight frames of 64 bits each. Each frame consists of two codewords or two idle codewords, and each codeword consists of 32 bits. . Therefore, the signal can be transmitted by eight frames.

In the present invention, as shown in Fig. 3, the modulation wave signal is transmitted in the format of the following arrangements B1, B2, ... of the preamble word PW, and an image identification code is added and transmitted. For example, if the caller presses the number corresponding to the image to send the image, it is coded and inserted, where "x ... x y2 y1 y0" (x is the call number and y is the unknown code number) is inserted. do. In the present invention, a bit added after the call number from the base station is transmitted as 4 bits. However, these bits may be transmitted by adding more bits if necessary.

Pagers are already well known and, if necessary, wide area systems can be used.

The functional block diagram of the pager shown in FIG. 1 operates according to the principles of the present invention. The call signal, including the call message sent from the base station, is received at antenna 105 and connected to mixer 108 through amplifier 107. Signals from local oscillator 109, including voltage controlled oscillator 110, phase detector 111, phase locked loop 112, and divider 113, are also coupled to mixer 108 to combine with the call signal and generate an intermediate frequency signal. This intermediate frequency signal is provided to demodulator 116 via a two-pole crystal filter 114 and a low noise amplifier 115. The demodulator provides a clock signal and the NRZ data sent to microprocessor 118 for further processing non-return-to-zero (NRZ) forms a continuous stream of data. This includes the synchronization of bits and the synchronization of words for use by the microprocessor in framing incoming message words. The measurement of the received signal strength is also provided to the microprocessor 118 from the demodulator 116 through the analog-to-digital converter 117.

Operational control of the pager unit is provided by the microprocessor 118. This is accomplished through some control function performed by microprocessor 118. NEC part No. Commercially available microprocessors, such as the 80C50, may be used as the microprocessor with proper programming. Once the microprocessor 118 matches the data string sent from the base station, it begins to interpret the data to determine if an appropriate control message is included.

The microprocessor also performs the control actions required for the pager to respond to control messages as well as call messages. This control operation may include a command to cause the pager to operate over a plurality of channels.

The microprocessor 118 also controls the operation of several internal components that make up the pager. The parts are all directly connected to the microprocessor. The memory unit 121 for the microprocessor 118 includes a programmable read only memory (PROM) 122, a random access memory (RAM) 123, and a read only memory (ROM) 124.

PROM 122 is a nonvolatile memory that stores specific information for each pager unit operating in the calling system. This information includes the initial indication channel's data indication, home system, ID number and serial number. The control program for microprocessor 118 is provided by ROM 124. The ROM 124 also stores image data shown on the display unit 126 as shown in Fig. 4A with an address number. Thus, when the caller sends a specific number to display the pre-committed image on the display 126b, the microprocessor decrypts it and displays it on the display 126b according to the program stored in the ROM 124. FIG.

126a is a display unit generally made of LEDs that display call numbers. However, if necessary, other early display means, for example, LCD, etc., may be configured, and the display portions 126a and 126b may also be configured on one screen.

In addition, a function selection is given to the unit 128 for the user to arrange some operations of the pager unit. Included in this function selector unit 128 are on-off and mode switches to excite the pager unit respectively and select normal or quiet mode of operation. When this control operation is performed, a page message is provided if there is a page message indication in memory. Otherwise only the confirmation tone is provided to the user.

The indicator of the pager unit for alerting the user immediately upon receipt of the message includes an acoustic alarm such as beeper 125 and a visual alarm such as indicator 126. In normal call mode, both the acoustic and visual alarms respond to the call signal. However, in silent call mode, the acoustic alarm is not excited and only the visual alarm responds. Once the pager unit recognizes the page message, the visual and acoustic alarms are excited for about 10 seconds. External page alarm reset Terminates this alarm over control (excited by the user) or over time.

Also included in the function selector unit 128 is a Roam system select switch, which allows the user to select the channel set of the system to which a connection is required. However, this selection is only possible in roaming mode. During normal operation, when the pager unit operates in the Home region, the pager unit selects a service system from the information stored in nonvolatile memory 122. The configuration and operation of such a pager is a general configuration, and the techniques described in US Patent Nos. 4,518,961, 4,713,808, 4,849,750, 5,162,790, 5,327,321, PCT Patent Publication W091 / 06190, and the like can be applied to the present invention.

The display unit 126 is configured not only to display normal numbers and / or displays, but also to display an image or display a specific picture by a specific wireless signal.

The power of the pager is provided to a power source 120 including a battery. A battery life detection circuit is included in the power supply 120 to provide an indication to the microprocessor 118 when the battery voltage drops below a predetermined level.

When operating power is applied to the pager unit, it performs an internal diagnostic test on the microprocessor 118 and other components. A check mark signals the successful completion of this test. However, if the battery test detects subnormal battery conditions, and all other tests are successful, subnormal battery status / confirmation is provided to the user. Once successfully powered, the pager unit begins the process of selecting the appropriate setup channel.

When the channel selection process is complete, the love call (called 'love call') located after the call number is detected and stored in the buffer. For example, if the call signal received from the base station is "x ... x0 0 1 0" and "0 0 1 0" is detected, it is stored in a buffer and the received call signal is "x ... x 1 0 1 1 "," 1 0 1 1 "is stored in the buffer" 1 1 0 0 "if" x ... 1 x 0 0 ". The microprocessor reads out the image from the memory means in which the image data is stored with reference to the love call corresponding to this buffer, and transmits the image to the display means for display. Such image data is stored in FIG. 4A as described below.

The code for finding the image data, as shown in Fig. 2, is selected from the calling party and transmitted from the base station with the call signal and message.

The image data is coded and stored in ROM 124 shown in FIG. 1, for example, the muffler of FIG. 6 is stored at address 01 of FIG. 4A, an umbrella is stored at 02, and an SOS image is stored at 0B. In addition, image data corresponding to (1) in FIG. 7 is shown at address 98, image data corresponding to (2) at address 99, image data corresponding to (3) at address 9A, and address 9B at address 9A. Image data corresponding to (4) th, image data corresponding to (5) th at address 9C, image data corresponding to (6) th at address 9D, and image (7th) at address 9E Image data corresponding to the (8) th address is stored at the address 9F, image data corresponding to the (9) th address is stored at the address A0, and image data corresponding to the addresses A1, A2, and A3 are stored in the same manner. The image data may be various types of data, for example, image data representing a growth process of a chick, a dinosaur, and the like.

Therefore, when the channel selection process is completed and the code stored in the buffer is detected by detecting the love call located after the call number, the image corresponding to the specific code, that is, the love call is read from the buffer and displayed on the display unit 126b.

In this case, it is assumed that specific data is detected by position, but this may be indicated by a specific bit.

In particular, the present invention may further include a time setting means, if necessary, to display the image data only for a predetermined time.

In addition, if necessary, it may further include a control means for designating the display position for displaying an image from another person.

The present invention can also display and grow, for example, Tamagotchi by a specific love call (which is called 'specific love call').

Specific image data indicating the growth process of this damagot is stored from the address 98 of the ROM shown in Fig. 4A.

The growth of the damagotchi proceeds by the detection of a specific love call or password located after the call number after the channel selection process is completed. For example, if the code detected from the call signal received from the base station and stored in the buffer is "1 1 1 1", the growth step of the damagotchi is performed.

First, if the data stored in the buffer is the specific data as a result of processing the radio call signal, the microprocessor recognizes the data for growing the damagot and first reads the damagot image data number stored in the RAM. If the address of the ROM storing the image data of Tamagotchi is not read out, the image data and time indicating the beginning of the Tamagotchi are stored in the RAM and displayed on the display device indicating the first stage of the Tamagotchi. If the address of the image data is read out, the address of the stored image data is increased by one, and then the image data of Tamagotchi corresponding to this address is read out and transmitted to the display means for display. Stores the received time in RAM. Then it waits for the call signal containing the specific code.

When there is a call signal again, a specific love call is detected and stored in the buffer, and the code shows that the growth of Tamagotchi is called 'the first growth process of Tamagotchi: the process of FIGS. 6C to 6E. In the case of a specific code indicating a, the address of the image data stored in the RAM is increased again, and then the image data corresponding to this address is read out and transmitted to the display means for display. Is stored in RAM. It waits for a call signal containing a specific code.

However, if there is no call signal containing a specific code even after a certain period of time, another process of growth of tamagotchi when there is no specific code from the address stored in RAM, such as loneliness or decay ( This is branched to Tamagotchi's 'second growth process': the process shown in Fig. 6f), image data of the corresponding address is read out and transmitted to the display means for display, and the address and the specific code are received. One time is stored in RAM. Then it waits for the call signal containing the specific code. If there is no call signal containing a specific code even after a certain time has elapsed, it branches from the current address stored in the RAM, proceeds to an address indicating the second growth process, and reads it to display on the screen. And wait a certain time. If there is no data containing the specific code, the address of the currently stored ROM is changed to follow the second growth process, the image data corresponding to this address is read out and transmitted to the display means for display. The time at which the code was received is stored in RAM. Then it waits for the call signal containing the specific code.

However, if a call signal is detected and a love call is detected, and the code is a specific love call, the branching process proceeds from the address indicating the second growth process stored in RAM to the first growth process, and then the address indicating the first growth process. The image data corresponding to the data is read out and transmitted to the display means for display, and the RAM and the time when the address and the specific code are received are stored. Then it waits for the call signal containing the specific code.

Using this method, the damagot is continuously branched, that is, branched from the first growth process to the second growth process, or branched from the first growth process to the first growth process. You can grow.

5 is a flowchart illustrating a process of processing such a specific signal, FIG. 5A is a flowchart for processing a love call and a specific love call (a specific love call refers to a love call for growing a tamagotchi), 5B is a flowchart illustrating a second growth process of damagotchi. First, referring to FIG. 5A, starting from block 310, a bit signal stored in a buffer is read in block 312, and a block call 314 determines whether a love call is received. If it is a love call, flow proceeds to block 320 to process the love call and to block 316. If not at block 314, proceed to block 316 as is if not a love call. In block 316, if the bit stored in the buffer read in block 312 is a specific love call, the process proceeds to block 322 to store the time of the love call in RAM, and the process proceeds to block 324 to process the specific love call. At block 316, if there is no specific love call, or if the bit stored in the buffer is not a specific love call, then the process proceeds to block 318 indicating only the call reception and ending.

FIG. 5B is a flowchart illustrating a process of processing a love call in FIG. 5A.

First, in the love call in FIG. 5A of the love call, the process proceeds to block 3202, where the image data corresponding to the number extracted from the bits stored in the buffer of block 312 is read from the ROM, and the process proceeds to block 3204 by the image data read from the ROM. Display an image on the screen. The process proceeds to block 3206 to determine whether a predetermined time has elapsed, and if the predetermined time has not elapsed, the image display is continued. If the predetermined time has elapsed, the process proceeds to block 3208 to delete the display and proceeds to block 3210 to end. .

5C is a flowchart illustrating a process of processing a specific love call.

First, if it is a specific love call in Fig. 5A of the love call, the flow proceeds to block 3402 to determine whether the number of specific love calls of the day is within the set number of times. If the number is greater than or equal to the predetermined number, the process proceeds to block 3414 and ends. If it is within the number of times set in block 3402, proceed to block 3404 to increase the address of the ROM stored in RAM by 1 to store the new address in RAM, proceed to block 3408 to read image data from the ROM according to the newly set address, and then block 3412. Proceed to display it on the screen.

5D is a flowchart illustrating a process when there is no specific love call for a set time.

First, for the time set in block 362, proceed to block 364 to branch from the address currently stored in RAM to a specific address and set a new one. Proceed to block 366 to read an image corresponding to the newly set address from the ROM, and block 368. Proceed to mark it in the image, then return to block 362. It is determined whether the time set in block 362 has elapsed. If there is no specific love call for the set time to elapse, the process is repeated. If there is a specific love call within the set time, the process proceeds to block 370 and returns to the original original ROM address, that is, the address before branching.

Therefore, according to the present invention, the object of the present invention is not only to display an image that can be easily understood by the other party without using numbers or letters, but also to convert the image into an image even if the other party uses text. By doing so, the other party can easily understand.

Furthermore, such an image display method can additionally display the image without impairing the function of the conventional pager, and furthermore, it is possible to display an image that changes in time.

Further, in the present invention, Tamagotchi is taken as an example, but it is a matter of course that such image data can have various forms as necessary.

None.
