Description

  The present invention relates to an electronic device, and more particularly to an electronic device having an initialization processing function for performing initialization processing at the time of factory shipment.

When the television receiver is turned on, the adjustment mode is determined when the commander is connected, and the user mode is determined otherwise. When the adjustment mode is determined, average initial setting data of each part of the circuit written in advance in a ROM (Read Only Memory) is read, and each part of the circuit is set based on it. Then, when there is a remote control signal from the commander, the adjustment is performed for each television receiver, and the initial setting data (standard value data) of each part of the adjusted circuit is written into the first memory. On the other hand, when it is determined that the user mode, the initial setting data written in the first memory in the adjustment mode is read, and each part of the circuit is set based on this, and thereafter, the user mode processing is performed. The offset value is set with respect to the standard value, and the offset value is written in the second memory. Control by each part of the circuit is performed based on data obtained by adding the standard value and the offset value (see, for example, Patent Document 1).
In the current television receiver, factory workers adjust the initial setting data (standard value data) and adjust the offset value as appropriate to adjust the initial setting data to the optimum value for each set. is doing. At least the offset value among the initial setting data written in the first memory and the offset value written in the second memory is subjected to a predetermined operation by a factory operator at the end of adjustment. It was necessary to reset to the default value.

As shown in the figure, this embodiment includes an antenna 101, a tuner 102, a decoder 103, a video / audio processing unit 104, a display unit 105, a speaker 106, a microcomputer 107, a light receiving unit 108, It includes an interface (I / F) 109, a power supply voltage detection unit 110, a power supply 111, a power supply line 112, a plug 113, an interface (I / F) 114, an operation unit 115, a storage unit 200, and the like. ing.

  The antenna 101 supplies a received signal corresponding to the received radio wave to the tuner 102. The tuner 102 selects a predetermined channel from the received signal supplied from the antenna 101 under the control of the microcomputer 107 and supplies a video / audio signal corresponding to the selected channel to the decoder 103.

  The decoder 103 performs a decoding process on the video / audio signal supplied from the tuner 102 under the control of the microcomputer 107 and supplies the video / audio signal to the video / audio processing unit 104.

  The video / audio processing unit 104 is related to a video such as luminance and hue supplied from the microcomputer 107 to the video signal among the video / audio signals subjected to the decoding processing supplied from the decoder 103 under the control of the microcomputer 107. Based on the standard value and offset value of various adjustment values, a video signal adjusted in luminance, hue, etc. is generated and supplied to the display unit 105, and also supplied from the microcomputer 107 to the audio signal constituting the video / audio signal. On the basis of the adjusted values such as the volume, the strength of the bass, and the strength of the treble, a sound composed of a predetermined bass and treble with a predetermined volume is generated and supplied to the speaker 106. Also, the video / audio processing unit 104 superimposes a video signal corresponding to display data composed of characters, graphics, and the like generated by a character generator 201 described later on the video signal supplied from the decoder 103 under the control of the microcomputer 107. A composite video signal is generated and supplied to the display unit 105.

  The display unit 105 displays the video signal supplied from the video / audio processing unit 104. The speaker 106 outputs the audio signal supplied from the video / audio processing unit 104.

The microcomputer 107 includes a CPU (Central Processing Unit), ROM (Read
It is composed of only memory (RAM), random access memory (RAM), etc., and operates according to a control program stored in the ROM to control each part and execute various processes.

  The light receiving unit 108 receives infrared rays emitted from a remote controller (not shown), converts the infrared rays into corresponding electrical signals, and supplies the signals to an interface (I / F) 109. The I / F 109 supplies control data corresponding to the electric signal supplied from the light receiving unit 108 to the microcomputer 107.

  The power supply 111 generates a direct current of a predetermined voltage from the external power supplied from the plug 113 and supplies the current to each unit via the power supply line 112. The power supply voltage detection unit 110 detects the voltage value of the external power supplied from the plug 113 to the power supply 111 and supplies detection data indicating the detected voltage value to the microcomputer 107.

  The operation unit 115 includes a volume key, a channel key, and the like. The volume key is operated when adjusting the volume, and the channel key is operated when instructing to change the channel. The interface (I / F) 114 supplies key data corresponding to the key operated by the operation unit 115 to the microcomputer 107.

  The storage unit 200 generates and outputs bitmap image data corresponding to various fonts, a character generator 201 for output, an adjustment memory 202 including a non-volatile memory for storing various adjustment values such as video and audio, and various flag data And a flag data storage memory 203 composed of a non-volatile memory.

  The adjustment memory 202 also stores a first adjustment memory area 202a for storing standard values of various adjustment values adjusted for each set before shipment at the factory, and offset values adjusted by the user after shipment. And a second adjustment memory area 202b. The offset value stored in the second adjustment memory area 202b is adjusted by a user in a general home, and is also adjusted as necessary for inspection by an operator in a factory before shipment.

  Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. First, in step S1, the microcomputer 107 determines that the external power supply voltage value (external voltage) supplied from the plug 113 is 100 volts (V) for general households based on the detection data supplied from the power supply voltage detection unit 110. Whether or not (including generally acceptable errors and variations).

  As a result, when it is determined that the voltage value of the external power supply is not 100 volts, the process proceeds to step S 2, and a value 1 is set to a predetermined adjustment mode flag under the control of the microcomputer 107. The value of the adjustment mode flag is supplied to and stored in the flag data storage memory 203 constituting the storage unit 200. Then, it progresses to step S10.

  On the other hand, if it is determined that the voltage value of the external power supply is 100 volts, the process proceeds to step S3. In step S3, it is determined whether the microcomputer 107 has instructed activation in an adjustment mode for setting various adjustment values.

  That is, when a user operates a key for starting in the adjustment mode among the keys of the remote controller (not shown), infrared light corresponding to control data instructing activation in the adjustment mode is emitted from a light emitting unit (not shown). . The infrared light is received by the light receiving unit 108 of the television receiver 100, converted into a corresponding electrical signal, and then supplied to the I / F 109. The I / F 109 supplies control data corresponding to the electrical signal supplied from the light receiving unit 108 to the microcomputer 107. The microcomputer 107 determines whether or not the control data supplied from the I / F 109 is an instruction to start in the adjustment mode. In this case, it is determined that the activation in the adjustment mode is instructed.

  Or, when a power switch (not shown) is operated while a predetermined key (for example, a volume key, a channel key, etc.) of the operation unit 115 provided on the main body of the television receiver 100 is pressed, the power is turned on. Since the key data corresponding to the key is supplied from the I / F 114 to the microcomputer 107, the microcomputer 107 determines that the activation in the adjustment mode has been instructed.

  In step S3, when it is determined by the microcomputer 107 that activation in the adjustment mode is instructed, the process proceeds to step S4, where the value 1 is set to a predetermined adjustment mode flag under the control of the microcomputer 107, and a predetermined initialization flag is set. The value 1 is set to. The values of the adjustment mode flag and the initialization flag are supplied to and held in the flag data storage memory 203 of the storage unit 200. Then, it progresses to step S10.

  When the value 1 is set in the adjustment mode flag, it indicates that the television receiver 100 is activated in the adjustment mode for setting various adjustment values. Further, when the value 1 is set in the initialization flag, it indicates that it is necessary to initialize the offset values constituting the various adjustment values when the user first turns on the power after shipment.

  On the other hand, when it is determined in step S3 that the microcomputer 107 has not instructed activation in the adjustment mode, the process proceeds to step S5.

  In step S5, the microcomputer 107 determines whether or not the value 1 is set in the adjustment mode flag. As a result, when it is determined that the value 1 is set in the adjustment mode flag, the process proceeds to step S6, where the value 0 is set in the adjustment mode flag and the value 1 is set in the initialization flag, and then the step Proceed to S7.

  On the other hand, if it is determined in step S5 that the value 1 is not set in the adjustment mode flag, the process proceeds to step S7.

  In step S7, the microcomputer 107 determines whether or not a value 0 is set in the initialization flag. As a result, when it is determined that the value 0 is set in the initialization flag, the process proceeds to step S10. On the other hand, if it is determined that the value 0 is not set in the initialization flag, the process proceeds to step S8.

  In step S8, initialization processing for various adjustment values is executed under the control of the microcomputer 107. This initialization process is a process of resetting each offset value constituting various adjustment values to a predetermined specified value (initial value). This specified value is stored in the storage unit 200 in advance.

  That is, the various adjustment values consist of standard values that are adjusted by a worker to correct variation for each set in the factory, and offset values that are adjusted by the user according to user preferences after product shipment. Based on the adjustment value obtained by adding the offset value, the brightness and color of the video are adjusted, and a sound having a predetermined sound volume, a predetermined low sound, and a high sound is output. Next, in step S9, the value 0 is set in the initialization flag.

  Next, in step S10, the microcomputer 107 determines whether or not the value 1 is set in the adjustment mode flag. As a result, when it is determined that the value 1 is set in the adjustment mode flag, the process proceeds to step S12. On the other hand, if it is determined that the value 1 is not set in the adjustment mode flag, the process proceeds to step S11.

  In step S12, the television receiver 100 is driven in the adjustment mode under the control of the microcomputer 107, and the operator can adjust the standard values of various adjustment values and the offset values as necessary.

  In step S11, the television receiver 100 is driven in the normal mode under the control of the microcomputer 107, and the user can watch the television program and adjust the offset values of various adjustment values.

  When the process of step S11 or step S12 ends, this process ends.

  Hereinafter, a specific operation of the present embodiment will be described. First, the operation when the voltage (external voltage) of the electric power supplied to the television receiver 100 via the plug 113 in the factory where the television receiver 100 is adjusted is 150 volts, for example, will be described. To do. In this case, when the television receiver 100 is turned on, in step S1, the microcomputer 107 determines that the external voltage is not 100 volts, and the process proceeds to step S2.

  In step S2, a value 1 is set in the adjustment mode flag, and the process proceeds to step S10. In step S10, it is determined whether or not a value 1 is set in the adjustment mode flag. In this case, since the value 1 is set in the adjustment mode flag, it is determined that the value 1 is set in the adjustment mode flag, and the process proceeds to step S12.

  In step S12, the television receiver 100 is driven in the adjustment mode, and the factory worker can set various adjustment values.

  Next, for example, when the offset values of various adjustment values of the television receiver 100 have not been reset to predetermined predetermined values at the time of factory shipment, the user who purchased the television receiver 100 first supplies power. The operation of the present embodiment when is input will be described.

  Usually, before shipment from the factory, the operator performs a predetermined operation to reset the offset value stored in the second adjustment memory area 202b of the adjustment memory 202 of the storage unit 200 to a predetermined specified value. The worker may forget the resetting work.

  The television receiver 100 is shipped from the factory, and a plug 113 is connected to an outlet at a user's home where the television receiver 100 is purchased, and power of a general household voltage of 100 volts is supplied to the television receiver 100. In step S1, the microcomputer 107 determines that the voltage value (external voltage) of the external power supply is 100 volts, and the process proceeds to step S3.

  In step S3, the microcomputer 107 determines whether or not the adjustment mode has been activated. However, the user rarely performs the adjustment mode activation operation. In this case, there was no activation operation by the user. Therefore, it is determined that the adjustment mode activation operation has not been performed, and the process proceeds to step S5.

  In step S5, it is determined whether or not a value 1 is set in the adjustment mode flag. If a value 1 is set in the adjustment mode flag, a value 0 is set in the adjustment mode flag in step S6. Further, when the value 1 is set in the adjustment mode flag, there is a possibility that the initialization process has not been executed. Therefore, the value 1 is set in the initialization flag so that the initialization process is executed. Proceed to S7.

  On the other hand, if it is determined in step S5 that the value 1 is not set in the adjustment mode flag, the process proceeds to step S7. In step S7, it is determined whether or not a value 0 is set in the initialization flag.

  If the value 1 is set in the initialization flag, the initialization process (reset process) is executed in step S8, the value 0 is set in the initialization flag in step S9, and the process proceeds to step S10. On the other hand, if the initialization flag is set to 0, the process proceeds to step S10.

  In step S10, it is determined whether or not a value 1 is set in the adjustment mode flag. In this case, since the value 0 is set in the adjustment mode flag, the process proceeds to step S11, and normal mode processing is executed. That is, the television receiver 100 selects a channel previously stored as a specified value in the storage unit 200, displays a video of a program broadcast on the channel on the screen of the display unit 105, and displays the video. Is output from the speaker 106.

  At this time, the brightness, hue, and the like of the image displayed on the display unit 105 are the standard values stored in the first adjustment memory area 202a of the adjustment memory 202 of the storage unit 200 and the second adjustment memory area. Each adjustment value is adjusted based on a corresponding one of the adjustment values obtained by adding the offset values stored in 202b. Similarly, the volume of the sound output from the speaker 106, the balance of the low and high sounds, and the like are adjusted based on the corresponding adjustment values.

  As described above, in this embodiment, even when the offset values of various adjustment values of the television receiver 100 are not initialized at the time of factory shipment, the television receiver 100 is purchased. When the user turns on the power, it is recognized that the initialization has not yet been performed, and the initialization process is executed. Therefore, even if a factory worker forgets the initialization process, the initialization process can be surely performed before the user uses it, and the occurrence of complaints after sales is suppressed. Maintenance costs can be reduced.

  In the above embodiment, the case where the offset value of the adjustment value composed of the standard value and the offset value is reset has been described. However, the present invention can also be applied to the case where the adjustment value composed of only the standard value is reset. it can.

  Further, in the above embodiment, the voltage value of the external power supplied from the plug 113 is 100 volts in a general household and 150 volts in a factory, but is limited to these voltage values. is not.

  It should be noted that the configuration and operation of the above-described embodiment are examples, and it is needless to say that they can be changed as appropriate without departing from the spirit of the present invention.

  As an application example of the present invention, for example, the present invention can be applied not only to a television receiver but also to various electronic devices that require an initialization process before shipment.

It is a block diagram which shows the structural example of one Embodiment of the television receiver to which this invention is applied. It is a flowchart for demonstrating operation | movement of embodiment of FIG.
