Abstract

PURPOSE:To automatically store an operation condition which a user desires without changing the stored contents of a preset switch by a user with respect to a method where the operation parameter preset in an electronic equipment such as an electronic tuner, an electronic graphic equalizer, or an acoustic field controller is automatically stored. CONSTITUTION:When a parameter Pa is kept set for a fixed time or longer, it is stored as the preset value (column (a)). At the time of storage, another parameter having the lowest priority level is substituted to store the preset value, and the highest priority level is given to this value, and the priority levels of the other parameters are reduced one by one (column (b)). When the parameter Pb to be stored is equal to an already stored parameter P2 (column (c)), only priority levels are rewritten (column (d)).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically storing preset operating parameters in electronic devices such as electronic tuners, electronic graphic equalizers, and sound field control devices having a preset function.

0002

[Prior Art] Electronic devices such as electronic tuners, electronic graphic equalizers, and sound field control devices are usually equipped with a plurality of preset switches, and by pressing any of these switches, memory corresponding to the individual preset switch is stored. It has a preset function where the operating parameters are set. For example, in an electronic tuner, transmission frequencies of broadcast stations are stored in correspondence with individual preset switches, and a user can tune to a desired broadcast station by selecting one of the preset switches. In electronic graphic equalizers, equalizer characteristics are stored in correspondence with individual preset switches, and a user can select a desired equalizer characteristic by operating the preset switches. Further, in the sound field control device, the reverberation time and reverberant sound level given to the sound source are stored in correspondence with each preset switch, and can be selected by operating the preset switch.

0003

[Problems to be Solved by the Invention] As described above, the preset function is a convenient function that can replace complicated operations with simple switch operations. When trying to use the device under certain conditions, there is a problem in that each time it is necessary to directly change the value of the operating parameter without using the preset switch, or to change the stored operating parameter. .

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an automatic presetting method that automatically stores operating conditions preferred by the user without the user having to perform an operation to change the stored contents of a preset switch.

[0005]

[Means for Solving the Problems] The automatic presetting method for an electronic device of the present invention, which achieves the above objects, provides: i) for one or more user-settable operating parameters, the values of the operating parameters set by the user are set; ii) when the same value is held for a predetermined period of time or more, the value or set of values of the operating parameter is stored as a preset value, and iii)
iv) When the number of stored preset values exceeds a predetermined number, the oldest preset value is deleted; and iv) When the user operates a preset switch, each step of setting one of the stored preset values as an operating parameter is performed. It is characterized by comprising:

[0006]

[Operation] When the same operating parameter value is maintained for a predetermined period of time or longer, this operating condition is considered to be one of the conditions preferred by the user. Therefore, by automatically storing this operating condition as a preset value each time, the operating condition preferred by the user is automatically preset.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which the present invention is applied to a preset function of an electronic tuner will be described. FIG. 1 is a schematic block diagram of an electronic tuner. The tuner 10 includes a tuning circuit, a detection circuit, an amplification circuit, etc., and tunes to, detects, and amplifies radio waves of a desired frequency, and outputs an audio signal. The microcomputer 12 is equipped with a CPU, ROM, RAM, and an input/output interface, and provides a frequency division ratio to a PLL synthesizer that creates a local oscillation signal in the tuner 10 in accordance with commands given by the user via the key matrix 14. , controls the receiving frequency of the tuner 10. The display 16 displays operating conditions such as reception frequency.

The keys in the key matrix include six preset keys, and R in the microcomputer 12.
AM stores data indicating reception frequencies corresponding to each of the six preset keys. When one of the preset keys is pressed, the corresponding frequency division ratio is applied to the tuner 10, and the tuner 10 tunes to the desired frequency. FIG. 2 is a diagram for explaining one embodiment of the present invention. As shown in column (a), the six keys currently have reception frequencies P1, P4, P2, P5, P6, P3 in the order of key arrangement.
are stored, and their priorities (input order) are 1, 4, 2, 5, 6, and 3, respectively. Assume that the tuning button is operated to tune to a frequency Pa different from P1 to P6, and this continues for a certain period of time.

When the time that frequency Pa is maintained exceeds a predetermined value, it is determined that this is the frequency of the station preferred by the user, and P6, which has the lowest priority, is replaced, its priority is set to 1, which is the highest, and the other 5 Increase the priority of each item by 1 (column (b)). It is assumed that the frequency is then tuned to Pb, which has the same frequency as P2, by operating the preset key or the tuning button and held for a predetermined time or more (column (c)). At this time, only the process of changing the priority is performed. In other words, P2 has a priority of 1, and P1 and P, which have a higher priority than P2,
Increase the priority of a by 1 (column (d)).

FIG. 3 is a flowchart showing the processing in the microcomputer 12 for realizing the process explained in FIG. When an operation to change the frequency is performed (step a), the time T at that time is substituted for the operation time T0 (step b), and other necessary processing is performed (step e). When there is no change in the frequency, the difference between the current time T and the operation time T0, that is, the elapsed time since the frequency change operation is performed, is determined, and the magnitude of the predetermined constant is determined (
Step c), if the value is not greater than a predetermined constant, the flow goes to step e; if the value is greater than the predetermined constant, the storage process (
(described later), and then proceed to step e.

FIG. 4 is a flowchart showing the storage process. First, it is determined whether or not there is one that is equal to the frequency value to be stored among the six already stored frequency values (step a), and if there is an equal one, the priority order as described above is determined. Make only changes (step b)
. If there is no equal value, the frequency value with the lowest priority is replaced with the frequency value to be stored (step c), and the priority order is changed (step d).

[0012] The above description has been made regarding the case of an electronic tuner, but it goes without saying that the present invention can also be applied to an electronic graphic equalizer and a sound field control device. However, in the case of an electronic graphic equalizer, it is a combination of multiple parameters, such as the level of each frequency, and in the case of a sound field control device, the reverberation time and the reverberant sound level. , it will be determined whether all parameters match.

FIG. 5 is a diagram showing a second embodiment of the present invention. In this embodiment, the values of the stored parameters are compared and arranged in order of magnitude to facilitate operation of the preset keys. Preferably, preset keys are assigned in order of frequency in the case of an electronic tuner, and in order of reverberation time in the case of a sound field control device.

As shown in column (a), each parameter is arranged in order of size (P1 > P4 > P2 > P5 > P6 >
P3). When storing Pa that is different from any of P1 to P6, first, P with the lowest priority is stored.
6 is replaced by Pa, its priority becomes 1, and the others are incremented by 1 (column (b)). Next, if Pa has a size between P1 and P4, then Pa
Relocation is performed so that it is between 1 and P4 ((
c) column).

FIG. 6 is a partially modified flowchart of the storage process shown in FIG. 4 in order to realize the embodiment described in FIG. In FIG. 6, after the priority changing process of step d, a process of rearranging parameters in order of size (step e) is added. In the embodiment described above, as many preset keys as there are stored parameters or parameter sets are provided, and the parameters corresponding to the pressed preset keys are set in the electronic device. , the parameters may be set in the sequence shown in FIG. 2 or 5 each time the button is pressed.

[0016]

As described above, according to the present invention, an automatic presetting method is provided in which preset parameters are automatically stored without the user performing any storage operation.
