"program"
The program of one aspect of the present invention has the following steps (see FIG. 22 (A)).

[First step]
In the first step, the settings are initialized (see FIGS. 22A and S1).

For example, predetermined image information to be displayed at startup, a predetermined mode for displaying the image information, and information for specifying a predetermined display method for displaying the image information are acquired from the storage unit 212. Specifically, one still image information or another moving image information can be used for predetermined image information. Moreover, the first mode or the second mode can be used for a predetermined mode. In addition, a first display method, a second display method, or a third display method can be used as a predetermined display method.

[Second step]
In the second step, interrupt processing is permitted (see FIGS. 22 (A) and 22 (S2)). The arithmetic unit for which interrupt processing is permitted can perform interrupt processing in parallel with the main processing. The arithmetic unit that has returned from the interrupt processing to the main processing can reflect the result obtained by the interrupt processing in the main processing.

When the value of the counter is the initial value, the arithmetic unit may perform interrupt processing, and when returning from the interrupt processing, the counter may be set to a value other than the initial value. As a result, interrupt processing can always be performed after the program is started.

[Third step]
In the third step, the image information is displayed using the predetermined mode or the predetermined display method selected in the first step or the interrupt processing (see FIGS. 22 (A) and 22 (S3)). The predetermined mode specifies a mode for displaying information, and the predetermined display method specifies a method for displaying image information. Further, for example, it can be used for information for displaying image information V1, information V11, or information V12.

For example, one method of displaying the image information V1 can be associated with the first mode. Alternatively, another method of displaying the image information V1 can be associated with the second mode. This makes it possible to select a display method based on the selected mode.

For example, three different methods of displaying the image information V1 can be associated with the first display method to the third display method. Thereby, the display can be performed based on the selected display method.

<< First mode >>
Specifically, a method of supplying a selection signal to one scanning line at a frequency of 30 Hz or higher, preferably 60 Hz or higher, and displaying based on the selection signal can be associated with the first mode.

For example, if the selection signal is supplied at a frequency of 30 Hz or higher, preferably 60 Hz or higher, the movement of the moving image can be displayed smoothly.

For example, when the image is updated at a frequency of 30 Hz or higher, preferably 60 Hz or higher, an image that changes so as to smoothly follow the user's operation can be displayed on the information processing device 200 being operated by the user.

《Second mode》
Specifically, the second mode is a method of supplying a selection signal to one scanning line at a frequency of less than 30 Hz, preferably less than 1 Hz, preferably less than once a minute, and displaying based on the selection signal. Can be associated with.

When the selection signal is supplied at a frequency of less than 30 Hz, preferably less than 1 Hz, preferably less than once a minute, a display in which flicker or flicker is suppressed can be obtained. In addition, power consumption can be reduced.

For example, when the information processing device 200 is used for a clock, the display can be updated once a second, once a minute, or the like.

By the way, for example, when a light emitting element is used as a second display element, the light emitting element can be made to emit light in a pulse shape to display image information. Specifically, the organic EL element can be made to emit light in a pulsed manner, and the afterglow can be used for display. Since the organic EL element has excellent frequency characteristics, it may be possible to shorten the time for driving the light emitting element and reduce the power consumption. Alternatively, since heat generation is suppressed, deterioration of the light emitting element may be reduced.

<< First display method >>
Specifically, the method of using the first display element 750 (i, j) for display can be used for the first display method. Thereby, for example, power consumption can be reduced. Alternatively, the image information can be satisfactorily displayed with high contrast in a bright environment.

<< Second display method >>
Specifically, a method of using the second display element 550 (i, j) for display can be used for the second display method. Thereby, for example, the image can be displayed well in a dark environment. Alternatively, a photograph or the like can be displayed with good color reproducibility. Alternatively, a fast-moving moving image can be displayed smoothly.

When the image information V1 is displayed using the second display element 550 (i, j), the brightness for displaying the image information V1 can be determined based on the illuminance information. For example, when the illuminance is 5,000 lux or more and less than 100,000 lux, the image information V1 is displayed by using the second display element 550 (i, j) so that the illuminance is brighter than when the illuminance is less than 5,000 lux.

<< Third display method >>
Specifically, a method using the first display element 750 (i, j) and the second display element 550 (i, j) for display can be used for the third display method. As a result, power consumption can be reduced. Alternatively, the image can be displayed well in a dark environment. Alternatively, a photograph or the like can be displayed with good color reproducibility. Alternatively, a fast-moving moving image can be displayed smoothly. Alternatively, the display can be displayed so that the user feels comfortable.

By the way, a function of adjusting the brightness of a display by using the first display element 750 (i, j) and the second display element 550 (i, j) for display can be called a dimming function. For example, the brightness of a reflective display element can be supplemented by using a display element having a function of emitting light.

Further, a function of using the first display element 750 (i, j) and the second display element 550 (i, j) for display to adjust the color of the display can be referred to as a toning function. For example, the hue of the reflective display element can be changed by using a display element having a function of emitting light. Specifically, the yellowish hue displayed by the reflective liquid crystal element can be brought close to white by using a blue organic EL element. Thereby, for example, character information can be displayed like characters printed on plain paper. Alternatively, the display can be easy on the eyes.

Further, when the first display element 750 (i, j) and the second display element 550 (i, j) are used for display, the color reflected by the object and the color emitted by the object are multiplied. As a result, a pictorial display can be made.

By the way, modern Homo sapiens appeared in the rainforest 160,000 years ago. Therefore, the environment of the rainforest can be called the original environment. The original environment includes various stimuli that have been compromised in modern living environments, such as hypersonics such as high frequency sounds above the audible frequency. And humans have a tendency to feel reassured in the environment in which humans have appeared. As a result, in the modern living environment, human beings feel comfortable when they encounter the stimuli contained in the original environment.

By the way, the user of the display device may be tired of the red, green and blue displays faithfully expressed in the image information. Or you may get tired of the display before you feel tired.

The brightness of the image information V1 displayed by using the second display element 550 (i, j), which is superimposed on the image information V1 displayed by using the first display element 750 (i, j), is determined. , Illuminance information and user preference. As a result, it is possible to display a display that the user feels comfortable with.

[Fourth step]
In the fourth step, if the end command is supplied, the process proceeds to the fifth step, and if the end command is not supplied, the process proceeds to the third step (see FIGS. 22 (A) and 22 (S4)). ).

For example, the end instruction supplied in the interrupt processing may be used for the judgment.

[Fifth step]
The fifth step ends (see FIGS. 22 (A) and 22 (S5)).

《Interrupt processing》
The interrupt processing includes the following sixth to eighth steps (see FIG. 22B).

[Sixth step]
In the sixth step, for example, the detection unit 250 is used to detect the illuminance of the environment in which the information processing device 200 is used (see FIGS. 22B and S6). The color temperature and chromaticity of the ambient light may be detected instead of the illuminance of the environment.

[7th step]
In the seventh step, the display method is determined based on the detected illuminance information. For example, when the illuminance is equal to or more than a predetermined value, the first display method is determined, and when the illuminance is less than the predetermined value, the second display method is determined. Alternatively, when the illuminance is in a predetermined range, the third display method may be used (see FIGS. 22B and S7).

Specifically, when the illuminance is 100,000 lux or more, the first display method is determined, and when the illuminance is less than 5,000 lux, the second display method is determined, and the illuminance is less than 100,000 lux, 5,000 lux. In the above case, the third display method may be determined.

When the color temperature of the ambient light or the chromaticity of the ambient light is detected in the sixth step, the second display element 550 (i, j) is used in the third display method to change the color of the display. You may adjust.

Further, for example, when the first display method is used, the control information SS of the first status is supplied, and when the second display method is used, the control information SS of the second status is supplied, and the third display method is used. When the display method of is used, the control information SS of the third status is supplied.

[8th step]
In the eighth step, interrupt processing is terminated (see FIGS. 22B and S8).

<Configuration example of information processing device 2. ＞
Another configuration of the information processing apparatus according to one aspect of the present invention will be described with reference to FIG.

FIG. 23 is a flowchart illustrating a program of one aspect of the present invention. FIG. 23 is a flowchart illustrating interrupt processing different from the interrupt processing shown in FIG. 22 (B).

Note that the configuration example 3 of the information processing device is different from the interrupt processing described with reference to FIG. 22B in that the interrupt processing includes a step of changing the mode based on a predetermined event supplied. .. Here, the different parts will be described in detail, and the above description will be incorporated for parts where the same configuration can be used.

《Interrupt processing》
The interrupt processing includes the following sixth to eighth steps (see FIG. 23).

[Sixth step]
In the sixth step, if the predetermined event is supplied, the process proceeds to the seventh step, and if the predetermined event is not supplied, the process proceeds to the eighth step (see FIG. 23 (U6)). For example, it can be used as a condition whether or not a predetermined event is supplied in a predetermined period. Specifically, a period of 5 seconds or less, 1 second or less, 0.5 seconds or less, preferably 0.1 seconds or less, and longer than 0 seconds can be set as a predetermined period.

[7th step]
In the seventh step, the mode is changed (see FIG. 23 (U7)). Specifically, when the first mode is selected, the second mode is selected, and when the second mode is selected, the first mode is selected.

[8th step]
In the eighth step, interrupt processing is terminated (see FIG. 23 (U8)). Note that the interrupt processing may be repeatedly executed during the period during which the main processing is being executed.

<< Predetermined event >>
For example, an event such as "click" or "drag" supplied using a pointing device such as a mouse, an event such as "tap", "drag" or "swipe" supplied to the touch panel using a finger or the like as a pointer. Can be used.

Further, for example, the position of the slide bar pointed to by the pointer, the swipe speed, the drag speed, and the like can be used to give the argument of the instruction associated with the predetermined event.

For example, the information detected by the detection unit 250 can be compared with a preset threshold value, and the comparison result can be used for the event.

Specifically, a pressure-sensitive detector or the like in contact with a button or the like arranged so as to be pushed into the housing can be used for the detection unit 250.

<< Instructions associated with a given event >>
For example, an end instruction can be associated with a particular event.

For example, a "page turning command" for switching the display from one displayed image information to another image information can be associated with a predetermined event. It should be noted that an argument for determining the page turning speed or the like used when executing the "page turning command" can be given by using a predetermined event.

For example, a "scroll command" that moves the display position of a part of one image information displayed and displays another part that is continuous with the part can be associated with a predetermined event. It should be noted that an argument for determining the speed of moving the display used when executing the "scroll instruction" can be given by using a predetermined event.

For example, a command for setting a display method or a command for generating image information can be associated with a predetermined event. An argument that determines the brightness of the generated image can be associated with a predetermined event. Further, the argument for determining the brightness of the generated image may be determined based on the brightness of the environment detected by the detection unit 250.

For example, an instruction for acquiring information distributed using a push-type service using the communication unit 290 can be associated with a predetermined event.

It should be noted that the presence or absence of the qualification to acquire the information may be determined by using the position information detected by the detection unit 250. Specifically, if you are inside or in a specific classroom, school, conference room, company, building, etc., you may determine that you are eligible to obtain information. As a result, for example, the information processing apparatus 200 can be used as a textbook or the like by receiving teaching materials distributed in a classroom such as a school or a university (see FIG. 21C). Alternatively, it is possible to receive materials distributed in a conference room of a company or the like and use them as conference materials.

It should be noted that this embodiment can be appropriately combined with other embodiments shown in the present specification.

It should be noted that this embodiment can be appropriately combined with other embodiments shown in the present specification.

For example, in the present specification and the like, when it is explicitly stated that X and Y are connected, the case where X and Y are electrically connected and the case where X and Y function. It is assumed that the case where X and Y are directly connected and the case where X and Y are directly connected are disclosed in the present specification and the like. Therefore, it is not limited to a predetermined connection relationship, for example, a connection relationship shown in a figure or a sentence, and a connection relationship other than the connection relationship shown in the figure or the sentence shall be described in the figure or the sentence.

Here, X and Y are assumed to be objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, etc.).

As an example of the case where X and Y are directly connected, an element (for example, a switch, a transistor, a capacitive element, an inductor, a resistance element, a diode, a display) that enables an electrical connection between X and Y is used. Elements (eg, switches, transistors, capacitive elements, inductors) that allow an electrical connection between X and Y when the element, light emitting element, load, etc. are not connected between X and Y. , A resistance element, a diode, a display element, a light emitting element, a load, etc.), and X and Y are connected to each other.

One or more elements, light emitting elements, loads, etc.) can be connected between X and Y. The switch has a function of controlling on / off. That is, the switch is in a conducting state (on state) or a non-conducting state (off state), and has a function of controlling whether or not a current flows. Alternatively, the switch has a function of selecting and switching the path through which the current flows. The case where X and Y are electrically connected includes the case where X and Y are directly connected.

When X and Y are functionally connected, it includes a case where X and Y are directly connected and a case where X and Y are electrically connected.

It shall be disclosed in documents, etc. That is, when it is explicitly stated that it is electrically connected, the same contents as when it is explicitly stated that it is simply connected are disclosed in the present specification and the like. It is assumed that it has been done.

Note that, for example, the source (or first terminal, etc.) of the transistor is electrically connected to X via (or not) Z1, and the drain (or second terminal, etc.) of the transistor connects Z2. When (or not) electrically connected to Y, or the source of the transistor (or the first terminal, etc.) is directly connected to one part of Z1 and another part of Z1. Is directly connected to X, the drain of the transistor (or the second terminal, etc.) is directly connected to one part of Z2, and another part of Z2 is directly connected to Y. Then, it can be expressed as follows.

For example, "X and Y, the source (or the first terminal, etc.) and the drain (or the second terminal, etc.) of the transistor are electrically connected to each other, and the X, the source of the transistor (or the first terminal, etc.) (Terminals, etc.), transistor drains (or second terminals, etc.), and Y are electrically connected in this order. " Alternatively, "the source of the transistor (or the first terminal, etc.) is electrically connected to X, the drain of the transistor (or the second terminal, etc.) is electrically connected to Y, and the X, the source of the transistor (such as the second terminal). Or the first terminal, etc.), the drain of the transistor (or the second terminal, etc.), and Y are electrically connected in this order.

(Terminals, etc.), transistor drains (or second terminals, etc.), and Y are provided in this connection order. " By defining the order of connections in the circuit configuration using the same representation method as these examples, the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor can be separated. Separately, the technical scope can be determined.

Alternatively, as another expression, for example, "the source of the transistor (or the first terminal, etc.) is electrically connected to X via at least the first connection path, and the first connection path is. It does not have a second connection path, and the second connection path is between the source of the transistor (or the first terminal, etc.) and the drain of the transistor (or the second terminal, etc.) via the transistor.

It is connected, and the third connection path does not have the second connection path, and the third connection path is a path via Z2. " Alternatively, "the source of the transistor (or the first terminal, etc.) is electrically connected to X via Z1 by at least the first connection path, and the first connection path is the second connection path. The second connection path has a connection path via a transistor, and the drain (or the second terminal, etc.) of the transistor has a connection path via Z2 by at least a third connection path. , Y is electrically connected, and the third connection path does not have the second connection path. " Alternatively, "the source of the transistor (or the first terminal, etc.) is electrically connected to X via Z1 by at least the first electrical path, the first electrical path being the second. It does not have an electrical path, and the second electrical path is an electrical path from the source of the transistor (or the first terminal, etc.) to the drain of the transistor (or the second terminal, etc.). The drain (or second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least a third electrical path, the third electrical path being a fourth electrical path. The fourth electrical path is an electrical path from the drain of the transistor (or the second terminal, etc.) to the source of the transistor (or the first terminal, etc.). " can do. By defining the connection path in the circuit configuration using the same representation method as these examples, the source (or first terminal, etc.) of the transistor and the drain (or second terminal, etc.) can be distinguished. , The technical scope can be determined.

Note that these expression methods are examples, and are not limited to these expression methods. Here, it is assumed that X, Y, Z1 and Z2 are objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, etc.).

Even if the circuit diagram shows that the independent components are electrically connected to each other, one component has the functions of a plurality of components. There is also. For example, when a part of the wiring also functions as an electrode, one conductive film has the functions of both the wiring function and the electrode function. Therefore, the term "electrically connected" as used herein includes the case where one conductive film has the functions of a plurality of components in combination.
