Description

  The present invention relates to an information processing apparatus equipped with an electronic level function.

  Some information processing apparatuses having an imaging function such as a digital camera, a smartphone, and a tablet terminal include an acceleration sensor. By using the acceleration sensor, for example, the function of an electronic level indicating the inclination of the information processing apparatus can be realized. Further, it is possible to realize an impact detection function when the information processing apparatus falls. These functions are enabled by the gravitational acceleration detected by the acceleration sensor. However, the optimum sampling period of gravity acceleration is different for each function.

  For example, when the sampling period is short, the time response of the electronic level becomes faster. In this case, even if the user holds the information processing apparatus (imaging apparatus) fixed, the display of the electronic level may change rapidly. For this reason, an electronic level that originally assists the user in photographing is obstructing the user's photographing. When the sampling period is long, it is difficult to accurately detect the impact because the impact is instantaneous.

  The imaging device of Patent Document 1 switches between “electronic level mode” and “impact detection mode” according to the amount of change in gravitational acceleration. The imaging apparatus performs a gravity acceleration smoothing process in the electronic level mode, and does not perform a smoothing process in the impact detection mode. Thereby, even if the sampling period of gravitational acceleration is constant, in the electronic level mode, the number of sampling can be reduced by smoothing, and the change in display of the electronic level can be reduced. In the impact detection mode, it is possible to detect an impact at the moment of dropping.

  However, when shooting in the electronic level mode, the time response of the electronic level may not be appropriate depending on the shooting status. For example, when it is necessary to move the information processing apparatus quickly, such as in a sports scene or baby shooting, the follow-up of the display of the electronic level may not be sufficient.

  In order to solve the above problems, it is a main object of the present invention to provide an information processing apparatus that controls time responsiveness of an electronic level based on information relating to shooting such as a shooting scene.

  An information processing apparatus according to the present invention that solves the above-described problems includes an imaging unit that performs imaging, imaging information acquisition unit that acquires information regarding imaging by the imaging unit, and a time response of an electronic level based on the information regarding imaging A time responsiveness determining means for determining a property, an arithmetic processing determining means for determining a processing condition for displaying the electronic level based on the time responsiveness, and based on the determined condition, Arithmetic means for performing arithmetic processing; and display control means for generating an image of the electronic level based on a calculation result and displaying the generated image on a predetermined output means based on the time response. It is characterized by that.

  According to the present invention, by determining the time responsiveness of the electronic level based on information related to shooting, it is possible to display an electronic level that is optimal for the shooting situation of the user.

[First Embodiment]
FIG. 1 is a hardware configuration diagram of the information processing apparatus according to the present embodiment. The information processing apparatus 100 is configured by connecting a CPU 102, a ROM 103, a RAM 104, an input interface (I / F) 105, an output I / F 106, and an input / output I / F 107 to a bus 101. An input device 109, an output device 110, a storage device 108, and an imaging device 111 are connected to the information processing apparatus 100. In the present embodiment, the information processing device 100, the input device 109, the output device 110, the storage device 108, and the imaging device 111 are integrally configured. The information processing apparatus 100 is an apparatus having an imaging function such as a digital camera, a smartphone, or a tablet terminal.

The bus 101 includes an address bus, a data bus, a control bus, and the like. Each component of the information processing apparatus 100 performs communication via the bus 101. A CPU (Central Processing Unit) 102 reads a computer program and RAM (Random Access).
Memory) 104 is used as a work area. The computer program is, for example, a drive program stored in a ROM (Read Only Memory) 103 and an application program stored in at least one of the ROM 103 and a storage device 108 described later.
The CPU 102 performs various processes by the information processing apparatus 100 by executing a computer program.

  The input interface (I / F) 105 receives various data, signals, commands, and the like input from the input device 109 and transmits them to the CPU 102. The input device 109 includes various sensors, input buttons, setting buttons, a touch panel, and the like. Examples of the sensor include an acceleration sensor, a gyro sensor, a geomagnetic sensor, a GPS (Global Positioning System) sensor, an infrared sensor, an optical sensor, and an ultrasonic sensor. The sensor detects the state of the information processing apparatus 100 (imaging apparatus 111). The input button and the setting button are operated (for example, pressed) by the user of the information processing apparatus 100 and input commands and data assigned to each button. Examples of the input button and setting button include a shutter button for instructing start of shooting, a shooting mode setting button, and the like.

  The output I / F 106 outputs execution results of various processes to the output device 110 under the control of the CPU 102. The output device 110 is a display device, for example. For example, the output I / F 106 causes the output device 110 to display an image of an electronic level under the control of the CPU 102.

  The input / output I / F 107 is connected to the storage device 108 and the imaging device 111. The storage device 108 is a mass storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The storage device 108 stores computer programs executed by the CPU 102 and various data written by the CPU 102 via the input / output I / F 107. The imaging device 111 includes a lens and an imaging element. The imaging device 111 captures an image according to an instruction from the CPU 102 via the input / output I / F 107 and transmits the captured image to the CPU 102.

  FIG. 2 is a functional block diagram of the information processing apparatus 100. Each function is realized by the CPU 102 reading and executing a computer program from at least one of the ROM 103 and the storage device 108. In the present embodiment, each function is realized by software, but at least a part may be realized by hardware. The information processing apparatus 100 functions as a photographing information acquisition unit 201, a time responsiveness determination unit 202, a calculation processing determination unit 203, a calculation unit 204, and a display control unit 205.

  The imaging information acquisition unit 201 is realized by the input I / F 105 and the CPU 102. The imaging information acquisition unit 201 acquires information related to imaging from the input device 109 and transmits the information to the time responsiveness determination unit 202. The imaging information acquisition unit 201 acquires, for example, triaxial gravity acceleration output from the acceleration sensor as information related to imaging, and transmits the information to the time responsiveness determination unit 202. The acceleration sensor detects triaxial gravity acceleration. In the present embodiment, the measurement range of the acceleration sensor is set to 3.0 G or less, and the imaging information acquisition unit 201 acquires a signal indicating triaxial gravity acceleration from the acceleration sensor at intervals of 10 milliseconds. Further, the shooting information acquisition unit 201 acquires the shooting mode of the imaging device 111 set by the setting button as information related to shooting, and transmits the information to the time responsiveness determination unit 202. The shooting modes are, for example, “fully automatic mode”, “kids mode”, “sport mode”, “landscape mode”, “starry sky mode”, and the like. The imaging information acquisition unit 201 acquires an instruction to display an electronic level. The imaging information acquisition unit 201 acquires an image captured by the imaging device 111 and transmits the acquired image to the time responsiveness determination unit 202.

  The time responsiveness determination unit 202 is realized by the CPU 102. The time responsiveness determination unit 202 determines the time responsiveness of the electronic level based on information related to imaging acquired from the imaging information acquisition unit 201. The time responsiveness determining unit 202 transmits the time responsiveness result to the arithmetic processing determining unit 203 and the display control unit 205. FIG. 3 is a view showing an example of a table representing the relationship between information related to photographing and time responsiveness. Each table of FIGS. 3A and 3B is held in the RAM 104, for example. In FIG. 3, the time responsiveness is set in three stages of “fast”, “normal”, and “slow”. For example, “very fast”, “fast”, “normal”, “slow” , “Very slow” or the like may be set in five stages.

  FIG. 3A is a table showing the relationship between the shooting mode of the imaging device 111 and time response. The time responsiveness determination unit 202 determines the time responsiveness corresponding to the shooting mode acquired from the shooting information acquisition unit 201 with reference to the table of FIG. For example, the time responsiveness determination unit 202 sets the time responsiveness to “normal” when the shooting mode is “fully automatic mode”. The time responsiveness determination unit 202 sets the time responsiveness to “fast” when the shooting mode is “kids mode” or “sports mode”. This is because it is determined that the amount of movement of the information processing apparatus 100 increases because the movement of the subject that is the object to be photographed is fast and large, and the followability of the display of the electronic level is increased. The time responsiveness determination unit 202 sets the time responsiveness to “slow” in the “landscape mode” or the “starry sky mode”. This is because it is determined that the movement of the information processing apparatus 100 is slow, and the display of the electronic level is changed rapidly. These are merely examples, and the time responsiveness of the electronic level is set for each shooting mode that can be set by the information processing apparatus 100.

  Further, the time responsiveness determination unit 202 determines the time responsiveness of the electronic level based on the change amount of the triaxial gravity acceleration acquired from the imaging information acquisition unit 201. FIG. 3B is a table showing the relationship between the amount of change in the state of the information processing apparatus 100 and time responsiveness. The time responsiveness determination unit 202 calculates the amount of change in the state of the information processing apparatus 100 based on the gravitational acceleration acquired from the imaging information acquisition unit 201. The time responsiveness determination unit 202 determines the time responsiveness corresponding to the calculated amount of change in the state of the information processing apparatus 100 with reference to the table of FIG. For example, when the amount of change in the state of the information processing apparatus 100 is 0.3 G or more, the time responsiveness determination unit 202 sets the time responsiveness to “fast” and the amount of change is 0.1 G or less. Set the time response to “slow”. When the amount of change in the state of the information processing apparatus 100 is other than that, the time responsiveness determination unit 202 maintains the time responsiveness set at that time. Note that this is an example, and the present invention is not limited to this.

  Further, the time responsiveness determination unit 202 may determine the time responsiveness of the electronic level based on the captured image acquired from the imaging information acquisition unit 201. The time responsiveness determination unit 202 continuously acquires, for example, images taken by the imaging device 111, calculates the movement amount of at least one of the subject and the background included in the image, and the time responsiveness according to the movement amount. To decide. The time responsiveness determination unit 202 compares two images acquired at a predetermined time interval, for example, and calculates a movement amount of at least one of the subject and the background in the image. For example, the time responsiveness determination unit 202 sets the time responsiveness to “fast” when the moving amount of the subject is 100 dots or more, and sets the time responsiveness to “slow” when the moving amount is 10 dots or less. . That is, the time responsiveness is set earlier as the amount of movement of the subject increases. The same applies to the case of using the background movement amount.

  The arithmetic processing determining unit 203 is realized by the CPU 102. The arithmetic processing determination unit 203 is based on the time responsiveness of the electronic level obtained from the time responsiveness determination unit 202, and performs an arithmetic processing for displaying the electronic level (calculation interval) and smoothes during the arithmetic processing. Arithmetic processing conditions such as chemical number are determined. The arithmetic processing determination unit 203 transmits the determined arithmetic processing conditions to the arithmetic unit 204. The arithmetic processing for displaying the electronic level is, for example, calculation processing of the tilt angle of the information processing apparatus 100 using gravitational acceleration.

  FIG. 4A is an exemplary diagram of a table representing the relationship between time responsiveness and calculation processing conditions. The table shown in FIG. 4A is held in the RAM 104, for example. The shorter the calculation interval, the faster the time response of the electronic level. For example, as shown in FIG. 4A, the calculation interval is 10 milliseconds when the time responsiveness is “fast”, 20 milliseconds when “normal”, and 30 when “slow”. Milliseconds. The greater the smoothing number, the slower the time response of the electronic level. For example, as shown in FIG. 4A, the smoothing number is 4 when the time response is “fast”, 8 when “normal”, and 16 when “slow”. It is. Although not shown in FIG. 4A, the gravitational acceleration may be weighted as a calculation processing condition. The information processing apparatus 100 calculates the tilt angle of the information processing apparatus 100 by increasing the weight of the gravitational acceleration acquired most recently as the time response is faster.

The calculation unit 204 is realized by the CPU 102. The calculation unit 204 calculates the tilt angle of the information processing apparatus 100 based on the calculation processing condition acquired from the calculation processing determination unit 203 and transmits the calculation result to the display control unit 205. The inclination angles of the information processing apparatus 100 are, for example, “horizontal angle” and “tilting angle”.
The “horizontal angle” and “tilting angle” are calculated from gravitational acceleration in the X-axis direction and the Y-axis direction detected by the acceleration sensor. Specifically, the horizontal angle is represented by the arc tangent of the quotient obtained by dividing the value of gravitational acceleration in the X-axis direction by the value in the Y-axis direction. The tilt angle is represented by the arc tangent of the quotient obtained by dividing the value of the gravitational acceleration in the Y-axis direction by the value in the Z-axis direction.
(Horizontal angle)
= Arctan (gravity acceleration in the X-axis direction / gravity acceleration in the Y-axis direction)
(Tilting angle)
= Arctan (Y-axis gravity acceleration / Z-axis gravity acceleration)

The display control unit 205 is realized by the CPU 102 and the output I / F 106. The display control unit 205 refers to the table representing the relationship between the time responsiveness and the update interval in FIG. 4B according to the time responsiveness acquired from the time responsiveness determining unit 202, and displays the image of the electronic level. Determine the update interval. The display control unit 205 causes the output device 110 to display an image of the electronic level at the determined update interval. The display control unit 205 sets the update interval to 200 milliseconds when the time responsiveness is “early”, the update interval to 300 milliseconds when “normal”, and the update interval to 400 when “slow”. Decide on milliseconds.
The display control unit 205 generates an image of the electronic level based on the “horizontal angle” and “tilting angle” that are the calculation results acquired from the calculation unit 204, and outputs the generated image at the determined update interval. It is displayed on the device 110.

  FIG. 5A and FIG. 5B are flowcharts showing an electronic level display process by the information processing apparatus 100 as described above.

  The imaging information acquisition unit 201 acquires information (imaging information) related to imaging including the imaging mode of the imaging device 111, the display command of the electronic level, and the triaxial gravity acceleration from the input device 109 (S301). The shooting information acquisition unit 201 stores the acquired shooting information in the RAM 104. In the present embodiment, the acquired shooting mode is referred to as a “fully automatic mode”.

  The time responsiveness determination unit 202 determines the time responsiveness of the electronic level with reference to the respective tables in FIG. 3 based on the photographing mode and the amount of change in gravitational acceleration (S302). Details of the time responsiveness determination process will be described with reference to FIG.

  The time responsiveness determining unit 202 determines the time responsiveness with reference to FIG. 3A according to the shooting mode stored in the RAM 104 (S3021). In the present embodiment, since the shooting mode is the “fully automatic mode”, the time response is “normal”.

  The time responsiveness determination unit 202 identifies the amount of change in the state of the information processing apparatus 100 from the combined value of the triaxial gravitational accelerations stored in the RAM 104 (S3022). The time responsiveness determination unit 202 calculates a composite value of each of the two triaxial gravity accelerations acquired at different timings stored in the RAM 104, for example, and calculates the difference between these composite values in the state of the information processing apparatus 100. Change amount. In the present embodiment, the amount of change in the state of the information processing apparatus 100 is “0.05 G”.

The time responsiveness determining unit 202 uses the specified amount of change in the state of the information processing apparatus 100 as a predetermined value (in this case, 0.3 G, 0.1 G) that is a criterion for determining the time responsiveness in the table of FIG. To determine the time response of the electronic level. First, the time responsiveness determination unit 202 determines whether or not the amount of change is greater than 0.3 G (S3023). When the amount of change is larger than 0.3 G (S3023: Y), the time responsiveness determining unit 202 determines the time responsiveness of the electronic level as “early” (S3024).
When the amount of change is 0.3 G or less (S3023: N), the time responsiveness determination unit 202 determines whether or not the amount of change is smaller than 0.1 G (S3025). When the amount of change is smaller than 0.1 G (S3025: Y), the time responsiveness determination unit 202 determines the time responsiveness of the electronic level as “slow” (S3026). When the amount of change is 0.1 G or more (S3025: N), the time responsiveness determining unit 202 maintains the time responsiveness of the electronic level determined in S3021.

  Through the above processing, the time responsiveness determination unit 202 determines the time responsiveness of the electronic level. The arithmetic processing determining unit 203 determines arithmetic processing conditions with reference to FIG. 4A according to the time response of the electronic level (S303). In the present embodiment, since the time responsiveness is “slow”, the arithmetic processing determination unit 203 determines the arithmetic processing condition where the calculation interval is “30 milliseconds” and the smoothing number is “16”.

  The calculation unit 204 calculates the horizontal angle and the tilt angle of the information processing apparatus 100 using the triaxial gravity acceleration stored in the RAM 104 based on the calculation processing condition determined by the calculation processing determination unit 203 (S304). . The display control unit 205 sets the display update interval of the electronic level according to the time responsiveness stored in the RAM 104 (S305). In this embodiment, since the time responsiveness is “slow”, the display control unit 205 sets the update interval of the electronic level to “400 milliseconds” with reference to FIG. The display control unit 205 generates an image of the electronic level based on the horizontal angle and the tilt angle calculated in S304, and displays the image of the electronic level on the output device 110 at the update interval set in S305 (S306). . The information processing apparatus 100 performs the above processing at a time interval for acquiring the gravitational acceleration from the acceleration sensor, for example, at an interval of 10 milliseconds.

In the information processing apparatus 100 of the present embodiment, the change amount of the state of the information processing apparatus 100 is specified by the acceleration sensor, but may be specified from other information. For example, the amount of change in the state of the information processing apparatus 100 may be specified based on the detection result by a gyro sensor, a geomagnetic sensor, a GPS sensor, or the like. The amount of change in the state of the information processing apparatus 100 may be specified by combining the detection results of these sensors.
In the present embodiment, since the information processing apparatus 100 and the imaging apparatus 111 are integrally configured, the amount of change in the state of the information processing apparatus 100 is specified, but if these are separate, the imaging apparatus The amount of change in state 111 is specified. In this case, sensors are provided in the imaging apparatus 111, and the information processing apparatus 100 acquires the detection result of the sensor from the imaging apparatus 111, calculates the amount of change in the state of the imaging apparatus 111, and performs the above processing.

The time responsiveness of the electronic level may be slow, for example, when the shooting mode is zoom-in shooting, and may be quick when zoom-out shooting is performed. At the time of zoom-in shooting, since the subject is imaged large and the amount of change in the state of the imaging device 111 becomes large, it is necessary to improve the followability of the display of the electronic level. For this reason, the information processing apparatus 100 slows time response. Conversely, during zoom-out shooting, the amount of change in the state of the imaging device 111 is small, so it is necessary to increase the display stability of the electronic level. For this reason, the information processing device 100 increases the time response. .
The information processing apparatus 100 may determine that the time when the shutter button is half-pressed is the state immediately before photographing, and delay the display responsiveness of the electronic level. In this case, the time response of the electronic level may be delayed in steps according to the time during which the shutter button is half-pressed. The information processing apparatus 100 may determine the time responsiveness of the electronic level only in the shooting mode. In this case, the processing of S3022 to S3026 in FIG.

  The information processing apparatus 100 as described above specifies the amount of change in the state of the information processing apparatus 100 (imaging device 111), the amount of movement of the subject, and the like when displaying the image of the electronic level, and the time of the electronic level. Determine responsiveness. Therefore, the electronic level can be displayed with an optimal time response in accordance with the shooting situation. This improves the convenience of the user's electronic level.

[Second Embodiment]
The responsiveness of the electronic level may be determined separately for the horizontal angle and the tilt angle. The hardware configuration (see FIG. 1) and functional blocks (see FIG. 2) of the information processing apparatus 100 according to the second embodiment for that purpose are the same as those in the first embodiment, and a description thereof is omitted.

  Also in the second embodiment, the electronic level display process by the information processing apparatus 100 is the same process as in the first embodiment (see FIG. 5A), but the time responsiveness determination process is different. In the second embodiment, the information processing apparatus 100 acquires panorama mode setting information in S301 as a shooting mode. FIG. 6 is a flowchart showing the time responsiveness determination process (S302 in FIG. 5A) according to the second embodiment.

  The time responsiveness determination unit 202 determines the time responsiveness of the electronic level based on the panorama mode setting information with reference to the table shown in FIG. 7 (S401). FIG. 7 is an example of a table showing the relationship between panorama mode setting and time responsiveness. The table in FIG. 7 is held in the RAM 104, for example. The time responsiveness determination unit 202 determines the time responsiveness of each of the “horizontal angle” and the “tilting angle” according to the set panorama mode. In the present embodiment, it is assumed that the horizontal panorama mode is set. In this case, the time responsiveness determination unit 202 determines the time responsiveness of the electronic level of “horizontal angle” as “fast” and the “tilt angle” as “slow”.

  The time responsiveness determination unit 202 identifies the amount of change in the gravitational acceleration in the X-axis direction and the Y-axis direction of the information processing apparatus 100 (imaging device 111) from the triaxial gravitational acceleration stored in the RAM 104 (S402). ). For example, the time responsiveness determination unit 202 calculates the difference between the gravitational accelerations in the X-axis direction and the Y-axis direction of the two triaxial gravitational accelerations acquired at different timings stored in the RAM 104, for example. It is calculated as the amount of change in gravitational acceleration in the axial direction and the Y-axis direction. In this embodiment, the amount of change in gravitational acceleration in the X-axis direction is “0.2 G”, and the amount of change in gravitational acceleration in the Y-axis direction is “0.1 G”.

  The time responsiveness determination unit 202 compares the amount of change in gravitational acceleration in the X-axis direction and the amount of change in gravitational acceleration in the Y-axis direction to determine which value is larger (S403). When the amount of change in the gravitational acceleration in the X-axis direction is larger (S403: Y), the time responsiveness determining unit 202 determines the time responsiveness of the horizontal electronic level to be “early”, and the angle angle electronic The time response of the level is determined as “slow”. When the amount of change in the gravitational acceleration in the Y-axis direction is larger (S403: N), the time responsiveness determining unit 202 determines that the time responsiveness of the horizontal electronic level is "slow" The time responsiveness of the level is determined to be “fast”.

  When the time responsiveness of the electronic level is determined, the information processing apparatus 100 continues the processing from S303 onward in FIG. 5A and displays an image of the electronic level on the output device 110. In this embodiment, since the amount of change in gravitational acceleration in the X-axis direction is 0.2 G and the amount of change in gravitational acceleration in the Y-axis direction is 0.1 G, the display time response of the horizontal electronic level is “fast”. "The time response of the tilt angle electronic level is determined to be" slow ". When the amount of change in gravitational acceleration in the X-axis direction is equal to the amount of change in gravitational acceleration in the Y-axis direction, the time responsiveness determined in S401 is used as it is. Note that the information processing apparatus 100 may determine the time responsiveness of the electronic level only in the shooting mode (panoramic mode). In this case, the processes of S402 to S405 in FIG. 6 are omitted.

  The information processing apparatus 100 according to the second embodiment can accelerate the time responsiveness of an axis having a high priority for the user and can delay the time responsiveness of an axis having a low priority. Therefore, the operability of the electronic level is improved.

[Third Embodiment]
In the third embodiment, the display form of the electronic level is determined based on the time response of the electronic level. The hardware configuration (see FIG. 1) of the information processing apparatus 100 of the third embodiment for that purpose is the same as that of the first embodiment, and the description thereof is omitted.

  FIG. 8 is a functional block diagram of the information processing apparatus 100 according to the third embodiment. Each function is realized by the CPU 102 reading and executing a computer program from at least one of the ROM 103 and the storage device 108. In the present embodiment, each function is realized by software, but at least a part may be realized by hardware. The information processing apparatus 100 according to the third embodiment has a configuration in which a display form determination unit 501 is added to the functional blocks (see FIG. 2) according to the first embodiment. Description of other similar configurations is omitted.

  The display form determination unit 501 determines the display form of the image of the electronic level according to the time responsiveness determined by the time responsiveness determination unit 202. FIG. 9 is an exemplary diagram of a table representing the relationship between time responsiveness and display form. The table of FIG. 9 is held in the RAM 104, for example.

  The display form determination unit 501 determines the color of the image of the electronic level according to, for example, time response. In the example of FIG. 9, the display form determination unit 501 displays the image of the electronic level as “red” when the time response of the electronic level is “fast”, “orange” when “normal”, and “slow”. In this case, “blue” is determined. Moreover, the display form determination part 501 determines the shape of the image of an electronic level according to time responsiveness, for example. In the example of FIG. 9, the display form determination unit 501 displays an image of the electronic level as “diamond” when the time response of the electronic level is “fast”, “ellipse” when “normal”, “ When it is “slow”, it is determined to be “circular”. Moreover, the display form determination part 501 determines the resolution of the angle of an electronic level according to time response, for example. In the example of FIG. 9, the display form determination unit 501 sets the resolution to “0.5 degrees” when the time response of the electronic level is “fast”, “1 degree” when “normal”, and “slow”. ”Is determined to be“ twice ”and the electronic level is displayed. The display form of the image of the electronic level may be determined by combining these. The display form determination unit 501 determines at least one of these as an electronic level image display form.

  FIG. 10 is a flowchart showing display processing of the electronic level by the information processing apparatus 100. The same step number is attached to the process similar to the display process of the electronic level of the first embodiment. Description of similar processing is omitted.

  When the display control unit 205 sets the display update interval of the electronic level (S305), the display form determination unit 501 refers to the table of FIG. 9 and determines the electronic level according to the time responsiveness stored in the RAM 104. The display form of the image of the container is determined (S601). In this embodiment, since “slow” is set in the time response, the display form determination unit 501 sets the color of the electronic level image to “blue”, the shape to “diamond”, and the resolution to “2 degrees”.
