  The image feature amount includes, for example, at least one of an image color feature amount, a shape feature amount, a pattern feature amount, and a texture feature amount. Note that the feature amount of an image is not limited to a physically measurable physical feature amount, and a Kansei feature amount indicating an impression received by a person from an image is obtained by a statistical method, and the Kansei feature amount is obtained from an image. It is good also as feature-value of.

  The feature amount axis display control unit 40 of the display control unit 22 of this example can switch whether or not to display the feature amount axis. In a state where the feature amount axis is displayed on the screen of the display panel 12 by the feature amount axis display control unit 40 of the display control unit 22 (hereinafter referred to as “feature amount axis display state”), the image display control unit 42 of the display control unit 22. Displays a plurality of images superimposed on the displayed feature amount axis on the screen of the display panel 12. In a state where the feature amount axis is not displayed on the screen of the display panel 12 by the feature amount axis display control unit 40 of the display control unit 22 (hereinafter referred to as “feature amount axis non-display state”), the image display control unit of the display control unit 22 42 displays a plurality of images along the non-display feature amount axis on the screen of the display panel 12.

  As shown in FIG. 2, the touch operation analysis unit 18 of the present example has two points when two points are touched on the screen of the display panel 12 based on the touch position acquired by the touch position acquisition unit 16. A two-point touch operation detection unit 50 that detects the touch operation. The two-point touch operation detection unit 50 of this example includes a linear inclination detection unit 52 that detects an inclination of a straight line connecting two touched points on the screen of the display panel 12 (hereinafter referred to as “a straight line between two points”); A distance between straight lines detection unit 54 for detecting a distance between a straight line between two points touched on the screen of the display panel 12 and a feature amount axis (hereinafter referred to as “distance between straight lines”); A two-point interval change detection unit 56 that detects a change in the interval between two touched points on the screen (hereinafter referred to as “two-point interval”), and a two-point sliding operation that is touched on the screen of the display panel 12. And a tilt change detecting unit 60 for detecting a change in the tilt of a straight line between two points connecting two touched points on the screen of the display panel 12.

  The action determination unit 20 of the present example performs two points of the touch operation analysis unit 18 while the active state is not being displayed (a period during which no feature amount axis is displayed on the screen of the display panel 12). A feature amount axis selection unit 70 that selects a specific feature amount axis from a plurality of feature amount axes based on the detection result of the touch operation detection unit 50 is included.

  The feature amount axis selection unit 70 of the present example selects a feature amount axis that is closest to the straight line between two points connecting two touched points among the plurality of feature amount axes on the screen of the display panel 12 in an active state. Select as a specific feature axis to be set to.

In addition, the action determination unit 20 of the present example is displaying a specific feature amount axis in an active state on the screen of the display panel 12 (the active state display of any feature amount axis is being performed on the screen of the display panel 12). Based on the detection result of the two-point touch operation detection unit 50, the action is determined as follows, for example.
When the change in the interval between the two points touched on the screen is detected by the two-point interval change detection unit 56, the enlargement / reduction display control unit 46 determines that the feature amount axis is to be enlarged / reduced. In other words, the scale of the feature amount is enlarged for the pinch-out operation during the display in the active state, and the scale reduction of the feature amount is performed for the pinch-in operation during the display in the active state.
When the slide operation detection unit 58 detects two slide operations touched on the screen, the slide display control unit 48 determines to slide the feature amount axis. That is, the feature amount axis is slid in response to the slide operation in the active state.
When a change in the inclination of a straight line connecting two points touched on the screen is detected by the inclination change detection unit 60, the “change of feature amount axis” is performed by the feature amount axis selection unit 70 and the active state display control unit 44. Decide to do. That is, the feature amount axis is changed with respect to the rotation operation during the display of the active state.

  In this example, as the action of the touch operation with respect to the feature amount axis in the active state display, the scale of the feature amount axis is enlarged, the feature amount axis is slid, and the feature amount axis is changed. It is not limited to the case. You may perform actions other than these.

  Specifically, the feature amount axis selection operation by the feature amount axis selection unit 70 includes the following two selection modes.

  (First Selection Mode) Among a plurality of feature amount axes, a feature amount axis having the closest inclination to a straight line between two points connecting two touched points is selected as a specific feature amount axis.

  (Second selection mode) Among a plurality of feature amount axes, the distance from the point-to-point straight line connecting the two touched points is the shortest, and the slope is inclined to the point-to-point straight line connecting the two touched points Is selected as a specific feature amount axis.

  In the first selection mode, when two points for selecting a specific feature amount axis from a plurality of feature amount axes are long touched, two points at positions away from the specific feature amount axis on the screen are long touched. However, there is an advantage that a specific feature amount axis can be selected. Such a first selection mode is effective when a plurality of feature amount axes having substantially the same inclination are not displayed on the screen.

  In the second selection mode, when a plurality of feature amount axes having substantially the same inclination are displayed apart from each other on the screen (for example, one feature amount axis is displayed at each of the left end and the right end of the screen on the same screen). However, it is possible to specify which feature amount axis is selected by two long touches.

  Which of the above two selection modes is adopted is preferably determined by the display mode of the feature amount axis. Even when a plurality of feature amount axes having substantially the same inclination are not displayed on the same screen, the selection mode is switched between the first selection mode and the second selection mode according to the user's setting operation. May be.

<Distance detection between straight lines>
A detection example of a distance between straight lines (a distance between a straight line connecting two touched points on the screen of the display panel 12 and the feature amount axis) detected by the distance detection unit 54 between straight lines will be described.

  As shown in FIG. 3, the distance detection unit 54 between the straight lines of the present example is located on the midpoint P3 of the two touched points P1 and P2 (the two points P1 , P2), the length LD of the perpendicular line perpendicular to the feature axis A is defined as the distance between straight lines.

  Note that the present invention is not limited to the case where the distance LD between straight lines shown in FIG. 3 is directly obtained, and a value (for example, the area between straight lines) corresponding to the LD in FIG. A value corresponding to L may be compared between feature amount axes.

<Select feature axis>
FIG. 4 is a schematic flowchart showing a main part of the image display control process according to the present invention. 4 (steps S1 to S4) are performed under the control of the main control unit 38 in accordance with a program stored in advance in the storage unit 36.

  Step S1 (image display step) is a step of causing the image display control unit 42 to display a plurality of images having a plurality of feature amounts on the screen of the display panel 12, and a plurality of features respectively corresponding to the plurality of feature amounts. This is a step of displaying a plurality of images along the quantity axis.

  In step S2 (feature amount axis selection step), the touch position acquisition unit 16 acquires the touch position from the touch panel 14, and the touch operation analysis unit 18 determines the touch operation type.

  In step S3 (feature quantity axis selection step), when two points are long touched on the screen of the display panel 12, the feature quantity axis selection unit 70 touches at least one of the plurality of feature quantity axes. A feature amount axis that is closest to a straight line connecting two points (a straight line between two points) is selected as a specific feature amount axis.

  In step S4 (active state display step), the active state display control unit 44 performs an active state display on the screen of the display panel 12 to indicate that the selected specific feature amount axis is in an active state that can be touch-operated. .

  As described with reference to FIG. 4, one embodiment of the image display control method of the present invention uses the display panel 12 having a screen, and displays a plurality of images having a plurality of feature amounts on the screen of the display panel 12. The process of displaying a plurality of images along a plurality of feature amount axes respectively corresponding to a plurality of feature amounts and a touch panel 14 for detecting a touch position on the screen of the display panel 12, When two points are touched on the screen, the step of obtaining the touch position of the two points from the touch panel 14 and the feature amount axis closest to the straight line connecting the two points among the plurality of feature amount axes are specified. A step of selecting as a feature amount axis, and a step of performing an active state display on the screen of the display panel 12 indicating that a specific feature amount axis is in an active state capable of being touch-operated. The above-described image display control method is not limited to the case where the image display apparatus 10 of FIG.

  In order to facilitate understanding of the present invention, the description has been made briefly with reference to FIG. 4, but actually, as shown in FIG. 5, processing for touch operations other than feature amount axis selection is also performed.

  In FIG. 5, step S1 (image display step) and step S2 (feature amount axis selection step) are the same as step S1 and step S2 in FIG.

  FIG. 6 shows an image display example in which a plurality of product images M are displayed along a plurality of feature amount axes A1, A2, A3, and A4 as product search results. The first feature amount axis A1 is an axis indicating the hue (also referred to as “hue”) of the product image. The second feature amount axis A2 is an axis indicating the brightness (also referred to as “lightness”) of the product image. The third feature amount axis A3 is an axis indicating the vividness (also referred to as “saturation”) of the product image. The fourth feature amount axis A4 is an axis indicating the pattern type of the product image.

  Next, the touch position acquisition unit 16 acquires the touch position from the touch panel 14, and the touch operation analysis unit 18 determines the touch operation type (step S2).

  Next, the action determination unit 20 determines whether the operation is a feature amount axis selection operation (two long touches in this example).

  FIG. 7 shows a state in which two points P1 and P2 on the first feature amount axis A1 are long touched. The touch operation analysis unit 18 of this example determines whether or not the two points P1 and P2 are long touched. That is, after the two points P1 and P2 are touched, the touch operation analysis unit 18 determines whether or not the touch has continued for a certain time while the two points P1 and P2 remain in the same touch position.

  If the operation is not a feature amount axis selection operation (NO in step S12), the process proceeds to step S14 to execute a general action corresponding to the touch operation. For example, a single tap is performed on a specific product image. If it is broken, an action of enlarging and displaying a specific product image is performed. For example, when a single long touch is performed on a specific product image, an action of displaying attribute information (for example, product name) of the product corresponding to the specific product image is performed. For example, when a pinch-out is performed, a screen enlargement display action corresponding to the amount of pinch-out shift is performed as a so-called zoom-out. For example, when pinch-in is performed, a so-called zoom-in action is performed to reduce the screen according to the amount of pinch-in shift.

  In the case of a feature amount axis selection operation (two-point long touch) (YES in step S12), the processing shown in steps S16 to S20 (the processing corresponding to step S3 in FIG. 4) is performed.

  In this example, the straight line inclination detecting unit 52 detects the inclination of the straight line between two points connecting the two touched points P1 and P2 on the screen of the display panel 12 (step S16), and the straight line distance detecting unit. 54, the distance between straight lines between the straight line between the two points P2 and P2 touched on the screen of the display panel 12 and each of the plurality of feature amount axes A1 to A4 is detected (step S18). By the feature amount axis selection unit 70, the distance between the touched two points P1 and P2 and the touched two points P1 among the plurality of feature amount axes A1 to A4 is the smallest. , P2 is selected as the specific feature amount axis with the closest feature amount axis to the straight line between the two points (step S20).

  Next, the active state display control unit 44 performs an active state display on the display panel 12 to indicate that the selected specific feature amount axis is in an active state in which a touch operation is possible (step S4). In other words, the active state display control unit 44 determines that the specific feature amount axis is in the active state when two points of touch are continued for a certain period of time, and performs the active state display.

  FIG. 8 shows an example of the active state display. In this example, the feature amount axis A1 is displayed by displaying the selected specific feature amount axis A1 in a color that is thicker than the unselected feature amount axes A2 to A4 and different from the unselected feature amount axes A2 to A4. Displays the active status of. Further, in this example, the product image M is transmitted and displayed on the feature amount axis A1 so that the product image M is hidden from view on the feature amount axis A1 thickened in the active state display. The active state display is not limited to such an example. For example, it includes a case where the specific feature amount axis A1 is simply displayed with a color different from the non-selected feature amount axes A2 to A4. Or you may display the specific feature-value axis | shaft A1 only by the line | wire type (for example, dotted line) different from the non-selected feature-value axis | shafts A2-A4.

  Next, processing during active state display is performed (step S22).

  Further, it is determined whether or not to end this process (step S24). If it is determined not to end (NO in step S24), the process returns to step S2, and if it is determined to end (in step S24). If YES, this process ends.

<Processing during active status display>
FIG. 9 is a flowchart showing an example of step S22 (processing during active state display) of FIG.

  First, during the active state display, the two-point interval change detection unit 56 detects a change in the interval between the two touched points P1 and P2 on the screen of the display panel 12 (step S42). When the interval between the two points P1 and P2 changes (YES in step S42), the scale of the feature amount axis is enlarged or reduced by the enlargement / reduction display control unit 46 (step S44). In other words, when a change in the interval between the two points P1 and P2 is detected during the active state display, the action determination unit 20 determines “feature axis expansion / contraction” as an action, and the expansion / contraction display control unit 46 determines whether the display panel 12 The scale of a specific feature amount axis is enlarged or reduced according to the change amount of the interval between the two points P1 and P2 on the screen.

  For example, during the active state display shown in FIG. 8, a touch operation (pinch out) is performed to widen the distance between the two points P1 and P2 while maintaining the touch of the two points P1 and P2 as shown in FIG. In this case, the scale of the selected first feature amount axis A1 is enlarged. As a result, the interval between the product images M along the selected first feature amount axis A1 is widened. Note that the feature amount axis in the figure does not have a scale, but when the feature amount axis has a scale, the interval between the scales becomes wide.

  For example, during the active state display shown in FIG. 8, when a touch operation (pinch-in) is performed to narrow the distance between the two points P1 and P2 while the touch of the two points P1 and P2 is maintained as shown in FIG. The scale of the selected first feature amount axis A1 is reduced. As a result, the interval between the product images M along the selected first feature amount axis A1 is narrowed. Note that the feature amount axis in the figure does not have a scale, but when the feature amount axis has a scale, the interval between the scales is also narrowed.

  Further, during the active state display, the slide operation detection unit 58 detects the slide of the two points P1 and P2 that are touched on the screen of the display panel 12. When the slide of the two points P1 and P2 is detected (YES in step S46), the slide of the feature amount axis is performed by the slide display control unit 48 (step S48). In other words, when the slide operation detection unit 58 detects the slide at the two points P1 and P2 during the active state display, the action determination unit 20 determines “slide of the feature amount axis” as the action, and the slide display control unit 48 Thus, the specific feature amount axis is slid in the axial direction of the feature amount axis in accordance with the slide amount of the two points P1 and P2 on the screen of the display panel 12.

  For example, when the center point between the two points P1 and P2 moves while the touch of the two points P1 and P2 is maintained as shown in FIG. 12 during the active state display shown in FIG. The axis A1 is slid in the axial direction of the feature amount axis A1 according to the sliding amount of the touch.

  Further, during the active state display, the inclination change detection unit 60 detects a change in the inclination of the straight line between the two points connecting the touched two points P1 and P2 on the screen of the display panel 12 (step S50). When the interval between the two points P1 and P2 changes (YES in step S50), the feature amount axis is changed by the feature amount axis selection unit 70 and the active state display control unit 44 (step S52). That is, when a change in the slope of a straight line between the two points P1 and P2 is detected during the active state display, the action determining unit 20 determines “change feature amount axis” as an action, and selects the feature amount axis. The feature amount axis adjacent to the specific feature amount axis displayed in the active state by the unit 70 in the direction of rotation is selected as a new specific feature amount axis. When a new specific feature amount axis is selected, the active state display control unit 44 cancels the active state display of the feature amount axis being displayed in the active state, and displays the active state display of the new specific feature amount axis.

  For example, during the active state display shown in FIG. 8, the touch operation (rotation) that changes the inclination of the straight line between the two points P1 and P2 while the touch of the two points P1 and P2 is maintained as shown in FIG. ) Is released, the active state display of the first feature amount axis A1 that is actively displayed is canceled, and the second feature amount that is adjacent to the first feature amount axis A1 in the rotation direction is released. The axis A2 is selected as a new specific feature amount axis, and the active state display of the second feature amount axis A2 is performed.

  Further, it is determined whether an operation for canceling the active state has been performed during the active state display (step S54). The active state cancellation may be performed, for example, by displaying a button for canceling the active state on the screen of the display panel 12 and when the button is tapped, or a special touch operation (for example, one-point touch). (Rotation). When the touch operation for canceling the active state is performed (YES in step S54), the active state is canceled in step S56. In this active state cancellation, a new feature amount axis is not selected. If the touch operation for canceling the active state has not been performed (NO in step S54), the process returns to step S42.

  As described above, this example assigns two long touches to the “select feature axis” operation and performs the active display of the selected feature axis. It is preferable in that the example operation for the feature amount axis following can be performed by a continuous simple touch operation. In other words, the scale of the feature axis can be expanded by pinching out continuously after two long touches, and the scale of the feature axis can be expanded by pinching in two consecutive long touches. It can be reduced, and the feature axis can be slid by sliding two points in succession to two long touches, and by rotating continuously in two long touches The quantity axis can be changed.

  The present invention is not limited to the case where two long touches are assigned to the “select feature axis” operation. A two-point touch operation other than the two-point long touch may be assigned to the feature amount axis selection operation. For example, a mode in which it is determined that a “feature axis selection” operation has been performed when two point taps (a touch operation in which two points are simultaneously touched and two points are simultaneously released) is performed.

<Variation>
In the above-described embodiment, a case where a plurality of feature amount axes are displayed on the screen of the display panel and a plurality of images are displayed superimposed on the displayed feature amount axes has been described as an example. Is not limited.

  A plurality of feature amount axes may be hidden on the display panel screen, and a plurality of images may be displayed along the non-displayed feature amount axes.

  FIG. 14 shows an example of image display when the feature amount axis is not displayed. The feature amount axes A1, A2, A3, and A4 drawn with dotted lines in the figure are not displayed on the screen of the display panel 12. Even if the feature amount axis is not displayed, if a plurality of images are displayed in a straight line along the feature amount axis, the user can determine the position of the hidden feature amount axis from the plurality of aligned images. I can grasp it. Therefore, as shown in FIG. 15, it is possible to perform a feature amount axis selection operation (for example, selection of the feature amount axis A1) by a long touch of the two points P1 and P2. As shown in FIG. 16, the active state display control unit 44 performs an active state display D1 corresponding to a specific feature amount axis A1 selected by the feature amount axis selecting unit 70.

≪Other aspects of feature axis selection≫
In the above-described embodiment, the case of detecting the inclination of a straight line connecting two touched points has been described as an example, but the present invention is not limited to such a case.

  The two-point touch operation detection unit 50 determines whether there is a feature amount axis where both of the two touched points are located on the axis, and both of the two touched points are located on the axis. The feature amount axis may be determined to be “a specific feature amount axis whose inclination is closest to a straight line connecting two points”.
