Description

  The present invention relates to a user interface for performing a zoom operation in an information processing apparatus.

  When zooming with a video camera or editing device, the conventional zoom operation method cannot achieve the desired zoom speed, so the subject cannot be captured at the desired size. Adjustment by repetition is necessary. In a conventional information processing apparatus, there has been proposed a method for automatically performing zooming processing when the user specifies a zoomed composition or magnification. For example, Patent Document 1 proposes a method for determining the magnification after zooming. Patent Document 2 proposes a method for calculating an optimum angle of view necessary for making a human image a target size.

JP 2004-252370 A JP2008-252711

  According to the technique disclosed in Patent Document 1, since the device automatically performs zooming processing after the user determines the zoomed magnification, the problem that it is difficult to adjust the zoom speed is solved. Further, according to the technique disclosed in Patent Document 2, there is an advantage that the method of specifying the composition after zooming becomes easy when the image is a human image.

  However, none of the techniques considers a method for easily specifying the zoom speed. In particular, it is necessary to be able to easily set the zoom speed in consideration of the case where the zoom speed is changed every time the user performs zoom processing.

  The present invention has been made in view of such circumstances, and an object of the present invention is to allow easy specification of a zoomed magnification and a zoom speed after zooming.

In order to solve the above problems, the present invention provides:
A designation means for simultaneously designating a zoom magnification and a zoom speed;
Magnification interpretation means for interpreting the zoom magnification according to the specification;
Speed interpretation means for interpreting the zoom speed according to the designation;
Zooming processing means for performing zooming processing at the zoom speed interpreted by the speed interpretation means based on the zoom magnification interpreted by the magnification interpretation means.

  Since zoom magnification and zoom speed can be specified at the same time, zoom control can be performed smoothly.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Example 1
FIG. 1 shows an example of a configuration diagram of an information processing apparatus according to the present invention. As illustrated in FIG. 1, the information processing apparatus according to the present exemplary embodiment includes a display unit 101, an operation unit 102, a control unit 103, a storage unit 104, and a zoom control unit 105.

  The display unit 101 includes a display device such as a liquid crystal display or a CRT display, and displays various types of information including images, characters, and the like. When a touch panel display device is used, it also has a function as an operation unit 102 described later.

  The operation unit 102 includes input devices such as various switches, buttons, a touch panel, a pen, and a tablet, and functions as an input interface for inputting various instructions and text data to the information processing apparatus.

  The control unit 103 includes a work memory (for example, a RAM), a CPU, an MPU, a ROM, and the like, and reads various programs and data stored in the storage unit 104 and executes various processes.

  The storage unit 104 includes a hard disk drive device for storing various types of information and a storage medium such as a CD-ROM or DVD-ROM for providing various types of information to the information processing system.

  The zoom control unit 105 is a device that controls zooming processing. When the information processing apparatus is a digital camera, it is composed of a lens group and an apparatus for driving and controlling the lens in the case of optical zoom, and is composed of an image processing apparatus in the case of digital zoom. When the information processing apparatus is an editing apparatus, the image processing apparatus is configured as in the case of the digital zoom described above.

  Next, an operation example of the information processing apparatus according to the first embodiment having the above configuration will be described with reference to FIGS.

  FIG. 2 is a flowchart showing the basic operation procedure of the zoom process of the information processing apparatus according to this embodiment.

  First, in step S201, the zoom magnification and the zoom speed are simultaneously designated by the user's operation (designating means).

  Subsequently, the zoom magnification designated in the preceding step S201 is interpreted (step S202: zoom magnification interpreting means).

  Next, the zoom speed designated in step S201 in the preceding stage is interpreted (step S203: zoom speed interpretation means).

  Subsequently, the zoom control unit 105 performs zooming processing at the zoom speed interpreted in step S203 until the zoom magnification interpreted in step S202 is reached (step S204: zooming processing unit).

  FIG. 3 shows an operation example of the information processing apparatus in the present embodiment. In FIG. 3A, zoom magnification candidates 301 to 303 are displayed in advance on the display unit 101 of the digital camera. The zoom magnification candidate may be a predetermined magnification (for example, 1.5 times / 2 times / 2.5 times), or an optimum field angle candidate (for example, a person image) calculated by using an existing technique. In this case, waist up / bust up / face up, etc.) may be used. When the user enters a number on any of the zoom magnification candidates 301 to 303 using a stylus or a finger, the magnification and speed after zooming are simultaneously designated.

  The zoom magnification interpretation means interprets the magnification of the candidate with the numeral entered above among the zoom magnification candidates 301 to 303 as the zoom magnification.

  Next, FIG. 4 shows a flowchart relating to the processing of the zoom speed interpretation means in the first embodiment. FIG. 4 corresponds to the sub-flow in step S203 of FIG.

  First, in step S401, the number entered by the user is recognized using existing character recognition technology. The recognized number is treated as the number of seconds to zoom.

  Subsequently, in step S402, a zoom speed (zoom speed = zoom amount / specified time) is calculated so that zooming can be performed in the specified time. For example, when zooming in 2.5 times in 3 seconds, the zoom speed is 2.5 times / 3 seconds. At this time, the zoom speed may be set to the closest value among the predetermined zoom speeds. For example, when “0” is input, the zoom speed is set to the maximum speed.

  FIG. 3B shows an example in which the user enters the number “2” on the zoom magnification candidate 302 with the finger. By this user operation, zoom is performed for 2 seconds at the magnification set in 302. Similarly, FIG. 3C shows an example in which the user writes a number “3” on the zoom magnification candidate 303 using a finger. By this user operation, zooming is performed for 3 seconds at the magnification set in 303.

  As described above, according to the first embodiment, since the zoom magnification and the zoom speed can be specified at the same time, the zoom speed can be easily set even when the user changes the zoom speed each time the zoom process is performed.

(Example 2)
In the first embodiment, the example in which the zoom speed is specified by the time required for zooming has been described. On the other hand, in the present embodiment, an example will be described in which designation of the zoom speed is designated by a predetermined character or symbol.

  FIG. 5 shows an operation example of the information processing apparatus in the present embodiment. Basically, as in FIG. 3A, zoom magnification candidates 301 to 303 are displayed in advance on the display unit 101 of the digital camera. The difference from the examples (b) and (c) of FIG. 3 is the processing of the interpretation means of the zoom speed, and a flowchart of this processing is shown in FIG. FIG. 6 corresponds to the subflow of step S203 of FIG.

  First, in step S601, characters entered by the user are recognized using existing character recognition technology. In this case, the characters entered by the user are not limited to numbers such as alphabets and symbols.

  In step S602, the zoom speed is determined according to the recognized character according to a predetermined rule. Next, the rules will be described. When a character is assigned to each zoom speed setting candidate and the corresponding character is recognized, the zoom speed is determined to the corresponding value. For example, if the rule is “speed 1” if the character is “1” and “speed 2” if the character is “2”, the zoom speed is set to “speed 1” when the user enters “1”. decide. Similarly, if the rule is “zoom speed 1” if the letter is “H”, and “zoom speed 5” if the letter is “L”, the zoom speed is set to “zoom” when the user enters “L”. The speed is determined as 5 ′.

  FIG. 5 shows an example in which the user enters the number “2” on the zoom magnification candidate 302 using the finger. By this user operation, zooming is performed at the zoom speed “speed 2” to the magnification set in 302.

  As described above, according to the second embodiment, similarly to the first embodiment, the zoom magnification and the zoom speed can be specified at the same time. Therefore, even when the user changes the zoom speed every time the zoom process is performed, the zoom speed is easy. Can be set.

(Example 3)
In the first and second embodiments, the example in which the zoom magnification candidates are displayed in advance on the display unit 101 and the user selects them has been described. In contrast, in this embodiment, an example in which the user specifies the zoom magnification and the zoom speed when the zoom magnification candidates are not displayed in advance will be described.

  FIG. 7 shows an operation example of the information processing apparatus in the present embodiment. FIG. 4A is an example of zooming in, and FIG. 4B is an example of zooming out. The operation at this time will be described with reference to the flowchart shown in FIG.

  The user designates the zoom magnification by designating a range on the display unit 101 (702, 707, step S801). The information processing apparatus recognizes the designated range and calculates an optimal rectangle that fits the designated screen. Specifically, among the quadrangles having the aspect ratio of the screen (image), the smallest quadrangle including the designated range is calculated (step S802). The zoom magnification is calculated based on the size of the quadrangle and whether the zoom-in or zoom-out is determined later.

  Subsequently, the calculated rectangle and zoom icon (T and W) are displayed on the display unit 101 (703, 708, step S803).

  Next, when a character is entered on the zoom icon by a user operation (704, 709, step S804), the process proceeds to step S805.

  In step S805, zoom-in or zoom-out is determined depending on which icon of the zoom icons (T and W) is written. Here, when the number is entered on T, it is determined that the zoom-in is performed, and when the number is entered on W, it is determined that the zoom-out is performed. In the case of zooming in, the zoom factor is the magnification when zooming in until the size of the rectangle displayed in step S803 becomes the screen size. In the case of zooming out, the zoom magnification is the magnification when zooming out until the screen size reaches the size of the calculated rectangle displayed in step S803.

  Subsequently, it is determined whether or not the zoom magnification calculated in step S805 is within a zoomable range (step S806). If it is within the zoomable range (YES in step S806), the zoom magnification calculated in step S805 is used as it is, and the process proceeds to step S808. On the other hand, if it is not within the zoomable range (NO in step S806), the zoom magnification is determined as the limit value and a notification to that effect is sent (step S807). For example, if the designated zoom magnification is 3.5 times, but the zoomable range is up to 2 times, the zoom magnification is determined to be 2 times and notification to that effect.

  Subsequently, the character is recognized and the zoom speed is interpreted (step S808). For the interpretation method of the zoom speed, the method described in the first embodiment or the second embodiment is used.

  Subsequently, the zoom control unit 105 performs zooming processing at the zoom speed set in step S808 until the zoom magnification determined in step S806 or step S807 is reached (step S809). At this time, as shown by a slider bar 901 in FIG. 9, display is performed so that the user can know the current magnification, the magnification 902 before zooming, the magnification 903 after zooming, and the zoom direction (arrow). When zooming is performed automatically, it is difficult for the user to understand the zoom status, but by presenting such information, the user can easily grasp the zoom status.

  As described above, according to the third embodiment, similarly to the first and second embodiments, the zoom magnification and the zoom speed can be specified at the same time. Therefore, even when the user changes the zoom speed every time the zoom process is performed. Zoom speed can be set easily.

Example 4
In the third embodiment, an example in which the user specifies the zoom magnification and the zoom speed at the same time when the zoom magnification candidates are not displayed in advance has been described. Among them, in the third embodiment, an example is shown in which a square and a zoom icon (T and W) are displayed in response to a user range input. On the other hand, in this embodiment, an example in which only a square is displayed in response to a user's range input will be shown.

  FIG. 10 shows an operation example of the information processing apparatus in the present embodiment. FIG. 4A is an example of zooming in, and FIG. 4B is an example of zooming out. In this figure, the points different from FIG. 7 are the parts indicated by reference numerals 1001 to 1004. The same parts as those in FIG.

  The operation at this time will be described with reference to the flowchart shown in FIG. Similarly in FIG. 11, the same parts as those in FIG. 8 are denoted by the same reference numerals as those in FIG. 8 (steps S801, 802, 806 to 809). Here, only the parts different from the third embodiment (steps S1101 to 1103) will be described.

  In this embodiment, when a square is calculated in step S802, the calculated square is displayed on the display unit 101 (1001, 1003, step S1101).

  Next, when a character is entered on the display unit 101 by a user operation (1002, 1004, step S1102), the process proceeds to step S1103.

  In step S1103, either zoom-in or zoom-out is determined according to the relative position of the character with respect to the rectangle displayed in step S1101. For example, as shown in FIG. 12, whether a character is above or below the line segment 1201 is determined based on a line segment 1201 connecting the midpoints of the vertical sides of the rectangle. Specifically, the area 1203 above the line segment 1201 and the area 1204 below the line segment 1201 in the entire character area 1202 are compared. If the upper area 1203 is larger, the zoom-in is determined, and if the lower area 1204 is larger, the zoom-out is determined. If the areas are the same, processing such as having the user fill in again is performed. In the case of zooming in, the zoom factor is the magnification when zooming in until the size of the rectangle displayed in step S1101 reaches the screen size. In the case of zooming out, the zoom magnification is the magnification when zooming out until the screen size reaches the size of the calculated rectangle displayed in step S1101. Thereafter, the process proceeds to step S806, and is the same as in the third embodiment.

  As described above, according to the fourth embodiment, the zoom magnification and the zoom speed can be specified at the same time as in the first to third embodiments. Therefore, even when the user changes the zoom speed every time the zoom process is performed, the zoom speed is increased. Can be set easily.
