Description

    The present invention relates to an imaging apparatus and an imaging apparatus program that capture an image and generate electronic image data of the image.

  In recent years, in a digital camera that captures an image and generates electronic image data, the height (length in the vertical direction) of an image display area of a display unit realized by using a liquid crystal panel or the like is the height of the digital camera. It has grown to almost the same level. Under such circumstances, a technique for providing a function as a graphical user interface (GUI) by stacking a touch panel on a display unit has been considered. Specifically, for example, a technique for enlarging and displaying an image of a part touched on the display unit while the display unit is displaying an image is known (for example, Patent Documents 1 and 2). reference). According to this technique, by displaying an enlarged portion of the image displayed by the display unit where the image quality cannot be sufficiently determined, it is possible to accurately grasp the image quality of the image.

   2 to 4 are diagrams illustrating an outline of a first process characteristic of the imaging apparatus 1. Among these, FIG. 2 shows a state in which the imaging apparatus 1 is set to the reproduction mode and the reproduction image 101 in which the adult and the child are photographed together is displayed on the display unit 4. When the user touches the finger 201 on the child's face 111 in this state, the display unit 4 displays the composite image 102 generated by superimposing the enlarged image 121 on the reproduced image 101 as shown in FIG. The The enlarged image 121 is arranged in a region that does not overlap the contact position with the finger 201 (upper right portion in FIG. 3). Thereafter, when the user removes the finger 201 from the display unit 4, the enlarged image 121 is deleted on the display unit 4 and the reproduced image 101 is displayed again as shown in FIG. As described above, in the first embodiment, an enlarged image of a face is displayed just by touching a finger on the position of the face to be enlarged in the reproduced image. On the other hand, when the touch on the face is released, the enlarged image is instantly enlarged. The image disappears and the original playback image is restored. Therefore, it is possible to easily display and delete the enlarged image with one finger.

   5 to 7 are diagrams illustrating an outline of the second processing characteristic of the imaging apparatus 1. Among these, FIG. 5 shows a state in which the user touches a part other than the human faces 111 and 112 while displaying the same reproduced image 101 as in FIG. If the finger 201 is slid rightward while touching the display portion of the face 111 in this state, the touch position in the reproduced image 101 does not change as shown in FIG. 6, and the reproduced image 101 matches the movement of the finger 201. Shift to the right. A playback image 103 having a face 113 is connected to the playback image 101 at the left end in the width direction of the display unit 4 to which the playback image 101 has been shifted (the end on the rear side in the direction in which the contact position changes). Two reproduced images 101 and 103 constitute a continuous image 104. The reproduced image 103 is an image taken after the reproduced image 101, for example. When the finger 201 is further shifted rightward and eventually the finger 201 protrudes from the display unit 4, the display unit 4 displays the reproduced image 103 on the full screen as shown in FIG. As described above, in the first embodiment, images can be switched by sliding a finger while touching a position other than the face with the finger in a reproduced image. When the finger 201 is shifted to the left side, the reproduced image 103 may be continuously displayed on the right side of the reproduced image 101. In addition, depending on the direction in which the finger 201 is shifted, the image may be switched to one of images captured before and after the reproduced image 101.

   FIG. 8 is a flowchart illustrating an outline of processing when the imaging apparatus 1 is set to the shooting mode or the playback mode. First, when the imaging device 1 is set to the shooting mode (step S1: shooting mode), the display unit 4 displays an image (through image) captured by the imaging unit 2 (step S2).

  After that, the face detection unit 31 detects the face of a person present in the through image, and records face information such as the detected face position, height, width, etc. in the face information storage unit 72 (step S3). In step S <b> 3, the face detection unit 31 detects the presence or absence of a human face in the through image by performing template matching using the face template stored in the template storage unit 73. When the face detection unit 31 detects a face (step S3: Yes), the enlargement rate calculation unit 32 calculates the face enlargement rate M based on the face information of the face (step S4). Here, the face enlargement ratio M is given by M = W / (2F), where F is the height of the face detected by the face detection unit 31 and W is the screen width of the display unit 4. This definition formula means that a square region having a side length of F is expanded to a square region having a side length of W / 2, that is, half the width of the display unit 4. When the face detection unit 31 does not detect a face in the through image (step S3: No), the imaging device 1 proceeds to step S5.

  Subsequently, the control unit 8 performs focus adjustment (step S5). If the face detection unit 31 detects a human face, the control unit 8 performs control to focus on the detected face position.

  Thereafter, when a release button that forms a part of the input unit 5 is pressed and a release signal is input (step S6: Yes), the imaging unit 2 captures an image under the control of the control unit 8 ( Step S7). Thereafter, the control unit 8 adds information such as the data generation date and time to the image data generated by the imaging unit 2 and subjected to image processing by the image processing unit 3 with reference to the output of the clock 6, and the image data It records in the memory | storage part 71 (step S8). If the release button is not pressed in step S6 (step S6: No), the imaging device 1 returns to step S1.

  After step S8, when an end instruction to end shooting is input by the input unit 5 (step S9: Yes), the imaging apparatus 1 ends a series of processes. On the other hand, when an instruction to end shooting is not input by the input unit 5 (step S9: No), the imaging apparatus 1 returns to step S1.

  Next, a case where the imaging device 1 is set to the playback mode (step S1: playback mode) will be described. In this case, the imaging apparatus 1 reproduces and displays the captured image selected and input by the user via the input unit 5 on the display unit 4 (step S10).

  Thereafter, when the touch panel 51 detects an external contact with the display unit 4 (hereinafter referred to as “the touch panel 51 detects a contact from the outside”) (step S11: Yes), the determination unit 81 sets the face information storage unit 72. By referencing, it is determined whether or not a face is displayed at the operation signal input position of the touch panel 51, that is, the external contact position (hereinafter referred to as "contact position") with respect to the display unit 4 (step S12). In other words, the determination unit 81 determines whether or not the contact position is included in the face display area in the image being displayed on the display unit 4. If the determination unit 81 determines that a face is displayed at the contact position (step S12: Yes), the enlarged image generation unit 33 enlarges the face specified by the signal from the touch panel 51 at an enlargement ratio M. Then, an enlarged image of the face is generated (step S13). On the other hand, if the determination unit 81 determines that no face is displayed at the contact position (step S12: No), the imaging apparatus 1 proceeds to step S19.

  In step S11, when the touch panel 51 does not detect external contact with the display unit 4 (step S11: No), the imaging device 1 proceeds to step S24.

  After step S13, the composite image generation unit 34 generates a composite image by superimposing the enlarged image on a predetermined position of the reproduced image (step S14). FIG. 9 is a diagram showing the relationship between the contact position on the display unit 4 and the main display area of the enlarged image in the composite image. The first to fourth quadrants described in the table Tb shown in FIG. 4 indicate the display area divisions when the rectangular display unit 4 is divided into two equal parts vertically and horizontally. More specifically, as shown in FIG. 10, when the display unit 4 is divided into four equal parts as described above, the upper right part is the first quadrant, the upper left part is the second quadrant, the lower left part is the third quadrant, and the lower right part is The fourth quadrant. Next, the main display area will be described. The main display area is an area where the entire area is filled with the enlarged image. As described in step S <b> 4, the enlarged image is displayed in a square area in which the length of one side is ½ of the width W of the display unit 4. For this reason, when the contact position is in the first quadrant, as shown in FIG. 11, the enlarged image is superimposed on a square area D in which a partial area of the second quadrant is added to the entire area of the third quadrant. Accordingly, the main display area in this case is the third quadrant.

  Here, the main display area when the touch from the outside on the boundary line between two quadrants adjacent to the touch panel 51 is detected will be described. First, when the contact position is on the boundary line between the first quadrant and the second quadrant, the main display area is set to the third quadrant. Next, when the contact position is on the boundary line between the first quadrant and the fourth quadrant, and when the contact position is on the boundary line between the third quadrant and the fourth quadrant, the main display area is set as the second quadrant. Finally, when the contact position is on the boundary line between the second quadrant and the third quadrant, the main display area is set to the first quadrant. When the contact position is the boundary of the first to fourth quadrants, that is, the center of the display unit 4, the main display area is set to the second quadrant.

  Subsequent to step S14, the display unit 4 displays the composite image generated by the composite image generation unit 34 (step S15). Here, a display example of a composite image will be described with reference to FIGS. In the reproduced image 101 shown in FIG. 2, the child's face 111 belongs to the third quadrant of the display unit 4. Therefore, when the user touches the display area of the face 111 with the finger 201, the composite image generation unit 34 determines the main display area of the enlarged image 121 as the first quadrant with reference to the table Tb, as shown in FIG. A composite image 102 is generated. Note that when the user touches the display area of the face 112 with the finger 201, the face 112 belongs to the second quadrant of the display unit 4, so the composite image generation unit 34 selects the main display area of the enlarged image of the face 112. A composite image is generated as the fourth quadrant.

  Thereafter, when the touch panel 51 detects contact from the outside (step S16: Yes), the display unit 4 displays a composite image (step S17: Yes) if a face is displayed at the contact position (step S17: Yes). S15) is continued.

  On the other hand, when the touch panel 51 detects contact from the outside (step S16: Yes) and no face is displayed at the contact position (step S17: No), the display unit 4 redisplays the image before composition. (Step S18). The image to be redisplayed here is, for example, a reproduced image 101 shown in FIG. In step S16, when the touch panel 51 does not detect external contact with the display unit 4 (step S16: No), the imaging device 1 proceeds to step S23.

  Thereafter, when the contact position has changed in the width direction of the display unit 4 within a predetermined time (step S19: Yes), the display unit 4 is reproducing the next candidate image under the control of the control unit 8. The continuous image connected to the image is slid in accordance with the change of the contact position (step S20). The continuous image here is, for example, the continuous image 104 shown in FIG. On the other hand, if the contact position is stationary without changing in the width direction of the display unit 4 within a predetermined time (step S19: No), the imaging device 1 proceeds to step S22.

  Subsequent to step S20, when the touch panel 51 detects an external contact (step S21: Yes), the imaging device 1 returns to step S19. On the other hand, when the touch panel 51 does not detect contact from the outside (step S21: No), if the switching of the displayed image is not completed (step S22: No), the display unit 4 displays the pre-combination image. Is displayed again (step S23). The reason why the pre-combination image is displayed again is that the finger 201 has been released while the continuous image is displayed. In step S23, the next candidate image may be switched to be displayed.

  Thereafter, when an instruction to end reproduction is input from the input unit 5 (step S24: Yes), the imaging device 1 ends a series of processes. On the other hand, when the reproduction end instruction is not input from the input unit 5 (step S24: No), the imaging apparatus 1 returns to step S1.

  After step S20, if the touch panel 51 does not detect contact from the outside (step S21: No) and switching of the displayed image is completed (step S22: Yes), the imaging device 1 performs step S24. Proceed to Here, the state where the image has been switched is a state as shown in FIG. 7, for example.

  According to Embodiment 1 of the present invention described above, the combined image obtained by combining the enlarged images on the display unit 4 is displayed only while contact from the outside occurs on the face portion to be enlarged, Thereafter, when there is no contact from the outside, the pre-combination image is redisplayed, so that a part of the image displayed on the display unit 4 is enlarged and displayed, and then easily and quickly returned to the original display state. It is possible to reproduce and display a plurality of images with a good tempo.

  Further, according to the first embodiment, since the main display area of the enlarged image is determined according to the external contact position detected by the touch panel 51, the position that is easy to see with the least interference with the touched finger or the like Can display an enlarged image.

  Further, according to the first embodiment, it is possible to switch images by simply changing the touched position while touching a position where a face other than the face is displayed on the display unit 4 with a finger. Therefore, continuous image reproduction can be easily performed. Therefore, it is possible to use the imaging device 1 as an album substitute.

  In the first embodiment, the relationship between the contact position and the main display area shown in FIG. 9 is merely an example. For example, when the contact position is in the right half (first and fourth quadrants) of the display unit 4, the enlarged image is displayed in the third quadrant, while the contact position is in the left half (second and third quadrants) of the display unit 4. (Quadrant), an enlarged image may be displayed in the first quadrant.

(Embodiment 2)
The second embodiment of the present invention is different from the first embodiment in the composite image display mode when the user touches the face of a desired person on the display unit of the imaging apparatus. The imaging apparatus according to the second embodiment has the same components as the imaging apparatus 1 according to the first embodiment, although there are some functional differences. Therefore, in the following description, components corresponding to the components of the imaging device 1 described above will be described with the same reference numerals.

FIG. 12 is a flowchart illustrating an outline of processing when the imaging apparatus 1 is set to the shooting mode or the playback mode. The processes in steps S32 to S39 performed when the imaging apparatus 1 is set in the shooting mode (step S31: shooting mode) sequentially correspond to the processes in steps S2 to S9 in FIG. However, the enlargement factor M ₂ of the image calculated by the enlargement factor calculator 32 in step S34 is defined as M ₂ = H / F where the height of the display unit 4 is H. When this enlargement factor M ₂ is used, a square region having a side length of F is expanded to a square region having a side length of H.

  Next, the case where the imaging device 1 is set to the playback mode will be described (step S31: playback mode). In this case, the imaging apparatus 1 reproduces and displays the captured image selected by the input from the input unit 5 on the display unit 4 (step S40).

Thereafter, when the touch panel 51 detects contact (step S41: Yes), the determination unit 81 refers to the face information storage unit 72 to determine whether or not a face is displayed at the contact position (step S42). If the result of the determination unit 81 determines, for the face to the contact position is displayed (step S42: Yes), the enlarged image generating unit 33 to expand the face specified by a signal from the touch panel 51 at a magnification M ₂ Thus, an enlarged image of the face is generated (step S43). On the other hand, if the determination unit 81 determines that no face is displayed at the contact position (step S42: No), the imaging apparatus 1 proceeds to step S51.

  If the touch panel 51 does not detect contact from the outside in step S41 (step S41: No), the imaging device 1 proceeds to step S56.

  After step S43, the composite image generation unit 34 generates a composite image by superimposing the enlarged image on a predetermined position of the reproduced image (step S44). FIG. 13 is a diagram illustrating an example of a composite image generated by the composite image generation unit 34. A composite image 105 shown in the figure is generated when the user touches the finger 201 on the face 111 while the display unit 4 is displaying the reproduced image 101 shown in FIG. Specifically, the composite image 105 is an image in which the enlarged image 151 is superimposed on the right side of the face 111 of the reproduced image 101. When the contact position is in the second and third quadrants of the display unit 4 (see FIG. 9), the enlarged image 151 is arranged so that the left end portion is on the right side by a predetermined distance from the contact position. On the other hand, when the contact position is in the first and fourth quadrants of the display unit 4, the right end part is arranged on the left side by a predetermined distance from the contact position. The width W ′ of the composite image 105 generated in this way is larger than the width W of the display unit 4. For this reason, the display unit 4 cannot display the entire picture of the composite image 105, and a part thereof is cut out and displayed.

   Subsequently, the display unit 4 displays the composite image 105 generated by the composite image generation unit 34 (step S45). FIG. 14 is a diagram illustrating a display example of the composite image 105 on the display unit 4. In the composite image 105A shown in the figure, the reproduction image 101 is displayed at the original reproduction position, and the enlarged image 151 displays only the left half area.

  Thereafter, when the touch panel 51 detects an external contact (step S46: Yes), the determination unit 81 refers to the face information storage unit 72 to determine whether or not a face is displayed at the contact position (step S47). ).

  If the determination unit 81 determines in step S47 that a face is displayed at the contact position (step S47: Yes), the contact position changes in the width direction of the display unit 4 within a predetermined time (step S48: Yes). The display unit 4 slides and displays the composite image according to the change of the contact position under the control of the control unit 8 (step S49). FIG. 15 is a diagram illustrating a display example of the composite image 105 when the finger 201 is slid to the left in the width direction from the state illustrated in FIG. In the composite image 105B shown in FIG. 15, the area occupied by the enlarged image 151 is larger than that of the composite image 105B. Therefore, the composite image 105B can more accurately grasp the appearance of the face 111 than the composite image 105A. Thereafter, the imaging apparatus 1 returns to step S46.

  On the other hand, as a result of the determination by the determination unit 81 in step S47, when the face is not displayed at the contact position (step S47: No), the display unit 4 redisplays the display image before composition (step S50). The processes in steps S51 to S56 subsequent to step S50 sequentially correspond to the processes in steps S19 to S24 described with reference to FIG.

  If the touch panel 51 does not detect contact from the outside in step S46 (step S46: No), and if there is no change in the width direction of the contact position within a predetermined time in step S48 (step S48: No), the imaging device 1 Proceed to step S55.

  According to the second embodiment of the present invention described above, as in the first embodiment, after the part of the image displayed on the display unit 4 is enlarged and displayed, it can be easily and quickly returned to the original display state. It is possible to revert and to display and display a plurality of images with a good tempo.

  Further, according to the second embodiment, since the enlargement ratio of the enlarged image is larger than that of the first embodiment, it is possible to grasp the appearance of the face more reliably.

(Other embodiments)
As described above, the first and second embodiments have been described in detail as the best mode for carrying out the present invention. However, the present invention should not be limited only by the two embodiments. For example, the size of the enlarged image may be changed according to the finger slide. FIG. 16 is a diagram illustrating a display example of an enlarged image in this case. In the composite image 106A shown in the figure, an enlarged image 161A is displayed on the right side of the finger 201. This is because the area on the right side of the finger 201 is wider than the area on the left side of the finger 201 in the display unit 4 shown in FIG. Thereafter, when the finger 201 is slid to the left in the width direction while touching the display unit 4, the area on the right side of the finger 201 in the display unit 4 is further increased. Therefore, as shown in the composite image 106B shown in FIG. 17, if the enlarged image 161B generated by increasing the magnification rate with the increase in the area on the right side of the finger 201 is displayed on the display unit 4, the finger 201 The enlarged image can be displayed more easily by the slide.

  Note that the composite image 106C shown in FIG. 18 may be displayed with the finger 201 in the same position as in FIG. In the enlarged image 161C included in the composite image 106C, the name “OO-chan” is displayed as information on the subject having the enlarged face. Information on the subject to be displayed here may be stored in advance in the face information storage unit 72 together with the face information. By displaying such a composite image 106C, the added value of the enlarged image itself can be increased, and more attractive and enjoyable image reproduction can be realized. In addition, if the identification information of the subject is stored together with the face information, a photographed image can be searched quickly.

  So far, the case where the enlarged image of the face of the person detected by the face detection unit 31 is generated has been described. However, when the user touches a place other than the face with a finger, the place may be enlarged and displayed. Good.
