Abstract

PROBLEM TO BE SOLVED: To capture a "miniaturized photograph" image of a digital camera, and obtain a distinct effect.SOLUTION: A system control unit 29 reads out a set content at power-on, and determines "user setting" or "automatic setting" during a "miniaturized photographing" process. During the "user setting," a shading-off process is applied in a set shade-off region and monitoring is executed, and, upon a shade-off region change request, a setting screen is entered into, in which monitoring is executed in a changed shade-off region. Further, a subject detection mode is checked, and, during a face detection mode, a face is detected from within the angle of view and subjected to focal processing, and then, upon moving of the face to within the shade-off region, detection is aborted. During the "automatic setting", monitoring is executed centering an AF region subjected to AF processing by a first release as a center of a region of interest and its periphery as a shade-off region. Upon pressing of a second release, a main image is transferred from a CCD/CMOS unit 20 to an image processing unit 25 and expanded into a memory unit 26 by shutter control from a monitoring process, and regions other than the subject being in focus are shaded off, whereby an effect is obtained.

Description

  The present invention is applicable to portable electronic devices such as a mobile phone, a personal digital assistant (PDA), and a toy having an image pickup means, and particularly relates to an image pickup apparatus and an image pickup method used for an image processing mechanism of a digital camera. It is.

  In recent years, digital cameras have exploded in popularity. A feature unique to digital cameras is that photographs can be processed freely during and after imaging. As one of such processing techniques, a so-called “miniature photography” technique is known in which a model is processed as if it was taken from a short distance in a landscape photograph taken normally. Many of these techniques are performed by using retouching software for image editing and following a few steps, but packed “miniature photography” to easily implement those know-how. The processing software has already been released.

As a method using actual retouching software,
1. By increasing the contrast and saturation of a photo, the image has a strong contrast and clear color (improves the state of the hazy image often seen in landscape photos).
2. For a photo with a deep depth of field, that is, a wide focus distance range, set a shallow depth of field, that is, a narrow focus range (so that areas other than the main subject are not in focus). Blur).

  By such a method, anyone can easily perform “miniature photography” processing on the captured photograph.

  Patent Documents 1 and 2 describe a technique for determining an automatically focused area and performing a process of blurring the area other than the automatically focused area to obtain an image with a blurred background such as a portrait. . In Patent Documents 1 and 2, although the blurring process is performed, it is not related to “miniature photography”, and an area to be blurred cannot be specified.

  However, it is troublesome and troublesome to perform processing (image processing) using the retouching software on a PC (personal computer).

  In addition, when performing “miniature photography” by processing the captured image, the focused area cannot be changed because the focused area is determined in the captured image. .

  In other words, in the processing software when performing "miniature photography", the user sets the attention area that he wants to look like a miniature, and blurs the area other than the set attention area so that it is not in focus, I tried to get a miniature photo.

  However, in the captured image, if the in-focus area and the attention area set by the user are different, the area that you want to look like a miniature in the image is not in focus even after performing “miniature photography” There was a problem that the effect of “miniature photography” could not be obtained clearly.

  The present invention solves the above-described problems of the prior art, and can automatically capture a “miniature photograph” image at the time of imaging with a digital camera, thereby eliminating the trouble of processing later. It is an object of the present invention to provide an imaging apparatus and an imaging method that can easily perform the process of “miniature photography” and can clearly obtain the effect.

In order to achieve the above object, an imaging apparatus according to claim 1 according to the present invention includes: an imaging unit that images a subject and outputs image data;
Display means for displaying a display image based on the image data;
Blur processing means for performing blur processing by image processing on at least a part of the display image displayed on the display means;
In the display image, by specifying at least one of a first region where the blur processing unit performs blur processing or a second region where the blur processing is not performed, the blur processing unit performs blur processing. An area specifying means for specifying one area;
With
The second region is rectangular;
In the monitoring state when taking images of miniature photographs,
The second area is movable within the display area of the display means while maintaining the shape and size specified by the area specifying means,
The blur processing means performs blur processing on the first area based on the movement of the second area,
An area that at least partially overlaps the area of the image data corresponding to the second area is set as an autofocus area.

  According to the present invention, it is possible to prevent blurring processing on an autofocused area or to automatically focus a blur processing area outside the attention area, and to include a focusing area. There is an effect that it is possible to save the troublesome work for “miniature photography” processing by automatically setting a region not subjected to blurring processing as a region of interest.

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

  FIG. 1 is a block diagram showing a schematic configuration of an imaging apparatus according to Embodiment 1 of the present invention. 2 is an external view of the image pickup apparatus (digital camera) according to the first embodiment as viewed from above, in which (a) shows a retracted state of the lens barrel unit, and (b) shows an extended state of the lens barrel unit. . 3 is an external view of the image pickup apparatus (digital camera) viewed from the front, that is, from the subject side, and FIG. 4 is an external view of the image pickup apparatus (digital camera) viewed from the rear, that is, from the photographer side.

  As shown in FIG. 1, the imaging device (digital camera 1) includes a zoom lens, a focus lens, a mechanical shutter, and a diaphragm as an imaging lens unit in the lens barrel unit 2. A zoom control unit 21 for realizing a zoom function, a focus control unit 22 having a function for focusing on a subject, an aperture control unit for controlling the brightness of the subject, and an aperture / shutter control unit 23 for performing shutter control, respectively. The lens barrel unit 2 is provided with a lens barrel storing / feeding control unit 24 for feeding or storing these lens barrel units 2 at startup.

  The zoom lens and the focus lens are operated by a motor (not shown). 2A shows an external view of the state in which the lens barrel unit 2 is housed, and FIG. 2B shows an external view when the lens barrel unit is extended. 2A and 2B are views of the digital camera 1 as viewed from above. A release shutter 4, a mode dial 5, and a power switch 3 are disposed at the top.

  The mode dial 5 has an imaging mode, a playback mode for displaying captured images, a setup mode for making various settings, a portrait mode for capturing people, a portrait mode for capturing night scenes, and the like. Provided to the user, the user switches each mode with the mode dial 5 described above.

  In the first embodiment, a “miniature photography” mode (an imaging mode in which a miniature is photographed in a normal photograph is processed and recorded) may be similarly assigned to the mode dial 5. For example, when the dial is set as the imaging mode, the lens barrel unit 2 is extended to the imaging possible position to enter the monitoring state.

  In the monitoring state, the user who takes an image is viewing the subject in real time on the display unit (LCD monitor) 18 of the external view shown in FIG. In this state, the release shutter 4 is in a released state, and an image received through the zoom lens and the focus lens is converted into an electrical signal from a CCD or CMOS CCD / CMOS unit 20 as a light receiving element, and digitally Is transferred to the image processing unit 25 as image data. The image is displayed on the display unit (LCD monitor) 18 in real time. Normally, a small image of 30 frames per second with a pixel number of 640 × 480 is transferred and displayed on the display unit (LCD monitor) 18 so that the user can confirm the subject in real time and wait for the opportunity to press the release shutter 4. .

  The release shutter 4 is often in two stages, and a state where the button is half-pressed is defined as a first release, and a state where the button is fully pressed (pressed, pressed) is defined as a second release. An autofocus (AF: automatic focusing) process is performed by the first release in which the release shutter 4 is half-pressed. That is, the focus is locked. This will be described below.

  When the release shutter 4 is half-pressed (first release), an AF evaluation value indicating the degree of focus on the screen and an AE indicating the exposure state are obtained from the YUV signal fetched from the CCD / CMOS unit 20 into the image processing unit 25. An evaluation value is calculated. The AF evaluation value data is read as feature data to the system control unit 29 and used for automatic focusing (AF) processing. When the integral value is in a focused state, the edge portion of the subject is clear, so that the high frequency component is the highest. By utilizing this, at the time of focus detection operation by AF processing, an AF evaluation value at each focus lens position is acquired, and a point (peak position) at which the maximum is obtained is detected.

  Also, taking into account the fact that there are multiple points that become maximal, if there are multiple points, the magnitude of the evaluation value of the peak position, the degree of decrease or increase of the evaluation value in the vicinity, and the degree of increase or decrease are judged, the most reliable point AF processing is executed with the in-focus position.

  The AF evaluation value can be calculated from a specific range in the digital RGB signal. The center frame in the display unit 18 is an AF area in the digital camera 1. As shown in FIG. 5, it is assumed that the horizontal 60% and vertical 50% in the RGB signal.

  Next, although not shown in the figure, the AE evaluation value uses luminance data obtained by dividing the YUV signal into several regions (horizontal 16 × vertical 16 in this digital camera 1) and measuring the region. A pixel that exceeds a predetermined threshold with respect to pixels in each region is determined as a target pixel, and the luminance value is added and multiplied by the number of target pixels. An appropriate exposure amount is calculated based on the luminance distribution of each region, and correction is performed for capturing the next frame.

  The basic control method of the automatic focusing (AF) process is executed according to the flowchart of FIG. The focus of the predetermined pulse amount is moved (S1), and then an AF evaluation value is acquired based on the AF area data (S2). Peak detection is confirmed from the results obtained by smooth differentiation (S3), peak detection processing (S4), etc. (S5). If a peak is detected (Yes in processing S5), the peak is determined based on the result. The position is calculated (S9), and the process proceeds to the end process. If no peak is detected (No in process S5), the end position is confirmed (S6) and until the end position is reached (No in process S6). ) The focus drive and AF evaluation value acquisition are repeated again, and the process ends when a peak is detected.

  Further, when the focus cannot be detected by moving the focus to the end position (No in S6), that is, when the focus cannot be adjusted from “nearest” to “infinite”, a peak area selection process is performed (S7). As an example, when the evaluation value is obtained from infinity on the closest side, it is determined that the subject is too close, and “NG” is displayed on the display unit as “NG” (S8). Based on the result of “NG”, the peak position (none) is calculated (S9), and the process proceeds to the end process.

  As the above-described peak detection method, smooth differentiation is often used, but when the AF evaluation value in the in-focus area changes from 0 to a negative value, the peak of the AF evaluation value is detected, ie, recognized (FIG. 7). reference).

  As for AF processing, there is a one-shot autofocus method that focuses on the first release described above, and in recent years, if the face of the subject is detected and focused on the detected face, There is also a method of performing so-called moving object tracking autofocus that keeps focusing on the face at the moved position even if the camera moves. This is referred to as a so-called subject detection mode, and aims to keep focusing on a moving object.

  FIGS. 8A to 8C show examples of multi-autofocus. In the example shown in FIG. 5, the AF area is one area. However, in this multi-autofocus processing example, each AF area 20b is divided into 15 AF areas 20b as shown in FIG. 8A. A peak is detected. If two or more adjacent areas detect peaks, they are considered to be in focus, and in order to notify the user that the focus has been achieved, a display indicated by a one-dot chain line in FIG. The frame 18a is displayed, and a sound for notifying that the focus has been achieved is emitted from the speaker.

  A normal digital camera supplies power from a dedicated battery or AA batteries, and supplies an appropriate voltage to each block from the power supply circuit unit 16 shown in FIG. 1 such as a DC / DC converter. The image processing unit 25 performs various image processes on the digital image data described above. When the second release is pressed (the release shutter 4 is fully pressed), for example, if the main image is a 10M CCD, a digital image YUV signal having a 10M image size is transferred to the image processing unit 25. .

  Furthermore, it has an image conversion function for converting an image format for conversion to the YUV format (Y: luminance data, UV: color difference data). It has a compression / decompression function for compressing YUV data by a compression system compliant with the JPEG system, or decompressing a compressed image, and an image processing function for blurring a designated area.

  In addition, memory units (volatile and nonvolatile) 25 and 27 such as SDRAM and flash memory, image processing unit 25, external memory card I / F unit 17, system control unit 29, USB communication unit 12, and display unit 18 Interconnected by a system bus 30.

  The compressed image data is added to the JPEG data header with the shooting conditions and the model name of the digital camera so that the file format Exif conforms to the digital camera file format, and the memory portion (volatile: SDRAM) as a captured JPEG file 26 is temporarily stored. A plurality of types of external memory card I / F unit 17 such as CompactFlash (registered trademark) and SD card have been released. The external memory card I / F unit 17 is detachably provided and stores the above-described JPEG file.

  FIGS. 9 and 10 are flowcharts showing the operation of the imaging apparatus according to the first embodiment, which will be described according to FIGS. 9 and 10 with reference to FIGS.

  As shown in FIG. 9, when the power of the digital camera 1 is turned on (S11), first, an operation program is activated in the system control unit 29, and the setting contents set in the setup process are read (S12). The setting contents are stored in the memory unit (non-volatile) 27, and the contents are not lost even when the power is turned off. In the first embodiment, for example, the user can select either “blur area is set by the user” or “blur area is automatically set based on the AF processing result” as setting contents for performing “miniature photography”. It is determined whether or not the setting has been made (S13). In the case of “automatic setting” in the process S13, the process proceeds to the flowchart shown in FIG.

  Further, in the setup process, the user makes settings while viewing the display unit (LCD monitor) 18 using the MENU button 15a and the up / down / left / right buttons 14b to 14e shown in FIG. The contents set here are stored in the memory unit (non-volatile) 27.

  Next, in the case of “user setting” in the process S13 of FIG. 9, as shown in the flowchart of FIG. 10, it is determined whether or not the mode is the “miniature photography” mode (hereinafter referred to as the miniature mode) (S14). In this case, it can be determined by setting the mode dial 5. If the mode is not the miniature mode (No in step S14), the normal imaging monitoring process is performed (S15). If the mode is the miniature mode (Yes in step S14), the blurring process is performed based on the blur area setting set by the user. And monitoring (S16). When the first release is pressed, AF processing is executed in the AF area.

  A setting example of the user's blur region is shown in FIG. An attention area 18c to be focused without blurring is set at the lower left, an intermediate area 18d for weak blurring to slightly blur the periphery, and a blurring area 18b for other blurring. In FIG. 11B, a rectangular attention area 18c for focusing processing, an intermediate area 18d for faint blurring, and a remaining blurring area 18b for blurring are set.

  When blurring an image during monitoring, an OSD (on-screen display) may be displayed on the display unit 18 so that the user can easily understand. Specifically, the attention area 18c not to be blurred is a plane with a transmittance of 100%, and the blurring area 18b has a transmittance of 50%, so that the user can set the image data without actually blurring the image data to be monitored. It is possible to take an image while recognizing the blurred region 18b.

  If there is a user request to change the blur area 18b during monitoring (S17), if this is confirmed (Yes in process S17), the screen shifts to a setting screen for the blur area 18b (S18). When the user presses the display button 15d shown in FIG. 4, the trigger for this request shifts to the attention area / blurring area setting screen as shown in FIGS. 12 (a) to 12 (d). 12A and 12B, the attention area 18c is moved by moving the attention area 18c up and down with the up and down keys (pressing the upper button 14b and the lower button 14c). The width of the attention area 18c is operated with the left and right keys (pressing the left / strobe button 14e and the right / macro button 14d). In the case of FIGS. 12C and 12D, it is a circular attention area 18c. In this case, the attention area 18c is moved with the up / down / left / right keys (buttons 14b, c, d, e), the attention area 18c is enlarged with the zoom switch (WIDE) 13a, and the attention area 18c is enlarged with the zoom switch (TELE) 13b. Make it smaller.

  In this process S18, when the area is changed, for example, the process returns to the process S16, and the change is performed and the blurring process is performed based on the area, and monitoring is performed.

  Thus, the user can set the attention area 18c and the blur area 18b. At this time, when the first release is pressed, AF processing is performed in accordance with the blur area 18b in which the user has changed the setting of the AF area. An example of the relationship between the blur area 18b and the AF area 20b is shown in FIGS. In the case of FIG. 13B, the attention area 18c is narrow and the center is set upward. In this case, the AF area 20b is similarly narrow, and the range of the area is narrowed from the center to the top. Since the AF evaluation data is also narrower than the normal area, the AF process is fast, and the focus lens is moved to focus on the subject in the AF area 20b.

  Further, it is confirmed whether the digital camera 1 is in the subject detection mode (S19). Here, in the case of the subject detection mode at the time of monitoring (Yes in processing S19), for example, in the case of the face detection mode, it is detected whether there is a face from the monitoring image at the time of monitoring. Once a face is detected, focus processing is performed during monitoring according to the face. In this case, the face detection area is usually a wide range as in AF, but when the blur area 18b is set as shown in FIG. 13A, the area outside the area (the attention area 18c) is the center. Therefore, the detection speed is also increased. If the detected face moves into the blur area 18b, the detection is stopped (S20).

  Further, the exposure control is performed by the aperture / shutter control unit 23 shown in FIG. 1 in the same manner as the focusing process, but the exposure is controlled around the region of interest. It is confirmed whether or not the release shutter (second release) has been pressed (S21). If the second release is not pressed (No in step S21), the monitoring process is repeated from step S16. When the second release is pressed (Yes in process S21), the AF process of the AF area, the exposure process of the exposure area, the process of the blur area are limited, and the like is prepared for imaging (S22). By performing shutter control, the main image is transferred from the CCD / CMOS unit 20 to the image processing unit 25 and developed in the memory unit 26 (S23). This is the first image. In addition, the developed first image is copied to another area of the memory unit 26 (S24). Let the duplicated image be the second image.

  The second image is subjected to blurring processing on a predetermined blurring area 18b set by the user (S25). The first and second images are each compressed, converted into an image file as a JPEG image, and stored in the SD card (S26).

  In the first embodiment, in the attention area set and changed in advance by the user, in order to focus on the subject, focusing processing is performed if a part of the focusing area is within the attention area, and focusing is performed if the focus area is outside the attention area. Since focus processing is not performed, useless focusing processing and exposure processing are not performed.

  FIG. 14 is a flowchart showing the operation of the image pickup apparatus according to the second embodiment of the present invention. The operation will be described with reference to FIGS. Here, in FIG. 14, the same reference numerals are given to the equivalent components corresponding to those described with reference to FIG.

  In the case of “automatic setting” in the process S13 shown in FIG. 9, it is determined whether or not the miniature mode is selected as shown in the flowchart of FIG. 14 (S14). In the miniature mode (Yes in process S14), the first release is pressed and the AF process is executed. The blur process is performed with the AF area as the center of interest and the surrounding area as the blur area. In this case, as understood by the user, the OSD display (attention area 18c) may be performed in a rectangular shape as shown in FIG. 8C during the first release. In the case of a circle, OSD display (attention area 18c) may be performed as shown in FIG.

  In the second embodiment, since the attention area / blurred area is automatically set, it is confirmed whether the subject detection mode is in the process S19 without performing the processes S16 to S18 for setting the blurred area shown in FIG. Done. In the case of the subject detection mode (Yes in process S19), instead of the process S20, monitoring is performed with the area detected by the subject subjected to AF processing as the center of the attention area and the surrounding area as a blur area (S30).

  When a face is detected in the subject detection mode, OSD display is performed during monitoring so that it can be seen that the face is detected by the display frame 18a indicated by a one-dot chain line as shown in FIG. In this case, as shown in FIG. 15B, the attention area 18c not to be blurred may be a plane display with a transmittance of 100%, and the blur area 18b may be an area display with a transmittance of 50%.

  Then, the AF processing in the automatically set attention area is as described above, and the processing when the second release is actually pressed (Yes in processing S21) and the image is captured is taken in the main image from the imaging device, This is the same as the description of the processing S22 to S26 in the flowchart of FIG.

  In addition, the attention area is automatically set according to the second embodiment, and the subject to be “miniature photography” can be changed to an arbitrary position within the angle of view without performing unnecessary focusing and exposure processing. Thus, troublesome work such as setting can be reduced.

  The imaging apparatus and the imaging method according to the present invention prevent blurring processing on an automatically focused area, or preventing unnecessary focusing on an area to be blurred outside the attention area. It is possible to save the troublesome work of “miniature photography” processing by automatically setting the area including the in-focus area as the attention area, and applied to electronic devices such as mobile phones, personal digital assistants (PDAs), and toys. It can be used for an image processing mechanism.
