Description

  The present invention relates to an imaging apparatus having a function of controlling display means for displaying a captured image.

  The number of pixels of an image sensor used in an electronic camera such as a digital camera in recent years is a size exceeding several million to over 10 million pixels. On the other hand, the number of pixels of a liquid crystal monitor which is a display device provided in an electronic camera is only several hundred thousand pixels.

  Thus, when shooting with manual focus while looking at a liquid crystal monitor with a small number of pixels, the focus state cannot be sufficiently confirmed due to the small number of pixels on the liquid crystal monitor. For this reason, it may be found that the image is not in focus only after the captured image is displayed on a personal computer or printed with a printer.

In view of the above points, Patent Document 1 discloses the following countermeasures. When manual focusing is performed while looking at the electronic viewfinder, the captured image is displayed on the screen, and at the same time, the image portion corresponding to the focus area is enlarged and displayed.

  The best mode for carrying out the present invention is as shown in the following examples.

  Next, the manual focus (MF) assist function in the first embodiment will be described with reference to FIG. It should be noted that the numerical values such as the sensor, image size, and magnification shown below are merely examples, and are not limited thereto.

  The optical signal incident through the lens 101 is converted into an electrical signal by the image sensor 105 having a size of 1600 × 1200 pixels while being appropriately exposed by the aperture 103. Then, it is thinned out in the vertical direction and read out at a size of 1600 × 300. Thereafter, the A / D circuit 106 converts the analog signal into a digital signal, and the signal processing circuit 107 performs an interpolation process, a color conversion process, and the like to convert it into a luminance color difference signal. The size after image processing is 1600 × 300.

  Image data from the signal processing circuit 107 is sent to the scaling circuit 108 and the clipping circuit 116. In the scaling circuit 108, the image data is reduced so that the image data becomes 640 × 240 and is sent to the memory control circuit 118. The image data at this time corresponds to the entire image 301 shown in FIG.

  At the same time, an assist display area image 302 shown in FIG. 3B is generated by the following process. In the cutout circuit 116, an assist display area (focus area) for clearly displaying the focal position is cut out from the image data at a size of 160 × 60. The extracted image data of the assist display area is sent to the scaling circuit 127 or temporarily stored in the DRAM 123 via the memory control circuit 118. Then, it is sent again to the super-resolution circuit 117 via the memory control circuit 118.

  When the image data is sent to the scaling circuit 127, the size of the image data is 320 × 120 that is doubled horizontally and vertically, and is the size of 1/4 of the entire image 301, and is shown in FIG. A later assist display area image 302 is obtained. Then, it is sent to the memory control circuit 118 and temporarily stored in the DRAM 123.

  On the other hand, when the data is sent from the clipping circuit 116 to the super-resolution circuit 117 via the memory control circuit 118 and the DRAM 123, the super-resolution processing is performed using the image data in the assist display area of four frames or more, and the horizontal and vertical directions are applied. The result is 320 × 120 multiplied by 2. Then, the super-resolution assist display area image 302 shown in FIG. 3B is obtained, sent to the memory control circuit 118, and temporarily stored in the DRAM 123.

  Here, an example of super-resolution processing in the super-resolution circuit 117 will be described with reference to FIG.

  In the cutout circuit 116 of FIG. 1, four frames of image 1, image 2, image 3, and image 4, which are cut out to a size of 160 × 60 shown in FIG. Each is temporarily stored in the DRAM 123. First, image 1 and image 2 are read from the DRAM 123 to the super-resolution circuit 117 via the memory control circuit 118. Then, in the super-resolution circuit 117, the shift amount of the image 2 with respect to the image 1 is obtained. FIG. 5 shows a state where the image 1 and the image 2 are shifted. Assume that A (A1 to A4) in (A-1) in FIG. 5 is an image 1, and B (B1 to B4) in (B-1) is an image 2.

  As shown in (A-2) and (B-2) of FIG. 5, black data, that is, a zero-valued pixel K, is inserted one by one before and after the A pixel and the B pixel. When the A and B pixels are shifted by a shift amount H in the horizontal direction and a shift amount V in the vertical direction, when the two are overlapped, the state shown in FIG. 5 (AB-3) is obtained. The shift amounts H and V are numerical values of 1 or less. The value of the pixel K is calculated from the pixel B as follows.

  As an example 1, when the shift amount H = 0.5 and the shift amount V = 0.5, the pixel data of K3, K6, K9, and K12 are the pixel data of B1 to B4, such as K3 = B1. Can be represented. At this time, the values of K1 and K2, K4 and K5, K7 and K8, K10 and K11 are not calculated.

  As an example 2, when the shift amount H = 0.3 and the shift amount V = 0, the right side of the A pixel, that is, the values of K1, K4, K7, and K10 are calculated by the following equations, respectively.

K1 = (0.5 + H) × B1 + (0.5−H) × B2
= 0.8 × B1 + 0.2 × B2
At this time, the values of K2 and K3, K5 and K6, K8 and K9, K11 and K12 are not calculated.

  As an example 3, when the deviation amount H = 0.3 and the deviation amount V = 0.3, the values of K3, K6, K9, and K12 are calculated by the following equations, respectively.

K3 = (0.5 + V) × {(0.5 + H) × B1 + (0.5−H) × B2} +
(0.5−V) × {(0.5 + H) × B3 + (0.5−H) × B4}
= 0.8 ^ 2 x B1 + 0.8 x 0.2 x (B2 + B3) + 0.2 ^ 2 x B4
At this time, the values of K1 and K2, K4 and K5, K7 and K8, K10 and K11 are not calculated.

  Using the above method, the composite image 1 is generated from the image 1 and the image 2 in FIG. At this time, the size of the composite image 1 is 320 × 120. The composite image 1 is temporarily stored in the DRAM 123.

  Next, the composite image 1 and the image 3 are read from the DRAM 123. At this time, it is assumed that A in (A-1) and (B-1) in FIG. 5 is a composite image 1 and B is an image 3. In (A-2), one pixel is calculated from K1 to K3. Suppose that it is in a state. The composite image 1 has twice as many pixels as the image 3, but the image 3 also includes black data pixel by pixel before and after the B pixel, as shown in FIG. 5B-2. Calculation is performed in the same manner as described above based on the pixel data of the image 3 at the position of the remaining pixel K of the composite image 1. Depending on the shift amount of the image 3, when the position of the pixel B is close to the pixel A or close to the position of the pixel K calculated when generating the composite image 1, the pixel data calculated from the pixel B and Normalize by adding existing pixel data. For this reason, the remaining pixels K cannot be filled. The composite image 2 generated in this way is temporarily stored in the DRAM 123.

  Next, the synthesized image 2 and the image 4 are read from the DRAM 123 and synthesized by the same method as described above to generate the super-resolution image 1. A pixel K for which pixel data could not be calculated in the super-resolution image 1 is interpolated using pixels around the super-resolution image 1. Super-resolution image 1 is temporarily stored in DRAM 123. The size of the super-resolution image 1 is 320 × 120 as shown in FIG.

  In order to generate a super-resolution image 2 (not shown) that is the next frame of the super-resolution image 1, the reference image is set as the image 2, the amount of deviation between the image 2 and the image 3, and the image 2 and the image The amount of deviation 4 and the amount of deviation between images 2 and 5 are obtained, and a super-resolution image 2 of 320 × 120 is generated by similarly performing the super-resolution processing. Thereafter, the same super-resolution processing is continuously performed.

  Note that when the super-resolution image 2 is generated, the super-resolution processing is newly performed on the images 2 to 5 without using the data of the super-resolution image 1. This is because if the data of the super-resolution image 1 is used, old data remains, so that if it continues to be displayed on an electronic viewfinder (hereinafter EVF), it will appear as an afterimage.

  The entire image 301 scaled to 640 × 240 temporarily stored in the DRAM 123 of FIG. 1 and the assist display area image 302 having a size of 320 × 120 by super-resolution processing or enlargement processing are stored in a memory control circuit. The data is read out to the reproduction circuit 121 via 118.

  The camera shake detection is performed in the motion vector detection circuit 110, and the previous and next frames are compared. If the motion vectors of the divided blocks of the image are almost equal as shown in FIG. 7A, it is determined that camera shake has occurred. Is done. Further, as shown in FIG. 7B, it is detected from the magnitude of the motion vector how many pixels the subject has moved within the effective pixel 601 due to camera shake. This detection result is sent to the reproduction circuit 121 and displayed on the LCD 122 having a display capability of about 640 × 240. For this purpose, the subject is displayed at the same position in the LCD display region 602 by moving the position of the readout start pixel 603 of the entire image 301 by the pixel based on the detection result.

  Further, by replacing the middle of the entire image 301 with the assist display area image 302, the LCD 122 displays the super-resolution image or the enlarged image on the entire image 301 as shown in FIG. The super-resolution image or the enlarged image is twice as large as the entire image 301, and camera shake occurs. Therefore, in the reproduction circuit 121, the position of the readout start pixel 603 of the super-resolution image or the enlarged image shown in FIG.

  At this time, when the release button is pressed, the data of the effective pixel 1600 × 1200 is read out in the image sensor 105. Then, desired image processing is performed in the signal processing circuit 107 and the scaling circuit 108 and temporarily recorded in the DRAM 123 via the memory control circuit 118. Thereafter, the captured image is read from the DRAM 123 to the compression / decompression circuit 119, JPEG-compressed by the compression / decompression circuit 119, and recorded on the memory card 120.

  Next, operations of main parts in the first embodiment will be described with reference to the flowchart of FIG.

  When the camera is activated in step 201, first, in step 202, it is determined whether or not it is set to perform shooting with manual focus (MF). If it is manual focus, the routine proceeds to step 203, where it is determined whether or not the manual focus (MF) assist function is ON. As a result, if it is ON, the process proceeds to step 204, and the focus state detection circuit 109 integrates the focus evaluation value for each divided frame 702 in FIG. Then, the cutout circuit 116 cuts out with the size of 160 × 60 using the division ratio with the highest focus evaluation value as the assist display area. The division frame for detecting the focus evaluation value corresponding to the contrast of the image is preferably about the same size as the cutout size.

  Returning to FIG. 2, in the next step 205, the focus state detection circuit 109 of FIG. 1 is set in advance as a determination level as to whether or not the focus evaluation value of the image in the assist display area is focused to some extent. Compare with the threshold value. As a result, if the threshold value is exceeded, the process proceeds to step 216. As described above, when the focus evaluation value is equal to or larger than the threshold value, the motion vector detection circuit 110 detects the motion of the subject in step 206. Then, as shown in FIG. 9, when the magnitude and direction of the motion vector are partially different, it is determined that the subject is moving. If the subject is stationary or the movement is small, the process proceeds to step 206, and the super-resolution circuit 117 superimposes the assist display area image that has been cut out to a size of 160 × 60 by the cut-out circuit 116 in FIG. Then, a 320 × 120 super-resolution image as shown in FIG.

  In step 205, it is determined that the focus evaluation value is equal to or greater than the threshold value. In the next step 216, if the subject is moving significantly, the process proceeds to step 207. In step 207, the image of the assist display area cut out by the cutout circuit 116 to a size of 160 × 60 is enlarged by the scaling circuit 127 so as to have a size of 320 × 120. Then, an enlarged image as shown in FIG. 3B is generated as the assist display area image 302.

  If it is determined in step 205 that the focus evaluation value is less than the threshold value, the process proceeds to step 207, where the cutout circuit 116 performs cutout processing to a size of 160 × 60. Then, an image of the assist display area is generated, and enlargement processing is performed in the scaling circuit 127 so as to have a size of 320 × 120, and an enlarged image as shown in FIG. 3B is generated as the assist display area image 302.

  In steps 206 and 207, the super-resolution image or the enlarged image is temporarily stored in the DRAM 123 via the memory control circuit 118. At the same time, the entire image 301 of FIG. 3A scaled to a size of 640 × 240 in the scaling circuit 108 is temporarily stored in the DRAM 123 via the memory control circuit 118. The reproduction circuit 121 reads the entire image 301 and the super-resolution image or enlarged image via the memory control circuit 118, and replaces the middle of the entire image 301 with the assist display area image 302 in the reproduction circuit 121. Thereby, on the LCD 122, as shown in FIG. 3C, the super-resolution image or the enlarged image is displayed so as to overlap the entire image 301.

  By performing the switching as in step 205 above, when the focus is gradually adjusted from the out-of-focus state, the image in the assist display area is changed from an enlargement process in which normal pixels become coarse to a super-resolution process with good resolution. At the moment of switching, it becomes easy to recognize the in-focus state.

  In addition, when super-resolution processing is performed on the image in the assist display area, manual focusing can be performed with a better resolution than when the enlargement processing is performed, and thus focusing becomes easier.

  Returning to FIG. 2 again, in step 208, when the display position of the assist display area in step 204 is not the focus position desired by the user, the user operates the switch 112 such as the cross key in FIG. Thus, the assist display area can be moved and changed. The movement range of the focus position at this time will be described with reference to FIG.

  As shown in FIG. 6A, the effective pixels are effective up to the top, bottom, left and right ends. When the frame portion shown in the lower left of the entire image in FIG. 6A is an area to be focused (focus area), this area is cut out as an assist display area, and super-resolution processing is performed.

  In FIG. 6B, frame 1, frame 2 and frame 3 which are assist display areas are adjacent frames shifted by time t. Super-resolution processing is performed on the composition of frame 1 using frame 2 and frame 3 with frame 1 as a reference. A cutout area 501 indicated by a black double frame indicates an area cut out by the cutout circuit 116. A super-resolution area 502 indicated by a dotted frame indicates an area necessary for performing the super-resolution processing.

  Frame 2 shows a case where the camera shakes in the upper right direction with respect to frame 1 and the cutout area 501 is shifted to the upper right, and image data of the left and lower areas in the composition of frame 1 indicated by the missing part 1 Is missing.

  Frame 3 shows the case where the camera shakes in the lower left direction with respect to frame 1 and the cutout area 501 is shifted to the lower left. Images of the upper and right areas in the composition of frame 1 indicated by the missing part 2 Data is missing. For this reason, the pixel data of the missing portion 1 and the missing portion 2 can be supplemented by copying pixel data of the same region from another frame such as the frame 1 to compensate for the edge portion of the image. It is also effective to make the size to be cut out a region slightly larger than 160 × 60.

  Returning to FIG. 2 again, in the next step 209, the user performs manual focus while viewing the LCD 122 displayed in EVF in the state shown in FIG. Then, in the next step 211, photographing is performed by the user. After the completion of the photographing in step 211, the state returns to the state immediately after the activation of the camera in step 201.

  If it is determined in step 202 that auto focus is set instead of manual focus, the process proceeds to step 210, where an automatic focusing operation is performed. In the next step 211, shooting is performed by the user.

  In step 203, when the MF assist is set to OFF, the EVF display on the LCD 122 is displayed as an entire image 301 as shown in FIG. 3A. In step 209, the user performs manual focus, In the next step 211, photographing is performed by the user.

  According to the first embodiment described above, when performing manual focus while viewing the EVF display displayed on the LCD 122 screen, the super-resolution processing is performed on the assist display area (focus area) of the captured image. Thereby, a small subject such as less than one pixel can be clearly displayed, and it can be easily determined whether or not the subject is in focus.

  FIG. 10 is a diagram showing a system configuration of an imaging apparatus according to the second embodiment of the present invention. The same parts as those in FIG.

  In the first embodiment, camera shake correction is performed by shifting the LCD display start position in the reproduction circuit 121. On the other hand, in the second embodiment of the present invention, a configuration in which camera shake correction is performed immediately after the signal processing circuit 107 and before the super-resolution processing will be described.

  An optical signal incident through the lens 101 is converted into an electrical signal by the image sensor 105 having a size of 1600 × 1200 pixels while being appropriately exposed by the diaphragm 103. Then, it is thinned out in the vertical direction and read out at a size of 1600 × 300. Then, the A / D circuit 106 converts the analog signal into a digital signal, and the signal processing circuit 107 performs interpolation processing, color conversion processing, and the like. The size after image processing is 1600 × 300.

  The image data subjected to the image processing is sent from the signal processing circuit 107 to the camera shake correction circuit 126. An example of a camera shake detection method performed in the camera shake correction circuit 126 will be described.

  In the camera shake correction circuit 126, a frame at a certain time is placed in the frame memory 125, and image matching is performed with the next frame. Then, the start pixel for placing the next frame in the frame memory 125 is moved according to the detected shift amount. The amount of movement of the start pixel placed in the frame memory 125 is in units of pixels, and the amount of deviation between the previous and subsequent frames after camera shake correction is less than one pixel. Image data that has been subjected to camera shake correction from the camera shake correction circuit 126 is sent to the scaling circuit 108 and the clipping circuit 116.

  The scaling circuit 108 reduces the image data to a size of 640 × 240, and temporarily stores the reduced image data in the DRAM via the memory control circuit 118. The image data at this time corresponds to the entire image 301 shown in FIG. At the same time, an assist display area image 302 shown in FIG. 3B is generated by the following process.

  In the cutout circuit 116, an assist display area for clearly displaying the focal position is cut out from the image data at a size of 160 × 60. The extracted image data of the assist display area is sent to the scaling circuit 127 or temporarily stored in the DRAM 123 via the memory control circuit 118. Then, it is sent again to the super-resolution circuit 117 via the memory control circuit 118.

  When the image data is sent from the clipping circuit 116 to the scaling circuit 127, the size of the image data is 320 × 120 that is doubled horizontally and vertically, and is ¼ the size of the entire image 301 (b). The enlarged assist display area image 302 shown in FIG. 2 is sent to the memory control circuit 118 and temporarily stored in the DRAM 123.

  On the other hand, when the image is sent from the clipping circuit 116 to the super-resolution circuit 117, the super-resolution processing is performed using the image data of the assist display area of four frames or more in which the shift amount in the preceding and following frames is less than one pixel. . The size is 320 × 120, which is doubled horizontally and vertically, and becomes the super-resolved assist display area image 302 shown in FIG. 3B, which is sent to the memory control circuit 118 and temporarily stored in the DRAM 123.

  The entire image 301 scaled to 640 × 240 temporarily stored in the DRAM 123 and the assist display area image 302 having a size of 320 × 120 by super-resolution processing or enlargement processing are passed through the memory control circuit 118. And read to the reproduction circuit 121. In the reproduction circuit 121, the middle of the whole image 301 is replaced with the assist display area image 302, whereby an assist display is displayed on the whole image 301 as shown in FIG. 3C on the LCD 122 having a display capability of about 640 × 240. The area images 302 are displayed in an overlapping manner.

  At this time, when the release button is pressed, the data of the effective pixel 1600 × 1200 is read out by the image sensor 105, and desired image processing is performed in the signal processing circuit 107 and the scaling circuit 108. The image data that has been subjected to camera shake correction by the camera shake correction circuit 126 is temporarily recorded in the DRAM 123 via the memory control circuit 118, read out from the DRAM 123 to the compression / decompression circuit 119, JPEG-compressed by the compression / decompression circuit 119, and the memory card. 120.

  According to the second embodiment described above, when performing manual focus while watching the EVF display displayed on the LCD 122 screen, the assist display area of the captured image is subjected to super-resolution processing. Thereby, a small subject such as less than one pixel can be clearly displayed, and it can be easily determined whether or not the subject is in focus.

  In the first and second embodiments described above, a place or subject with sufficient brightness for photographing is photographed, and a method of normalizing the number of frames when a plurality of frames are combined by super-resolution processing. Is shown. However, in the case of shooting where the subject or the place is dark, when a plurality of frames are combined by super-resolution processing, EVF display is performed on the LCD in a state where the display gain is increased without being normalized. You may do it. As a result, a dark subject becomes bright and manual focusing can be easily performed.
