Description

Side by side stereo image capturing method and monocular camera for same

The present invention relates to a three-dimensional stereoscopic imaging technique, and more particularly, to a method for capturing side by side stereo images with a camera employing a monocular lens and a monocular camera device for the same. will be.

It takes a lot of money and time to produce 3D stereoscopic images. In order to produce 3D stereoscopic images, a 3D camera and a program having a different configuration from a general 2D camera are required. 3D cameras are not only expensive because of the complicated structure of equipment such as mounting two lenses, but also more complicated than general cameras. Therefore, it was not easy for general users to make stereoscopic images.

The public usually has a camera mounted on a digital camera or smartphone. Most of these digital cameras and smartphones are single lens cameras employing only one lens, and the images taken are two-dimensional images. In particular, for small devices such as smartphones, what is required in the design is to reduce the size and number of components employed therein as much as possible. The design of employing two lenses to construct a 3-Dimensional (3D) camera in a smartphone is against this purpose. In addition, the adoption of two lenses is a factor in the rise in smartphone prices. However, if a monocular camera capable of capturing two-dimensional images without expensive photographing equipment or photographing technology can easily produce three-dimensional stereoscopic images, the production of three-dimensional stereoscopic images may increase rapidly.

There is an example where a technology of photographing a 3D stereoscopic image with a single camera is introduced. One method (Dong-Woo Lee, Kwan-Wook Lee, Man-Bae Kim, 'Creating 3D Image using Monocular Camera', Journal of Broadcast Engineering, Vol. 17, No. 1 pp17-25, 2012), is similar to a sequential shooting method. After taking a plurality of images manually or automatically while moving, select two images suitable for producing a stereoscopic image from the obtained image, and finally produce a stereoscopic image considering binocular disparity. In this method, when shooting with the camera in hand, camera shake occurs and stable shooting becomes difficult. Thus, a final stereoscopic image is produced through correction. However, even if it is possible to shoot a still image as a three-dimensional image by this method, it is almost necessary to go through image stabilization, it is questionable whether even a moving image can be recorded in real-time.

An object of the present invention is to provide a method for easily photographing a side by side stereo image by attaching a reflector to a monocular camera having only one lens and a camera therefor.

A reflector to be incident to the light source; And a reflector holder for holding the reflector to stand side by side in the axial direction of the lens and in a predetermined angular deviation range toward the front of the lens next to the camera module, with one side coupled to the camera body. The first image of the image sensor reflected by the reflector is incident on the lens and is incident on the first half of the image sensor, and directly enters the lens without passing through the reflector. And a second image formed in two and a half, wherein the signal processor executes a predetermined application program to perform a signal conversion process of inverting the left and right of the first image formed in the first half of the image sensor and converting the signal. Side by side the processed video signal of the first video and the original video signal of the second video ide) A monocular camera is provided for capturing a side by side stereo image, characterized in that a process of storing the stereo image as a stereo image is performed.

In the monocular camera, the reflector holder is coupled to the camera body in the form of a back support for holding and holding the back of the reflector, and the other side to hold and tighten one side of the camera body while one side is coupled to the back support. It includes a holding part.

The camera provides a menu for the user to select one of the 2D shooting mode and the 3D shooting mode, and the application program is configured to be automatically executed only when the 3D shooting mode is selected.

The application program converts a signal that the signal processor reverses left and right of the first image at a speed at which the signal processing unit can store side by side stereo video of at least 30 frames per second in the storage means. It is preferably configured to perform the process in real time.

The application program may include n vertical pixels V (i) of the image sensor (i = 1, 2, 3, ..., n) and m horizontal pixels H (j) (j = 1, 2, 3,..., M), pixels V (1), V (2), V (3),... Positioned in the first half of the image sensor. , The values of V (n / 2) are V (n / 2), V ((n / 2) -1),... And a signal conversion process of inverting the left and right sides of the first image by performing a process of changing the values of the V (2) and V (1) pixels to the columns of H (1) to H (m), respectively. do.

The reflector is preferably mounted within an angular deviation range of ± 5 ° from the axial direction of the lens.

In order for the reflected image to fill half of the rectangular image sensor, it is preferable that the reflecting mirror has a straight upper and lower edges.

The camera to which the present invention can be applied may be any electronic camera capable of executing an application program. For example, the camera may be a smartphone camera, wherein the camera body is a smartphone body and the camera module is a camera module mounted on the smartphone body.

The signal processor may be configured to display a virtual dividing line for dividing the display screen of the camera from side to side on the display screen of the camera in order to execute the application program so that the reflector is installed at the correct position. Do.

On the other hand, according to another aspect of the present invention for achieving the above object, one lens, an actuator for driving the lens, an image sensor for converting the light of the image passing through the lens into an electrical signal, the image sensor Taking a side-by-side stereo image using a monocular camera including a camera module having a signal processor which reads an image signal from an image signal and performs a predetermined process, and a driver for driving the actuator, and a camera body in which the camera module is installed. In this case, the reflecting mirror is installed in the form of standing up side by side in the axial direction and the predetermined angle deviation range of the lens toward the front of the lens next to the camera module, the image formed on the image sensor, Reflected and incident on the lens, the first half of the image sensor A first image and a second image that is incident directly to the lens without passing through the reflector and is formed on the remaining second half of the image sensor; And the signal processing unit executes a predetermined application program to perform a signal conversion process of inverting the left and right sides of the first image formed in the first half of the image sensor, and the image signal of the first image subjected to the signal conversion processing. And a step of storing the original video signal of the second video as a side by side stereo video in a storage means.

In the signal conversion process of inverting the left and right sides of the first image by the application program, the number of vertical pixels V (i) of the image sensor is n (i = 1, 2, 3, ..., n) and the horizontal pixels H (j). Is m (j = 1, 2, 3, ..., m), the pixels V (1), V (2), V (3),..., Located in the first half of the image sensor. , The values of V (n / 2) are V (n / 2), V ((n / 2) -1),... , V (2), V (1) may be performed by a method of changing the values of the pixels, respectively, from H (1) to H (m) for each column.

The side-by-side stereo image capturing method may further include automatically executing the application program only when the 3D capturing mode is selected by providing a user menu for selecting any one of a 2D capturing mode and a 3D capturing mode. It is preferable to provide.

The application program converts a signal that the signal processor reverses left and right of the first image at a speed at which the signal processing unit can store side by side stereo video of at least 30 frames per second in the storage means. It is desirable to be configured to perform the process in real time.

In order to help the reflector be installed at the correct position, the camera module may further include a step of displaying a virtual dividing line dividing the display screen of the camera from side to side on the display screen.

According to the present invention, by attaching a simple reflector to a smart phone or a small camera lens made of a conventional one, it is possible to enjoy the 3D stereoscopic image by restoring the left and right flipped images taken by reflecting through the reflector to their original state. Side by side stereo image can be taken.

Instead of using a stereo camera having two lenses, a monocular camera having only one lens can be used to capture 3D stereoscopic images, thereby significantly reducing the cost of capturing 3D images.

In particular, since it can be easily applied to a smartphone camera that most people have, it is expected that the generation of stereo image contents will be very active.

In addition, the user may select whether to photograph in a 3D image or a 2-Dimensional (2D) image. While the reflector is removable, it is also possible to select whether or not to run the program for restoring left and right flips. Since the installation of the reflector and the execution of the program for restoring the left and right flips are a matter of choice, the users should take their monocular camera and shoot 3D stereoscopic images only when necessary and 2D images when they are not necessary. There is also a convenience to choose from. That is, the monocular camera can capture 2D images or 3D images as needed.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1. Configuration of the device 10 according to the invention

1 and 2 show a state before assembling the reflector and a state after assembling the reflector of the camera 10 for monocular stereoscopic imaging according to the present invention, respectively. The camera 10 is largely equipped with a camera module 40, a camera main body 45 on which the camera module 40 is installed, and a reflecting mirror mounted in a standing position near the lens 42 of the camera module 40 ( 20, and a cradle 30 for mounting the reflector 20 to the camera body 30.

An example of the configuration of the camera module 40 is shown in FIG. 3, and a conventional one employing one lens may be used. The camera module 40 includes a lens module. The lens module includes a lens 42 for collecting light of an image, an image sensor 46 to be described later, and a holder 43 for aligning an optical axis of the lens 42. The camera module 40 also uses an actuator 44 for driving the lens module in a desired direction by using a driving force obtained by converting electric energy to control the focus of the camera, a driver 45 for providing a driving control signal thereto, and a lens. An image sensor (consisting mainly of a CCD or CMOS array) 46 for converting an image (light) input through the electronic signal, a signal processor 48 for processing an image signal generated by the image sensor 46, And these

components

42, 43, 45, 46, 48, etc. are mounted and the passage that can input and output signals of these elements, such that the electrical signal of the image sensor 46 is transmitted to the signal processor 48 It further includes a printed circuit board (PCB) 49 that serves.

The signal processor 48 processes an image signal obtained through the image sensor 46. A feature of the present invention is that the signal processor 48 executes a predetermined application program 50 to perform signal processing. The application program 50 inverts the image signal (refer to the left image 65 in FIG. 6 (a)) which is reflected through the reflector 20 and flipped left and right and formed on the left half surface of the image sensor 46. It has a left and right flipping function that converts the original normal image (see the left image 65 'in FIG. 6A) to be the same as the actual image. The left and right flipped image 65 'and the normal image formed on the right half surface of the image sensor 46 (see the right image 60 of FIGS. 6A and 6B) are in a side-by-side image. It consists of a (still image) or a frame (movie) to be stored in the memory. When the left image 65 'and the right image 65 are displayed in side-by-side form with a slight angle difference from each other, the two images are synthesized in the brains of the viewer who sees them with left and right eyes, respectively, and a three-dimensional image. Is recognized.

The camera body 45 may be anything as long as the camera module 40 is installed. For example, the main body of the digital camera or the main body of the smartphone or mobile phone equipped with the camera may be an example. Hereinafter will be described by taking a smartphone equipped with a camera as an example.

The reflecting mirror 20 is provided to stand immediately next to the lens 42 (in the following description, to the left side of the lens 42) to stand in parallel with the axial direction of the lens 42. The reflector 20 reflects the scene in front of the right side of the camera 10 toward the lens 42 so as to be incident (see FIG. 4). An image that is reflected from the reflector 20 and enters the lens 42, that is, a “reflection image” (a portion indicated by a dashed-dotted line in FIG. 4) is an image in which left and right are reversed.

The shape and size of the reflector 20 is that the reflected image is equivalent to half of the display 55 of the camera 10 (half of the image sensor 46. The normal number of pixels of the display of the camera is that of the image sensor 46). Since the size of the display is the same as the number of pixels, the size of the display needs to be determined to occupy the image sensor 46). Therefore, the shape of the reflector 20 is preferably rectangular. But it's not limited to rectangles. In other words, any half of the screen of the display 55 may be any shape that can generate a reflection image that occupies half of the rectangular image sensor 46. For example, trapezoids, polygons with pentagons or more, or upper and lower edges may be straight, and left and right edges may be non-linear. For example, the rectangular reflector 20 may be sized to occupy half of the display 55. That is, the size of the horizontal (x) of the rectangular reflector 20 is about the same as the size of the horizontal (a) of the display 55 of the camera 10, the vertical (y) size of the reflector 20 is the display 55 It can be set to about half of the size of (b) of. However, since the size of the reflector 20 is also affected by the refractive index of the lens 42, this criterion may not be strictly applied.

The reflecting mirror 20 is preferably installed so as to stand (ie, upright) substantially perpendicular to the lens 42, that is, parallel to the axial direction of the lens 42. However, it is not necessary to stand at right angles and may have a deviation of about ± 5 °. When the standing direction of the reflector 20 is outside the angular deviation range, the image quality of the 3D stereoscopic image is deteriorated because the reflected image and the non-reflective image show an excessively large viewpoint angle. The reflector 20 should also be installed in close proximity to the lens 42. In the case of a smartphone camera, the reflector 20 may be installed at a position approximately 4 to 7 mm away from the center of the lens 42.

The reflection mirror 20 may be installed by looking at the display 55 of the camera 10. That is, the user may adjust the installation position of the reflector 20 such that the reflected image by the reflector 20 occupies one half of the display 55. In order to facilitate the adjustment of the installation position of the reflector 20, when the user selects 3D mode shooting and the application program 50 is driven, the application program 50 divides the display 55 from side to side. It is desirable to operate the function to display the line 57 to help the user to install the reflector 20. When the installation of the reflector 20 is completed, the dividing line 57 may disappear.

The cradle 30 holds the reflector 20 so as to stand and stand by the camera module 40. According to one configuration, the holder 30 is a support plate 32 bonded to the rear surface of the reflector 20, one side is coupled to the support plate 32 and the other side is coupled to hold the edge portion of the camera body 45 It includes a holder 34. The edge portion of the camera body 45 is caught between the bottom face of the support plate 32 and the holder portion 34 by the elastic force of the holder portion 34, so that the holder 30 is attached to the camera body 45. It is fixed. The cradle can be made of a plastic injection molding that satisfies both strength and elasticity. The holder portion 34 makes the gripping force good to serve as a forceps or a clip together with the bottom surface of the support plate 32 (for example, to form a protrusion at the end of the holder portion 34 or to pad a rubber or urethane pad having good gripping force). ). Since the holder portion 34 is elastic, it is possible to flexibly correspond to various thickness sizes of the camera body 45. Although only one holder part 34 is shown in the drawing, it may be desirable to provide a plurality of holder parts 34 to obtain stable gripping force.

Another configuration example of the holder 30 may include a base portion attached to the camera body 45 and an upright portion upright in the axial direction of the lens 42 at the base portion. The reflector 20 is attached to its upright surface and stands up in parallel with the axial direction of the lens 42.

2. Image signal processing to obtain stereo image

In order to implement the present invention, an application for processing an image signal formed on an image sensor is required. 4 shows a principle that an object in front of the camera module 40 is photographed when the image is captured by the camera 10 equipped with the reflector 20. When the reflector 20 is not mounted, the front scene entering the lens 42 falls within a predetermined angle range from side to side with respect to the axial direction of the front of the lens 42. However, when the reflector 20 is installed next to the lens 42 as shown in FIG. 4, the scene in front of the left side is hidden by the reflector 20 and cannot enter the lens 42, and only the scene in front of the right side directly into the lens 42. At the same time as it enters, it is reflected by the reflector 20. In other words, the scene coming into the lens 42 is a scene of the right front of the camera 10, two images, one of which is a 'reflected image' reflected from the reflector 20, and the other is not passed through the reflector 20. It is a 'anti-reflective video' that comes in directly without. The coverages R ₁ -R ₂ of the reflected image and the coverages D ₁ -D ₂ of the non-reflective image are not exactly the same and have a slight deviation in the viewpoint. Therefore, in the image formed on the image sensor 46 through the lens 42, two images captured at different angles exist in the side by side form on the left and right sides of the image sensor 46.

The reflection image formed on the left side of the image sensor 46 is an image that has been inverted left and right by the reflector (the same sense as the left and right are reversed when viewing an object through a mirror), and the antireflection formed on the right side The image is what appears as it actually is. The reflection image is converted in real time by flipping left and right using the application program 50 as if the reflection mirror 20 did not pass through. Such conversion results in the same result as the two images having a slight angle difference from each other simultaneously on the left half and the right half of the image sensor 46 side by side (i.e., in a side-by-side form). b)). The two images are paired and stored in the image memory. In the state in which the two images are displayed on the left and right halves of the display 55, the person sees the image using a separate stereoscopic image viewing means that allows the left eye to see the left image and the right eye to see the right image. Will appear.

This will be described in more detail with reference to the flowchart of FIG. 5. 5 is a schematic diagram illustrating a signal processing process of an application program 50 which restores the image flipped left and right by the reflector 20 to the normal image again. When the camera 10 of the present invention executes a photo shooting application, the user can select one of the 2D (mono) shooting mode 82 or the 3D (stereo) shooting mode 80 on the display screen 55. To provide. 8A illustrates an image photographed by selecting the 2D photographing mode 82, and FIG. 8B illustrates an image photographed by selecting the 3D photographing mode 83. This application program 50 is not executed when the user selects the 2D shooting mode 82, but is executed only in the 3D shooting mode 80 (steps S10 and S12).

In addition to the selection of the 3D shooting mode 80, the reflector 20 should be installed before the 3D stereoscopic image is taken. In the installation of the reflector 20, the camera body 45 is sandwiched between the holder 34 and the bottom of the support plate 32 so that the reflected image by the reflector 20 occupies half of the screen of the display 55. Adjust the installation position of). In this case, the reflector 20 may be provided such that the right boundary of the reflected image coincides with the virtual dividing line 57. As another shooting preparation, the user selects one of the still cut shooting mode 84 and the moving picture shooting mode 86. When the 3D shooting preparation is completed, the user presses the shooting button 88 to start shooting (step S14).

For example, in the case of still cut photography, the left half of the image sensor 46 bears a reflection image inverted left and right by the reflector 20, and the other right half bears a normal antireflection image without passing through the reflector 20. The reflection image and the anti-reflection image are displayed on the left and right sides of the screen of the display 55 with slightly different viewpoints. As shown in FIG. 7A, the right image 70 is an antireflection image, and the left image 75 is a reflection image, and the left and right sides are reversed.

The signal processing unit 48 executes the application program 50 to invert the left and right sides of the reflected image to form a normal image. The signal processor 48 reads the signal of the reflected image formed in the left half region of the image sensor 46, performs left and right flipping of the reflected image in the internal memory, and stores the signal in a separate image memory (step S16). . The signal of the non-reflective image formed on the right half of the image sensor 46 is copied to the image memory as it is without any processing (step S18).

Right and left flipping of the reflected image is performed as follows. The signal processor 48 first calculates the number of pixels of the image sensor 46 and cuts an image corresponding to the left half of the image data recorded in the internal memory, that is, the reflected image. Then, flip the left half of the image in the internal memory as follows. That is, n vertical pixels V (i) of the image sensor 46 (i = 1, 2, 3, ..., n) m horizontal pixels H (j) (j = 1, 2, 3, ..., n m) if present, pixels V (1), V (2), V (3),... located on the left half of image sensor 46. , V (n / 2) are pixels constituting the reflected image, and thus these pixels V (1), V (2), V (3),... , The value of V (n / 2) (data stored in the internal memory) is set to V (n / 2), V ((n / 2) -1),... , V (2) and V (1) pixels are converted into values and stored in the image memory. The left and right flipping process was performed by this. Further, pixels V ((n / 2) +1),... Positioned in the remaining right half of the image sensor 46. , V (n) values (data stored in the internal memory) are pixels constituting the non-reflective image, and thus stored in the image memory as they are. Such processing is performed for each column from H (1) to H (m) to perform left and right flipping for all the pixels of the image sensor 46. For example, if the pixel data transferred from the image sensor 46 to the internal memory is 1280x720, the signal processor 48 performs left and right flipping of 640 pixels of the left half of 1280 in the internal memory, and then converts the image data into the image memory. Save it. The data of 640 pixels on the right side is copied to the image memory as it is. When all of these processes are completed, the data of the left half pixels of the image sensor 46 are the data of right and left inversion.

After the left and right flip processing on the reflection image, the reflection image and the non-reflection image are displayed on the screen of the display 55 of the camera 10 (step S20). 7 (b) shows that the non-reflective image 70 and the reflection image 75 'after the left and right flip processing are formed in side by side on the right and left halves of the screen of the display 55 of the camera 10. The example shown is shown. These two images have slightly different viewpoint angles. When these two images are stacked up and down, they appear slightly blurred due to the difference in their viewpoint angles.

In the case of video recording, the left and right flip processing of the reflected image is performed every frame and then stored in the image memory to be arranged in the form of an antireflection image and a side by side.

When shooting is finished (step S22), in case of a still picture, the RGB data of the image memory is stored in a separate storage space (for example, an SD card) in the JPG file format, and in the case of a video, 30 frames per second in the MP4 file format When it is stored in memory and a signal is received that the recording is finished, it is stored in a separate storage space (for example, SD card) in the file format (step S24). In the case of a moving picture, the left and right flipped reflection images and the non-reflected image occupy the left half and the right half of one frame, and are recorded in the image memory in units of side by side stereo image frames. In order for the left and right to be seen as a stereo image when a person looks at the screen, such left and right inversion processing of the left image needs to be performed within a time (about 1/30 second) that the human eye cannot recognize. When shooting video, operations are performed in internal memory to store side-by-side stereo video at 30 frames per second. To do this, it must be saved in at least 1/40 seconds and the stored video is saved in MP4 format.

The video obtained in this way is displayed with side by side stereo images on the screen every frame during playback (even in the case of still cut images), and the left and right eyes of the viewer are the left half and right half of the screen. If you look at the image using a means to see each of the divided areas, it is recognized as a stereoscopic image that is made into a stereoscopic image in the human brain to feel the depth of space with certainty.

In the above, the case where the reflector is applied to the smartphone camera has been described as an example, but the present invention can be applied to other types of cameras having a function of executing an application program.
