Description

Method for generating a dynamic image using partial optical blocking {Method for generating a dynamic image using partial optical blocking}

The present invention relates to a method for generating an image, and in particular, sets a specific part of an image sensor constituting a digital camera as a blocking area or an acceptable area, and sets a blocking method (or an acceptable method) and exposure level in the blocking area or allowed area. And, it relates to a dynamic image generation method using optical partial blocking to generate a dynamic photo or video by taking a picture while giving a change in focus.

A high-end SLR (Single Lens Reflect) camera or a DSLR (Digital Single Lens Reflex) camera without a mirror is a mirrorless DSLR camera that uses a flash synchronizing technique or a slow shutter technique. Various dynamic shooting is possible. However, these cameras are not only expensive, but also have a narrow range of utilization in that they perform only a single function, that is, a camera function.

Recently, with the development of mobile camera (hereinafter referred to as mobile camera) technology installed in a mobile device such as a smartphone, users can easily take pictures with a mobile camera instead of an existing SLR/DSLR camera. However, since mobile cameras do not have optical functions that existing high-end SLR cameras have, these limitations are compensated for by adding color conversion and animation using software filters. Ordinary digital cameras used by ordinary people, not high-end digital cameras, can be treated on the same level as mobile cameras.

In relation to mobile cameras (or ordinary digital cameras), contents related to software filters that change the color of images or add animations to already recorded images are being introduced, but they are not optical contents, but software. Since they are virtual photos and videos made of enemy content, users tend to recognize that these photos and videos are not real photos and videos.

In order to fully understand the present invention and the advantages in operation of the present invention and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings describing exemplary embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, the present invention will be described in detail by describing preferred embodiments of the present invention with reference to the accompanying drawings. Like reference numerals in each figure indicate like elements.

First, terms used in the present invention are defined.

The term video includes both photos (still images) and moving images (moving images), unless otherwise specified. A camera includes both a general digital camera and a camera mounted in a mobile device such as a smart phone, unless otherwise specified.

The entire capturing area (hereinafter referred to as a capturing area) means the entire area to be captured by a camera. The blocking area is a part of the capturing area designated by the user. The capturing area is captured by the camera, but an image of the blocking area is not generated, and only an image of an area other than the blocking area is generated. The allowable area is designated by the user for a part of the capture area, but contrary to the blocking area, only the allowable area is generated when the camera captures the capture area, and no image is generated for parts other than the allowable area.

A camera module installed in a camera generally includes a filter, an optical lens, and an image sensor installed from the outside to the inside of the camera. The above-described blocking area or allowable area will be recognized and processed by the image sensor. For example, when external light that passes through a filter and an optical lens and reaches an image sensor implemented as a plurality of pixels (picture elements) is converted into an electrical signal, a blocking area and a permissible area are defined in pixels arranged in a matrix form. Since it can be implemented by signal processing separately, it will not be described in detail here.

1 describes a dynamic image generation method using optical partial blocking according to the present invention.

Referring to FIG. 1, a dynamic image generation method (100, hereinafter, dynamic image generation method) using optical partial blocking according to the present invention includes a blocking area setting step 110, a blocking method setting step 120, and a focus setting step 130. ), image correction step 140 and image storage step 150 are performed.

In the blocking area setting step 110, the user sets the blocking area in the shooting area, and in the blocking method setting step 120, the blocking order of the set blocking area, blocking time, and blocking rate are determined. In the exposure & focus setting step 130, the focus movement is set when the camera is photographed, and in the image correction step 140, the blocking ratio for each area occupied in the image is set, the images are merged, and the exposure is corrected. A final image is generated, and in the image storage step 150, the final image as well as all data images used to generate the final image are stored together.

Hereinafter, the above five steps will be described in detail.

Figure 2 explains the blocking area setting step.

Referring to FIG. 2, in the blocking area setting step 110, a direct definition step 111 in which the user directly defines the blocking area and a shape selection definition step 112 in which the user selects and defines the blocking area from among the shapes provided by the camera ), a blocking area area adjustment step 113 for adjusting the area of the first set blocking area, and a blocking area dividing step 114 for dividing the finally set blocking area.

The user may primarily set the blocking area by performing one of the direct definition step 111 and the figure selection definition step 112.

In the direct definition step (111), the user's hand designates the cut-off area on the touch screen panel of the camera. The user may set the cut-off area by displaying a closed loop using a finger (111-1). It can be implemented in various ways, such as a method of inputting (111-2) three or more edges of the area with a finger and setting them by connecting them with a line in a camera processor (not shown).

In the figure selection definition step 112, the camera provides various types of figures, and the user selects at least one of them to designate as a blocking area. (112-1), if there is no figure that matches the blocking area, select a plurality of figures, move them to the place you want to designate, overlap them, and then make the closed circuit formed by their outlines become the blocking area (112-2). When there are multiple blocking areas, each blocking area can be defined by selecting one of two methods (112-1, 112-2) for the corresponding blocking area. In addition, when setting a plurality of blocking areas, it is possible to use figures of the same shape, but it is also possible to select and use different figures. (112-3)

Since the blocking area and the allowed area are the same in terms of setting the area, in the following description, the blocking area will be described and applied to the allowed area, unless there is a need to distinguish them.

In the step of adjusting the area of the blocking area (113), the firstly set blocking area can be used as it is by performing one of the above two steps (111, 112), but it is performed when it is necessary to adjust the shape or area of these areas. The area of the blocking area is adjusted by a scaling method (113-1) that expands or contracts the firstly set blocking area as a whole or a selective adjustment method (113-2) that selectively expands or contracts a part of the blocking area. By doing so, the blocking area can be finally set.

The step 114 of dividing the blocking area is performed so that the user can visually recognize the final blocking area determined through at least one of the three steps 111, 112, and 113, and It is preferable to reproduce the outline (114-1) of the blocking area set as , on the display panel of the camera, or by applying a specific color to the blocking area (114-2) or shading (114-3).

Figure 3 explains the blocking method setting step.

Referring to FIG. 3 , in the blocking method setting step 120, the blocking order setting step 121 and the blocking area ratio setting step 122 are performed.

In the blocking order setting step 121, the order in which the finally set blocking area is to be blocked is set, and the method of blocking the entire blocking area at once (121-1) and the method of sequentially blocking according to the order specified by the user ( 121-2). The method (121-2) of sequentially blocking according to the order specified by the user, for example, to block radially from the outside to the center or from the center to the outside of the blocking area, or from one side of the blocking area to the other direction can be blocked with In the method of sequentially blocking (121-2), it is preferable to start blocking the blocking area and to set the time period during which the entire blocking area is blocked.

In the step of setting the ratio for each blocking area (122), the shooting ratio (hereinafter referred to as blocking ratio) of the blocking area and the opposite area (non-blocking area) of the area defined as the blocking area is set (122-1), or Set the time interval (hereinafter referred to as blocking time) in which the blocking area is used during the shooting time. It is possible to set the blocking ratio and blocking time for each blocking area, but conversely, an embodiment in which they are set for each non-blocking area (122-3) will also be possible.

In the focus setting step 130, an image such as background blur is obtained by adjusting the blocking area and the focal length of the lens. In particular, it is set when you want to take a picture of your face with a camera, that is, a Selfie picture. This can be achieved.

For example, set the periphery of one's face as a blocking area (or set one's face as an acceptable area), take a picture in the center of one's face with a focal length tailored to one's face for a certain period of time, and then During a certain period of time, the focal length of the lens is moved to the shortest lens focal length or the maximum lens focal length while taking pictures of parts other than the face of the user, and the pictures are combined. The face revealed in this combined image will become clearer through the blurry background.

However, the focus setting step 130 is not essential and can be selectively used only when obtaining a background blur image as described above.

In the above description, most of the blocking area setting step 110, the blocking method setting step 120, and the focus setting step 130 are described as being performed by the user's selection, but in reality, the menu provided by the camera processor In response to, it is performed by the user selecting or designating.

Steps 140 and 150 to be described below will be performed by the processor of the camera according to a preset program according to the settings in the preceding three steps 110, 120 and 130.

Figure 4 explains the correction step of the image.

Referring to FIG. 4 , in the image correction step 140, a block ratio setting step 141 for each region, an image merging step 142, and an exposure correction step 143 are performed.

In the blocking ratio setting step 141 for each area, a blocking ratio of a blocking area and an area opposite to the blocking area is set. That is, the input value of light incident to the image sensor of the camera is forcibly blocked at a set ratio. One embodiment would be to set the blocking ratio of the blocking area to 100% and to set the blocking ratio of the area opposite to the blocking area to 0%. In addition, an embodiment in which the blocking ratio of the blocking area is 80% and the blocking ratio of the area opposite to the blocking area is 10% will be possible. As described above, the blocking ratio setting step 141 for each region may also be performed through a user input process according to a menu provided by the camera processor.

In the image merging step 142, a previously captured image of the blocking area is merged with an image in which the blocking area is not captured. In this way, a static image of the blocking area can be merged with a moving image of an area opposite to the blocking area. These operations are performed by the processor of the camera according to a preset program, and the exposure correction step 143 described below is also performed by the processor of the camera.

In the exposure correction step 143, the exposure amount of the blocking area is corrected or, conversely, the exposure amount of the area opposite to the blocking area is corrected. Here, the term "correction" is used as a concept that includes both reducing and increasing the amount of exposure. When it is determined that it is difficult to use the captured image as it is according to the cutoff ratio set in the blocking method setting step 120, the image may be corrected by adjusting the amount of exposure of the captured image.

For example, when it is determined that the exposure amount of the blocking area is excessive, a new image with a reduced exposure amount can be created from the image of the blocking area. It will be possible to create a new image with an increased amount of exposure in the image of the area.

A final image may be generated by going through the image correction step 140 . The generated final image will include, for example, an image in which a still image and a moving image are mixed, and an image in which a clear still image and a blurry image around the still image are mixed.

The image storage step 150 is performed by the camera processor, and all basic images used to generate the final image as well as the final image generated through the above-described steps 110 to 140 are stored. Storage locations vary, and may be stored, for example, in the memory of a camera or in an external memory. The base image includes an image before correction and an image after correction. Since the basic image is stored, various final images desired by the user can be newly created later.

Examples of using the present invention are described below.

5 illustrates an example of capturing an image using a blocking area set by a user.

In the upper part of FIG. 5, assuming that the user captures the shooting area for 3 seconds, the rear display of the camera reproducing the shooting area before shooting, in order from the leftmost to the right in the upper part of FIG. 5, between 0 and 1 second, 1 It represents one frame selected from images taken between ~2 seconds and between 2 and 3 seconds, respectively.

In the following description, unless otherwise specified, it is assumed that a plurality of images indicated by one drawing number (not a member number) is a sequence of images taken while the camera is fixed in one direction.

In the first, third, and fourth pictures, the shaded person represents the area selected by the user as the blocking area, and the entire recording area is taken without blocking until the first 1 second of the 3-second recording time (the second Figure), it can be seen that for the next 2 seconds, images are obtained by proceeding with recording (third and fourth figures) excluding the blocking area from the recording area.

Referring to the second drawing, the person designated as the blocking area and the vehicle located near the person were photographed as they are. It can be seen that only the vehicle slightly moved to was photographed, and at this time, the vehicle is also covered in the part where the person set as the blocking area is located. In the fourth drawing, it can be seen that as time passes, the front part of the vehicle moving in the direction of the person is more covered than in the third drawing.

The lower part of FIG. 5 shows the final image obtained by performing the image merging step according to the present invention with respect to the image taken through the process shown in the upper part of FIG. 5 .

Referring to the lower drawing of FIG. 5, the final image obtained by performing the image merging step 142 of the image correction step 140 of the present invention with respect to the image taken through the process shown in the upper part of FIG. 5 is obtained. For example, an image of a person included in the second image may be overlapped with the third and fourth images. From the final image shown in the lower portion of FIG. 5 , it can be seen that the vehicle continues to move in the direction of the person while the person continues to remain motionless (see arrow) with eyes open or eyes closed.

What is to be described in FIG. 5 is an example of a method of utilizing the blocking area as it is, and a method of utilizing the remaining area except for the area set as the blocking area in the shooting area, that is, an inverted area of the set blocking area is also possible.

6 illustrates an example of capturing an image by utilizing an inverted area of a blocking area set by a user.

Assuming that the user captures the recording area for 3 seconds, the upper part of FIG. 6 shows, in order from the leftmost to the right, the rear display of the camera that reproduces the recording area before recording, between 0 and 1 second, between 1 and 2 seconds, and It is the same as in FIG. 5 to indicate one frame selected from images captured between 2 and 3 seconds.

Referring to the leftmost drawing, the blocking area is set for a person as in the example of FIG. 5 , but the images displayed in the third and fourth drawings are different from those of FIG. 5 . In FIG. 6, the parts shaded from the second to the fourth are inverted areas of the blocking area, and the entire shooting area is taken without blocking in the second drawing, the same as in FIG. 5, but the third and fourth drawings are blocked. It can be seen that the photographing is performed for the person designated as the area, but the photographing is not performed for the vehicle in the inverted area of the blocking area.

The lower drawing of FIG. 6 shows the final image obtained by performing the image merging step according to the present invention with respect to the image taken through the process shown in the upper part of FIG. 6 .

Referring to the final image shown in the lower part of FIG. 6 , it can be seen that the person normally blinks or moves (refer to the arrow), but the car remains stationary. It can be seen that this is opposite to the final image shown at the bottom of FIG. 5 .

The utilization of the blocking area and the inversion area of the blocking area has been described with reference to FIGS. 5 and 6 . Hereinafter, the use of the allowed area will be described.

7 illustrates an example of using an allowed area.

Referring to FIG. 7, the human eye was set as an allowable area in the recording area in which both a person and a vehicle were included (arrow in the drawing on the left), and the total recording time was 3 seconds, and the entire recording area for 0 to 1 seconds, 1 to 1 second. It can be seen that if only the allowable area is photographed for 2 seconds and then corrected, a final image in which the human eye blinks (arrow in the right figure) but the vehicle does not move (right figure) is obtained.

Even when a plurality of blocking areas or allowable areas are defined in the imaging area, the present invention can exhibit effects. At this time, the blocking ratio and focus may be different for each blocking area.

FIG. 8 describes an embodiment in which two blocking areas are set in the shooting area, and shooting is performed by setting different focal points and different blocking ratios in each of the blocking areas.

The shooting area shown in FIG. 8 includes two people and a vehicle. The first blocking area is set for the person in the lower left corner and the second blocking area is set for the person in the middle on the right. The total shooting time is 3 seconds. Suppose that during 0 to 1 second, the entire shooting area is normally recorded, for 1 to 3 seconds, the first blocking area is blocked at 100% rate, and for 1 to 2 seconds, the second blocking area is blocked at 50% rate. do.

Referring to the leftmost drawing of FIG. 8 , it can be seen that a person in the first blocking area is closest to the camera, a person in the second blocking area is next in distance, and a vehicle is farthest from the camera.

The person in the first blocking area is photographed normally between 0 and 1 second, and for the following 1 to 3 seconds, the face is 100% blocked and parts other than the face are photographed. Therefore, the part of the person in the first blocking area other than the face will be photographed for 0 to 3 seconds. A person in the second blocking area is photographed normally between 0 and 1 second, only 50% is photographed between 1 and 2 seconds, and photographed normally between 2 and 3 seconds. Since the vehicle has no blockage at all, every movement from 0 to 3 seconds will be filmed.

Therefore, as shown in the rightmost drawing of FIG. 8, in the final image, the human face in the first blocking area will hardly change, and then the human face in the second blocking area will next have little change. Movements of vehicles that are not included are reflected in the video as they are.

9 shows an image that changes according to a change in focus of a lens during a photographing process.

Referring to FIG. 9, the first drawing from the left shows a state (0 m sec) before starting recording, and the fifth drawing starting from the second drawing shows 0 to 20 ms, 21 to 40 ms, 41 to 60 ms, and 61 ms, respectively. It is one frame extracted from an image taken at ~80 ms, and the lower part of the second to fifth figures shows the focus of the lens when the figure is taken.

The second drawing was created with the human eye set as the allowable area in focus, and from the third to the fifth drawing, the focus moves from the human eye to the human background, and the final focus is only between the human and the background. stay It can be seen that the person and the background become blurred at the same time from the third to the fifth picture according to this shift of focus. It can be seen that the change of the focal length results in the change of the created screen.

In the present invention, it is possible to obtain an image of background blur by using the change in focal length during shooting together with a blocking area (including an inversion area and an allowable area of the blocking area).

10 explains the setting of the allowable area and the adjustment of the focal length of the lens according to the shooting time according to the present invention.

Referring to FIG. 10, when a permissible area (arrow) is set for the human eye among a person and a vehicle displayed on a smartphone display (left drawing), and the shooting time is set to 100 ms (milliseconds), the permissible area is allowed for the first 20 ms. Then, for 21~80ms, the inversion area of the permissible area is photographed by setting the focus of the lens to the shortest or longest distance (lower right drawing), and normal for the remaining 81~100ms. shoot in focus (not shown)

Referring to the drawing on the right side, since the focus of the lens is on the human eye, which is an acceptable area, the human eye can be captured as a clear image, but the background (vehicle) behind the person will be a blurry image. (Refer to Image 1) Referring to the drawing on the lower right, it can be confirmed that since the focus of the lens is set to the shortest distance, not only the person but also the background (vehicle) behind the person is blurred. (see image 2)

As described above, it can be seen that various basic images can be generated by adjusting the focal length and utilization of the blocking area according to the setting of the blocking area and the shooting time. Here, the basic image means all images captured with different focal points according to the capturing time. In the final image obtained by performing the image correction step 140 according to the present invention, a background image in which the human eyes are clear but the background other than the human eyes is blurred may be obtained. The advantage of the present invention can be demonstrated in that a user can directly define an area to obtain a clear image and proceed with photographing.

In the present invention, when correcting an image (140), it is said that the exposure is corrected (143). Of course, even at this time, the concept of the allowed area (blocking area) proposed in the present invention can be used.

While the shooting area is being photographed, the same exposure is maintained in the non-blocking area, but the blocking area is not photographed at all for a set period of time, so the total exposure will be reduced compared to areas other than the blocking area. Therefore, in view of this point, in the present invention, it is possible to perform exposure correction when correcting an image even after capturing as well as before capturing.

11 illustrates an example of underexposure correction.

The upper figure in FIG. 11 explains before exposure compensation, and the lower figure explains after exposure compensation, respectively.

Assuming that the total recording time is 100 ms, if the person defined as the blocked area is not photographed for 20 ms, the person in the blocked area will be exposed for a total of 80 ms, but the area other than the blocked area will be fully exposed for 100 ms. . Referring to the upper drawing of FIG. 11 , it can be seen that the underexposed area, that is, the person set as the blocking area is photographed darker than the surroundings.

In order to improve this disadvantage, considering the exposure time in the blocking area and the area other than the blocking area, the exposure of the blocking area may be set higher than that of areas other than the blocking area before shooting. As described above, this function can be realized by mapping a plurality of pixels constituting an image sensor, distinguishing them, and processing signals. Referring to the lower drawing of FIG. 11 , it can be confirmed that the dark part of the image due to the exposure difference between the blocking area and the surrounding area is significantly improved after correction.

Compensation of the blocking area and exposure may be used as a concept of compensation as shown in FIG. 11, but may also be used to make the blocking area stand out compared to the surroundings as described below.

12 illustrates examples of underexposure and overexposure.

In FIG. 12, when a person and a vehicle are being reproduced in the video, the person's face is set as the first blocking area and the entire remaining part of the same person excluding the first blocking area is set as the second blocking area (left drawing), During 0 to 20 ms of the 100 ms shooting time, the exposure of the 1st blocking area was set by increasing to +2, and the exposure of the 2nd blocking area was set to -4 during 10 to 30 ms, and the rest of the area was set to default exposure (0, zero). Suppose you shoot with Here, + means that the exposure amount is increased compared to the basic exposure (overexposure), and - means that the exposure amount is decreased compared to the basic exposure (underexposure).

Referring to the drawing on the right of FIG. 12 , the face of a person, which is the first blocking area, is exposed more than the basic exposure, so it shines the most in the entire shooting area. The exposed second blocking area is displayed darker than the vehicle.

In the above, the technical idea of the present invention has been described together with the accompanying drawings, but this is an illustrative example of a preferred embodiment of the present invention, but does not limit the present invention. In addition, it is obvious that anyone skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
