Description

  The present invention relates to an image processing method and an image processing program for processing an image of a subject. In particular, the present invention relates to an image processing method and an image processing program characterized by an image selection process for estimating the state of a subject.

In general, when a subject is photographed, an image file obtained by digitizing an image is handled.
At that time, there is a case where it is desired to know the state of the subject in the image recorded in the image file.
For example, there is a case where it is desired to know whether or not the target subject exists in the image recorded in the image file.
For example, there is a case where it is desired to know whether the proportion of the subject in the image recorded in the image file is small or large.

  Conventionally, when there is such a request, a time-series image of an image file is image-analyzed with a predetermined algorithm. For example, a collection of pixel data in the entire frame of the image is processed with a specific algorithm.

On the other hand, when a subject is photographed to generate an image file, it is common to obtain a small file size by performing digitization using a predetermined compression processing algorithm. In the compression processing algorithm for an image file of a certain moving image, moving image data is recorded by paying attention to the difference between time-series images. In this way, the file size of the image file obtained by digitizing using the compression processing algorithm is smaller than the file size of the image file obtained by digitizing without using the compression processing algorithm.
Even when digitization is performed using the same compression processing algorithm, the file size of images arranged in time series varies depending on the state of the subject.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In each figure, common portions are denoted by the same reference numerals, and redundant description is omitted.

An image processing program according to the first embodiment of the present invention will be described.
First, an image processing apparatus that uses an image processing program will be described with reference to the drawings.
FIG. 1 is a conceptual diagram of an image processing system according to an embodiment of the present invention.
The image processing system includes a photographing machine 10, a computer 20, and a data center 30.
The photographing machine 10 is a device that photographs a subject. For example, the photographing machine 10 is a digital camera or an analog camera.
The digital camera captures a subject, digitizes it with a predetermined compression processing algorithm, generates an image file, and transmits it in time series.
The analog camera captures a subject and outputs a video signal. The video signal is digitized by a dedicated electronic circuit using a predetermined compression processing algorithm to generate an image file, and is transmitted in time series.
For example, the camera 10 captures a subject for a predetermined time, digitizes it into an MPEG format, generates an image file, and sequentially transmits the image file to the computer 20 via an electronic communication line. The file size of the generated image file is smaller than the file size when the image is simply digitized.
The image file is a moving image file or a still image file.
The image is a moving image or a still image.
The moving image may be a moving image recorded in a moving image file, or may be a moving image generated from still images recorded in a plurality of still image files.
The still image may be a still image generated from a moving image recorded in a moving image file, or may be a file recorded in a still image file.

The file sizes of a plurality of image files arranged in time series vary depending on the state of the subject.
For example, the file size of the image file when the subject movement is large is larger than the file size of the image file when the subject movement is small.
In addition, the file size of the moving image size when the brightness of the subject is high is larger than the file size of the image file when the brightness of the subject is low.
When the subject is a landscape, the file size of the image file when there are many moving objects in the landscape is larger than the file size of the image file when there are few moving objects in the landscape.
Further, the file size of the image file in a state where the shape and color of the subject are complicated is larger than the file size of the image file in a state where the shape and color of the subject are monotonous.
This seems to be related to the mechanism of the compression processing algorithm when digitizing.

The computer 20 is a computer having a CPU, an internal storage device, an external storage device, a keyboard, a monitor, and various interfaces, and is a personal computer, for example.
The computer realizes an image processing function by an image processing program.

The electronic communication line is the Internet, a telephone line, a mobile phone radio, a general radio, or the like.

The data center 30 is a computer that can store and communicate data.
For example, the data center 30 is a computer connected to the Internet and acting as a WEB server.

The customer 40 has a personal computer, a mobile terminal, and a mobile phone.
The customer 40 can receive data from the computer 20 by a personal computer, a mobile terminal, or a mobile phone, or can access the data center 30 and download the data.

The image processing program according to the first embodiment will be described below with reference to the drawings.
FIG. 2 is a functional block diagram of the image processing apparatus according to the first embodiment of the present invention.
The image processing program is a program that causes the computer 20 to execute the image processing function F10 in order to process an image of a subject.
The computer 20 can communicate with the photographing machine 10 that photographs a subject.
The image processing function F10 includes an image file acquisition function F11, a file storage function F12, an image file selection function F13, an image distribution function F14, and an image upload function F15.

The image file acquisition function F11 is a function for acquiring a plurality of digitized image files obtained by photographing a subject from a photographing machine.
The image file acquisition function F11 may be a function of acquiring a plurality of image files arranged in time series by photographing a subject from a photographing machine, digitizing the image using a predetermined compression processing algorithm.
For example, a setting command is sent to the digital camera 10. The setting command is a command for setting a projection angle, a projection time, a projection sampling time, a compression processing algorithm parameter, and the like.
The computer 20 receives a plurality of image files from the digital camera 10 at every projection sampling time.

The file saving function F12 is a function for saving a plurality of image files in an external storage device.
The computer 20 stores the received image file in the external storage device of the computer 20 in time series.

The image file selection function F13 is a function for selecting a specific image file from a plurality of image files obtained by photographing a subject and digitizing the image based on the respective file sizes.
For example, this is a function for selecting a specific image file from a plurality of image files based on the size of the image file.
A specific image file may be selected from an image file having a large file size among a plurality of image files arranged in time series. For example, an image file having the maximum file size among a plurality of image files is set as the specific image file. In addition, for example, an image file that falls within a predetermined size width that is equal to or less than the maximum file size is selected from a plurality of image files, and the image file selected according to a predetermined rule is selected as the specific image file from the image files. To do. In this way, an image file with a lot of subject movement can be selected as a specific image file from a plurality of image files. In addition, a specific image file can be selected from among a plurality of image files.
A specific image file may be selected from image files having a small file size among a plurality of image files arranged in time series. For example, an image file having a minimum file size among a plurality of image files is set as the specific image file. Further, for example, an image file that falls within a predetermined size width that is equal to or larger than the minimum file size is selected from a plurality of image files, and the image file selected according to a predetermined rule is selected as the specific image file from the image files. To do. In this way, an image file with less subject movement can be selected as a specific image file from a plurality of image files. Further, a specific image file can be selected from among a plurality of image files as an image file having a low brightness of the subject.

When the subject includes a landscape, and the weather condition when the landscape is photographed is the first weather condition, a specific image file is selected from the image files having a large file size among the plurality of image files, When the weather condition when the landscape is photographed is the second weather condition, a specific image file may be selected from the image files having a small file size among the plurality of image files. In this way, image files in different states can be selected according to changes in weather conditions. Here, the first weather condition and the second weather condition are not the same. In particular, the first weather condition and the second weather condition may be weather conditions that do not occur simultaneously.
For example, if the subject includes a landscape and the weather conditions at the time of shooting the landscape are not the specific weather conditions, select a specific image file from a large image file among multiple image files arranged in time series If the weather condition when the landscape is photographed is a specific weather condition, the specific image file may be selected from among a plurality of image files arranged in time series with a small file size. In this way, image files in different states can be selected according to changes in weather conditions.

The scenery may include a wave that the subject hits the coast. In this way, a plurality of image files can be selected in response to changes in the state of the waves that strike the coast.
For example, an image file may be selected from the image file having a large file size among a plurality of image files arranged in chronological order, which is a landscape including a wave of a subject hitting the beach. In this way, an image file including an image having a large wave or a lot of waves hitting the coast can be selected as the specific image file.
For example, an image file may be selected from the image file having a small file size among a plurality of image files arranged in time series, which is a landscape including waves that the subject hits the coast. In this way, an image file including an image with a small wave or a small wave that strikes the coast can be selected as the specific image file.

For example, the subject is a landscape including waves that hit the coast, and a specific weather condition is a state in which a typhoon is off the shooting point. In this case, a strong and large sea urchin reaches the coast.
For example, if there is no typhoon when shooting a landscape, if you select a specific image file from large image files among multiple image files arranged in chronological order, and a typhoon is coming when shooting a landscape Alternatively, the specific image file may be selected from image files having a small file size among a plurality of image files arranged in time series. In this way, when the waves are small, an image file that captures a relatively large wave is selected as the specific image file, and when the waves are large, an image file that captures a relatively small wave is selected as the specific image file. Can be selected as a file.
In this way, when there is no typhoon, it is possible to specify a landscape with as many waves as possible or a landscape with as much waves as possible. When a typhoon is present, it is possible to specify a landscape with as few waves as possible or a landscape with as little waves as possible. Therefore, it is possible to specify a waved image suitable for marine leisure such as surfing.

Further, for example, a specific weather condition may be a state in which strong wind (sea breeze) from the sea is blowing. The wind speed in this case is, for example, a wind speed of 8 m or more.
When distributing an image for enjoying marine leisure such as surfing, it is usually preferable to select and distribute an image showing a state in which more large waves reach the coast and collapse. For this purpose, an image file having a large file size is selected. However, when the wind blows from the sea toward the shore, the wave front collapses, and the wave height increases with three strokes as a shaggy. In such a case. By selecting an image file with a small file size, it is preferable to distribute a gentle timing wave to the surfer.

The image distribution function F14 is a function for distributing an image recorded in a specific image file.
The image is a moving image or a still image.
The image file is a moving image file or a still image file.
For example, the specific image file is transmitted to the personal computer, mobile terminal, mobile phone, etc. of the customer 40.
For example, a new image file is acquired from the specific image file, and the image file is transmitted to the customer's 40 personal computer, mobile terminal, mobile phone, or the like.
For example, the still image included in the specific image file is transmitted to the personal computer, mobile terminal, mobile phone, etc. of the customer 40.

The image upload function F15 is a function that enables browsing of an image recorded in a specific image file through communication.
The image includes a moving image and a still image.
For example, the specific image file is uploaded to the data center 30.
For example, a new image file is acquired from the specific image file, and the image file is uploaded to the data center 30.
For example, a still image included in the specific image file is used as an image file, and the image file is uploaded to the data center 30.
The data center 30 is a WEB server.
The customer 40 is a personal computer or a mobile terminal. A specific image file, an image file, and an image file can be downloaded using a mobile phone or the like, and an image recorded in the specific image file can be viewed.

From the results of Example 1, the following was found.
(1) If there is undulation, the file size increases.
(2) When the wave front breaks down, the file size increases.
(3) Lightness difference and color tone of landscape. If the contrast is different, the file size changes.
(4) In the distant view, the change in file size is small.

Next, the file size of a still image taken with a digital camera will be described.
An image of a desk with nothing: 215K bytes An image of a ballpoint pen on the desk taken in a distant view: 226K bytes An image of a ballpoint pen on the desk taken in a close view: 424K bytes A colored pencil in a case on the desk was taken in a distant view Image: 101 Kbytes Image of a colored pencil in a case on the desk taken in a close-up view: 147 Kbytes Image taken by approaching a colored pencil in a case on the desk: 174 Kbytes Coast with two white waves broken into pieces Photo taken: 378 Kbytes Image taken of two shores with two white waves that collapsed broadly: 397 Kbytes Image taken of three shores with white waves broken apart: 399 Kbytes

From the results of Example 2, the following was found.
(1) When the shape, color, and contrast of the subject are complicated, the file size increases.
(2) The file size changes depending on the presence / absence and size of the subject.
From this, it is presumed that the file size changes depending on the change in the number of cars at the intersection and the presence or absence of a subject on a certain screen.
(3) The file size changes due to the difference in brightness of the soup (white foam portion) and swell, which are the size of the wave.

From the above embodiment, the subject is photographed and digitized by a predetermined compression processing algorithm to obtain a plurality of image files arranged in time series, and a specific image is selected from the plurality of image files based on the file size of the image file. It has been found that when a file is selected, an image file containing an image in a specific state can be selected.
In addition, from the above embodiment, the subject is photographed, digitized by a predetermined compression processing algorithm, a plurality of image files arranged in time series are obtained, and the state of the subject is estimated based on the file size of the image file. It turned out that you can.

If the image processing method and the image processing program of the above-described embodiment are used, the following effects are exhibited.
Since a specific image file is selected from a plurality of image files obtained by photographing a subject and digitized based on each file size, a video file corresponding to the state of the subject affecting the file size can be selected.
Capture a subject with a camera, digitize the image with a compression algorithm and generate an image file repeatedly, obtain multiple time-series image files, and then create a file from the multiple image files A specific image file is selected based on the size, and the image recorded in the specific image file is distributed to the customer or uploaded to the data center. The customer can use a personal computer, mobile terminal, mobile phone, etc. Can browse.
Also, if the subject movement is large or the subject brightness is high, the file size of the image file becomes large, so a specific image is selected from among the multiple image files arranged in chronological order. When a file is selected, an image file including an image with a large subject movement or an image with a high brightness of the subject can be selected.
Also, if the subject movement is low or the brightness of the subject is low, the file size of the image file becomes small. Therefore, the specific image is selected from the image files with the smallest file size among multiple image files arranged in time series. When a file is selected, an image file including an image with a small movement of the subject or an image with a low brightness of the subject can be selected.
In addition, since the subject is a landscape, either the large file size image file or the small file size image file is selected depending on the weather conditions at the time of shooting the landscape. It is possible to select an image file that includes either one of the large or small images or the image with high or low brightness of the subject.
Also, since the subject is a landscape that includes waves rushing to the coast, selecting a specific image file from multiple image files based on the file size of the image file will correspond to the size and number of waves rushing to the coast. To select an image.
In addition, since the specific image file, the image file, and the image are distributed to the customer's personal computer, mobile terminal, mobile phone, and the like, the customer can view the image according to his / her interest.
In addition, specific image files, image files, and images are uploaded to the data center, so customers can download and view images that suit their interests.
Also, if the subject movement is small, the file size of the image file will be small.If the subject movement is large, the file size of the image file will be large.If the subject brightness is high, the file size of the video size will be large. If it is low, the file size of the image file becomes small. Therefore, if the state of the subject is estimated from the time series change of the file size of multiple image files, the state of the subject can be estimated by a simple procedure such as comparing the file sizes. .
Further, since it is estimated that the movement of the subject is small when the time-series change width of the file sizes of the plurality of image files is smaller than the predetermined value, the movement of the subject can be estimated by a simple procedure.
Moreover, since the estimated state is distributed to the customer's personal computer, mobile terminal, mobile phone, etc., the customer can know the state of the subject.
Further, since the estimated state is uploaded to the data center, the customer can know the state of the subject.
In addition, since the state of the subject can be notified without distributing the image itself, it is easy to protect human privacy when the subject is a human.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
In the image processing method, the example in which both the image distribution process and the image upload process are performed has been described. However, the present invention is not limited to this, and only one of the image distribution process and the image upload process may be performed.
In the image processing method, the example in which both the state communication step and the state upload step are performed has been described. However, the present invention is not limited to this, and only one of the state communication step and the state upload step may be performed.
Moreover, although the image file acquisition process demonstrated in the example which receives the image file which the camera image | photographed, it is not limited to this, You may prepare an image file by what kind of means beforehand.
