Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention digitizes and records other information, not color information, in a certain pixel of a digital moving image, and, when reproducing the moving image, obtains recording information from the pixel, The color information is interpolated from the color information of the surrounding pixels and reproduced, so that the moving image and various data at the time of shooting can be simultaneously recorded and reproduced without using a plurality of measurement recording files. The present invention relates to an information recording apparatus and an apparatus for reproducing information from a moving image, a method, a program, and a recording medium.
[0002]
[Prior art]
The following methods are available for measuring and recording information such as temperature at the same time as video shooting.
[0003]
Patent Document 1 “Video data storage device” is available. In this method, short-term video recording is switched to long-term video according to the conditions of various signals taken in from a sensor or the like in parallel with shooting. Here, the signal itself taken from the sensor is used as a trigger for recording an image, and the recording of the signal itself is not mentioned.
[0004]
As a method of recording what is not color information as a video, there is, for example, Patent Document 2 “Imaging system and temperature measurement method using the same”. This is capable of photographing an object, measuring the temperature distribution of the object with high accuracy, processing an image, calculating temperature information, and displaying the image and the temperature information on a display means. The measuring means has a control means for interrupting the temperature measurement or the temperature calculation when at least one of the output signals of the respective color lights from the video processing means does not reach a preset value. .
[0005]
Patent Document 3 “Video recording / reproducing system” is characterized in that environmental information other than video and audio signals is recorded in an audio signal channel such as a magnetic tape which is a recording medium of a video camera.
[0006]
To summarize, in the conventional method, the color information is recorded only in the part where the moving image is recorded, and although the temperature information is converted to the color information like an infrared camera, the color information is recorded. No information other than the color information is recorded in the moving image portion. This is because, if something other than the one corresponding to the color information is recorded in the moving image information recording unit, the image quality of that part is different from that of the surroundings, so that the image is deteriorated.
[0007]
In general, when recording information other than image signals and audio signals in video shooting, etc., relatively small amounts of information such as the shooting date and time and time code can be recorded at the same time. When recording the sound, there have been only means such as recording in a file other than the video file or using a part of the audio recording channel.

[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0015]
In the embodiment of the present invention, the data having the same bit depth as the bit depth of the color information of a moving image and representing the bit depth including the amount of fluctuation, the recording pixel position, and the like are collectively referred to as fluctuation data. Information other than the recording pixel position is referred to as a fluctuation amount.
[0016]
The most important feature of the embodiment of the present invention is that it has means for digitizing time-varying information, that is, means for recording the amount of fluctuation as a pixel value in some pixels of a video file.
[0017]
Examples of the information that fluctuates over time include measurable physical quantities such as temperature, humidity, pressure, atmospheric pressure, blood pressure, concentration, wind power, and light quantity.
[0018]
FIG. 1 shows the basic concept of the present embodiment. When there is an amount that fluctuates along the same time axis as a video, the amount is recorded in a pixel of a moving image that should be originally recorded as color information or luminance information. By recording in the image recording unit, information to be recorded at the recorded pixel position is lost, but if the number of recorded pixel positions is sufficiently small compared to the number of pixels of the image recording, the apparent Useful data can be recorded without impairing the naturalness.
[0019]
Further, as shown in FIG. 2, it is more effective to change the pixel position to be recorded for each frame so as not to spoil the natural appearance of the image information as much as possible.

Consists of
[0022]
It should be noted that the audio recording section is not directly related to the means of the present invention, and therefore, description of portions relating to audio is omitted in this specification. Of course, this does not prevent recording of audio data in the video recorded by the present invention, similarly to the conventional video file.
[0023]
The operation of the present embodiment will be described using an example. When applying the present embodiment, what kind of variation is recorded, what is the type of data, what is the range of numerical values, how many recorded values are It is assumed that the information of what is the unit of is known in advance. These pieces of information are not essential in the present invention, but may be separately recorded as a data file in addition to the basic information described later, or may be recorded in a header portion of a moving image. This may be used at the time of reproduction.
[0024]
In any case, these pieces of information do not need to be recorded as time-series data, unlike data that fluctuates over time, and therefore have a small recording capacity.
[0025]
Further, there may be a plurality of pixel positions for recording the variation data. However, since it can be realized by a combination of one pixel, the case of one pixel will be described. Obviously, this can be extended to multiple pixels.
[0026]
First, in the basic information setting function 100 shown in FIG. 3, basic information, that is, position information indicating at which position of the first frame of the recording start the variation data of the first frame is to be recorded, and the bit depth of the variation amount , And a bit depth for describing the position information. For example, as shown in FIG. 5A, in the case where the fluctuation amount and the position information are recorded, the total value corresponds to the bit depth per pixel of the moving image. When the variation includes luminance information, as shown in FIG. 5B, the sum of the luminance information recording unit, the variation recording unit, and the position information recording unit corresponds to the bit depth per pixel of the moving image. Set to For ease of explanation, unless otherwise confused, luminance information is also included in the variation.
[0027]
Hereinafter, the bit depth per pixel of an image is B, the bit depth for position recording (horizontal direction) is W, the bit depth for position recording (vertical direction) is H, and the bit depth for variation recording is d = B− (W + H). ). The position of the pixel for recording variation data in the initial frame is (w0, h0).
[0028]
These information need not be recorded as an external file as long as they are all common in the form using the present invention, but otherwise, they are output by the basic information recording function 130.
[0029]
Next, moving image information such as a video signal is stored in a short term by the moving image short-term storage function 101. At the same time, the measurement amount other than the video signal and the audio signal is stored in a short term by the fluctuation amount short-term storage function 102. The order of storage is not important, but the amount of change is stored in the same cycle as the moving image. If it is desired to record at a shorter cycle than the moving image, the number of the variation data to be recorded in one frame of the moving image may be increased and the recording may be performed for a plurality of pixels.
[0030]
Next, the fluctuation amount is converted by the fluctuation amount conversion function of 111 at the bit depth for the fluctuation amount set by the basic information setting function of 100.
[0031]
The recording position storage function 112 determines which pixel position in the next frame is to be recorded, and stores the pixel position.
[0032]
The change data recording function of 113 is determined by the data converted by the change amount conversion function of 111 into a predetermined pixel position of the moving image stored by the moving image short-term storage function of 101, and the recording position storage function of 112. This is a function of recording the fluctuation data recording position of the next frame.
[0033]
Then, the moving image generated as a result of the variable data recording function of 113 is recorded and output to the external storage device by non-compression or lossless compression by the moving image recording function of 121.
As described above, it is possible to record a time-varying measurement amount as a pixel value of a moving image, which is an object of the present invention.
[0034]
When reproducing a video file recorded according to the present invention, the following process is performed. The basic information accompanying the moving image to be reproduced is read by the 200 basic information reading function in FIG. 4, and the bit depth B per pixel of the moving image, the bit depth for position recording (horizontal direction) W, the bit depth for position recording (Vertical direction) H, the bit depth d for fluctuation recording d = B- (W + H), and the fluctuation data recording pixel position (w0, h0) of the initial frame are acquired.
[0035]
Next, a moving image is read by the moving image reading function 201 and stored one frame at a time.
[0036]
Next, the recording position acquisition function 202 acquires at which pixel position of the stored frame the variation data is recorded. For the initial frame, the pixel position (w0, h0) is known. The second frame can be obtained from the fluctuation data of the initial frame, and thereafter, is obtained recursively.
[0037]
Next, the fluctuation data is read from the recording pixel position by the fluctuation data reading function 203. For the second and subsequent frames, the recording pixel position is acquired from the fluctuation data by the recording position acquisition function 202.
[0038]
Next, the measured amount is obtained from the fluctuation data read by the fluctuation data reading function of 203 by the fluctuation amount conversion function of 204, converted into a usable form, and stored by the fluctuation amount storage function of 205. How to convert the data and how to use the stored amount depend on the usage of the present invention and are not in the scope of the present invention.
[0039]
Next, the color information of the portion where the variation is recorded is determined by the pixel value interpolation function 211. At this time, for example, the average of the surrounding pixel values may be taken, or when the recording position of the variation data is different from the immediately preceding frame, the color information of the same pixel position of the immediately preceding frame may be used. This interpolation method is not essential for the present invention.
[0040]
Next, the interpolated moving image is stored by the moving image storage function 212. How to use the stored moving image depends on the use form of the present invention.
[0041]
In the above description, when the pixel position varies from frame to frame, there is a method of recording the recording pixel position of the previous frame in the current frame. In this case, at the time of reproduction, instead of sequentially reading information as in the following embodiment, a process of reading out information after reading up to the last frame once is performed. In this case, the frame number is not incremented from the first frame but decremented from the last frame.
[0042]
[Example]
Hereinafter, examples of the present invention will be described.
First, an embodiment on the recording side will be described.
The position on the image is taken with the origin at the upper left corner, the x-axis to the right, and the y-axis downward, and the position of the pixel on the image can be represented by an integer value from the origin.
[0043]
In this embodiment, the bit depth per pixel of an image is 24 bits, the bit depth for position recording (horizontal direction) is 4 bits, the bit depth for position recording (vertical direction) is 4 bits, and the bit depth for data recording is 16 bits. Bit (24− (4 + 4)), and the variation can be described within a range of 16 bits. The recording position in the initial frame is (w0, h0) = (0, 0). These pieces of information are output to another file as a file accompanying the recorded moving image.
[0044]
For example, assume that a sensor and a video camera are connected to a computer. The signal from the sensor is synchronized with the video camera, and is input to the computer every 1/30 second, for example.
[0045]
Hereinafter, the frame number is represented by i (i = 0, 1,...), The i-th moving image is represented by I (i), and the i-th variation is represented by D (i).
[0046]
In a step after the start of recording, a moving image I (0) is acquired and stored on the short-term storage device. At the same time, the signal from the sensor is also stored. The signal from the sensor may be represented by any number of bits at this stage. The conversion method at this time is not the essence of the present invention.
[0047]
At this stage, the sensor signal is converted into 16 bits, and this is represented as D '(0). The video signal I (1) of the next frame is acquired and stored on the short-term storage device. At the same time, the signal from the sensor is also stored.
[0048]
Decide where to record in the next frame I (1). For example, in this embodiment, since the horizontal and vertical directions are represented by 4 bits (16), a pixel position within a distance of 16 pixels vertically and horizontally from the current recording position (0, 0) is determined. Although the means for determining the pixel position is not the essence of the present invention, for example, it is desirable to have the same color information as the surrounding color information in order to interpolate the color information of this pixel portion during reproduction. This position is defined as (w1, h1).
[0049]
At this stage, since the information to be written is prepared at the position (w0, h0), w1, h1, and D '(0) are written at the position (w0, h0) of the image I (0).
[0050]
Hereinafter, this process is repeated. The procedure is as follows:
1. Set the initial recording position P (0).
2 Acquire and store the image I (0).
3 Acquire and store information D (0).
4 Store the recording pixel position P (i) on the video I (0).
5 Set i = 0 and repeat the following.
6 Information D (i) is described with a specified bit depth d, and this is defined as D '(i).
7 Obtain and store the video I (i + 1).
8 Obtain and store information D (i + 1).
9 Determine the recording pixel position P (i + 1) on the video image I (i + 1).
10 Reference recording pixel position P (i) on video I (i).
11 Overwrite the position P (i) on the image I (i) with D ′ (i) and P (i + 1).
12. Write out video I (i).
13 If the processing is ended, the processing is ended. If not, i is incremented, and the processing returns to 7.
[0051]
FIG. 6 is a flowchart showing this processing procedure.
In FIG. 6, a moving image bit depth (B) is set (601), a variation bit depth (d) is set (602), a position information bit depth (W + H) is set (603), and a frame number i is set. As 0 (604), the recording pixel position (P (i = 0)) in the initial frame is set. The steps so far are executed by the basic information setting function 100 in FIG. Then, the variation bit depth (d), the position information bit depth (W + H), and the recording pixel position (P (i = 0)) in the initial frame are recorded by the basic information recording function 130 (606). Then, the moving image I (i = 0) of the first frame is read and stored by the moving image short-term storage function 101 of FIG. 3 (607), and the fluctuation amount to be recorded in the first frame by the fluctuation amount short-term storage function of 102 D (i = 0) is read and stored (608).
[0052]
Next, the process enters a loop from step 609. The fluctuation amount D (i) is converted into D ′ (i) by the fluctuation amount conversion function 111 in FIG. 3, and the moving image I (i + 1) of the next frame is read and stored by the moving image short-term storage function 101 (FIG. 3). 610), the fluctuation amount D (i + 1) is read and stored by the fluctuation amount short-term storage function of 102 (611), and the process returns to step 609 as i = i + 1.
[0053]
On the other hand, the recording position P (i + 1) of the next frame is determined and stored by the recording position storage function 112 in FIG. 3 (612). Then, the recording position P (i + 1) of the next frame and the converted i-th fluctuation amount D ′ (i) converted by the fluctuation data recording function 113 are the recording positions P (i) of the moving image I (i) of the i-th frame. Recorded in i) (613). Next, the moving image I (i) of the i-th frame is recorded by the moving image recording function of 121 (614). In the moving image I (i) recorded here, the pixels other than the recording position P (i) are the same as the pixels of the normal moving image, but the recording position P (i) is The recording position P (i + 1) of the next frame and the converted i-th variation D ′ (i) are recorded.
[0054]
Note that a case where the recording pixel position is not changed at all is a special case of this processing, and the following processing flow is performed with W = H = 0.
1. Set the initial recording position P (0).
2 Set i = 0 and repeat the following.
3. Acquire and store the video I (i).
4 Acquire and store information D (i).
5. The recording pixel position on the video image I (i) is P (i) = P (0).
6 Overwrite D '(i) on position P (i) on video I (i).
7 Write out video I (i).
8 If the processing is ended, the processing is ended. If not, i is incremented and the processing returns to 3.
Next, an embodiment on the reproducing side will be described.
[0055]
On the reproduction side, the bit depth per pixel of the video is 24 bits, the bit depth for position recording (horizontal direction) is 4 bits, the bit depth for position recording (vertical direction) is 4 bits, the bit depth for data recording is 16 bits, and The initial recording pixel position (0, 0) is obtained by reading the basic information file.
In the present embodiment, it is assumed that the pixel value is interpolated by the average value of the surrounding color information.
[0056]
The moving image is read, and the color information of the first frame is obtained and stored. At this time, the data recorded at (0, 0) is converted, and information D '(0) of the first frame is obtained. At the same time, the information recording pixel position P (1) of the second frame is obtained.
[0057]
Next, the color information at the (0,0) position is interpolated by taking an average value of surrounding pixel values. In the case of (0, 0), the neighboring pixels have three points of (1, 0), (1, 1), and (0, 1). Therefore, the average value of the color information of these three points may be used. For example, when there are 9 pixels around, the average value for 9 pixels may be used. When the recording pixel position of the previous frame is different, the color at the same position of the previous frame may be used. In any case, this interpolation method is not an essential problem of the present investigation.
[0058]
After the interpolation, the image information of the first frame is output and the variation information associated with the first frame is output and stored in the storage unit. Also, the information recording pixel position P (1) of the second frame is stored in the storage unit.
[0059]
By repeating the above, a moving image and information recorded in a certain pixel of the moving image can be acquired and used.
1 Set the pixel value interpolation method.
2 Read the data file if necessary.
3 B, W, H and d are obtained.
4 Acquire the initial recording position P (0).
5 Set i = 0 and repeat the following.
6 Acquire and store the video I (i).
7 Obtain and store D '(i) from P (i) on I (i).
8 The data and the recording position P (i + 1) in the next frame are obtained from D ′ (i).
9 Store P (i + 1).
10. Interpolate the color information at the position P (i) on the video I (i).
11 Write out the image I (i).
12 Increment i and return to 6.
[0060]
FIG. 7 is a flowchart showing this processing procedure.
In FIG. 7, first, an interpolation method for interpolating a pixel at a recording position of variation data is set (701). Then, the basic file is read by the basic information reading function 200 in FIG. 4, that is, the variation bit depth (d), the position information bit depth (W + H), and the initial recording pixel position (P (i = 0)) are obtained. (702). Next, the first moving image is read by the moving image reading function 201 (703), the frame number i is set to 0 (704), and the loop from 705 onward is entered.
[0061]
The moving image I (i) of the i-th frame is read and stored by the moving image reading function 201 in FIG. 3 (705). Data on the recording position P (i) of the i-th frame is acquired by the recording position acquisition function of 202 (706), and the recording position P (i + 1) of the next frame is acquired and recorded from this data (707). . Then, the converted fluctuation amount D ′ (i) recorded in the i-th frame is acquired by the fluctuation data reading function of 203 (708), and the fluctuation amount D ′ (i) converted by the fluctuation amount converting function of 204 is obtained. ) Is converted to the variation D (i) before conversion (709), and the variation D (i) is stored by the variation storage function of 205 (710).
[0062]
On the other hand, the color information at the recording position P (i) of the i-th frame is interpolated by the pixel value interpolation function 211 of FIG. 3 (711), and the color interpolated at the recording position P (i) where the variation data is recorded. The information is overwritten (712), and the moving image I (i) of the i-th frame is stored (713).
[0063]
It is apparent that a computer program can be created based on the above-described flowchart, and that the program can be recorded on a recording medium or provided through a network.
[0064]
As described above, the invention made by the inventor has been specifically described based on the above-described embodiments and examples. However, the present invention is not limited to the above-described embodiments and examples, and departs from the gist of the invention. Of course, various changes can be made without departing from the scope.
[0065]
