Abstract
A fish finder 1 comprises a transducer that transmits an ultrasonic wave and receives a reflected reception signal. An echo image memory 181 stores echo images generated based on the received reception signal. When in a state where at least one of the echo images is read from the echo image memory, an operation receiver 10 receives an instruction to change the read echo image. A detecting module 171 detects fish based on the received reception signal and detection information is stored in a detection result memory 172. An image processor 18 reads an echo image generated before the at least one echo image from the echo image memory, changes the echo image to output and superimposes the corresponding detection result on the changed echo image in response to the instruction. The fish finder may further comprise a display unit 19 and a positional information detector. The operation receiver may receive a specifying operation of a geographical position and the image processor can then change the echo image according to the specified geographical position.

And, as shown in figure 5, image processing part 18 is among the echo keeping image storage 181, read
The echo of the 1 picture amount (longitudinal direction of display part 19 and horizontal resolution amount) of display part 19, exports to display part 19.
As a result, the echo of repeatedly measurement is shown on display part 19.
As shown in fig. 6, on display part 19, showing and transverse axis distributed with ping and to echo obtained by longitudinal axis distribution depth
Image.In the example of fig. 6, show the echo 201 of a part of shoal of fish in picture left end, show on the right side of picture central authorities
The echo 200 of the shoal of fish.Additionally, showing the echo in seabed on the downside of picture.
Further, in the example of fig. 6, show seabed depth (in figure is expressed as 302m) as the knot of seabed detection process
Really and shoal of fish information (rectangular histogram 203 of in figure).
The information that seabed depth and shoal of fish information are exported by the test section 171 in signal processing part 17.As Fig. 2 institute
Show, test section 171 is parsed with reading receipt signal memorizer 170 from receipt signal, carries out detection and the sea of the shoal of fish
Bottom detection etc. is processed.
In the detection process of the shoal of fish, including at least the detection process having fish length.By more than such as defined threshold connecing
The collection of letters number is considered as the shoal of fish, length (average length) of size (sample number), mean intensity or depth direction according to this shoal of fish etc.
Detection fish length.Additionally, test section 171 can also carry out the detection of fingerling.For example by the echo with the shoal of fish as benchmark
Matching degree (similar degree) differentiate fingerling.
In the detection of seabed depth, for example with the side on the basis of the timing of the receipt signal receiving more than certain threshold value
The method or method etc. on the basis of highest timing is changed into by differential value.
Test section 171 will so detect obtained by various information (testing result) remain to testing result holding storage
In device (suitable with the testing result maintaining part of the present invention) 172.Now, the information with the measurement timing of the receipt signal being parsed
(such as moment) creates and associatedly keeps testing result.
Additionally, control unit 14 instruction test section 171 output and appointed region (example in the display picture of display part 19
Region 202 as Fig. 6) corresponding testing result.User passes through to operate position and the size of operating portion 10 designated area 202.
Control unit 14 would indicate that the information output of the timing (measurement timing) obtaining the specified echo in region 202 to test section
171.
Test section 171 reads measurement timing among in testing result holding with the testing result of holding memorizer 172
Consistent testing result, exports to control unit 14.Control unit 14 will export to image from the testing result that test section 171 inputs
Reason portion 18.The testing result inputting from control unit 14 is overlapped on echo and exports by image processing part 18.
Accordingly, in the display picture of display part 19, show rectangular histogram 203 for example shown in Fig. 6 as testing result.
Wherein, the display form of testing result is not limited to rectangular histogram 203, for example, can also only show the numeral of fish length.In addition, in profit
User carries out during the operation of the scope of the fish length of display, scheming in rectangular histogram 203 for change by operating operating portion 10
The scope of the fish length as shown by processing unit 18 changes.That is, test section 171 will be greater than reality in rectangular histogram 203
The testing result of the scope amount of scope of display remains in testing result holding memorizer 172.User carry out for
During the operation of scope of change fish length, 18 object informations extracting specified scope of image processing part, overlap echo
On image and export.
And, when user passes through to operate operating portion 10 to carry out for making operation that echo in the past show, scheme
As processing unit 18 reads echo in the past among image storage 181, make exported echo consecutive variations, and
And overlap the testing result of the shoal of fish on echo.
For example, possess in the case that rotation carries button in operating portion 10, if user enters to exercise the behaviour that this rotation proposes button rotation
Make, then control unit 14 accepts as the operation for making echo in the past show.Control unit 14 indicates image processing part 18
Follow and operate via the display that operating portion 10 accepts, make shown echo consecutive variations.
For example, it is described as follows situation: in the such as display picture of Fig. 6, user is in order that the shoal of fish that shows in left end
Echo 201 is near picture center side, and carries out for making the operation of the continuous side shifting to the right of echo (for example make rotation
Propose the operation to anticlockwise for the button) situation.
If operating portion 10 has accepted for making rotation propose the operation to anticlockwise for the button, control unit 14 indicates image processing part
The echo in the past of 18 reading time quantums corresponding with rotation amount.As shown in fig. 7, image processing part 18 is from image storage
Read the echo in the past of the time quantum being instructed in 181, make exported echo.Accordingly, on display part 19
The echo of display carries the rotation consecutive variations of button according to rotation.That is, as shown in Fig. 8 (a), if user makes rotation
Carry button to anticlockwise, then the echo 201 of the shoal of fish of left end gradually moves to picture center side.
So, the shoal of fish is found out machine 1 and follows the display operation of user and show with making echo consecutive variations in the past
Show.Additionally, now, the testing result of the shoal of fish overlaps on echo.Therefore, the echo of the user shoal of fish to be observed
Both will not disappear from picture, and also also can will not confirm target in target location (such as central authorities) display, user simultaneously
The testing result of the shoal of fish.
In addition, above-mentioned " making echo consecutive variations " mean to make echo every time with the display pixel of display part 19 it
In 1 pixel as least unit change.Certainly, also corresponded to continuously with multiple pixels (such as 2 pixels) change every time
Change.
In addition, in the example of Fig. 8 (a), even if in the case that user makes rotation propose button rotation, region 202 is not yet
Meeting appointed change in location in display picture.In the example of Fig. 8 (a), due to not yet the shoal of fish is detected in region 202,
Therefore rectangular histogram 203 does not whatever show.But, such as shown in Fig. 8 (b), make rotation carry button further to left-handed in user
Turn, during the operation of inside that the echo 201 entering to exercise the shoal of fish moves to region 202, from testing result holding memorizer
The testing result of the echo 201 of this shoal of fish is read in 172.Therefore, in rectangular histogram 203, show the reflectogram of the shoal of fish
Information as 201 testing result.
Then, with reference to the flow chart of Fig. 9, illustrate that the shoal of fish finds out the action of machine 1.First, the shoal of fish is found out machine 1 and carries out ultrasound wave
Transmitting-receiving (s11).And, the shoal of fish finds out the process (s12) that machine 1 carries out receipt signal.
Image processing part 18 with the elapsed time from output ultrasonic wave correspondingly, generates echo corresponding with depth
(s13).Additionally, signal processing part 17 carries out the shoal of fish detection process of the detection process including fish length.
Subsequently, the echo being generated is remained to (more new images storage in image storage 181 by image processing part 18
The content of device 181), signal processing part 17 remains to testing result in testing result holding memorizer 172 (s14).
On the other hand, the shoal of fish is found out machine 1 and judges whether user operates operating portion 10 to carry out for making reflectogram in the past
As shown in operation (s21).For example, when operating portion 10 possesses rotation and carries button, if user enters to exercise this rotation proposes button rotation
Operation, then control unit 14 accept as the operation for making echo in the past show.In addition it is also possible to be as lower section
Formula: when operating portion 10 possesses cursor key, if the cursor key in pressing left or right direction, operating portion 10 is as making in the past
The operation that echo shows accepts.
If not carrying out for the operation making echo in the past show, image processing part 18 is from image storage
Among the echo keeping in 181, read 1 picture amount (longitudinal direction in display part 19 and the horizontal resolution of display part 19
Rate amount) up-to-date echo (s22).
On the other hand, when user operates operating portion 10 to carry out for making operation that echo in the past show, scheme
Operate corresponding echo (s23) as processing unit 18 reads from image storage 181 with display.Now, image storage
181 follow display operation (rotation proposes the rotation of button) accepting through operating portion 10, make the echo reading from image storage 181
Image change, thus makes shown echo consecutive variations.Therefore, the rotation amount that echo carries button with rotation is correspondingly
Consecutive variations (s23).For example, if from the state of Fig. 6, user makes rotation carry button to anticlockwise, then the returning of the shoal of fish of left end
Ripple image 201 continuous moving to picture center side, till being in the state shown in Fig. 8 (a).Accordingly, user can one
The echo of the side visuognosiies shoal of fish to be observed, is allowed to move to target location (such as central authorities) to show.Further,
If user makes rotation carry button to anticlockwise from the state of Fig. 8 (a), the echo of the shoal of fish gradually moves as shown in Fig. 8 (b)
Move on the right side of picture.And, when the echo 201 of the shoal of fish moves to the inside in region 202, keep with depositing from testing result
The testing result of the echo 201 of this shoal of fish is read in reservoir 172.
Then, Figure 10 be represent application examples involved by the shoal of fish find out machine 1a composition block diagram.To the structure common with Fig. 1
Become mark same tag, omit the description.The shoal of fish is found out machine 1a and is also equipped with positional information test section 50.
Positional information test section 50 for example possesses gps.Each transmitting-receiving that control unit 14 presses ultrasound wave detects from positional information
Positional information is remained to positional information storage by each measurement timing by portion 50 receiving position information (latitude and longitude information)
In device (not shown).Positional information is together kept with the information (such as moment) representing measurement timing.
Image processing part 18 reads up-to-date positional information from control unit 14, such as, as shown in Figure 11 (a), be shown in display
On the position of the regulation in the picture in portion 19.
Additionally, as shown in Figure 11 (b), image processing part 18 can also obtain from control unit 14 and obtain user through operation
Measurement timing (the measurement timing of the such as right-hand member in region 202) the corresponding position of the echo in region 202 that portion 10 specifies
Information, it is together shown with testing result (rectangular histogram 203).Certainly, image processing part 18 can also show up-to-date measurement
The positional information of timing and with the corresponding positional information of measurement timing of the echo obtaining specified region 202 this
The two.
And, when user operates operating portion 10 to carry out for making operation that echo in the past shows, at image
Reason portion 18 follows makes the positional information obtaining from control unit 14 change via the display operation that operating portion 10 accepts.Image processing part
18 for example obtain to enter with the corresponding positional information of measurement timing of the echo of the right-hand member obtaining in display part 19 current picture
Row display.Additionally, image processing part 18 is corresponding with the measurement timing of the echo obtaining specified region 202 in display
During positional information, similarly, also obtain corresponding positional information from control unit 14 to be shown.
In addition, when user passes through to operate operating portion 10 input position information, image processing part 18 can also be from image
Read echo corresponding with the positional information of this input in memorizer 181, and be shown on display part 19.Accordingly, in example
As the fishing ground knowing to pass through in the past position when, user can observe the situation in water when this fishing ground again.
Additionally, if the shoal of fish finds out machine 1 being connected with plotter via communication functions such as lan, the shoal of fish finds out machine 1 can also be
The mode of the echo of position that display user specifies on plotter.In the case of being somebody's turn to do, it both can be positional information detection
Portion 50 is separately equipped on plotter, obtains positional information by this plotter or the shoal of fish finds out machine 1a and plotter profit
With same position infomation detection portion 50, sharing position information.Accordingly, user only passes through to specify the past to pass through on plotter
The position in fishing ground is it becomes possible to again observe the situation in water when this fishing ground.
