Abstract

A display device is used for a number-of-fish counting system for counting the number of fish. The display device is provided with a display unit that displays a plurality of selectable instruction items on a main screen. The plurality of instruction items include a recording instruction item that instructs a processing device of the number-of-fish counting system to execute or stop recording of video of fish, and an analysis instruction item that instructs the processing device to count the number of the fish by analyzing the fish on the basis of the recorded video.

First claim

The invention claimed is:

1. A display device for use in a fish counting system that counts a number of fish, the display device comprising:
a display unit configured to display a plurality of selectable instruction items on a main screen; and
a display control unit configured to change a display screen of the display unit in accordance with a selected one of the plurality of selectable instruction items,
wherein the plurality of selectable instruction items includes:
a recording instruction item for instructing a processing device of the fish counting system to perform or stop recording of a video of fish, and
an analysis instruction item for instructing the processing device to count the number of fish by fish analysis based on the recorded video, and

wherein, based on selection of the recording instruction item on the main screen, the display control unit is configured to change the display screen of the display unit to an operation screen that includes a recording instruction button for instructing execution or stop of the recording.

2. The display device according to claim 1 , wherein, when execution of the recording is instructed in the operation screen, the display unit is further configured to display an elapsed time after the execution of the recording is started.

3. The display device according to claim 1 , wherein the display unit is further configured to display the video acquired by an imaging unit on the operation screen.

4. The display device according to claim 1 , wherein the display unit is further configured to display the number of counted fish on the operation screen when the number of fish is counted by the processing device based on the video, along with the recording of the video.

5. The display device according to claim 1 , wherein:
based on selection of the recording instruction item on the main screen, the display control unit is configured to change the display screen of the display unit from the main screen to the operation screen via a camera adjustment screen, and
the display unit is configured to:
display the video acquired by an imaging unit on the camera adjustment screen, and
display a setting region for performing settings associated with brightness of the video and an imaging direction of the imaging unit.

6. The display device according to claim 5 , wherein:
the display control unit is configured to change the main screen to the operation screen via the camera adjustment screen and an area setting screen, and
the display unit is configured to display, on the area setting screen, areas of targets of counting of the number of fish in an adjustable manner in the video acquired by the imaging unit.

7. The display device according to claim 1 , wherein, based on selection of the analysis instruction item on the main screen, the display control unit is configured to change the display screen of the display unit to a file management screen that includes an analysis instruction button for instructing counting of the number of fish by analyzing the fish based on the recorded video.

8. The display device according to claim 7 , wherein the display unit is further configured to display, on the file management screen, a display instruction button for instructing a change to a result display screen which displays a result of the fish counting.

9. The display device claim 7 , wherein the display unit is further configured to display, on the file management screen, an output instruction button for instructing an output of a result of the fish counting to an outside.

10. The display device according to claim 1 , wherein the plurality of selectable instruction items further include an initial setting screen change instruction item for instructing a change to an initial setting screen for setting a species of the fish to be analyzed.

11. The display device according to claim 1 , wherein the plurality of selectable instruction items further include a maintenance screen change instruction item for instructing a change to a maintenance screen.

12. A fish counting system comprising:
the display device according to claim 1 ;
an input unit for selecting an item to be displayed on the display unit of the display device; and
the processing device configured to count the number of fish in accordance with the selection of the item by the input unit.

13. A display control program product storing instructions that, when executed by a computer, cause the computer to:
display, on a main screen of a display unit of a display device, a recording instruction item for instructing a processing device of a fish counting system to perform or stop recording of a video of fish; and
display, on the main screen of the display unit of the display device, an analysis instruction item for instructing the processing device to count the number of fish by analyzing the fish based on the recorded video, and
change a display screen of the display unit in accordance with a selected one of a plurality of selectable instruction items that include the recording instruction item and the analysis instruction item,
wherein, based on selection of the recording instruction item on the main screen, change a display screen of the display unit to an operation screen that includes a recording instruction button for instructing execution or stop of the recording.
