面に表示させる制御手段とを有する魚群探知機。[Scope of Claim for Utility Model Registration] A school of fish that displays detected images on a display device using a main screen represented by m pixel rows and a window screen represented by n pixel rows and inserted into the main screen. The first detector is a detector that can hold h pieces of received data that are input sequentially.
buffer memory, a first video memory that holds the display data of the main screen, and k pieces of received data that are sequentially input (k>mh/n
) and a second buffer memory that can hold window screen display data.
video memory, a video signal synthesis circuit that synthesizes the display data of the first and second video memories and outputs it to the display, and a new h
, k pieces of received data are held, the held h, k pieces of data are output as display data corresponding to an image of one pixel column on the main screen and window screen, respectively, and the output display data are respectively The display data corresponding to the image of the oldest pixel row in the first and second video memories is replaced with new display data, and when the first video memory or the second video memory retains the new display data, the image is displayed. Scroll the main screen or window screen of the display device displayed on the signal synthesis circuit by one pixel column, and display data newly stored in the first video memory or second video memory in the vacant space after scrolling. a control means for displaying an image based on the image on a main screen or a window screen.
