ができる。 FIG. 5 shows a flowchart of a program related to driving the indicator. Maximum depth D, number of indicators n
In this case, the instruction increments are D/n. When the program starts, the depth y is set to 0 in step 21, and the loop of steps 22 to 25 is repeatedly executed to give a turn-off signal to the light emitting elements between the depth 0 and the set value y1 . while depth y
Then, D/n is added (K+1) in increments to y, and when y eventually exceeds y1 , the process advances to the "NO" branch from step 23, and then the loop of steps 26 to 29 is repeatedly executed to obtain the depth y1. While giving a lighting signal to the light emitting elements in the range from y2 to y2 , increments D/n are added to the depth y.Next, when y exceeds y2 , the loop of steps 30 to 33 is executed. A turn-off signal is given to the remaining light emitting elements, and the program ends. In this way, the enlarged range can be displayed by lighting up the light emitting elements between y1 and y2 .

つた。 According to the present invention, the entire scanning range is divided into n layers, and n sliding sensitivity adjustment knobs are provided to individually adjust the sensitivity of each layer, and the light emitting elements indicating the magnified area are Since we provided one adjustment knob for each of the n adjustment knobs and only turned on the ones within the enlarged display range, it is easy to determine which of the n knobs will be effective in adjusting the gain of the image that is currently being enlarged. understood intuitively,
Sensitivity adjustment operations have become easier, eliminating unnecessary operations.
