Methods and apparatuses perform image processing for blending image and/or data layers. The method according to one embodiment accesses data representing a first layer and data representing a second layer; and generates a blended layer by adjusting a transparency of said first layer relatively to said second layer based on data associated with said first or second layer.

Chart display device and method for displaying chart

Methods and apparatuses process sensing signals. A method for redrawing a sensing image when a range is or has been changed, according to one aspect of the present invention, records the sensing image and outputs the sensing image to a display; records additional information displayed upon a screen and outputs the additional information to the display; computes a new image from the recorded sensing image using an image manipulation computer function, so that the computed image fits a new scale of the changed range, and recording the computed image; and computes changes to the recorded additional information to adjust the additional information to the new scale of the changed range, and records the computed additional information.

Radar apparatus and the like

A display having a screen providing historical water depth information and a screen providing fish school detection information is presented. The water depth information and the fish school detection information may be derived from an echo signal, and can be displayed simultaneously or alternated separately on the display by switching. When the water depth reaches or is less than a predetermined value, an alarm may be provided on the display and/or an alarm sound may be generated. As the alarm is displayed the brilliance of the display may be raised to a maximum brilliance, making the display brighter so the contents are easier to see.

Underwater detecting apparatus, depth measuring apparatus and display apparatus

A screen on which water depth information obtained from an echo signal is historically displayed and a screen on which fish school detection information obtained from an echo signal is displayed, are displayed side by side on a display screen of a display instrument or either one is displayed by switching. Thus, a large amount of information is displayed on a limited space of a small display instrument efficiently and effectively and to be easy to see. Further, when a water depth value becomes a set value of an alarm water depth mark or less, an alarm is displayed on the display screen of the display instrument, and an alarm is given by sound. At the same time as this, the brilliance of the display screen is raised to the maximum brilliance to make the screen brighter, so that the contents of the alarm are made easy to see. Thus, quick measures can be taken in an emergency. Moreover, after a mode is set to a help mode by a mode switch, when any one of keys in an operation portion is pushed, guidance of the function, operation procedure, and the like of the pushed key is displayed on a display portion. Thus, the guidance as to the key can be displayed by a simple operation in a help mode.
