摘要:
A control device includes a storage device for prestoring rendering command data, a central processing device, and a rendering processing device. The rendering command data is data for generating a rendering command executed in order to generate display data indicating a display image to be displayed on a display device. The central processing device refers to a screen management table when a predetermined rendering condition is satisfied, and specifies and outputs rendering command specifying data corresponding to the satisfied rendering condition. The rendering processing device acquires the rendering command data specified by the outputted rendering command specifying data from storage device, generates display data based on the acquired rendering command data, and outputs the display data to the display device.

An operation terminal for remotely operating an electronic apparatus includes a processing unit for remotely communicating with the electronic apparatus in accordance with a program, a memory on which the processing unit performs writing or reading of data, a nonvolatile memory for storing a basic screen image drawing command for drawing a basic screen image that is displayed before the operation terminal is operated, a drawing processor for creating a bitmapped image of the basic screen image in accordance with the basic screen image drawing command, and a display unit for displaying the bitmapped image on a screen.

The display color of, for example, a button image responsive to a command input into a facility operation display device is controlled by a palette value having a smaller number of bits than an RGB value. When the display color of the button image is changed, the palette value of a drawing object associated with the button image is changed to an RGB value. This eliminates the necessity of incorporating, for example, a high-performance CPU as a central arithmetic unit. In addition, it is not necessary to pre-store images corresponding to several kinds of display colors specified by RGB values, to thereby eliminates the necessity of incorporating, for example, a high-capacity storage medium in the facility operation display device. Accordingly, the device cost can be reduced.

A state display device capable of reducing a processing load applied to a microcomputer by performing part of a GUI process by hardware and a display method of the state display device are obtained. A rendering processing device starts a process in response to a rendering request stored in a rendering request region when a starting command is stored in a start/end instruction register. When a rendering request specified by an instruction address is a rendering termination request, the rendering processing means terminates the process performed in response to the rendering request, stores a termination factor in an interruption factor register, and issues an interruption to a central processing device.

An application program changes a property value of a graphic object arranged in an object database. An object manager reads out the property value from the object database and then issues a drawing command. A graphics engine executes the drawing command to configure a memory image of the graphic object on a VRAM to display the image on a liquid crystal display via an LCDC.

Unit data, which constitutes digital data is extracted as 8-bit units of parallel data by a control section and outputted to a buffer. Thereafter, in a process where the unit data is transmitted from a serial interface to a display unit, the unit data is converted to parallel data in a format required by the display unit. Thereby, it becomes unnecessary for the control section to perform processing of converting the digital data to a format required by the display unit. Consequently, the load on the control section is reduced.
