Abstract

PURPOSE:To select and display hands having various shapes arbitrarily, by providing a means, which determines clock display patterns in correspondence with time data, reads characters out of a character generator and converts the data into video signals. CONSTITUTION:When the hands of a clock are displayed, a CPU 1 inputs time data, determines the display patterns of the hands corresponding to the time from a program stored in a program ROM 3 in accordance with said data and reads characters out of a character generator 2 in correspondence with said patterns. The characters are written into a video RAM 5 from a video processor 4. The content, which is written in the RAM 5, is outputted as a video signal. The video signal is added to an RGB encoder, which is connected to a the video signal line of a TV receiver. The video signal is displayed on a CRT instead of an image signal. Or the video signal is mixed with the image signal and displayed on the CRT in a superimposed pattern. In this way, the hands which are arbitrarily selected among many kinds of shapes can be displayed simply.

This clock display device inputs time data and calculates a line connecting the base end (center) and tip position of each hand (that is, the part displayed as a hand) according to the current time. A method is adopted in which the dot display position is determined and the dot is displayed accordingly.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

Examples of the present invention will be described below. FIGS. 1 to 3 are diagrams showing one embodiment thereof. Reference numeral 1 denotes a CPU that controls the entire system, to which time data is input at a timing of 8 times/second. 2 is a character generator that stores a plurality of characters that are part of the hands, 3 is a ROM for a display program in which a display pattern according to the above-mentioned time data is programmed in advance, and 4 is a video signal for clock display (including a synchronization signal). 5 is a video RAM that temporarily stores the contents of the clock display format.

The characters stored in the above-mentioned character generator 2 are characters having a size of 8×8 dots, and are configured so that a part of the necessary needle is included within the size of the character. For example, the shape of the needle A shown in FIGS. 2(a) to 2(C) is composed of a plurality of unit characters X represented by mouths (squares).

Now, in order to display the hands of the clock, the time data (
The CPU inputs data (indicating hours, minutes, and seconds), and according to that data, a display pattern for the hands corresponding to that time is determined by the Floodram stored in the program ROM 3, and the character generator 2 Read characters from. Then, this character is written from the video processor 4 to the video RAM 5,
The contents written in the video RAM 5 are output as a video signal. This video signal is added to an RGB encoder (not shown) connected to the video signal line of the television receiver, and is displayed on the CRT instead of the video signal.
Alternatively, it is mixed with a video signal and displayed on a CRT in a superimposed format.
