DISPLAY APPARATUS CAPABLE OF PROCESSING DISTANCE INFORMATION

BACKGROUND OF THE INVENTION

1. Field of the Invention The present invention generally relates to an image

display apparatus capable of processing distance infor mation. More speci?cally, the present invention is di rected to an automobile mount type television receiving apparatus equipped with a map meter function.

2. Description of the Prior Art Very recently, liquid crystal television receivers

equipped with a liquid crystal display panel have been widely utilized. In particular, such liquid crystal vtelevi sion receivers are mounted on automobiles. However, these automobile mount type liquid crystal television receivers merely have the function to receive television broadcasting programs, but have no other functions speci?c to car use. On the other hand, a so-called “map meter” has been

marketed so as to actually measure a distance over posi tions on a map, while moving on a surface of this map. Also, wrist watches equipped with the function of a map meter are recently commercially available. How ever, this type of map meters have small-sized display units, which is difficult to observe, and also merely represent the distances. This implies that such wrist watches do not have a drive guidance function. On the other hand, there have been marketed auto

mobiles equipped with navigation functions. However, since such automobile navigation systems require satel lites and CD-ROM (Compact Disk-Read-Only Mem ory), there are problems of large-sized apparatus and very high cost.

SUMMARY OF THE INVENTION

The present invention has been made in an attempt to solve the above-described various problems, and there fore has an object to provide an image display apparatus including a television receiver and a map meter func tion, which is easily observed and manufactured at lower cost. An image display apparatus with a calculation func

tion for processing distance information, according to the present invention, comprises. measurement means for measuring a distance; input

means for inputting time information; calculation means for calculating a velocity from both a distance measure ment result of the measurement means and the time information inputted from the input means; and

display means for displaying a calculation result made by the calculation means. With such an arrangement, the image display appara

tus according to the present invention can readily pro vide suitable auto.drive information so that travel schedules may be easily and precisely established.

ation process of the image display apparatus shown in FIG. 1A; FIG. 11 is a flow chart for explaining an operation

process of the image display apparatus during an initial setting operation; FIG. 12 is a ?ow chart for representing an operation

process of the image display apparatus in a measuring mode; FIG. 13A shows signal waveforms outputted from

the respective phototransistors in response to rotations of a scanning roller; . FIG. 13B shows signal waveforms which are ob

tained by shaping the signal waveforms shown in FIG. 13A; FIG. 14 shows waveforms for representing differ

ences in the waveforms when the scanning roller is rotated in the normal direction and reverse direction; FIG. 15 is a flow chart for showing an operation

process of the image display apparatus in a map mode; FIG. 16 is a ?ow chart showing an operation process

of the image display apparatus in a navigation mode; FIG. 17 is a flow chart for showing an operation

process of the image display apparatus in a schedule mode; FIG. 18 is a ?ow chart for explaining an operation

process of the image display apparatus in an execution mode; FIG. 19 is a flow chart for explaining an operation

process of the image display apparatus in a correction mode and, FIG. 20 is a flow chart for explaining an operation

process of the image display apparatus in a result dis play mode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to drawings, a liquid crystal television apparatus equipped with a so-called "map meter”, to which the present invention has been applied, will be described.

In FIG. 1, there is shown an outward appearance of the liquid crystal television apparatus according to one preferred embodiment of the present invention. The liquid crystal television apparatus is so constructed of a television main body 50 shown in FIG. 1A; a remote controller 51 shown in FIGS. 1B and 1C, and a connec tion cable 52 for connecting the television main body 50 and the remote controller 51.

In the television main body 50, there are arranged a display unit 53 comprising a color liquid crystal display
