If the current time is January, characters and patterns for the New Year are displayed first. Next, the microcomputer 57 determines whether or not the title advance button 52b has been pressed (S1 in FIG. 7).
4). If it has not been pressed, the process ends. As a result, the title is combined with the video signal from the camera unit 1 and recorded in the VTR unit 4. Further, if the title feed button 52b is pressed, the next title (in FIG. 8, characters or patterns of the adult type) is displayed. If the January title has no purpose and is sent, the characters and patterns of general titles such as zoos and parks are displayed next.

It is also possible to configure an operation that combines FIG. 3 and FIG. 7, that is, referring to area information and time data, and displaying the titles related to the area information preferentially. The flowchart may be configured to input the time information of the internal clock next to S4 in FIG. FIG. 9 shows an example of the priority algorithm in that case. In this way, the titles that match the current time (season, month, etc.) are displayed based on the area information and time data, and after the titles for each month are complete, general titles for each area (not necessarily for each area) are displayed. In this case, if the internal clock 54 is the world clock,
It is possible to set the time at the same time as setting the area.

The present invention is not limited to the above-mentioned embodiments, and various modifications can be made based on the spirit of the present invention, and they are not excluded from the scope of the present invention. For example, the following modifications can be considered in the operation examples shown in FIGS. 7 and 8. (1) First, the title of the same month as the current month obtained from the internal clock is displayed. Next, the next month, the next next month, and so on are displayed in this order. Alternatively, it is displayed in the order of the next month, the previous month, the second next month, the second previous month, and so on. (2) Classify the titles by month and day, and first display the title of the same month and day as the current month and day obtained from the internal clock. If not, the title of the closest date is displayed, and the farthest dates are sequentially displayed in the same manner as (1).

Although the above embodiment is applied to a camcorder, the present invention can also be applied to a single video titler.
