After the user sets the interval value, the interval value is adjusted by using the value set by the user, namely, the caption interval adjustment value is set as the user-defined interval value.
Step 102: judging whether each adjacent caption assembly meets the caption space condition according to the dot matrix information of each caption assembly and the caption space adjustment value; the dot matrix information of each subtitle component is obtained by carrying out data dot matrix conversion on each subtitle component.
In this embodiment, as shown in fig. 2, the word spacing in fig. 2 is a subtitle spacing adjustment value, the subtitle spacing adjustment value may be defined by a user or determined according to a default value (the word spacing of the subtitle component), when the component distance value of the subtitle component is smaller than the word spacing, a transparent frame is added, and when the component distance value of the subtitle component is not smaller than the word spacing, the frame of the subtitle component is cut.
Optionally, the dot matrix information of each caption component is obtained by performing data dot matrix conversion on each caption component, which specifically includes:

if the subtitle space is lower than the subtitle space, the subtitle space condition is satisfied;
if not, the subtitle space condition is not satisfied.
In this embodiment, according to the dot matrix positioning information of the last word of the first subtitle component and the dot matrix positioning information of the first word of the second subtitle component, it is determined whether the space between the subtitle components is lower than the subtitle space adjustment value (the first subtitle component word space/the user-defined space value), that is, whether the current component distance value is lower than the subtitle space adjustment value.

Optionally, according to the current frame selection information and the subtitle interval adjustment value of the adjacent subtitle components, setting frame selection information of the transparent frame selection, specifically:
obtaining the height of the transparent selection frame according to the current height of the first subtitle component;
and subtracting the current component distance value from the subtitle interval adjustment value to obtain the width of the transparent selection frame.
In this embodiment, when the current component distance value x2 is smaller than the subtitle space adjustment value x1 and is lower than the subtitle space adjustment value, the transparent frame selection height is based on the height of the first subtitle component drawn by the user at the beginning, the transparent frame selection length (width) is the distance between words calculated by the upper computer when the first subtitle is converted into dot matrix data, the word space of the first subtitle component is obtained, the distance between the last word of the first subtitle component and the first word of the second subtitle component is the current component distance value x2, when the subtitle space adjustment value x1 is the word space of the first subtitle component, the length (width) of the transparent frame selection is the length (width) of x1-x2, and when the subtitle space adjustment value x1 is the user-defined space value, the length (width) of the transparent frame selection is the length (width) of x1-x 2. When the user has a self-defined distance, the frame selection length is issued for the length set by the user, so that only the middle transparent frame selection is modified, the time for reconstructing the caption text information dot matrix is reduced, and a satisfactory display effect is achieved.
