Abstract

The invention provides an OSD time display method based on display edge indication, which comprises the following steps: step S1: the upper, lower, left and right four side areas of the screen draw 3 incompletely overlapped concentric boxes: the outer frame, the middle frame and the inner frame; step S2: the inner frame is used for separating the middle frame from the signal source picture; step S3: when the middle frame is used as the minute indication frame for second indication; the moving angle of the second hand is 6 degrees each time, the center of the screen is taken as the center of a circle, the center of the circle is assumed to be vertically upward to be 0 degree, the middle frame and the outer frame are cut every 6 degrees from the center of the circle to the outside, and 60 sections of the cut middle frame and the cut outer frame are respectively arranged; counting from the right top of the center of the screen, wherein the Mth section of the middle frame represents the Mth minute, and the Sth section of the outer frame represents the Sth second; step S4: when the middle frame is used as the clock and the outer frame is used as the minute indication, the step S3 is performed. The invention has more beautiful display effect and can not block key areas on the picture.

Description

OSD time displaying method based on display edge indication

Technical Field

The invention belongs to the field of display control, and particularly relates to an OSD time displaying method based on display edge indication.

Background

On the screen, a digital type clock or timer is displayed using OSD. The clock has two types of countdown and current time. The OSD timer or clock uses a semitransparent mode to display, so as to avoid completely blocking the picture of the signal source. However, the clock is displayed on the screen, and the picture clock of the signal source is displayed in a semi-transparent mode, if the clock is too transparent, the clock cannot be seen clearly, and if the clock is more opaque, the picture of the signal source cannot be seen clearly.

The area with the width of about 3 pixels on the upper, lower, left and right sides of the screen is usually beautiful, some space is reserved, important characters cannot be displayed, even if the number of pictures or characters is less than 3 pixels, the pictures or characters can be pieced together approximately, and therefore the OSD message is displayed by using the area, and the operation of a user is hardly influenced.

Disclosure of Invention

The invention aims to provide an OSD display time method based on display edge indication, which is a display with a clock or timing (including counting down and how long is passed) function.

The invention adopts the following technical scheme: an OSD display time method based on display edge indication is characterized in that: the method comprises the following steps: step S1: drawing 3 incompletely overlapped concentric frames in four side areas of the upper side, the lower side, the left side and the right side of the screen, and respectively naming the frames as an outer frame, a middle frame and an inner frame from outside to inside; step S2: the inner frame is used for separating the middle frame from the signal source picture so as to avoid the phenomenon that the color of the middle frame is similar to that of the PC picture and cannot be identified; the middle frame and the outer frame are respectively used as the indication of minutes and seconds or used as the indication of a clock and minutes; step S3: when the middle frame is used as the minute indication frame for second indication; the moving angle of the second hand is 6 degrees each time, the center of the screen is taken as the center of a circle, the center of the circle is assumed to be vertically upward to be 0 degree, the middle frame and the outer frame are cut every 6 degrees from the center of the circle to the outside, and 60 sections of the cut middle frame and the cut outer frame are respectively arranged; counting from the right top of the center of the screen, wherein the Mth section of the middle frame represents the Mth minute, and the Sth section of the outer frame represents the Sth second; step S4: when the middle frame is used as a clock to indicate that the outer frame is used as a minute indicator, the moving angle of the minute hand is 6 degrees each time, the center of the screen is used as the center of a circle, the center of the circle is assumed to be vertically upward to be 0 degree, the middle frame and the outer frame are cut every 6 degrees from the center of the circle to the outside, and 60 sections of the cut middle frame and the cut outer frame are respectively arranged; the number of the middle frame is counted from the position right above the center of the screen, the mth section of the middle frame represents the mth, and the mth section of the outer frame represents the mth score.

Further, when the middle frame is used as a minute indication frame for second indication, the upper side, the lower side, the left side and the right side of the screen select an area with the width of about 3 pixels; when the middle frame is used as a clock indication outer frame as a minute indication, the area with the width of about 4 pixels is selected on four sides of the upper, lower, left and right sides of the screen.

Compared with the prior art, the invention takes the upper, lower, left and right edges of the display panel as the time indication areas of the square clock or the timer, the display effect is more beautiful, and the key areas on the picture can not be blocked.

Detailed Description

The invention is further explained below with reference to the figures and the specific embodiments.

An OSD display time method based on display edge indication is characterized in that: the method comprises the following steps:

step S1: drawing 3 incompletely overlapped concentric frames in four side areas of the upper side, the lower side, the left side and the right side of the screen, and respectively naming the frames as an outer frame, a middle frame and an inner frame from outside to inside; as shown in fig. 1.

Step S2: the inner frame is used for separating the middle frame from a signal source picture (hereinafter referred to as a PC picture) to avoid the phenomenon that the color of the middle frame is similar to that of the PC picture and cannot be identified; the middle frame and the outer frame are respectively used as the indication of minutes and seconds or used as the indication of a clock and minutes;

step S3: when the middle frame is used as the minute indication frame for second indication; the moving angle of the second hand is 360/60=6 degrees each time, the center of the screen is taken as the center of a circle, the center of the circle is assumed to be vertically upward to be 0 degree, the middle frame and the outer frame are cut every 6 degrees from the center of the circle to the outside, and 60 sections of the cut middle frame and the cut outer frame are respectively arranged; as shown in fig. 2. Counting from the right top of the center of the screen, wherein the Mth section of the middle frame represents the Mth minute, and the Sth section of the outer frame represents the Sth second; as shown in fig. 3 minutes and 15 seconds.

Step S4: when the middle frame is used as a clock to indicate that the outer frame is used as a minute indicator, the moving angle of the minute hand is 6 degrees each time, the center of the screen is used as the center of a circle, the center of the circle is assumed to be vertically upward to be 0 degree, the middle frame and the outer frame are cut every 6 degrees from the center of the circle to the outside, and 60 sections of the cut middle frame and the cut outer frame are respectively arranged; the number of the middle frame is counted from the position right above the center of the screen, the mth section of the middle frame represents the mth, and the mth section of the outer frame represents the mth score.

The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
