Method, apparatus, device, and product for determining smoothness

An electronic device, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory having instructions stored therein, the instructions, when executed by the processor, causing the electronic device to:
• determine a first frame number of drawn frames and a dropped frame number for dropped frames associated with a user interface (UI) within a preset time period;
• determine a second frame number of frames that should be drawn within the preset time period based on a duration of the preset time period and a preset UI refresh rate;
• determine a drawing percent for indicating weights of the drawn frames and the dropped frames based on the first frame number, the dropped frame number, and the second frame number;
• and
• determine smoothness of the UI based on the first frame number, the dropped frame number, and the drawing percent.

The electronic device according 10, wherein the instructions causing the electronic device to determine the first frame number of drawn frames for the UI and the dropped frame number for the dropped frames within the preset time period further cause the electronic device to:

• for a drawn frame within the preset time period, obtain a drawing duration;
• for the drawn frame within the preset time period, determine whether the drawing duration satisfies a preset condition associated with the UI refresh rate;
• determine, in response to the drawing duration not satisfying the preset condition, that a corresponding dropped frame exists for the drawn frame that do not satisfy the preset condition;
• and
• determine the dropped frame number for the dropped frames based on the dropped frame.

The electronic device according 11, wherein the instructions causing the electronic device to determine whether the drawing duration satisfies the preset condition associated with the UI refresh rate further cause the electronic device to:

• determine a threshold for the drawing duration based on the UI refresh rate;
• determine whether the drawing duration is less than or equal to the threshold;
• determine, in response to the drawing duration being less than or equal to the threshold, that the drawing duration satisfies the preset condition;
• and
• determine, in response to the drawing duration being greater than the threshold, that the drawing duration does not satisfy the preset condition.

The electronic device according 14, wherein the instructions causing the electronic device to determine the smoothness of the UI further cause the electronic device to:

• determine a first frames per second (fps) during a drawing period of the drawn frames based on the first frame number and the dropped frame number;
• determine a second fps of the preset time period based on the first fps and the drawing percent;
• and
• determine the smoothness of the UI based on the second fps.

A non-transitory computer-readable storage medium having computer-executable instructions stored thereon, wherein the computer-executable instructions, when executed by a processor, cause the processor to:

• determine a first frame number of drawn frames and a dropped frame number for dropped frames associated with a user interface (UI) within a preset time period;
• determine a second frame number of frames that should be drawn within the preset time period based on a duration of the preset time period and a preset UI refresh rate;
• determine a drawing percent for indicating weights of the drawn frames and the dropped frames based on the first frame number, the dropped frame number, and the second frame number;
• and
• determine smoothness of the UI based on the first frame number, the dropped frame number, and the drawing percent.

The non-transitory computer readable storage medium according 19, wherein the instructions causing processor to determine the first frame number of drawn frames for the UI and the dropped frame number for the dropped frames within the preset time period further cause the processor to:

• for a drawn frame within the preset time period, obtain a drawing duration;
• for the drawn frame within the preset time period, determine whether the drawing duration satisfies a preset condition associated with the UI refresh rate;
• determine, in response to the drawing duration not satisfying the preset condition, that a corresponding dropped frame exists for the drawn frame that do not satisfy the preset condition;
• and
• determine the dropped frame number for the dropped frames based on the dropped frame.
