Abstract

The present disclosure relates to a method and a device for setting a shooting parameter. The method includes displaying a digital color temperature adjusting key and at least one scenario color temperature adjusting key in a menu bar on the touch screen, receiving a tapping signal on a digital color temperature adjusting key displayed on a touch screen, displaying a scrolling list according to the tapping signal. A first set of n color temperature values are displayed in the scrolling list and one color temperature value in the n color temperature values is in an active state. The method further includes receiving a scrolling signal associated with the scrolling list, scrolling the first set of n color temperature values to display a second set of n color temperature values in the scrolling list in response to the scrolling signal, and selecting as the shooting parameter a color temperature value which is in an active state. The present disclosure may solve the problem that the number of scenario adjusting modes is limited and a user is not able to adjust the color temperature values of all the scenarios.

receiving a scrolling signal associated with the scrolling list;

scrolling the first set of n color temperature values to display a second set of n color temperature values in the scrolling list in response to the scrolling signal; and

selecting as the shooting parameter a color temperature value which is in an active state among the second set of n color temperature values, wherein based on the selected color temperature value, dynamically adjusting an image displayed on the touch screen,

wherein the method further comprising;

receiving a tapping signal triggered on one of the at least one scenario color temperature adjusting key; and

selecting as the shooting parameter a preset color temperature value corresponding to environment light of the one of the at least one scenario color temperature adjusting key,

wherein the displaying the scrolling list according to the tapping signal comprises;

hiding the digital color temperature adjusting key and all of the at least one scenario color temperature adjusting key from the touch screen, and displaying the scrolling list in a display region obtained after the hiding, and

based on a location of the digital color temperature adjusting key on the screen, extending a display region for the scrolling list towards a predetermined direction, and displaying the scrolling list in the display region.

2. The method according to claim 1, further comprising:

displaying a white balance adjusting key in the menu bar;

receiving a selecting signal triggered on the white balance adjusting key;

when the selecting signal indicates a manual adjusting manner, displaying the digital color temperature adjusting key and at least one scenario color temperature adjusting key in the menu bar on the touch screen; and

when the selecting signal indicates an automatic adjusting manner, selecting as the shooting parameter a color temperature value of environment light of an environment where the device locates by a sensor.

3. The method according to claim 1, wherein

scrolling the first set of n color temperature values to display a second set of n color temperature values in the scrolling list comprises:

obtaining a scrolling direction and a scrolling speed of the scrolling signal;

scrolling the first set of n color temperature values based on the scrolling direction and the scrolling speed, and reducing the scrolling speed as the scrolling proceeds, wherein when a color temperature value scrolls into a predetermined region in the scrolling list, the color temperature value is in the active state, and when a color temperature value has not arrived at the predetermined region in the scrolling list or has scrolled outside the predetermined region in the scrolling list, the color temperature value is in an inactive state; and

when the scrolling speed is smaller than a predetermined threshold, determining one color temperature value displayed in the predetermined region as the shooting parameter.

4. The method according to claim 3, further comprising:

when a color temperature value changes from the inactive state to the active state, distinguishingly displaying digits of the color temperature value; and

when a color temperature value changes from the active state to the inactive state, normally displaying digits of the color temperature value.

5. A device for setting a shooting parameter, comprising:

a processor; and

a memory for storing instructions executable by the processor, wherein the processor is configured to perform;

displaying a digital color temperature adjusting key and at least one scenario color temperature adjusting key in a menu bar on a touch screen;

receiving a signal associated with tapping on the digital color temperature adjusting key displayed on a touch screen;

displaying a scrolling list in response to the signal associated with tapping, wherein a first set of n color temperature values are displayed in the scrolling list and one color temperature value in the first set of n color temperature values is in an active state;

receiving a signal associated with scrolling on the scrolling list; and

scrolling the first set of n color temperature values to display a second set of n color temperature values in the scrolling list in response to the scrolling signal; and

selecting as the shooting parameter a color temperature value which is in an active state among the second set of n color temperature values, wherein based on the selected color temperature value, dynamically adjusting an image displayed on the touch screen,

wherein the processor is further configured to perform;
