Furthermore, the terms "first," "second," and "third," etc. are used to distinguish between different objects and are not used to describe a particular order.

In the embodiment of the invention, the shooting terminal can monitor the current color temperature value of the shooting environment where the shot object is located through the color temperature sensor. In particular, the shooting terminal can monitor the current color temperature value of the shooting environment where the shooting object is located through the color temperature sensor in the pre-flashing stage of the flash lamp of the shooting terminal. Because the flash lamp of the shooting terminal can be pre-flashed and then mainly flashed when the flash lamp is started for shooting, the practice finds that the shooting terminal can detect the current color temperature value of the shooting environment where the shot object is located through the color temperature sensor at the pre-flashing stage of the flash lamp of the shooting terminal.

It can be seen that, in the technical scheme of this embodiment, by monitoring the current light intensity value and the current color temperature value of the shooting environment and adjusting the light intensity value and the color temperature value of the flash lamp used for shooting by the camera according to the monitored current light intensity value and the monitored current color temperature value of the shooting environment, test practices find that, because the influence of the light intensity and the color temperature on shooting is considered at the same time, the probability of the shot photo with explosion is favorably reduced and the quality of the shot photo is improved by adaptively adjusting the light intensity value, the color temperature value and the like of the flash lamp used for shooting by the camera.

Optionally, in some possible embodiments of the present invention, adjusting a color temperature value of a flash used for shooting by a camera according to the obtained color temperature adjustment value includes: inquiring a target current value matched with the color temperature regulating value from a prestored matching table of the current value and the color temperature value, wherein the target current value comprises a target current value of a high-color-temperature light-emitting diode and a target current value of a low-color-temperature light-emitting diode; and adjusting the current value of the high-color-temperature light-emitting diode of the flash lamp used for shooting by the camera to the inquired target current value of the high-color-temperature light-emitting diode, and adjusting the current value of the low-color-temperature light-emitting diode of the flash lamp used for shooting by the camera to the inquired target current value of the low-color-temperature light-emitting diode, so as to adjust the color temperature value of the flash lamp used for shooting by the camera.

For example, a matching table of current values and color temperature values may be preset in the shooting terminal according to empirical values or test data, and each color temperature value in the matching table may be matched with a high color temperature led current value and a low color temperature led current value at the same time. When the color temperature values are different, the current values of the high-color-temperature light-emitting diodes matched with the color temperature values are different, and the current values of the low-color-temperature light-emitting diodes matched with the color temperature values are also different.

Referring to fig. 2-a, fig. 2-a is a schematic flow chart of a shooting parameter adjustment method according to another embodiment of the present invention, as shown in fig. 2-a by way of example, a shooting parameter adjustment method according to another embodiment of the present invention may include:

One possible representation of the color temperature matching table may be shown, for example, in fig. 2-c.

208. And the shooting terminal adjusts the color temperature value of a flash lamp used by the camera for shooting according to the acquired color temperature adjusting value.

For example, a matching table of current values and color temperature values may be preset in the shooting terminal according to empirical values or test data, and each color temperature value in the matching table may be matched with a high color temperature led current value and a low color temperature led current value at the same time.

For example, if the color temperature adjustment value is 3429 and the current color temperature value of the flash is 3190, the terminal can compare that the target color temperature value 3429 is higher than the current color temperature value 3190, and then the terminal can adjust the current of the high color temperature led of the flash turned on by the terminal to 0.1mA to 0.2mA, and adjust the current of the low color temperature led of the flash to 0.9mA to 0.8 mA.
