Wherein the remaining accumulated value is used for an accumulated value representing a control amount that is not transmitted to the photographing apparatus.

In one embodiment, the control device does not send the control instruction to the shooting device within a preset delay time period after the user starts to rotate the dial key, the control device determines the rotation information of the dial key after the preset delay time period is rotated in response to the rotation operation of the dial key by the user, determines the input accumulated value of the control quantity of the shooting device according to the rotation information of the dial key after the preset delay time period is rotated, and takes the input accumulated value as the remaining accumulated value of the control quantity, namely, the control device does not send the control instruction to the shooting device, so that the output accumulated value of the control quantity is zero, and the input accumulated value is equivalent to the remaining accumulated value of the control quantity. The preset delay time may be set based on an actual situation, which is not specifically limited in the embodiment of the present application, for example, the preset delay time is 0.5 seconds. The control instruction is not sent to the shooting equipment within the preset delay time after the dial wheel key is rotated by the user, and meanwhile, the input value of the control quantity is accumulated, so that the influence of the user on the rotating speed of the dial wheel key is avoided when the shooting parameters of the shooting equipment are subsequently adjusted, the adjustment of the shooting parameters can be matched with the rotating operation of the user on the dial wheel key, and the user experience is greatly improved.

In one embodiment, after a user starts to rotate the dial key, in response to the rotating operation of the dial key by the user, determining an input accumulated value of a control quantity of the shooting device according to the rotating information of the dial key; when the input cumulative value is greater than or equal to a preset input cumulative value, determining an output cumulative value of the control quantity sent to the shooting device according to a control instruction sent to the shooting device in the rotation process of the thumb wheel key, and determining a remaining cumulative value of the control quantity according to the input cumulative value and the output cumulative value of the control quantity; and when the input accumulated value is smaller than the preset input accumulated value, not sending a control instruction to the shooting equipment, namely not adjusting the shooting parameters of the shooting equipment. When the input accumulated value is smaller than the preset input accumulated value, the control instruction is not sent to the shooting equipment, the change of shooting parameters caused by the fact that a user rotates a dial wheel key by mistake can be avoided, and user experience is greatly improved.

In one embodiment, in the rotating operation process of the dial wheel key by the user, when the dial wheel key is detected to stop rotating by the user, the residual accumulated value of the control quantity is set to be zero, so that after the dial wheel key stops rotating by the user, the control device does not send a control instruction to the shooting equipment any more, the adjustment of the shooting parameters can be matched with the rotating operation of the dial wheel key by the user, and the user experience is greatly improved.

In one embodiment, during a turning operation of the wheel key by the user, when a change in the turning direction of the wheel key is detected, the remaining accumulated value of the control amount is set to zero. When the rotation direction of the thumb wheel key is detected to change, the residual accumulated value is set to be zero, the influence of the residual accumulated value after the rotation direction is changed on the residual accumulated value before can be avoided, the adjustment accuracy of shooting parameters is improved, the adjustment of the shooting parameters can be matched with the rotation operation of a user on the thumb wheel key, and the user experience is greatly improved.

In one embodiment, when the change of the rotation direction of the thumb wheel key is detected, after the residual accumulated value of the control quantity is set to zero, in response to the rotation operation of the thumb wheel key by a user, the input accumulated value of the control quantity of the shooting device is determined again according to the rotation information of the thumb wheel key, and then the output accumulated value of the control quantity sent to the shooting device is determined again according to the control quantity in the control command sent to the shooting device in the rotation process of the thumb wheel key; redetermining the remaining accumulated value of the controlled variable according to the redetermined remaining accumulated value of the controlled variable and the output accumulated value; and adjusting the control quantity in the control instruction according to the redetermined residual accumulated value, and sending the adjusted control instruction to the shooting equipment.

For example, the rotation direction of the wheel key includes a clockwise direction and a counterclockwise direction, and when the rotation direction of the wheel key changes from the clockwise direction to the counterclockwise direction, the remaining accumulated value of the control amount in the clockwise direction is set to zero, and the remaining accumulated value of the control amount in the counterclockwise direction is determined; for another example, when the rotation direction of the jog dial is changed from the counterclockwise direction to the clockwise direction, the remaining accumulated value of the control amount in the counterclockwise direction is set to zero, and the remaining accumulated value of the control amount in the clockwise direction is determined.

And step S104, adjusting the size of the control quantity in the unsent control instruction according to the residual accumulated value, and sending the adjusted control instruction to the shooting equipment.

After determining the remaining accumulated value of the control amount, adjusting the control amount in the control instruction based on the remaining accumulated value of the control amount to adjust the control instruction, and transmitting the adjusted control instruction to the photographing apparatus, so that the photographing apparatus can adjust the photographing parameter of the photographing apparatus according to the control amount in the adjusted control instruction.

The user can control the shooting device to focus through the thumb wheel key, that is, the shooting device can be controlled to adjust the focus following parameter or the zoom parameter of the shooting device, the adjustment of the focus following parameter of the shooting device refers to the adjustment of the position of the focal plane of the shooting device, and the adjustment of the zoom parameter of the shooting device refers to the adjustment of the focal length of the shooting device.

In one embodiment, in the process of rotating the dial key by a user, the current position of the dial key is acquired by a position sensor at preset time intervals, and the historical position of the dial key acquired by the position sensor at the last moment is acquired; determining the current input control quantity of the dial key according to the current position and the historical position of the dial key; selecting a corresponding focusing gear from a plurality of focusing gears as a target focusing gear according to the control quantity currently input by a wheel key, wherein at least one control quantity can correspondingly select different focusing gears; and generating a focusing control instruction according to the target focusing gear, and sending the focusing control instruction to the shooting device, so that the shooting device controls the moving speed or the moving distance of the focal plane based on the control quantity in the focusing control instruction. Due to the fact that at least one control quantity can be used for correspondingly selecting different focusing gears, focusing control of the shooting equipment can be matched with operation of a user on the focusing operation component, the shooting equipment is accurately controlled to focus, and user experience is greatly improved.

The focusing gear can be used for representing the gear of the movement speed of the focal plane, and the higher the gear is, the faster the movement speed of the focal plane is, and the lower the gear is, the slower the movement speed of the focal plane is; the focusing gear can also be used for representing the gear of the change speed of the zooming parameter, the higher the gear is, the faster the change speed of the zooming parameter is, the lower the gear is, and the slower the change speed of the zooming parameter is, and the at least one control quantity refers to the currently input control quantity which is different from the control quantities corresponding to the plurality of focusing gears.

In one embodiment, there is at least one control amount capable of selecting different focus adjustment stages correspondingly, for example, the plurality of focus adjustment stages are focus adjustment stage 1, focus adjustment stage 2, focus adjustment stage 3, and focus adjustment stage 4, and the control amounts corresponding to focus adjustment stage 1, focus adjustment stage 2, focus adjustment stage 3, and focus adjustment stage 4 are 3, 5, 8, and 12, respectively, the control amount input for the first time is 6, since there is no focus adjustment stage identical to control amount 6 among the plurality of focus adjustment stages, focus adjustment stage 2 is set as the target focus adjustment stage, the control amount input for the second time is also 6, the target focus adjustment stage is still focus adjustment stage 2, the control amount input for the third time is also 6, at this time, since the control amounts output for the previous two times are both 5, the remaining control amount 2 is not output, and the control amount input for the third time is 6, the control amount not output is 8 in total, therefore, the focus shift position 3 can be set as the target focus shift position, and the control amount 2 that is not output and the control amount 6 that is input can be output. Therefore, the input control amount 6 can be selected corresponding to two different focus shift positions, that is, the focus shift position 2 and the focus shift position 3.

In one embodiment, the same control amount can correspond to different focus adjustment steps. For example, the control amounts corresponding to the focus adjustment range 1, the focus adjustment range 2, the focus adjustment range 3, and the focus adjustment range 4 are 3, 5, 8, and 12, respectively, and if the control amount input for the first time is 6, the focus adjustment range 2 is set as the target focus adjustment range, the control amount input for the second time is also 6, the target focus adjustment range is still the focus adjustment range 2, and the control amount input for the third time is 1, and at this time, since the control amounts output for the first two times are all 5, the remaining control amount 2 is not output, and if the control amount input for the third time is 3, the control amount not output is 5 in total, and therefore, the focus adjustment range 2 can be set as the target focus adjustment range, and the control amount 2 not output and the control amount 1 input can be output.

For example, the control amounts corresponding to the focus shift position 1, the focus shift position 2, the focus shift position 3, and the focus shift position 4 are 3, 5, 8, and 12, respectively, and the currently input control amount is 8, the focus shift position 3 is selected as the target focus shift position, and for example, the currently input control amount is 5, the focus shift position 2 is selected as the target focus shift position.
