Systems and methods of providing spatially dependent image exposure information to a user of a digital camera. The described approach is applicable to determination of image exposure quality in a digital camera system. In these applications an image is displayed in a first display mode wherein the exposure information is overlaid on the image or in a second display mode wherein the exposure information is eliminated or reduced and thus is less obstructive of the image. In the second display mode, a separate exposure warning optionally conveys a subset of the information displayed in the first display mode. The invention includes a user input operable to temporarily specify a change in the display of the image between the first mode and the second mode while an image is displayed, thus providing the user with direct control of the presence and duration of spatially dependent image exposure information.

The invention discloses a teaching method based on a 3D model and relates to the technical field of mechanical arm teaching. The teaching method is implemented through a teaching system. The teachingsystem comprises a teaching device, a mechanical arm and a controller, wherein the controller is arranged on the mechanical arm and used for controlling movement and operation of the mechanical arm. The teaching method based on the 3D model includes the following steps that firstly, the teaching device and the controller are connected through a network, and the teaching device displays the 3D model of the mechanical arm on a display screen of the teaching device; then the visual angle of the 3D model on the display screen is adjusted; and afterward a user coordinate system of the 3D model is built, under the user coordinate system, a moving instruction signal is sent through the teaching device, the moving instruction signal is transmitted to the controller, and thus moving of the mechanical arm is controlled directly. According to the teaching method based on the 3D model, the using difficulty of the teaching device is effectively reduced, and the teaching device is easy and convenient to use; and meanwhile, the compatibility of the teaching device is improved, and the teaching device can be applied to different models of industrial mechanical arms.

The embodiment of the invention discloses a display control method and an electronic device. After it is detected that the electronic device enters a second state from the first state, and the contents displayed by the electronic device for the first input and output area are different, whether to control the electronic device to switch from the second state to the first state based on the input information on the first input/output area is determined according to the access authority of the content displayed by the first input/output area in the first state before the electronic device entersthe second state, so that based on the display control method, a user can directly input the information on the first input and output area to control the electronic device to be switched from the second state to the first state, or the state of the electronic device can be directly controlled without inputting the information by the user, and accordingly the state switching flexibility of the electronic device is improved, and the user operation is simplified.

The embodiment of the invention provides a load equipment control method, device and system, electronic equipment and a computer storage medium. The load equipment control method comprises the steps of obtaining a control instruction; under the condition that a contact of the on-off device is closed, a wireless instruction for controlling one or more target load devices to be correspondingly turned on or turned off is sent to one or more target load devices according to the control instruction; in the process, the contact of the on-off device is always closed. The electronic equipment directly controls the load equipment according to the control instruction under the condition that the contact of the on-off device is closed, and the contact of the on-off device can be kept in a normally closed state by shielding the control function of the control instruction on closing or opening of the contact of the on-off device of the electronic equipment, so that the situation that the load equipment cannot be normally closed when the load equipment is controlled to be closed is avoided. The contact of the on-off device of the electronic equipment is disconnected, so that the load equipment is in an off-line uncontrolled state after being closed.

The invention discloses a resonance current suppression method based on synchronous detection of a current average value and an instantaneous value. A synchronous detection circuit is adopted to directly control an MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor); the synchronous detection circuit comprises a current zero crossing point detection module ZCD, a current average value detection module ACD, a signal detection module, a PWM module and a driver module. A current zero crossing point detection module ZCD is adopted to detect an inductive current instantaneous value, and a current average value detection module ACD is adopted to detect an inductive current average value; when the signal detection module receives the inductive current zero-crossing signal and the inductive current average value allowing signal at the same time, a turn-on allowing signal is sent to the PWM module; the PWM module controls the driver module to send out a driving signal, the MOSFET is turned on, and the influence of the resonance current on the input current is reduced by controlling the intermittent resonance time of the MOSFET; according to the invention, the parameter problem of the circuit does not need to be considered, the device type selection of the circuit is more flexible, the problem of input current distortion caused by resonance is fundamentally solved, and the power factor is improved.
