Embodiments of this application provide a time display method and an electronic device. The method is applied to an electronic device with a display, and the method includes: The electronic device obtains a first image, a second image, and a third image, where the first image includes a first part of a target control, the second image includes a second part of the target control, and the third image includes a digital clock. The electronic device sequentially superimposes the first image, the third image, and the second image to generate a to-be-displayed image, where the first part and the second part of the target control form the target control, and the target control overlaps at least one digit of the digital clock. The electronic device displays the to-be-displayed image when the display is in an always-on-display state.

Smart watches and associated systems and methods thereof for lock-screen management are disclosed. A smart watch includes a heart rate sensor, and a method for lock-screen management of the smart watch includes: reading, by the heart rate sensor, a heart rate; determining based on the heart rate whether the smart watch has been taken off by the user, and if yes, stopping the heart rate sensor from working and entering by the smart watch a password-lock-screen mode. Thus, using the method according to the present disclosure can improve the information security on the smart watch.

A digital display mechanism for the alphanumeric segment display of an integer magnitude whose instantaneous value is defined by an output of a timepiece movement, including a continuous display support guided along a particular trajectory by a guide device and driven in at least one direction of travel by a drive device, including at least a first display surface and a second display surface which are different from each other, each first surface or second surface forming only one part of an alphanumeric symbol, numeral or letter, and arranged to be visible to a user of the timepiece, each continuous display support being either a serrated belt driven by a serrated pinion complementary to the serration of the belt, or a chain driven by a pinion complementary to the articulation of the links of this chain.

The present invention is to reduce an increase in a processing load when a background image is displayed in addition to pointer images indicating pointer movements. A control section displays a plurality of pointer images indicating pointer movements in a timepiece display area of a display section based on time information acquired from a clock circuit. Here, the control section identifies an area where the plurality of pointer images are displayed, such as a pointer movement area or a pointer presence area in the pointer movement area, and controls to perform high-load and low-load display operations with different processing loads on the identified area and an area other than the identified area, such as an outer area outside the pointer movement area or a pointer absence area in the pointer movement area, respectively.

An electronic timepiece includes a display section capable of displaying reception state information based on the strength of a received satellite signal or the number of captured satellites during the execution of a reception process. In a case where a predetermined period has elapsed with no acquisition of time information or position information since the reception process started, the reception state information is displayed on the display section, and in a case where the time information or the position information has been successfully acquired within the predetermined period since the reception process started, the reception state information is not displayed on the display section but the reception process is terminated.

A sequential displaying method is provided. The method includes providing a display device which includes a first display area. The first display area has N first sub-areas that are arranged in sequence, wherein N is positive integer. Then, displayed images in the N first sub-areas are sequentially updated, wherein a time interval of updating the displayed images in two adjacent first sub-areas is 60/N seconds and a frequency for updating a displayed image in each of the first sub-areas is once every 60 seconds. Thus, a method for displaying time information could be improved.

Smart watches and associated systems and methods thereof for lock-screen management are disclosed. A smart watch includes a heart rate sensor, and a method for lock-screen management of the smart watch includes: reading, by the heart rate sensor, a heart rate; determining based on the heart rate whether the smart watch has been taken off by the user, and if yes, stopping the heart rate sensor from working and entering by the smart watch a password-lock-screen mode. Thus, using the method according to the present disclosure can improve the information security on the smart watch.

An information display method includes recognizing a position relationship between a dial and an indicating hand from an image in which an electronic timepiece having a dial and an indicating hand for indicating the dial is included as an imaged subject, specifying a value corresponding to the position relationship, based on specification information of the electronic timepiece, and displaying an annotation image relating to the specified value along with the image.
