A method for taking photo with an extension flash module of a mobile device is provided in the present invention. The mobile device operates in coordination with an extension flash module to achieve fill light while taking photo. The method includes the following steps: detecting a specific event before a flashable period. The flashable period starts from the time at which a last row of photo sensors begins exposure to the time at which a first row of photo sensors ends exposure. The time at which the specific event occurs is a fixed period of time compared to the flashable time. Then, triggering a flash instruction according to a flash delay time and a period from the time at which the specific event occurs to the flashable time, such that the extension flash module flashes during the flashable time.

Method for taking photo with extension flash module of mobile device

The present invention discloses a method for controlling flash timing of an extension flash module cooperating with a mobile device to provide supplemental light. The method includes: detecting a specific event before a flashable time period, wherein the flashable time is a period from the time at which a last photo sensor row of a specific frame begins exposure to the time at which a first photo sensor row in the specific frame ends exposure, wherein the time period from when the specific event occurs to a flashable time in the flashable time period has a fixed length of time; and triggering a flash instruction after a delay time from when the specific event occurs, such that the flash timing of the extension flash module is in the flashable time period.

A parameter control method for an integrated circuit and an integrated circuit using the same are provided. The method includes the steps of: providing a correspondence between 1to Nimpedance groups and 1to Nfirst settings, wherein each impedance group includes K sub impedances; providing a correspondence between 1to Ksub-impedance and 1to Ksecond settings; detecting an impedance from a specific pin of the integrated circuit; comparing an impedance detected from the specific pin of the integrated circuit with the 1st to Nimpedance sets to find a corresponding specific impedance set to select a specific first setting; comparing the impedance detected from the specific pin of the integrated circuit with the 1to Ksub-impedance of the specific impedance set to select a specific second setting; and operating the integrated circuit according to the specific first setting and the specific second setting.

Parameter control method for integrated circuit and integrated circuit using the same

An extension flash module is provided in the present invention. The extension flash module adopts xenon flash light and is for attaching on the headphone jack of a mobile device. When the extension flash module operates, the voltage output from the headphone connector is boosted to provide a high voltage to the extension flash module. When the high voltage is charged to a rate voltage, the extension flash module sends a charging complete signal to the mobile device through the microphone terminal of the headphone connector. When shutter instruction is performed, the mobile device triggers the extension flash module to flash.
