AI Technical Summary

Problems solved by technology

[0004] Most of the current mobile terminals use the camera module as a CMOS sensor, but the lighting time of the xenon flash is very short, about 1 / 25000 seconds (0.04 milliseconds) to 0.2 milliseconds, which is shorter than the time for general CMOS sensors to collect light from the beginning to the end
And because present portable shooting devices (such as mobile phones, tablet computers, etc.) use multitasking processors, the operating systems they run are mostly multitasking operating systems, and multiple processing processes are waiting to be processed at the same time, so it is difficult to Synchronize the shooting instruction with the flash instruction
[0005] And because the flash time of the xenon flash is very short (about 40 microseconds to 0.2 milliseconds), if the shooting command and the flash command of the xenon lamp cannot be executed synchronously, it is difficult for the camera module to use the flash generated by the xenon flash, that is, the flash generated by the xenon flash The flash is basically useless for taking pictures, and you can't get good shooting results

[0065] First embodiment: the shooting start command includes synchronization time, and the parameter acquisition module directly obtains the synchronization time from the shooting start command; the flash start command includes flash parameters, and the parameter acquisition module directly obtains the flash parameters from the flash start command.

no. 2 example

[0066] Second embodiment: the shooting start command does not include the synchronization time, and the flash start command does not include flash parameters. The camera flash control device stores a synchronization time correspondence table and a flash parameter correspondence table. The parameter acquisition module inquires the synchronization time correspondence table according to the shooting parameters to obtain the synchronization time corresponding to the shooting parameters, and obtains the shooting parameters by querying the flash parameter correspondence table according to the shooting parameters. parameter corresponds to the flash parameter.

[0067] In a preferred aspect of this embodiment, the command receiving module is further configured to receive the focus / environment light metering command. The camera flash control device also includes a focus metering control module, which is used to send the focus / environment metering command to the camera module 200, recei...

Abstract

The invention provides a portable camera device comprising a camera module, a central processing unit, an xenon flash lamp module and a control unit, wherein the control unit is in data transmission connection with the central processing unit, the camera module and the xenon flash lamp module; the central processing unit obtains a shooting parameter, generates a shooting startup instruction and aflickering startup instruction, the shooting startup instruction comprises the shooting parameter, the central processing unit sends the shooting startup instruction and the flickering startup instruction to the control unit, and the control unit controls the camera module to perform shooting and control the xenon flash lamp module to flicker when receiving the shooting startup instruction and theflickering startup instruction transmitted by the central processing unit. The invention further provides a camera flickering control device. By adoption of the technical scheme of the invention, theshooting effect of the portable camera device can be improved.

Description

technical field [0001] The present invention relates to the field of portable electronic devices, in particular, to the field of photography of portable electronic devices. Background technique [0002] At present, most of the mobile camera devices on the market (such as mobile phones, tablet computers and other portable camera devices) are equipped with LED fill light, and LED fill light is difficult to achieve due to the limited light brightness when the light is insufficient or the camera is far away. Ideal fill light effect. [0003] Xenon flash lamps, also known as high-intensity discharge gas lamps, can achieve flashes that far exceed the brightness of LED flash lamps, and have excellent daylight reduction capabilities. The use of xenon flash can better take high-quality photos, especially when the shooting distance is relatively long or the light is weak, the effect is more obvious. Therefore, some professional photographic equipment (such as SLR cameras) are equipp...
