Embodiment
With reference to the accompanying drawings, describe embodiments of the invention in detail.
Fig. 1 is that the camera that is used for mobile communication terminal of the present invention constitutes block diagram.As shown in the figure, it is made of following several sections: camera sensor 10, and it takes things, output image according to the shutter speed of adjusting under image processing part 20 controls; Image processing part 20, many images that it is taken camera sensor 10 under equal angular continuously are stored in frame buffer 40, calculate the average image of the image of storage, and notifying communication terminal 30 is taken and is finished; Communication terminal 30, it from image processing part 20 receive take the notice finish after, output is taken and is finished sound, and the average image of storage in the frame buffer 40 is outputed in the screen as final photographic images; Frame buffer 40.
Image processing part 20 is adjusted shutter speed after the user presses the shooting button, drives camera transducer 10 obtains the image that camera sensor 10 is taken.Image processing part 20 is stored in frame buffer 40 take many images that obtain continuously under equal angular.The average image of the image of storage and storage in the image processing part 20 computed image buffers 40, notifying communication terminal 30 is taken and is finished.Many images of storage in the image processing part 20 deleted image buffers 40.
Camera sensor 10 is taken things according to the shutter speed of adjusting under the control of image processing part 20, and passes to image processing part 20.Frame buffer 40 is stored in interior many images of being taken by camera sensor 10 of shooting time of image processing part 20.
Communication terminal 30 from image processing part 20 receive take the notice finish after, output is taken and is finished sound, and the average image of storage in the frame buffer 40 is output as final photographic images in screen.
Fig. 2 is the action flow chart of the method for improving photographic picture quality in the mobile communication terminal of band camera of the embodiment of the invention.As shown in the figure, it comprises following several steps: communication terminal 30 detects takes pressing of button, the step that order image processing part 20 is taken; Image processing part 20 is adjusted the image taking number of times pro rata with the shutter speed that the user selects, drives camera transducer 10 is taken continuously, judge whether many images that camera sensor 10 is taken are images of taking, many images of taking under equal angular are stored in the step of frame buffer 40 under equal angular; Image processing part 20 calculates the average image of many images and is stored in frame buffer 40, and notifying communication terminal 30 is taken the step of finishing; Communication terminal 30 is received the notice that image processing part 20 is finished about shooting, and the average image of storage is output as final photographic images in the reading images buffer 40 in screen, and the step of finishing sound is taken in output simultaneously.
Suppose that the user selects the camera menu, presses the shooting button under exposal model.
Communication terminal 30 detects takes pressing of button, and order image processing part 20 is taken.Image processing part 20 is adjusted the image taking number of times pro rata with the shutter speed that the user selects, drives camera transducer 10 is taken continuously, judge whether many images that camera sensor 10 is taken are images of taking, and many images of taking are stored in frame buffer 40 under equal angular under equal angular.At this moment, image processing part 20 is not being that the image of taking under equal angular is stored in frame buffer 40.
If shutter speed is very fast, the image taking number of times in given time increases so, and on the contrary, if shutter speed is slack-off, then the image taking number of times in the given time reduces.Therefore, image processing part 20 is adjusted the image taking number of times pro rata with shutter speed, adjusts the continuous shooting number of times in the given time.
