Embodiment
Describe embodiments of the invention with reference to the accompanying drawings in detail.
In an embodiment of the present invention, setting mobile communication terminal is that the image conversation describes with mobile phone.
Fig. 1 is the block diagram that mobile phone is used in the image conversation in the embodiment of the invention.As shown in the figure, it has following structure: camera (110) is taken subject and is obtained image; Video encoder (120) is encoded to the image that is obtained by camera (110); RF module (130) through above-mentioned video encoder (120) image encoded transfer of data to communication channel, and receive view data from communication channel; Video Decoder (140) becomes original image to the image data decoding that receives from above-mentioned RF module (130); LCD (150) shows image that obtains from above-mentioned camera (110) or the image of decoding through above-mentioned Video Decoder (140); Battery electric quantity test section (170) detects battery electric quantity; When microprocessor (160) is lower than the value of prior setting when the detected battery electric quantity of above-mentioned battery electric quantity test section (170), cut-out is from the image transmission of above-mentioned Video Decoder (140) to LCD (150), simultaneously, reduce above-mentioned video encoder (120) and carry out the image encoded frame number.
Functions such as synthetic/separation that above-mentioned RF module (130) has signal, modulation.
The work and the action effect of the embodiment of the invention are described below with reference to the workflow diagram of Fig. 2.
Generally speaking, use the number of pictures per second of video coder-decoder to be in the mobile terminal device ' 15 ' individual.The speed of 15 frame/seconds is for being more than sufficient for appreciating mobile image in the mobile terminal device.If utilize mobile terminal device to carry out the image conversation, the other side's image is with per second 15 frame decodings, and simultaneously, the image of self also is encoded as per second 15 frames.
In addition, even become half of 15 frame/seconds, i.e. 7.5 frame/seconds, the user can not experience mobile image yet mobile have significantly discontinuous.
So, under the insufficient state of the battery supply of mobile terminal device, come image is encoded a kind of waste of can saying so with per second 15 frames.
The objective of the invention is to the control of video coding decoder, make it when the battery supply charge volume is not enough, in mobile image encoding process, can reduce power consumption, even reduce the part image quality.
At first, battery electric quantity test section (170) detects the charge volume of battery and passes to microprocessor (160), and microprocessor (160) demonstrates the icon of expression battery electric quantity in view of the above on LCD (150).
Generally, if carry out the image conversation by dialing or calling, the image of user's one side that is obtained by camera (110) passes to RF module (130) through video encoder (120) so, and the image of partner one side of separating from above-mentioned RF module (130) is shown on the LCD (150) through Video Decoder (140).
Promptly, the picture signal that is obtained by camera (110) is passed to video encoder (120), above-mentioned video encoder (120) becomes per second 15 frames to image signal encoding, pass to RF module (130) then, above-mentioned RF module (130) is transferred to dialogue the other side to modulating through above-mentioned image encoded data by air traffic channel.In addition, RF module (130) in demodulation behind the transmission signals from partner, divide image data, and pass to Video Decoder (140), above-mentioned Video Decoder (140) is image data decoding per second 15 frames, is shown on the LCD (150).In fact, owing to possess video coder-decoder and audio coder-decoder, so when video coder-decoder was handled the transmission image through said process, audio coder-decoder was also realized simultaneously to the processing of transmission voice.
So the user can simultaneously see the image of partner, one side is listened voice and is conversed.
Wherein, microprocessor (160) confirms constantly whether the detected battery electric quantity of battery electric quantity test section (170) is lower than the value of prior setting in the time will carrying out the image conversation or in the image conversation is carried out.At this moment, be lower than the value of prior setting if find battery electric quantity, microprocessor (160) is control of video encoder (120) then, make it the image that obtains from camera (110) to be encoded with the speed that is lower than per second 15 frames, go back control of video decoder (140) simultaneously, make it not being presented on the LCD (150) from the partner image transmitted, thus the power consumption can reduce the image conversation time.
For example, if control of video encoder (120), the frame that makes it encoding process is reduced to 1/2 of normal condition, so, above-mentioned video encoder (120) then can be encoding behind the image of camera (110) transmission every opening deletion, so operand can be reduced to 1/2 of normal condition.That is, if the frame that video encoder (120) is handled is reduced to 1/2, power consumption also will reduce about about 50%.
And, for Video Decoder (140), though it is to decoding from the bit stream of partner transmission, but the image of decoding is not shown on the LCD (150), so, to need not in order showing, and decoded yuv data to be converted to the RGB data at above-mentioned LCD (150).In fact, YUV is about every frame about 30% to the RGB conversion at the shared proportion of Video Decoder (140).So Video Decoder (140) can on average reduce 15% power consumption by every frame.
On the other hand, the operand of video encoder (120) is more than 2 times of Video Decoder (140), and Given this, even only want above-mentioned video encoder (120) frame of encoding process to be reduced to 1/2, power savings also is sizable.
Therefore, though only being described, LCD do not show situation through the yuv data of Video Decoder (140) decoding in said process, but, the same with video encoder (120), above-mentioned Video Decoder (140) frame to be processed is reduced to 1/2, also can realizes economize on electricity.That is, Video Decoder (140) is with the given time cycle, and the frame of set number is decoded and is shown on the LCD (150), though not continuous mobile image, but still can see that the image of partner carries out the image conversation.
In addition, when carrying out the image conversation, detect battery electric quantity for economize on electricity, detecting the required set value of battery electric quantity can freely be determined by the user.At this moment, because generally can't correctly understanding operation energy-saving mode (power save mode), the user needs how many electric weight, so can be provided with in advance by mobile terminal device manufacturer.
And video encoder (120) and Video Decoder (140) frame number to be processed can freely be determined by the user, also can be determined in advance by terminating machine manufacturer.
The as above detailed description of being done, the present invention are passed through under the situation of terminating machine power supply deficiency, video coder-decoder frame to be processed when reducing the image conversation, thus have the effect that can prevent because of the excessive power consumption of work of video coder-decoder.
