Fig. 3 is the touch screen diasonograph that the present invention relates to, and carries out the flow chart of detected image movie under its frozen state, and concrete performing step is following:
Step 1: beginning;
Step 2: whether on image have message instruction, if having, get into step 3 if judging, otherwise get into step 10;
Step 3: judge whether the contact produces displacement message on image, if get into step 4, otherwise get into step 10;
Step 4: judged whether release message, if get into step 5, otherwise get into step 3;
Step 5: make comparisons according to velocity information in the displacement message and the speed of presetting,, get into step 6, otherwise get into step 11 if less than the speed of presetting;
Step 6: get into the single frames play mode;
Step 7: judge the positive and negative of speed according to presetting velocity information,, otherwise get into step 9 if positive speed gets into step 8;
Step 8: played in order;
Step 9: backward is play;
Step 10: according to current contact position calculation present image frame number, and display image, after finishing once to play, get into step 2 and rejudge;
Step 11: get into the movie pattern;
Step 12: according to presetting threshold speed decision movie speed and movie;
Step 13: whether on image have message instruction, if having, get into step 14 if judging, otherwise get into step 16;
Step 14: suspend and play, show current frame image;
Step 15: the message instruction is arranged once more,, get into step 2 and rejudge from the present frame movie;
Step 16: continue movie, get into step 2 and rejudge.
At first get into freezing mode, in step 2, judge whether the message instruction is arranged on image, this message can be sent the message instruction through direct or indirect mode to touch screen on ultrasonoscopy, if having, get into step 3, otherwise gets into step 10; In step 3, when the message instruction is arranged on the image, further judge whether to produce displacement message, if get into step 4, otherwise get into step 10; In step 4, judged whether that further release message produces, if having, get into step 5, otherwise get into step 3, whether rejudge has new displacement message to produce; In step 5; Compare according to velocity information in the displacement message and the speed of presetting; Here need to prove; Velocity information in the displacement message comprises the average speed that produces this displacement message, acceleration, displacement starting velocity, displacement termination speed etc., and all velocity informations relevant with displacement all can be used as the speed of presetting.If present speed less than the speed of presetting, gets into the single frames play mode, the doctor can check image by a frame one frame sequential, if present speed greater than the speed of presetting, gets into the movie pattern; In step 6, doctor's single frames is checked image; In step 7, after the entering single frames is play, judge velocity attitude according to the velocity information that presets; Internal system can self-defined speed positive negative direction, when the user gave displacement message of touch screen through direct or indirect mode, the velocity attitude that produces this displacement can be judged according to the instruction that receives by system; If velocity attitude is consistent with the forward direction speed direction that presets; Then get into step 8, otherwise get into step 9, need to prove here; Because manual operation can not guarantee when producing displacement; The direction of displacement is an abswolute level, is left or operation to the right so the positive negative direction that system can be at an angle as the demarcation line of defining the displacement left and right directions, is judged in the certain angle scope; Spend such as being defined in negative 90 that arbitrarily angled slip all is judged to be operation to the right between positive 90 degree, spend to arbitrarily angled slide deciding between 270 degree for operating left 90.Wherein the corresponding relation of direction of displacement and positive-negative velocity direction is set according to system is self-defined; In step 8, the frame number of image increases, the order of representation playing image; In step 9, the frame number of image reduces, expression reverse play film; In step 10; Frame number according to current contact position calculation present image; And display image; Here the contact is meant with direct or indirect mode (including but not limited to operation such as slide, click, drag with modes such as finger, felt pen, radio, infrared ray, electromagnetic induction) and sends the message instruction to touch screen, and corresponding position information was defined as the contact when touch screen was made response to this instruction, include but are not limited to object directly the mode of contact touch screen is operated.Suppose that the present image frame number is N, when displacement message produces and is judged to be direct velocity direction, calculate frame number side-play amount M according to the displacement size; Then the present image frame number is (N+M); When displacement message produced and is judged to be the negative velocity direction, then the present image frame number was (N-M), when calculating the frame number of present image; Can calculate the data address of present image automatically according to the big mini system of every two field picture, from the film memory block, read view data then and deliver to display screen and show.After a single frames play operation finishes, get into step 2 and continue to have judged whether that the message instruction produces; In step 11, get into the movie pattern; In step 12; Confirm movie speed according to the threshold speed that presets; Internal system is divided through the speed of presetting the speed that gets into the movie pattern once more; Such as can movie speed being divided into several speed thresholds, like quick broadcast, at the uniform velocity broadcast, slow play etc., concrete movie speed is divided the not special restriction of number of class.In step 13, judged whether the message instruction, if during movie; Send message with direct or indirect mode to touch screen, then get into step 14, instruction here is meant the instruction of sending touch screen message with direct or indirect mode to touch screen; If do not have the message instruction, get into step 16; In step 14, suspend current in progress film, show current frame image; In step 15, when film is in halted state, when message instruction touch screen is arranged once more,, then begin to continue movie from present frame such as clicking; In step 16,, then continue movie if there is not pausing operation.No matter be after a movie end or single-frame images are play end, all to get into step 2, judge whether that new touch screen message produces, and then the continuation judgement is that single frames is play or continuous the broadcast.
In the concrete embodiment of Fig. 3, the doctor is in the process to patient's diagnosis, in the time of need watching film image to play; At first get into freezing mode; At this moment the doctor can be on ultrasonoscopy sends message through direct or indirect mode to touch screen and realizes movie, this operation directly act on image originally on one's body, rather than carry out the menu mode adjusting in the exterior lateral area of display image; When message is instructed after producing displacement on the touch screen and discharging; System compares according to velocity information in the displacement message and the speed of presetting, and confirms that it still is continuous movie that single frames is play, if present speed is less than the speed of presetting one; Get into the single frames play mode, the doctor can check image by a frame one frame sequential.The direction of displacement that system produces on touch screen according to the doctor confirms that the forward play image still is the reverse play image; And according to displacement size calculating frame number side-play amount; Thereby calculate the present image frame number; Calculate the data address of present image according to every two field picture size, from the film memory block, read view data then and deliver to display screen and show.Under the single frames play mode; After if the doctor gives message of touch screen with direct or indirect mode; This message produces certain displacement but when not having this moment releasing action to produce, at this moment the images displayed frame number is relevant with current location, and along with the change of current location increases or reduce image frame number.If present speed gets into the movie pattern greater than presetting speed for the moment.Under the movie pattern, system confirms movie speed according to the threshold speed that presets speed two or three, can be with movie speed through the speed of presetting two or preset speed three and be divided into several speed thresholds, like high, medium and low three speed thresholds.The user can set up the number of the speed of presetting as required on their own.The actual film broadcasting speed is relevant with current doctor's speed of operation.When the doctor when needs suspend movie, can suspend movie through direct or indirect mode operating touch-screen, can continue movie from present frame when operating once more.
