具体实施方式 Detailed ways

本发明采用的将手机电3见播放画面进行局部放大观看的方法可以应用在显示屏具有触摸功能的移动终端上,也可以应用在显示屏不具有触摸功能的移动终端上,用户可以随意选择需要局部》文大的显示区域,也可以随意诏二置放大后的显示区域大小。 The present invention is employed will see the mobile phone 3 displays a screen electrically method can be applied to a partially enlarged view of a display screen on a mobile terminal having a touch function may be applied on a display screen does not have a touch function of the mobile terminal, the user can freely select local "large text display area may be arbitrarily large size of the display area Chao after two placement. 以显示屏具有触摸功能的移动终端为例,下面对本发明的具体实施例进行描述。 In the mobile terminal having a touch screen function, for example, the following specific embodiments of the present invention will be described.

如图1所示,为本发明实施例使用移动终端在收看手机电视的时候对播放画面进行局部放大观看的流程图,所述移动终端以具有触摸功能的移动终端为例,但本发明不局限于具有触摸功能的移动终端上为例,其具体步骤如下: 1, the mobile terminal of the present embodiment uses a partial enlarged view of the flowchart in watching mobile TV picture playback time of the invention, the mobile terminal having a touch function of the mobile terminal as an example, but the present invention is not limited Example on the mobile terminal having a touch function, the specific steps are as follows:

步骤101:先在具有手机电视功能的移动终端中设置放大后显示区域的位置A和尺寸大小B51^,位置A可以按照左上、中上、右上、居中、左下、 中下、右下等方位进行设置,也可以按照具体的坐标进行设置,尺寸大小B*C可以按照用户的需求进行设置,但是要求尺寸框的长度B和宽度C不能大于LCD显示屏中手机电视显示区域的长度L和宽度W;虽然本实施例是预先设置放大后显示区域的位置和大小,但在其他实施 Step 101: A first set display position and size of area B51 ^ amplified in a mobile terminal having a TV phone function, can follow the position A on the top left, middle, right, center, left lower, lower, lower right orientation, etc. setting, can also be provided according to specific coordinates, size B * C can be set according to the user's needs, but the size of the required frame length B and C is not greater than the width of the LCD display of the mobile television display region length L and width W ; Although the embodiment of the present embodiment is set in advance enlarged display position and size of the area, but in other embodiments

例中,也可以不进行预先设置。 Embodiment, may not be set in advance. 例如在步骤104中,在选取了要放大的显示区域后,可以再选取放大后的显示区域,或者输入l个访文大比例,以选取或默认的要放大的显示区域的一个端点或中心点为基点得到放大后的显示区域。 A terminal or a central point, for example, in step 104, when selected for enlarged display region, can then select the display area of ​​the enlarged, or the input l-th access text large proportion, to select or default to the enlarged display area is bp amplified region to obtain the display.

步骤102:移动终端开启电视播放功能,用户选择某个频道进行播放, 然后将接收到的对应频道的电视信号解码后发送给的第一緩冲区M; Step 102: The mobile terminal displays the TV function is turned on, the user selects a channel for playback, then sent to the M first buffer and decodes the received television signal to a corresponding channel;

步骤103:从緩沖区M中将接收到的保留了最大分辨率S*T的原始视频帧数据按照显示屏中手机电视显示区域分辨率大小L*W进行插值或缩小处理后放入緩冲区N中,然后从緩冲区N中读取数据在显示屏上进行显示; Step 103: receive it from the buffer to retain the original M to the maximum resolution of the video frame data S * T according to the display resolution size of the display area mobile TV L * W or reduced interpolating process into the buffer in N, N then reads data from the buffer is performed on a display screen;

步骤104:用户开启放大显示功能,在显示屏的电视播放区域内选取需要放大的显示区域的两个对角位置的点,移动终端获取到该区域两个对角的位置坐标(Xl, Y1)和(X2, Y2); Step 104: the user turns on an enlarged display, enlarged display needs to select two points on the region of the angular position of the television in the area of ​​the display, the mobile terminal obtains the position coordinates of the region of two corners (Xl, Y1) and (X2, Y2);

点,还可以是用触摸笔在触摸屏上划出一个包含显示区域的闭合图形,由移动终端进行校正处理为一矩形区域;也可以是选取显示区域的三个或更多的端点位置,移动终端将主些端点所包含的区域作为显示区域放大;也可以是移动终端提供一个动态显示的初始矩形框(或其他形状的框),用户可以用手或笔选中该初始矩形框上或附近的某个用于定位的点后拖动到想要的位置,然后选中该矩形框上或附近的某个用于缩放的点并拖动完成显示区域大小的设定。 Point, may also be touch pen on the touch screen to draw a closed figure comprising the display area, the correction processing performed by the mobile terminal is a rectangular region; selected display area may be three or more end positions, the mobile terminal the main area of ​​these endpoints included as a display area enlargement; may be a mobile terminal provides a dynamic display of the initial rectangle (or other shape of the block), the user can select a pen or by hand on or near the initial rectangular frame after locating a point for the drag to the desired location, and then select or for scaling a point in the vicinity of the display area and drag to complete the setting of the size of the rectangular frame. 这里可以使用的方式非常之多,不再一一枚举。 Here are ways to use very much, not going to enumerate.

步骤105:将两个对角位置的坐标信息与用户设置的放大后显示区域的尺寸大小B^进行比较,如果以两个对角位置确定的矩形区域的尺寸大于B*C,执行步骤106,否则执行步骤107; Show enlarged two coordinate information of the user and disposed on the angular position of the region B ^ comparing size, if the size of two diagonal positions of the rectangular determination region is greater than B * C, step 106: Step 105 otherwise, executing step 107;

步骤106:弹出信息"选取区域大于设置区域",提示用户进行重新选择或设置,然后执行步骤104; Step 106: pop-up message "setting area larger than the selection area", prompting the user to re-select or set, then step 104 is executed;

步骤107:从緩冲区M中保留原始最大分辨率的视频数据帧中读取用户所选择区域的部分视频数据,视频数据读取是从两个对角位置坐标(Xl, Yl)和(X2, Y2)选择完毕时刻的那一帧画面的数据帧开始,此用户选择区域在从緩冲区M中分辨率为S*T的原始视频数据帧的具体位置为以(X1', Yl')和(X2', Y2')为对角线的矩形区域,其中Xl'= X1*S/L, Yl'= Y1*T/W, X2'= X2*S/L, Y2'=Y2*T/W; Step 107: Reserved maximum resolution of the original video data from the buffer frame M to read the user data portion of the selected video area, the video data read from two diagonal position coordinates (Xl, Yl) and (X2 , Y2) After selecting a data frame picture that time frame starts, the user selects a particular location area in the original video frame buffer from M S * T is the intermediate resolution data is at (X1 ', Yl') and (X2 ', Y2') of the diagonal of a rectangular area, wherein Xl '= X1 * S / L, Yl' = Y1 * T / W, X2 '= X2 * S / L, Y2' = Y2 * T / W;

步骤108:将读取的以(Xl', Y1')和(X2', Y2')为对角线的矩形区域的视频数据按照用户设置的放大后显示区域的大小B*C相应进行插值或缩小处理,再与緩存N中已经按照显示屏的分辨率大小1^W进行插值或缩小处理后的视频数据重组,将位置A处尺寸大小为B*C的矩形范围内的原视频数据覆盖。 Step 108: In the read (Xl ', Y1') and (X2 ', Y2') the video data corresponding to the diagonal of the rectangular area in accordance with the interpolated display region B * C size set by the user to enlarge or reduction processing, and then the original video data has been performed within the coverage of the rectangular range B * C interpolation or reduce the video data after the recombinant process, the size of the position a cache size N in accordance with the display resolution of 1 ^ W.

其中,局部放大时保持局部视频的长宽比,局部视频保持长宽比例放大后的尺寸为B'W,满足如下条件:B^B且C、C或者OC且B'《B,最后从緩沖区N中读取数据进行显示,这样的处理流程相对于直接从緩存N中将用户所选区域的部分视频数据进行插值处理后再覆盖放大后显示区域的原视频数据的方法可以最大限度的减少在放大过程中造成的图像失真,保持放大部分图像的最高清晰度。 Wherein the holding enlarged partial video aspect ratio, maintaining the dimensions of the partial video enlarged aspect ratio B'W, satisfy the condition: B ^ B and C, C or OC and B ' "B, and finally from the buffer N read data area for display, the original method of video data can minimize the area of ​​such a display after processing flow with respect to cover amplification directly from the interpolation processing section N in the buffer for video data after the user selected area cause image distortions in the amplification process, to maintain the highest resolution of enlarged image portion.
