下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
在本实施例中, 终端的图像显示方法, 应用于含有显示屏的终端中, 如 图 1所示, 该方法包括:
当检测到本终端被倒置后, 终端将本终端在被倒置前所显示的图像旋转 180度后输出显示。
在本发明的一实施例中, 将本终端在被倒置前所显示的图像旋转 180度 后输出显示可以釆用以下方式: 将本终端在被倒置前所显示的图像中各像素 点对应的坐标分别进行 180度旋转后输出显示。 具体的说, 即可以釆用更新 各像素点数据存放在緩存区域中的地址的方式实现图像旋转,具体方式如下: 首先获取图像每个点的像素值, 由于 180度旋转后图像大小不变, 只需 要逐点计算源图像中每个点旋转 180度后在新图像中对应点的坐标, 再将相 应像素值赋给它。 緩存区域大小等同于显示图像大小, 图像每个点对应于緩 存区域中的一个位置, 图像每个点的像素值存放于緩存区域对应的位置, 因 此, 180度旋转图像更新各点坐标即相应获得图像各像素值的存放地址; 下 面说明图像旋转坐标更新算法。 以图像中心像素点为原点坐标, 横向为 X轴, 纵向为 y轴, 图像每个点 各有一个 x、 y坐标值, 设某点坐标为 (xl、 yl), 与原点坐标距离为 r, 与 x 轴夹角为 a, 则 xl=r cos(a), yl=r sin(a); 旋转 180度后对应坐标为(x2、 y2 ) , 且 x2=r cos ( a+180 ) =r cos(a) cos(180) - r sin(a) sin(180)= -rcos(a)=— xl , y2=r sin ( a +180 ) =r sin(a)cos(180) + rcos(a)sin(180) = -rsin(a)= -yl
即坐标(x、 y )点旋转 180度后新坐标为 (-x、 -y ); 每一坐标对应一个 存放地址, 逐点计算源图像各点坐标旋转 180度后的新坐标, 将原坐标点像 素值赋给新坐标点即可完成输出图像 180度旋转显示效果。
在本发明的另一实施例中, 将本终端在被倒置前所显示的图像旋转 180 度后输出显示可以釆用以下方式: 利用显示装置的驱动集成电路 (IC , Integrated Circuit )所具备的扫描控制功能, 通过修改驱动 IC寄存器内容, 改变显示装置的扫描起始点和扫描方向, 实现所显示图像的 180度旋转。
通常, 驱动 IC的寄存器中保存有扫描方式控制字段、扫描起始点字段和 扫描方向字段。 扫描方式控制字段的值用于表示是沿垂直方向扫描还是沿水 平方向扫描; 扫描方向字段的值用于表示从左向右扫描还是从右向左扫描; 扫描起始点字段的值用于表示扫描起始点在显示屏上的位置。 在终端被正常 放置时, 扫描方向字段的值表示从左向右扫描, 扫描起始点字段的值表示显 示屏的左上角。 在检测到终端被倒置后, 可通过将扫描方向字段的值修改为 表示从右向左扫描、 将扫描起始点字段的值修改为显示屏的右下角的方式, 实现所显示图像的 180度旋转。
寄存器地址 R03h中保存有 AM、 I/DO, I/D1三个字段, 其中: AM字段 为扫描方式控制字段, I/D0和 I/D1分别为扫描起始点字段和扫描方向字段。 如图 2所示, 假设要在显示屏上显示一个字符 "F" , 设置 AM=0, I/D0=1 , I/D1=1 , 表示屏幕左上角为扫描起始点, 水平向右进行扫描, 右下角为扫描 终点; 当将 I/D0、 I/D1的值由 1更改为 0时, 则扫描起始点由左上角变为右 下角, 水平向左扫描, 左上角变为扫描终点, 则如图 3所示, 显示屏上会显 示一个倒置的 "F" 字符, 实现了 F画面的旋转 180度显示。
当上述终端为具有通话功能的设备时, 通常在显示屏的上侧会设置有第 一听筒, 在显示屏的下侧设置有第一麦克。 如图 4所示, 为保证终端被倒置 后仍可实现正常通话功能, 可在上述显示屏的上侧增设第二麦克, 在上述显 示屏的下侧增设第二听筒。 在终端处于正常使用方向时, 使第一听筒及第一 麦克处于工作状态, 使第二听筒及第二麦克处于非工作状态; 当检测到本终 端被倒置后, 该终端使第二听筒及第二麦克处于工作状态, 使第一听筒及第 一麦克处于非工作状态。
终端顶部和底部各设有一组功能相同的功能键, 每组功能键中包括若干 个功能对应的功能键(如图 5及图 6所示, 包括接听、 挂断、 菜单键等) 。 如果上述终端中还设置有触摸屏, 则也可将该两套功能相同的功能键以触摸 键的方式设在该触摸屏的顶端和底端。 这样, 即使终端旋转 180度后仍可方 便地进行相关操作。
此外, 在配置有触摸屏的情况下, 在该终端被倒置后, 当监测到有触摸 动作发生在该触摸屏上时, 将该触摸动作发生在该触摸屏上的位置的坐标旋 转 180度后, 根据旋转后的坐标执行相应的功能。
在本实施例中, 一种终端的图像显示系统, 含有显示屏, 还包括: 检测 装置和图像旋转装置, 其中:
所述检测装置设置成: 检测所述终端被放置的方向;
所述图像旋转装置设置成: 在所述检测装置检测到所述终端被倒置后, 将本终端在被倒置前所显示的图像旋转 180度后输出显示在所述显示屏上。
其中, 该显示屏可以但不限于为液晶显示器 (LCD , Liquid Crystal Display ) 、 有机电激光显示器 ( OLED, Organic Electroluminescence Display ) 等。
其中, 所述图像旋转装置设置成以如下方式将本终端在被倒置前所显示 的图像旋转 180度后输出显示在所述显示屏上: 将本终端在被倒置前所显示 的图像中各像素点对应的坐标分别进行 180度旋转后输出显示在所述显示屏 上。
