Abstract: A mobile terminal and a control method based on a user input for the same are provided. A text string contained in content may be erased according to the user input, and the erased text string is stored. When the user input is entered at the erasure region, a result of comparison between the stored text string and the user input is output. The control method includes detecting a first input, identifying color distribution of an input region corresponding to the first input, and erasing at least one object in the input region by applying the most commonly used color to the input region based on the identified color distribution.
Abstract translation: 提供了一种基于用户输入的移动终端和控制方法。 包含在内容中的文本字符串可以根据用户输入被擦除，并且被擦除的文本字符串被存储。 当在擦除区域输入用户输入时，输出存储的文本串和用户输入之间的比较结果。 控制方法包括检测第一输入，识别与第一输入对应的输入区域的颜色分布，以及基于所识别的颜色分布，将最常用的颜色应用于输入区域，来擦除输入区域中的至少一个对象。
