Problems solved by technology

[0011] However, since the controller 30 adjusts the number of motion picture frames by skipping every other vertical sync signal, a large load is applied
Issues that cause a large number of resized frames to be reproduced in Motion Picture and the displayed Motion Picture screen to be separated or distorted

Abstract

A wireless terminal includes a camera for shooting an image when the wireless terminal is set to a camera mode, and outputting the shot image data in units of a frame. An image processor outputs video frames from the camera in a predetermined number per unit time, and generates and outputs a synchronization signal for the output video frames. A pulse generator generates a predetermined converted pulse to scale down a frame frequency of a vertical synchronization signal of the synchronization signal at a predetermined ratio. A converter generates and outputs a converted vertical synchronization signal where the frame frequency of the vertical synchronization signal is converted at a predetermined ratio. A controller adjusts the number of video frames input from the image processor in a predetermined number per unit time, and controls the adjusted frames to be displayed on a display unit.

Description

technical field [0001] The present invention relates to a wireless terminal. More particularly, the present invention relates to a wireless terminal for reducing distortion of a moving picture screen displayed on a display unit of the wireless terminal. Background technique [0002] Recently, wireless terminals have been provided with cameras, and have allowed display of image signals input from the cameras. Thus, a wireless terminal having a camera can capture an image to display a moving picture or a still picture based on frame processing, and transmit the captured image. [0003] figure 1 is a block diagram showing a conventional wireless terminal. [0004] The wireless terminal shown includes: a camera 10 , an image processor 20 , a controller 30 and a display unit 40 . [0005] The camera 10 captures an image, and outputs image signal data of the captured image to the image processor 20 frame by frame. [0006] The image processor 20 proces...
