Abstract

A camera captures an object'"'"'s image and generates image data. An image processor processes the image data generated by the camera on the basis of a predetermined display standard. A user data generator generates user data according to a display mode. A display unit displays the image data on a first display area and displays the user data on a second display area. A controller controls transmission paths such that the image data from the image processor is transmitted to the first display area of the display unit in a first display time for a frame, and the user data is transmitted to the second display area in a second display time, at each frame when an operating mode is an image capture mode.

a display unit for displaying the image data on a first display area and displaying the user data on a second display area; and

a controller for cutting off a path of the image data by controlling the display data processor in a still-picture capture mode, compressing the image data displayed on the first display area by driving the image codec, and storing the compressed image data as a still picture in a memory.

10. The device as set forth in claim 9, wherein the controller controls transmission paths such that the image data from the image processor is transmitted to the first display area of the display unit in a first display time, and the user data is transmitted to the second display area of the display unit in a second display time, at each frame when an operating mode is an image capture mode.

11. The device as set forth in claim 10, wherein the first display time is a period of time between a time point of generating a first horizontal synchronous signal when valid frame data begins to be transmitted and a time point of generating a vertical synchronous signal, and
