Abstract

본 발명은 스틸카메라의 디스플레이장치에 관한 것으로, 촬영된 영상 정보의 일부를 확대하여 디스플레이할 수 있는 확대기능을 구비한 스틸카메라에 관한 것이다. 일반적으로 LCD로 촬영된 문자 또는 화상정보를 디스플레이할 때, 저장된 문자 또는 화상정보의 해상도에 비해 LCD의 해상도가 떨어지는 문제점이 있었다. 또한, LCD의 화면이 작기 때문에 촬영된 정보의 어느 한부분을 보고자할때, 불편함이 따랐다. 따라서, 본 발명은 사용자의 스위칭선택신호에 따라 일반모드와 확대모드를 선택하여 디스플레이모드를 변경할 수 있고, VRAM에 저장된 화상정보의 독출시간을 늦춰 VRAM에 저장된 화상의 일부를 확대하여 디스플레이할 수 있고, 확대모드에서는 사용자가 세로위치 및 가로위치를 임의로 입력하여 확대화상의 위치를 이동함으로써, 원하는 부분의 확대정보를 얻을 수 있는 잇점을 제공한다.The present invention relates to a display device of a still camera, and relates to a still camera having an enlargement function capable of enlarging and displaying a part of photographed image information. In general, when displaying the character or image information photographed by the LCD, there is a problem that the resolution of the LCD is lower than the resolution of the stored character or image information. In addition, since the LCD screen is small, it was inconvenient to see any part of the recorded information. Therefore, the present invention can change the display mode by selecting the normal mode and the magnification mode according to the user's switching selection signal, and can enlarge and display a part of the image stored in the VRAM by delaying the reading time of the image information stored in the VRAM. In the magnification mode, the user arbitrarily inputs the vertical position and the horizontal position to move the position of the magnified image, thereby providing an advantage of obtaining magnification information of a desired portion.

Claims

A display device of a still camera, comprising: a memory storing an image signal; First clock dividing means for dividing a horizontal clock for reading an image signal stored in the memory to variably adjust an output speed of a read clock signal; Second clock dividing means for dividing a vertical clock for reading pixels constituting one line of the image signal stored in the memory to variably adjust an output speed of the read clock signal; And a display unit configured to display a video signal stored in the memory according to a read clock signal variably applied from the first clock divider and the second clock divider.

The still camera having an enlargement function of claim 1, wherein the memory comprises an image storage unit for storing a video signal and a SAM port for temporarily storing a line of image information read from the image storage unit.

2. The apparatus of claim 1, wherein the first clock divider comprises: a horizontal address value counter for receiving a horizontal synchronization signal (HSYNC) and a vertical synchronization signal (VSYNC) and counting the horizontal synchronization signal using the vertical synchronization signal as a reset signal; A first switching unit for outputting a user vertical position selection value applied from the outside to the adder according to a user mode selection signal; An adder configured to add a horizontal address value input from the horizontal address value counter and a vertical position selection value applied from the first switching unit to generate a clock to find a vertical position start point of an image signal stored in the memory; A first clock divider which transfers the clock of the vertical position starting point applied from the adder as it is; A second clock divider for dividing a clock for a vertical position starting point from the adder by a predetermined size to adjust a horizontal address value read clock at a predetermined speed to a predetermined speed and output the same to the memory; And a second switching unit configured to variably select the first and second dividers according to a user mode selection signal.

3. The apparatus of claim 1 or 2, wherein the second clock divider comprises: a clock generator for generating a clock for reading a pixel value of a line of image information stored in the SAM PORT; A third divider which transfers the clock applied from the clock generator as it is; A fourth divider for dividing a clock applied from the clock generator to a predetermined size to adjust an output speed of a vertical address value read clock; And a third switching unit configured to variably select the third and fourth dividers according to a user mode selection signal applied from the outside.

The still camera having an enlargement function of claim 1, wherein the memory receives a user horizontal position value from an external device and adjusts an output position of a pixel stored in a SAM port of the memory.
