Description

Digital camera with memo function and save method

The present invention relates to a digital camera having a memo function and a method of storing the same. More specifically, a product performance of a digital camera is displayed by synthesizing and displaying a message or memo desired by a user using an electronic pen and a sensor plate. The present invention relates to a digital camera having a memo function for improving the method and a storage method thereof.

In general, a digital camera converts an image incident through a lens into an electrical signal using a photoelectric conversion element such as a charge coupled device (CCD), and stores the result in a memory device such as a semiconductor memory device or a magnetic tape. Video input and storage device.

Types include a digital still camera (DSC), which captures images intermittently and stores them in a semiconductor memory device, and a digital video camera, which records images continuously and stores them on a storage medium such as magnetic tape. DVC).

And all these digital cameras can be connected to the computer device to send and receive data.

That is, by storing the image data photographed with the digital camera in the storage device of the computer device separately, it is possible to improve the image storage capacity, and to control the operation state of the digital camera using the computer device.

These digital cameras have recently expanded and expanded the use of home computer devices to view and edit images taken by themselves through computer display devices using computer devices to create multimedia homepages or presentation materials or to output edited images such as printers. It can be output to a device or can be stored in a hard disk drive or a compact disk.

For example, you can make a homepage using images taken with a digital camera by connecting to the Internet, create a variety of reports by inserting photographed images, and create an electronic album with commemorative photos such as graduation and marriage. It can be made or stored in a recording medium such as a diskette.

Such digital cameras typically provide VGA (640 x 480) or higher resolution and have a large memory to record and record a large number of subjects.

First, the electronic pen is recorded on the sensor plate of the DSC or the DVC (S51). When the user writes a desired message or image on the sensor plate, the sensor plate recognizes the position and direction information, and when the message or image is transmitted to the data converter, the sensor plate is converted into data by the data converter (S52).

In this case, the user may adjust the black, white, and color levels according to the size of the data. That is, the user may select a desired type of color using the color selection key (S53).

After the selection of the contents, the size and the color of the memo to be recorded is completed, the user is temporarily stored in the DRAM for memo using the storage input key S54 (S55).

The recording information temporarily stored in the DRAM for memo is directly synthesized with the image information stored in the image DRAN4, and the synthesized information is finally stored in the flash memory card of the DSC or the main DRAM of the DVC (S57).

The control of all systems in the above process is carried out by a soft program of the main controller, and the method of storing the memo contents or messages recorded by the electronic pen in the digital camera is the same for both DSC and DVC.

In addition, when inputting a message or memo that an external user wants to combine with image information, input is made through a separate sensor plate instead of directly through a display device such as an LCD to prevent damage that may occur to the display device such as an LCD. It will have more effect to reduce.
