Abstract

PURPOSE:To obtain a digital still picture of high image quality together with moving pictures by adding a digital still picture recorder to a camcorder. CONSTITUTION:A still picture signal is taken out of an image pickup element 102 of the camcorder 101 and is supplied to a conversion section 104 which converts the signal to a digital signal. This signal is thereafter subjected to image processing, such as image compression and error correction and is digitally stored in an external memory device 10, by which the still picture is preserved. The image signal is read out of the external memory device 10 at the time of reading out the digital still picture. This signal is converted to an analog signal in the conversion section 104 and thereafter, the still picture is displayed on CRT 107. The digital still picture having the good image quality is obtd. in this way.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a camera-integrated VTR device, and particularly to a VTR device.
The present invention relates to a camera-integrated VTR device that has a high-quality digital still image recording function added to the above functions.

[Prior Art] Generally, when viewing a still image on a VTR device, the tape is stopped and the still image at that tape position is viewed.

At this time, when the head is scanned, the head may deviate from the recording track, causing the H alignment to shift, or the S/N ratio of the reproduced signal may deteriorate, resulting in noise bands and deteriorating the still image. In order to prevent this, a part of the reproduced video image is A/D converted and stored on RAM, and the signal read from RAM is converted to D.
/A conversion is performed to obtain a still image.

[Problems to be Solved by the Invention] However, since these signals are recorded on tape, deterioration in the S/N ratio is unavoidable.

The camera-integrated VTR device of the present invention has been developed in view of these problems, and its purpose is to add a digital still image recording device to the conventional camera-integrated VTR device to record high-quality images as well as moving images. An object of the present invention is to provide a camera-integrated VTR device capable of obtaining high-quality digital still images.

[Means for Solving the Problems] In order to solve the above problems, the camera-integrated V of the present invention
The TR device is a camera-integrated VT having an image sensor and a storage means for storing moving images extracted from the image sensor.
In the R device, an external storage means is provided outside the camera-integrated VTR device in order to extract still images from the image sensor and store and reproduce them separately from the moving images.

[Function] In the present invention, the conventional camera-integrated VTR device is
An external storage device such as a C card memory is connected using a connection terminal, and a function for recording digital still images on the external storage device is added to the moving image recording function of a VTR. In other words, a camera-integrated VTR device is equipped with an A/D conversion function, an image processing function, a D/A conversion function, and an external storage device control function, and inputs and outputs high-quality digital images to the external storage device via an external connection terminal. It is something to do.
