Abstract

PURPOSE:To discriminate whether picture information is an original version, or a copy version or a revised version in the case of reproduction of a picture recording medium by recording identification information representing which of the original version, the copy version and the revised version generating information corresponds to the picture recording medium together with the picture information. CONSTITUTION:An additional information generating section 108 generates reproduction processing information required for picture reproduction processing, that is, additional information including a compression system of the picture information, a data arrangement (RGB system or YC system), information such as screen size, and identification information whether a picture recorded on a memory card 12 is an original version, or a copy version or a revised version. When an object field is picked up by an image pickup device 102 through an image pickup lens 100, a picture processing section 106 applies color signal processing and compression coding processing to the picture and converts the picture into picture information with a prescribed format and receives the additional information from the additional information generating section 108 and stores the additional information(AI) and the picture information(PI) onto the memory card 12 in the unit of picture.

The imaging device 102 advantageously uses a solid-state imaging device such as a CCD, which photographs a field with the imaging lens 100 and generates a color image signal representing the field, for example (
This is an imaging device that outputs color component signals of R), green (G), and blue (B). This color component signal is output in a rask scanning format similar to a TV signal. Other functional units necessary for photographing, such as an exposure mechanism and a focusing mechanism, are not directly related to the understanding of the present invention, and therefore their explanation will be omitted. The memory card 12 is
A semiconductor memory device, for example a RAM, is an image recording medium carried on a card-like base and is advantageously removably mounted on the device.

The output end of the imaging device 12 is connected to an A/D converter 104, and the A/D converter 104 is a signal conversion circuit that converts an input analog image signal into corresponding digital data and outputs it. This digital data is quantized into, for example, 8 bits for each of the color component signals RGB. This digital data is input to the image processing section 106.

The image processing unit 106 includes a signal processing circuit that converts the digital data (color signal component data) into a luminance signal and a two-phase color difference signal, and a compression encoder that compresses and encodes the image information output from this signal processing circuit. It is composed of circuits, etc.

The additional information generation unit +08 generates reproduction processing information necessary for image reproduction processing, that is, image information compression method, data array fR.
(GB system or YC system), screen dimensions, and additional information including identification information indicating whether the image recorded on the memory card I2 is an original version, a copy version, or a modified version.

In the above configuration, when a field is imaged by the imaging device 102 through the photographic lens 100, the image signal is converted into digital data by the A/D converter 104. This digital data is input to the image processing unit 106. The image processing unit 106 performs color signal processing and compression encoding processing on this digital data to convert it into image information in a predetermined format, and also converts it into additional information. Upon receiving the additional information from the generation unit 108, the additional information (A
I) is stored for each screen. Figure 2 shows the memory card 12
This shows a state in which image data (PI) and additional information (AI) are stored.

In the same figure, a memory area 30 is provided on the memory map of the memory card 12 in which data is stored in screen units. ) is stored.

Next, the configuration of another embodiment of the still image recording apparatus according to the present invention is shown in FIG. This embodiment differs in configuration from the embodiment shown in FIG.

The additional information reproducing unit 40 reads and reproduces additional information (AI) recorded on the memory card 12 together with image information (PI) on a screen-by-screen basis as shown in FIG. Reproduction processing information (data such as compression method, data arrangement, screen size, etc.) necessary for image reproduction processing is sent to the image processing unit 400, and whether the image information recorded on the memory card is an original version, a copy version, or a modified version. Identification information indicating the identity is output to the control unit 408.

The control unit 410 determines whether the still image displayed on the monitor television 406 is an original version, a copy version, or a modified version,
A control signal for displaying the determination result on monitor television 404 is output.

In the above configuration, the image information (PI) read from the memory card 12 is supplied to the image reproduction processing section 400, and the additional information (AI) is supplied to the additional information reproduction section 408.

The additional information reproducing unit 408 reproduces additional information (AI),
Among the reproduced additional information, reproduction processing information necessary for image reproduction processing is sent to the image processing section 400, and identification information is sent to the control section 4.

The image reproduction processing section 400 expands/decodes the image information read from the memory card 12 based on the reproduction processing information given by the additional information reproduction section 406, and decodes the image information read from the memory card 12.
Output to 02. The analog signal converted by the D/A converter 402 is converted into an R, G, B signal or a television signal such as NTSC by a signal processing circuit 404, and outputted to a monitor television 406 for image display.

On the other hand, the control unit 410 determines whether the still image displayed on the monitor television 406 is an original version, a copy version, or a modified version based on the identification information provided by the additional information reproduction unit 408, and displays the determination result. Control signal monitor TV 40
Output to 6. As a result, the still image and information indicating whether the image is an original, a copy, or a modified version are displayed on the screen of the monitor television 406.

As explained above, in the present invention, in a still image recording device that records image information on an image recording medium screen by screen, it is possible to determine whether the image information is an original, a copy, or a modified version along with one image information. Since the configuration is configured to record identification information indicating the image recording medium on the image recording medium, when the image information read from the image recording medium is reproduced, it is possible to determine whether the image information is an original, a copy, or
It is possible to determine which version is the corrected version. If the system is configured so that the additional information cannot be changed by the operator, an image in which the additional information indicates the original can be used as a valid photographic evidence.
