Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of the first embodiment, in which light from a subject passes through an optical system 1 and C
The image is made incident on the solid-state image sensor 2 such as a CD. The solid-state image sensor 2 converts the formed image into an electric signal (image signal),
This is supplied to the A / D converter 3. The A / D converter 3 is
Convert the supplied analog signal to a digital signal sequentially,
Stored in the memory 4. Since the solid-state image sensor 2 outputs the image data for each screen, the memory 4 stores the image data for one screen. A photographing mode changeover switch is connected to the control unit 5, and the photographing mode changeover switch is used to switch between the normal photographing mode and the image processing mode.

A signal from the release is supplied to the control unit 5, and the image data stored in the memory 4 when the depression of the release is detected is composed of an IC card or the like. It is controlled so as to be supplied to the external storage unit 6. Therefore, the image at the time when the release is pressed can be recorded in the external storage unit 6.

The flow of processing in the present invention is shown in the flowchart of FIG.

Image data is input (step S1)
Then, the control unit 5 determines the shooting mode (S
2). In the normal shooting mode, the image data stored in the memory 4 when the release button is detected is directly sent to the external storage unit 6 without any processing and stored in the storage medium (S7).

On the other hand, in the image processing mode, in addition to the image data stored in the memory when the release press is detected, a menu indicating the processing item and a cursor for selecting the processing item are displayed on the image display unit 7. Display on (S
3). A display example at this time is shown in FIG.

A processing item selection means is connected to the control section 5, and the processing item selection means moves the cursor in the image display section 7 to select a menu and its processing item to determine a processing method (S4). ). The processing here is, for example, binarization processing, enlargement / reduction, color conversion, or the like.

When a processing item is selected, the image processing unit 8 performs image processing on the image data stored in the memory 4 based on the selected processing item (S5) and sends the processing result to the image display unit 7. Display is performed (S6).

In the image processing mode, selection of a processing item (S
4), the image processing (S5) and the display of the processing result (S6) are repeated, and the processing is terminated when the desired image is obtained, and the image data stored in the memory 4 and the processing applied to the image data. The processing information indicating the content is recorded in the external storage unit 6 including an IC card or the like (S7).

FIG. 4 is a block diagram showing the overall construction of the second embodiment of the present invention, in which the same components as those in FIG. 1 are designated by the same reference numerals.
