Abstract

The present invention discloses improvements in the camera having an image memory for storing still image information, such that when a still image is displayed on a monitor, actuation of a camera release is ignored; when meaningless still images of the image memory are prevented from appearing on the monitor; and further good manageability of the camera is assured when writing and reading the image information in and from the image memory.

Claims

1. A camera comprising:

(a) image pick-up means for obtaining moving image data;

(b) first indicating means for manually indicating a still image capturing operation;

(c) first storage means for storing still image data captured from the moving image data;

(d) display means for displaying a moving image corresponding the moving image data before said first storage, means stores the still image data and for displaying a still image corresponding to the still image data stored in said first storage means after said first storage means stores the still image data;

(e) second indicating means for manually indicating a still image storing instruction; and

(f) second storage means for storing the still image data stored in said first storage means in response to the still image storing instruction,

wherein said first storage means stores the still image data in response to the still image capturing instruction if the still image capturing instruction is prior to the still image storing instruction, and

said first storage means stores the still image data in response to the still image storing instruction if the still image storing instruction is prior to the still image capturing instruction.

2. A camera according to claim 1, wherein said first indicating means includes a first manually operable key which is arranged on a body of the camera and said second indicating means includes a second manually operable key which is arranged on the body of the camera separately to the first manually operable key.

3. A camera according to claim 1, wherein said first storage means has smaller storage capacity than said second storage means.

4. A camera according to claim 3, further comprising means for inhibiting said first storage means from writing the moving image data in response to the still image capturing operation.

5. A camera comprising:

(a) image pick-up means for obtaining moving image data;

(b) first manually operable means;

(c) first storage means for storing still image data captured from the moving image data;

(d) display means for displaying a moving image corresponding the moving image data before the still image data is stored and said first storage means and for displaying a still image corresponding to the still image data stored in said first storage means after the still image data is stored in said first storage means;

(e) second manually operable means; and

(f) second storage means for storing the still image data stored in said first storage means in response to the operation of said second manually operable means,

wherein said first storage means stores the still image data in response to the operation of said first manually operable means if the operation of said first manually operable means is prior to the operation of said second manually operable means, and

said first storage means stores the still image data in response to the operation of said second manually operable means if the operation of said second manually operable means is prior to the operation of said first manually operable means.

6. A still image storing method, comprising steps of:

(a) inputting moving image data;

(b) displaying the moving image corresponding the moving image data;

(c) storing still image data captured from the moving image data into a first memory in response to a first manual operation if the first manual operation is prior to a second manual operation;

(d) storing still image data captured from the moving image data into the first memory in response to the second manual operation if the second manual operation is prior to the first manual operation;

(e) displaying a still image corresponding to the still image data stored in the first memory; and

(f) storing the still image data stored in the first memory into a second memory in response to a second manual operation while displaying the still image.

7. A method according to claim 6, wherein the first and second manual operations are executed by operating different keys.
