Abstract

A conventional image recording apparatus like a video camera recorder may often bring about coding noises if an image to be inputted or a target object reaches a certain degree of complexity. The remaining time when data is to be recorded on a recording medium may be so varied according to the magnitude of the coding rate that the time cannot be easily grasped. To overcome these problems, the present image recording apparatus is arranged to vary the display based on the coding rate according to the magnitude of the coding rate so that the user can grasp how much the coding noises appear with sense. Further, by displaying the remaining volume and the coding rate of the recording medium associated therewith, the decreasing pace of the remaining time may be notified to the user.

Claims

means for coding an video signal;

means for recording coding information obtained from said coding means on a recording medium;

means for displaying a magnitude of a coding rate of said coding means; and

said means for displaying a coding rate varying the form of the display according to the magnitude of said coding rate.

2. An image recording apparatus as claimed in claim 1, wherein the coding rate of said coding means is compared with a predetermined value and the display form of said coding rate displaying means is changed on the compared result.

3. An image recording apparatus as claimed in claim 1, wherein said means for displaying a coding rate varies a display color according to the magnitude of said coding rate.

4. An image recording apparatus as claimed in claim 1, wherein the value of coding rate of said means for displaying a coding rate varies according to the magnitude of the coding rate of said coding means.

5. An image recording apparatus as claimed in claim 1, further comprising:

means for displaying a remaining time when data is to be recorded on said recording medium; and

wherein said means for displaying a remaining time serves to vary the display form according to the magnitude of said coding rate.

6. An image recording apparatus as claimed in claim 5, wherein said coding rate value of said coding means is compared with a predetermined value and said means for displaying a remaining time serves to vary the display form based on said compared result.

7. An image recording apparatus as claimed in claim 5, wherein said means for displaying a remaining time serves to vary the display color for indicating the remaining time.

8. An image recording apparatus as claimed in claim 5, wherein said means for displaying a remaining time serves to vary the display size based on the quantity of the coding information to be recorded on said recording medium.

9. An image recording apparatus as claimed in claim 5, wherein means for displaying a remaining time serves to change the display color according to the magnitude of said coding rate.

10. An image recording apparatus as claimed in claim 5 or 6, wherein said means for displaying a remaining time serves to change the display size according to the magnitude of said coding rate.

11. An image recording apparatus as claimed in claim 5, wherein said means for displaying a remaining time serves to change the flashing times of the display per unit time according to the magnitude of said coding rate.

12. An image recording apparatus as claimed in claim 1, further comprising:

a camera optical system;

means for processing a signal sent from said camera optical system;

finder means for viewing a target object; and

a power supply circuit.

14. An image recording apparatus as claimed in claim 13, wherein said means for compressing and coding a video signal serves to increase a display value for the coding rate if the coding rate is made greater according to the complexity of an image or decrease a display value for the coding rate if the coding rate is made smaller according to the simplicity of an image.
