Volume control linked with zoom control
First Claim
Patent Images
1. A camera comprising:
- a record button;
a lens;
an image sensor for receiving images viewed by the lens;
a speaker;
an audio amplifier; and
processing circuitry that comprises a control algorithm that implements an automated zoom control function that automatically records images having different zoom levels while depressing the record button, and which, upon playback, adjusts the gain of the audio amplifier to adjust the sound output volume in an amount related to the zoom level recorded by the zoom control function.

Abstract
Digital cameras and methods wherein volume control is linked with zoom control. The present invention captures audio along with recorded images at different zoom settings, and upon playback adjusts the sound output volume (audio apparatus gain) based upon the zoom control setting.

6. A camera comprising:
-
a record button;
a lens;
a mechanical zoom control that moves certain optical elements of the lens to different physical positions;
an image sensor for receiving images viewed by the lens;
a speaker;
an audio amplifier; and
processing circuitry that comprises a control algorithm that implements an automated zoom control function that zooms the lens while recording images and simultaneously adjusts the gain of the audio amplifier as a function of zoom position, and which, upon playback, adjusts the gain of the audio amplifier to adjust the sound output volume in an amount related to the zoom level recorded by the zoom control function. - View Dependent Claims (7, 8, 9)
