Abstract
The present invention relates to a digital camera with an adjusting device coupled with the lens and holes of the digital camera. The digital camera comprises a housing with a front opening installed at its front end for receiving incident light, a sensor installed at a rear end of the housing for recording the incident light, an iris strip moveably installed in the housing having a plurality of irises of different sizes for adjusting the amount of the incident light emitted to the sensor, a lens moveably installed in the housing for concentrating the incident light onto the sensor, and an adjusting device rotatably installed in the housing for adjusting positions of the lens and the iris strip. The adjusting device is rotated to move the lens to a plurality of lens positions to change the distance between the lens and the sensor. At each lens position, the adjusting device can also be rotated to move each of the irises on the iris strip to a position between the front opening of the housing and the sensor so as to adjust the amount of the incident light emitted to the sensor.
