Operation is secured. FIG. 4 shows an example of the above-described adjustment system. In this example, a probe connection portion 3 that can be covered with a decorative cover 2 is arranged on the front surface of the camera 1. A needle hole 4 having an adjustment contact provided therein is formed in the probe connection portion 3, and a plurality of contact needles 7 are provided in a probe 6 on one adjuster 5 side. Accordingly, if the contact needle 7 of the probe 6 is inserted into the needle hole 4 and connected to the adjustment contact, a signal can be transmitted between the adjuster 5 and the MPU or the like inside the camera.
In addition, for example, in the case of performing adjustment relating to exposure, an exposure amount detection unit (not shown) is arranged in the aperture unit of the camera 1 to detect the actual exposure amount.

[0003] According to this, from the adjusting device 5 to the camera 1
The camera 1 performs a predetermined photographing operation in response to the operation signal. At this time, it is determined whether or not the photographing operation is a normal operation based on a predetermined criterion. For example, regarding the exposure, an actual exposure amount is detected by an exposure amount detection unit, and a determination based on the detected value is performed. . If the difference is different from the reference value, the difference from the reference value is calculated by the adjuster 5 as a correction value, and the correction value is written into a memory such as a ROM in the camera 1. The shooting operation is adjusted for each camera.
