CONSTITUTION:An arithmetic means 201, a photometric circuit 205, a film feed detecting switch SW3 which is turned on and turned off plural times at every frame of film as the perforation of the film moves, and control means 207 which inputs the turning-on and turning-off signals of the switch SW3 and controls the arithmetic means 201 to execute calculation based on photometric information while film winding is performed are provided. Then an input port which is able to make switching between pull-up and pull-down is provided to the control means 207 and the turning-on and turning-off signals of the switch SW3 are inputted to the input port. While film winding is performed, the switch SW3 is controlled to pull down by means of the control means 207 and the output signal of the switch SW3 is maintained at a low level. Thus occurrence of electric noises is suppressed.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a camera control circuit, and more particularly to a camera control circuit equipped with anti-noise measures for photometric output in an autofocus camera.

[Conventional technology]

In general, errors in exposure calculation results in autofocus cameras can be caused by various factors.
Among these factors, it is thought that the influence of electrical noise accounts for most of them. Conventionally, various technical means have been used to eliminate the effects of electrical noise, and the costs involved are considerable. Two methods can be considered to reduce noise. One is to suppress noise by improving the noise generation source.
Another challenge is to improve the noise resistance of devices that are susceptible to noise. The only way to deal with the influence of noise that enters from the outside is to protect it on the device side, but there are several ways to protect against noise that occurs internally. For example, autofocus cameras are equipped with means for performing film advance detection. This is for automatically winding and rewinding the film of an automatic camera, and generally a switch means that is turned on and off by moving the perforations of the film is widely used. This switching means is often a so-called sprocket switch, which is turned on and off by rotation of a sprocket. Since the switch is turned on and off when the sprocket rotates regardless of whether the film is being wound up or rewound, it becomes a source of electrical noise during film winding. On the other hand, in an autofocus camera, photometry and exposure calculations for the next photograph are generally performed during film winding. If electrical noise from the noise source is added to the output signal of the photometric device, the result of this calculation may naturally have a large error, which may lead to a decrease in the reliability of the camera. Conventional cameras have had a problem in that noise from the switch affects the output signal of the photometric device, causing exposure errors. The sprocket switch is generally used for automatic control of initial loading and film rewinding, and the on/off signal of the switch is usually not used during film winding. Therefore, as a countermeasure against the noise from the sprocket switch, it is more economical to kill the output signal of the switch when it is not necessary for the function, rather than to improve the noise resistance of devices affected by the noise. In short, it's a good idea.

[Problem M that the invention attempts to solve]

The present invention has been made based on this viewpoint, and suppresses noise generation by reducing the output of the film feed detection switch to a low level during photometry and exposure calculations performed during film winding. The purpose is to provide a camera control circuit capable of controlling the output signal of the film feed detection switch so that the output signal of the film feed detection switch is pulled down when the switch is not needed, and pulled up when necessary. There is a particular thing.

[Means for solving the problem, and actions/effects] (Structure
In order to achieve the above object, the present invention was constructed as follows. That is, the control circuit of the camera of the present invention includes a calculation means for performing photometry and exposure calculations, a photometry circuit for inputting photometry information into the calculation means, and a photometry circuit that turns on and off multiple times per film frame by moving the perforations. and a control means to which an on/off signal of the switch is input and which controls the calculation means to perform calculations based on the photometric information during film winding. The control circuit for the camera is provided with an input port that can be switched between pull-up and pull-down, and an on/off signal for the film feed detection switch is input to the input port. The film feed detection switch is pull-down controlled by the control means. (Operation/Effect) According to the above configuration, since the film feed detection switch is pulled down during film winding, the output signal of the switch is held at a low level. Therefore, electrical noise is less likely to occur even if the switch is turned on or off as the film is wound up. In other words, the possibility that the photometry circuit signal (photometry information) will be affected by electrical noise from the switch is extremely low, and therefore the photometry performed during film winding is
The reliability of exposure calculation is high. In other words, it can be said that there is extremely little error between this calculation result and the measured exposure. On the other hand, outside of the film winding system, the film feed detection switch can be pulled up and the on/off output signal can also be held at a high level, so the above on/off output signal can be used for a given purpose. There is no equivalent problem in using the .
