Summary: | PURPOSE:To provide a camera automatically having the filter function without using a filter by automatically emitting the correction light in the color corresponding the color tone of the external light inside of a camera box, and irradiating a film with the external light and the correction light simultaneously, and sensitizing it. CONSTITUTION:A camera with a built-in filter function automatically computes the color of the correction light for correcting the color tone of a light source 2, which is arranged inside of a camera and which consists of a light emitting material for emitting the light in the appropriate color, and the external light 6 to a desired color tone. A control system 8 for controlling the light emitting material so that the light source 2 emits the correction light in a desired color tone and an optical system for making the correction light emitted from the light source 2 and the external light 6 work on the sensitive surface of a film 3 evenly are provided. This light source 2 consists of plural light emitting material arranged on the circumference for surrounding the external light 6, and each light emitting material is operated for light emission/quenching by turning on/off the voltage to be applied. |
