Canon’s new “Imagine Device” patent from the Japan Patent Office, demonstrates a method to cool the media cards in the Cinema EOS models. Check out the application’s highlights below.
Canon’s patent: Heat dissipation of the media cards
Canon has published a new patent application titled Imagine Device” from the Japan Patent Office (not yet published in the U.S.) which demonstrates a method to cool the media cards in the Cinema EOPS lineup. Although the application does not refer to the Cinema EOS models specifically, we can assume that this apparatus will be implemented in the Cinema EOS since the application defines that this solution is being designed to mitigate the heated media card derived from shooting RAW at high-resolution and FPS. Anybody who shoots 4K RAW files and beyond, knows that the media card can be extremely hot. Hence, it’s not just cooling the sensor or the camera body in general, but those media cards need to be addressed as well.
Preserving compactness
The application suggests a method and apparatus that will preserve the compact form factor of the Cinema camera, and prevent another cooling system from making the camera larger. As stated in the application (Google translated from Japanese): “Other patents do not take into consideration the cooling of the recording medium. If a new structure for cooling the recording medium were added, the device would become larger. With the increase in writing bit rate due to future improvements in image quality, it is predicted that the amount of heat generated by the recording medium will further increase, so it will be necessary to efficiently cool the recording medium. An object of the present invention is to efficiently cool the recording medium while suppressing the device from becoming larger. In order to achieve the above object, the imaging device of the present invention is characterized by having a gripping part that is arranged on the imaging device body and is gripped during use, a control board that is provided on the imaging device body and is approximately perpendicular to the optical axis direction, a storage part that is mounted on the control board at a position that does not overlap with the gripping part when viewed from the optical axis direction and is capable of storing a recording medium, and a heat dissipation duct that is arranged at a position that does not overlap with the gripping part when viewed from the optical axis direction and is thermally connected to the storage part. According to the present invention, it is possible to efficiently cool the recording medium while suppressing the device from becoming larger”.
Summary of Invention
It seems that this patent application is important and essential since media cards in cinema cameras become extra hot, and that can cause for damaging the cards. Cooling those cards can mitigate malfunctions, delay EOL, and elevate efficiency. Hence, cinema camera will have two cooling systems: One for the sensor, and another for the media.
