A new Canon patent application for RF mount lenses with "Defocus Smoothing" (DS) optical technology.…
Here is a new Canon patent application, about cooling and image stabilisation in a Cinema EOS camera body.
Canon patent application 2023163923 (Japan, published 11/10/2023) discusses methods and technology for a cooling structure and an image stabilisation system for what appears to be a Cinema EOS camera body.
From the patent literature:
- An object of the present invention is to provide an imaging device that is miniaturized, can arrange a portion that can provide an image stabilization function for an imaging section, and can rapidly cool an imaging element.
- BACKGROUND ART
In recent years, imaging devices have been achieving higher image quality such as higher resolution and higher frame rate of recorded images. In such imaging devices, the signal processing load and power consumption during image recording tend to increase, and as a result, electronic components such as the imaging section and the data recording section generate significant heat. Since the performance of electronic components within an imaging device may deteriorate at high temperatures, it is necessary to cool the electronic components. The imaging device described in Patent Document 1 includes an imaging element and a heat radiating component, and is configured to cool the imaging element by forcibly air cooling the heat radiating component. The imaging device described in Patent Document 2 is configured such that a cooling device is attached to the outside of the main body of the imaging device in order to forcibly air-cool the imaging device. In addition, some imaging devices are known that have an anti-vibration function that detects vibrations transmitted from the outside and cancels the vibrations based on the detection results. This anti-shake function allows you to record high-quality images.
- However, in the imaging device described in Patent Document 1, the area where the heat dissipation components are cooled is a limited area of a part of the casing, so it is difficult to sufficiently cool the image sensor . There is a risk. Furthermore, in the imaging device described in Patent Document 2 , there is a risk that the size will increase due to the attachment of a cooling device.
- The present invention has been made in view of the above problems. SUMMARY OF THE INVENTION An object of the present invention is to provide an imaging device that is miniaturized, can arrange a portion that can provide an image stabilization function for the imaging section, and can quickly cool an imaging element.
- Effects of the Invention
According to the present invention, while achieving miniaturization, it is possible to arrange a portion that can exert an anti-vibration function for the imaging section, and the imaging device can be quickly cooled.
