Cameras, waterproof digital cameras There are many types of cameras, and their basic working principles are the same: convert optical image signals into electrical signals for easy storage or transmission. When we photograph an object, the light reflected on the object is collected by the camera lens, focused on the light-receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electrical energy through the camera device, that is, we get "Video Signal". The photoelectric signal is very weak and needs to be amplified by a preamplifier circuit, and then processed and adjusted by various circuits. The final standard signal can be sent to a recording medium such as a video recorder for recording, or it can be transmitted through a propagation system or sent to a monitor Show it. Facing an industry market with such great development potential, establishing a brand and facing the market starts with brand and trademark registration.

Therefore, among the 45 trademark categories, which category does the camera trademark registration belong to? Which category does the camera trademark registration belong to? Inquiring in the classification table, we learned that the camera belongs to Category 9 Scientific Instruments 0908-Audio and Video Equipment 090630: Camera C090033: TV Camera requires full or multi-category trademark registration. Relevant companies must choose the correct trademark based on the specific goods or services sold. category.
