Camera Lens Communication Capability Storage and Host Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to accurately determine whether lens control is possible based on the lens mount, leading to incorrect menu displays for lens control items, as they do not consider the varying capabilities of different lens mounts.
Innovation Solution
An image capturing apparatus with a lens connection unit, host connection unit, and storage unit that determines and transmits whether communication with the lens is possible, using a storage region to set values indicating communication capability, allowing the host to determine lens control possibilities.

1Measurement precision
If conventional techniques are used to determine lens control capability, then the system maintains simplicity in information transmission, but the host cannot accurately determine whether lens control is possible, leading to incorrect menu displays
Solution Approach 1:
The camera performs preliminary determination of lens control capability before the host needs this information. The determination result is stored in advance in a storage unit, so when the host requests lens control capability information, the camera can immediately transmit the pre-determined result without performing real-time analysis, thus improving accuracy while maintaining simplicity
Solution Approach 2:
A storage unit acts as an intermediary between the lens connection unit and the host. Instead of the host directly analyzing complex lens mount characteristics or the camera performing real-time determination, the storage unit stores the determination result and transmits it to the host upon request, simplifying the information transmission mechanism while ensuring accurate capability determination

AI summary
There is provided an image capturing apparatus. A storage unit includes a first storage region for setting a value that indicates whether communication with a lens is possible. A determination unit determines whether communication with the lens is possible. A setting unit sets a value indicating that communication with the lens is possible in the first storage region in a case where it is determined that communication with the lens is possible, and sets a value indicating that communication with the lens is not possible in the first storage region in a case where it is determined that communication with the lens is not possible. In response to a request, which designates an address of the first storage region, from a host, a transmission unit transmits a value set in the first storage region to the host.
