A DSLR camera with two flippable imaging sensors

In today's world DSLRs commonly have one sensor in the camera body and if a need arises to use a different type of sensor for the same scene the photographer has to change the camera body on the lens. It also means that photographer needs to carry different camera bodies along with for different applications. With the use of this idea, a DSLR camera can incorporate two altogether different imaging sensors in the same camera body. The two imaging sensors are attached back to back and can easily be flipped to change places. These two imaging sensors can either be sensors of the same size (with different or same megapixel count) or of the different sizes.

One example could be having an APS-C size sensor and Full Frame sensor in the same camera body. There can be many combinations based on the different types of imaging sensors available in the market.

Fig 1 and Fig 2 represent a basic DSLR structure with following components

10 - A Lens which allows light to enter into the camera body
11 - A pentaprism/prism system prevalent in today's DSLR's
12 - A mirror assembly, which moves towards prism to allow light to be exposed to sensor
13 - Imaging Sensor 1
14 - Imaging Sensor 2
15 - Viewfinder of the camera
16 - A knob or a button to trigger the flipping of the imaging sensors

Basic Operation

Whenever a shutter is released in a DSLR camera, the mirror assembly (12) will go up allowing light from lens(10) to pass through & scene is evenly exposed on the sensor
(13) as shown in Fig 1. Now if a need arises to use a different sensor, A knob/button
(16) is provided, which when pressed will flip the two sensors to switch places. Imaging Sensor 2 (14) will come up in front & will function as main sensor & Imaging Sensor 1(13) will go to back as shown in Fig 2.

Here the idea is not to provide a replaceable imaging sensor but to provide two separate imaging sensors attached back to back which can flip places without opening/dismantling the camera body. It is also noted that the both the imaging sensors will be using the same camera hardware (processor, lens & other important hardware for the camera to function).


The main benefits of the idea are mentioned below
1.) Usage of two imaging sensors in the same camera body. Since the Imaging sensors are stacked back to back, it will not take up huge space like existing ideas, where imaging sensors are placed parallelly to each other.

2.) Hardware optimization - Same hardware will be used to capture image on both the sensors. Henc...
