Raspberrypi high res camera

The simplest option to getting higher res cameras to work with the RPi would be to use either:

a. IP Based camera with the desired resolution

b. USB Camera compatible with RPi

c. If on a budget, use an android phone with the IP Camera App

The basic problem with using the USB option would be drivers and compatibility and then the processing horsepower needed to crunch that kind of data.

Hope this help.

The basic issue is that the camera interface requires specific sensor-support in software on the raspberry pi. As that part of the software runs on the video core, we have to rely on the raspberrypi.org guys to create support for a sensor. There is just one sensor supported right now, the 5MP one.

Products like "usb cameras" are usually meant for video conferencing. So they focus on full-hd video at the best. They might have a 5Mpixel sensor like the raspberry pi camera, but not any more.

Many digital cameras have "gphoto2 support". Some of them allow remote capture. Maybe that will do what you want?

If you have a SDLR camera with high resolution quality, e.g. the Canon 600D, Canon Rebel 2i providing jpeg and raw formats up to 16 and 18 Mp or - probably nearest your needs - the old model 400D with 14 Mp you can control the camera with several platforms including Linux.

In this case the approach is slightly different than a camera sensor (like the one of the Raspberry PI) attached with some kind of fast bus to the board but you will use some GPIO pins to manage the camera controls (flash shooting, autofocus, follow focus etc. Then via the USB you can access further camera features with a protocol that does not need of drivers as you send commands directly to the camera via the USB like aperture and exposition time and more.

All these things figured in this scenario exclude the physical acquisition of the ima that is stored on the camera memory; Canon control also gives the option to acquire images to an external storage attached to the controlling device (in this case the Raspberry PI, but I think that the processor speed and other factor makes it only theory). The images acquisition can be done independently by the shooting phase so a further alternative is to control and set the shooting all automatically then acquire the image - slowly - in a second moment to store somewhere on an external storage support.

Instead of a DSLR you can use one of the GoPro high resolution model (from model 3) including the WiFi access to the camera from the Raspberry PI to control the entire pre and post shooting process. Also in this case you are obviously subject to the limitations mentioned above for the DSLR cameras.

This is in my opinion, the only possible scenario you can think to access with great results to control the camera but not more. The following is an example of a video I have done with the first prototype of this kind; in this case it was just only a 8 bit microcontroller managing the entire system with - IMHO - good results. The next step I am working to is a full hardware control of DSLR camera (I have not a proper usable GoPro, just only a very ancient first model) using the Raspberry PI in one case and the Educational Boosterpack MKII with the MSP432 launchpad board from TI in another. These are two different kind of applications involving also some strong synchronised camera motion control.

Yep, you can either try the standard USB cams with the high res sensors (Not sure if they are real pixels) or you can use any number of DSLRs and remote tether them. In fact you can even get the microscope compatible cameras that look like security cameras and have C mount lenses and also work as standard UVC  Linux drivers.

I have a Cannon 600D attached to my PC  that works fine with the Tether apps available for Linux
