Which controller to take to transfer the image from the camera via Wi-Fi?

Question

Arduino

It is necessary to connect a camera, a Bluetooth module, Wi-Fi, a photoresistor to the controller. A resolution of 640×480 px is sufficient for the camera. You need to receive an image and send it to the server. It is enough to send several images per second.
For Arduino, there is a QV7670 camera module, but as far as I understand, with it it will either be extremely difficult to implement what was conceived at the proper level on Arduino, or completely impossible .. At the same time, it is desirable to reduce power consumption. The device will work 1 time per hour for 3 minutes. Powered by a removable battery.
UPD: it is enough to do only forward. Digital camera. There is no specific model, there is only a suitable resolution, and then the most suitable option for the controller.
Please advise the controller, on the basis of which you can optimally implement the above. Preferably, small controller size, low cost, and no more low-level programming than C/C++. Probably, one could take some kind of single-board computer (for example, raspberry pi) and not know the problems, but it seems to me that this is redundant.

Answer 1

Oh, this is about what I have been doing for almost 5 years at my job (we have been making wired and wireless endoscopes)
To transmit a picture via WIFI, it must be encoded, not a single MK can do this, but there are cameras that have a mode when they encode in JPEG themselves (not h264, and even more so not h265), but the FPS will sag. the camera cannot encode a lot and quickly, you will get 720p at about
10fps
write your own driver for the camera you chose from sony/onsemi/ov, asked the manufacturer for datasheets and, most likely, signed an NDA
It’s even more difficult to take some STM32 with its hardware DCMI and screw on an external WI-FI (although it’s easier for anyone, this option is easier for me)
Another level is to find a percent (I suggest ti or nxp, there are no more particularly open ones), and on it repeat everything that was foreseen above, you need to find the percent already at least with h246
Well, or take a plis, no comments here
The easiest option is to take raspberries

Answer 2

Look towards the ESP32-cam, based on the ESP32.
