TTL Serial Camera Created by lady ada Last updated on 2019-11-01 08:44:02 PM UTCOverview This tutorial is for our new TTL serial camera module with NTSC video output. These modules are a nice addition to a microcontroller project when you want to take a photo or control a video stream. The modules have a few features built in, such as the ability to change the brightness/saturation/hue of images, auto-contrast and auto-brightness adjustment, and motion detection. Since it is a little confusing how this is both a snapshot and video camera, we d like to explain it in detail now. The module was initially designed for surveillance purposes. Its meant to constantly stream TV-resolution video out of the Video pin (this is NTSC monochrome format) and also take commands from the serial port. The serial port commands can request that the module freeze the video and then download a JPEG color image. So for example, normally its just displaying video to a security monitor. When motion is detected, it would take a photo and save it to a disk for later analysis. The module is admittedly not extremely high resolution - the maximum image size it can take is 640x480 pixels. And it is sensitive to infrared light, which alters the color rendition somewhat. The reason for all this is that it s meant for surveillance, not for nature photography. However, as far as we can tell, this is the best module on the market. Module size: 32mm x 32mm Image sensor: CMOS 1/4 inch CMOS Pixels: 0.3M Pixel size: 5.6um*5.6um Output format: Standard JPEG/M-JPEG White balance: Automatic Exposure: Automatic Gain: Automatic Shutter: Electronic rolling shutter SNR: 45DB Dynamic Range: 60DB Adafruit Industries
