THine Electronics ISP for USB Camera Module

12/23/2017

THine Electronics is a well know company as "V-by-One" technology, but this "THP7312" is their first ISP (Image Signal Processor) chip targeting the applications like automotive and security camera.
The ISP product page describes,
​
"THine's ISP is an image processing engine for a digital camera. The pipelined image processing engine is possible to high speed processing. Auto Exposure / Auto Focus / Auto White Balance can be done by the special circuit. You can get the best picture quality in each CMOS sensor by using THine's ISP with our original noise reduction and gamma correction."
, and the chip supports MIPI® 2ch or parallel input and MIPI® 1ch or  parallel output to host.
​    * MIPI® is a registered trademark of MIPI Alliance, Inc.
It also has I2C master/slave, SPI master/slave, PWM, and GPIO signals to control image sensors and lens drivers as you can see the block diagram here.
They actually introduced the reference design of USB camera module in their website here.
This module uses 13MP image sensor and the basic spec is listed in the the link.
   ・Output resolutions and frame rate
     13M @21fps
     4K2K @30fps
     Full-HD(1080p) @60fps
     etc.
            *Maximum frame rate is 120fps
   ・Output format
            YUV422
            JPEG 
   ・Other key features
            Auto Exposure
            Auto Focus
            Auto White Balance
            UVC Video Processing Amplifier Properties (Brightness, Hue, etc.)
            LED Control
            Either USB3.0 or USB2.0
            Other UVC Standard Device Requests

It is quite nice reference design to start with.
I personally think it would be great if it can support stereo camera, but maybe using 2 of this design may allow you to do simple stereo camera concept design just adding the frame sync method although I am not sure if their chip is capable to do it.
If they can support thermal image sensor, it would be value adder, I think, and it would expand the application area.
