IMAGE TUNING

MINIMIZING THE COMPLEXITY OF ISP CALIBRATION AND IMAGE QUALITY TUNING FOR THE SMART EYES OF YOUR PRODUCT

overview

With over a decade of experience in camera design, and development, we offer image tuning, and optimization services to our customers around the globe. Our goal is to fine-tune camera products to achieve the best possible image quality for their intended applications. The cameras we design, develop and fine tune are currently being utilized in various fields including security and surveillance, automotive, action cameras, medical devices and consumer electronics.

We recognize that each combination of sensor, processor, and lens is unique, requiring careful processing and fine-tuning of captured images to attain the desired output. Our team has extensive experience working with a wide range of camera platforms, such as Qualcomm, Ambarella, NXP, TI, and sensors from reputable manufacturers like Sony, Omnivision, and Onsemiconductor.

ISP Tuning Lab Infrastructure

State of the art in-house image tuning labs equipped with latest equipment, specialized test charts and software tools enables us to fine tune the camera system ensuring optimum image quality as per the required use case and targeted application.

Image Signal Processing

3A system-level algorithm including Autofocus (AF), Auto Exposure (AE), and Auto White Balance (AWB) tuning
Image quality by eliminating unwanted dark or shaded edges.
3x3 color matrix method for color correction
Gamma correction and tone mapping to map one set of colors to another approximate the appearance of high-dynamic-range (HDR)

Imaging Laboratory

ISO resolution charts & color tests under controlled lighting
TE42 chart - noise, sharpness, subjective scenes, color, texture
Q13 chart/Q14 chart - visually detectable steps
Light Booth – to create different light conditions for sharpness & contrast
Kino Flo LED DMX Lighting - color temperature:- 2700K - 6500K
Macbeth ColorChecker - color fidelity, noise, AWB

Image Quality Subjective Analysis

Optimizing each stage of the Image pipeline for a particular application
Intensifying the image and video quality to be sharper and clearer with color accuracy.
Use of subjectively correlated image quality metrics and outlines a framework for camera benchmarking.
Noise reduction and other ISP parameters to deliver the optimum image quality.
