Monday, January 16, 2023, 10:40AM – Image Quality and Systems Performance (IQSP) Conference

The global impact of camera phones is multi-faceted, influencing technological advances, user interface design, cloud storage, and image sharing methodologies.  The sheer volume of camera phone ownership has dwarfed the existing number of digital still cameras as the camera phone market segment grew from tens of millions in early acceptance years in Japan to annual global sales volumes of over 1 billion for nearly 10 years and counting.  This has enabled and pushed forward revolutionary image quality advancement of the incorporated cameras in the multifunctional devices, progressing from 0.11MP image sensors with 2-inch displays in 1999 to current maximums of 200 MP sensors and 8-inch foldable displays.  This overview will provide example images and image quality metrics showing the progression over the past twenty years.  Content will also highlight significant technological advancements impacting image quality attributes such as resolution, low light performance, dynamic range, zoom, and bokeh.

Monday, January 16, 2023, 11:20AM – Image Quality and Systems Performance (IQSP) Conference

We describe a new calculation of camera information capacity, C, derived from standard 4:1 contrast ratio slanted edges, that takes advantage of an overlooked capability of the slanted edge that allows the variance and hence the noise of the edge to be calculated in addition to the mean. The average signal and noise power derived from the edge can be entered into the Shannon-Hartley equation to calculate the information capacity of the 4:1 edge signal, C[4]. Since C[4] is highly sensitive to exposure, we have developed a more consistent metric, C[max], derived from the maximum allowed signal in the file, making it an excellent approximation of the camera’s maximum information capacity. Information capacities C[4] and C[max] are excellent figures of merit for system performance because they combine the effects of MTF and noise. They have great potential for predicting the performance of Machine Vision and Artificial Intelligence systems. They are easy to calculate, requiring no extra effort beyond the standard slanted-edge MTF calculation.

Tuesday, January 17, 2023, 12:00PM – Autonomous Vehicles and Machines (AVM) Conference

Stray light (also called flare) is any light that reaches the detector (i.e., the image sensor) other than through the designed optical path. Depending on the mechanism causing stray light, it can introduce phantom objects (ghosts) within the scene, reduce contrast over portions of the image, and effectively reduce system dynamic range. These factors can adversely affect the application performance of the camera and, therefore, stray light measurement is to be included in the upcoming IEEE-P2020 standard for measuring automotive image quality. The stray light of a camera can be measured by capturing images of a bright light source positioned at different angles in (or outside of) the camera’s field of view and then processing those captured images into metric images with associated summary statistics. However, the setup and light source can have a significant impact on the measurement. In this paper, we present lessons learned and various technical elements to consider for stray light (flare) testing of digital imaging systems. These elements include the radiometric (e.g., brightness) and geometric (e.g., size) qualities of the light source and setup. Results are to be presented at the conference.

Wednesday, January 18, 2023, 5:30PM to 7PM – Imaging Sensors and Systems 2023 Interactive Papers Session

The EMVA 1288 Standard offers a unified method for the objective measurement and analysis of specification parameters for image sensors, particularly those used in the computer vision industry. Models for both linear and non-linear sensor responses are presented in the version 4.0 release of the standard, and are applied in the characterization of a commercial DSLR camera sensor. From image capture to analysis, this paper details the equipment, methodologies, and analyses used in the implementation of the latest standard in a controlled lab setting, serving as both a proof of concept and an evaluation of the presentation and comprehensibility of the standard from a user perspective. Measurements and analyses are made to quantify linearity, sensitivity, noise, nonuniformity, and dark current of the chosen sensor, according to the methods laid out in the EMVA 1288 standard. This paper details the realistic implementation of these processes in a controlled lab environment and discusses potential flaws and difficulties in the standard, as well as complications introduced by nonideal experimental variables.

Reducing the cross-lab variation of image quality metrics

Henry Koren
 
As imaging test labs seek to obtain objective performance scores of camera systems, many factors can skew the results. IEEE Camera Phone Image Quality (CPIQ) Conformity Assessment Steering Committee (CASC) working group members performed round-robin studies where an assortment of mobile devices was tested within heterogeneous imaging labs. This paper investigates how the existence of near-infrared energy in light sources that attempt to simulate CIE illuminants can influence test results. Numerous other impacts, including the influence of opal diffusers used for uniformity testing, how test scene framing can alter white balance and exposure, and how chart quality and texture frequency distribution can skew results. We introduce a test procedure which is intended to reduce intra-lab variability and a method for assessing an independent lab’s competence in conforming with the IEEE testing standards.

Compensating MTF measurements for Chart Quality limitations

Norman Koren
 
Objective measurements of imaging system sharpness are typically derived from test chart images. It is generally assumed that if testing instructions are followed—if the chart print quality is fine enough and the chart magnification (on the sensor) is low enough—  test chart quality will have little impact on the overall measurement.
 
This assumption may not be valid when extremely high-resolution cameras are tested with standard charts or when smaller than optimum test charts are used because of laboratory or production line space limitations.
 
MTF compensation is applied by dividing the measured system MTF by chart-projected MTF as a function of the sensor.
  1. Measurements made under different conditions— with different test charts (transmissive as well as reflective) by different people in different labs— are more consistent.
  2. The megapixel suitability of test charts is increased by a factor of approximately 2 (1.4x linearly).
  3. The key advantage of MTF compensation is that measurements are more accurate (in an absolute sense).
