Image resolution can be degraded by oversharpening, noise from the image sensor, and low megapixel counts. Megapixels refer to the total number of pixels in an image, and more megapixels allow for larger print sizes with better quality. Common causes of degraded resolution include oversharpening, which causes halos, and noise from the image sensor due to the physical properties of light and heat.

DSLR Technology
A digital single-lens reflex (DSLR) camera uses an interchangeable lens and digital imaging sensor similar to a film SLR camera. Key features of DSLRs include a mode dial, dust reduction system, interchangeable lenses, HD video capture, and a live preview. Digital photos are made up of pixels, and a camera's megapixel rating determines the maximum photo resolution and largest high-quality print size possible, such as an 8 megapixel camera allowing for a 12" by 16" print. However, a higher megapixel camera does not necessarily produce better quality prints than a lower megapixel camera for the same print size.
Glossary resolution
This document discusses image resolution and the factors that determine resolution. It explains that resolution is measured in pixels per inch (PPI) and describes the resolution of common cameras and images. Higher resolution images have more pixels and can capture more detail. The standard resolutions for print and screen display are listed. Image quality also depends on sensor size, as larger pixels can capture light more accurately.

Zooming and Its Types
Zooming enlarges images to make details more visible and clear. There are two types of zooming: optical zoom uses lens movement to magnify the image, maintaining quality, while digital zoom is image processing that crops the edges and compromises quality by expanding pixels. Optical zoom is achieved through physical extension of the camera lens, while digital zoom manipulates pixels after image capture.

The document discusses several key camera settings that impact photos:
1) Aperture controls the amount of light entering the camera and the depth of field, or how much of the photo is in focus. A larger aperture lets in more light but narrows the depth of field, while a smaller aperture lets in less light but increases depth of field.
2) Shutter speed determines how long the shutter is open, impacting motion blur and exposure. A fast shutter speed captures motion with less blur, while a slow shutter speed blurs motion but allows more light in.
3) ISO adjusts the camera's light sensitivity, with higher ISO numbers capturing more light but introducing more image noise. Lower ISO results in

Filters are processes that can be used to change the appearance of an image. There are two main categories of filters: corrective filters, which fine-tune aspects like color and sharpness without drastically altering the image's overall look, and destructive filters, which tend to obscure details and add special effects in a way that makes it obvious a filter was used. Photoshop contains over 100 different filters that are either single-step, applying with no options, or dialog box-based, allowing control over parameters. Smart Filters non-destructively apply effects above an image's original pixel data and can be re-edited or removed.

Chap26
Image resolution refers to the number of pixels per inch in a digital image. Higher resolutions allow for more detail but increase file size. When printing, a resolution of 300 pixels per inch (PPI) or higher is typically recommended. To modify an image's resolution, one opens the Image Size dialog box and changes the resolution value. However, increasing a low-resolution image's PPI does not actually add quality, and decreasing a high-resolution image's PPI results in quality loss. The steps also depend on the intended use of the image, such as web display versus printing.
Chap27
Image quality is determined by factors like sharpness, noise, dynamic range, tone reproduction, contrast, color accuracy and distortion. Sharpness refers to detail while noise is random pixel variations. Dynamic range is the light levels an image can capture. Tone reproduction is the relationship between scene luminance and brightness. Contrast affects loss of detail. Color accuracy and distortion can also impact quality. Software filters like blurring the background can improve an image's quality by making the subject stand out more, though they cannot add new detail. Frequency modulation screening randomly distributes dots to simulate gray levels and keeps dots the same size, varying frequency. It eliminates moiré effects seen with traditional screening. Higher resolution images, like 300 ppi versus 72
HA1 - Motion Graphics Now
Pixels are the smallest controllable elements that compose an image. When put together, pixels of varying colors blend to form the overall picture. The number of colors a pixel can display depends on its bit depth. Higher bit depths allow for more colors and higher quality images. Video and image resolution refers to the number of pixels and depends on factors like aspect ratio, frame rate, and video format. Compression reduces file sizes by discarding some image data using codecs, which can lower quality. Compositing combines separate visual elements to create a single image through layering and green screening.
Pixels
The document discusses key concepts in digital imaging including pixels, resolution, colour depth, aspect ratios, frame rates, video formats, video compression, and video compositing. It explains that images are made up of pixels which can only display one colour each but together form images. Higher resolution means more pixels per inch and clearer images. More colour depth allows more colours to be displayed. Aspect ratios and frame rates impact the shape and smoothness of motion in images. Video compression reduces file sizes by discarding some image data. Compositing merges separate visual elements into one scene.
2015 ipvm-ip-camera-fundamentals
This document discusses key concepts around video surveillance resolution:
1. Resolution traditionally referred to the ability to resolve details, but now usually refers to pixel count in surveillance cameras. Pixel count determines the potential quality, but other factors like low light performance also impact image quality.
2. Common resolutions for surveillance cameras include 1080p, 720p, 5MP, and 4K. Higher resolutions can capture more details but performance can vary depending on lighting conditions.
3. The sensor resolution may be higher than the maximum stream resolution available. Integrators also sometimes set cameras to stream at lower resolutions than maximum.
4. Compression greatly impacts resolution - high compression can significantly reduce bandwidth needs but also impact visible image quality
Basic Image Editing, Part 3
This document discusses image selection and editing. It defines what an image is, including two-dimensional photographs and three-dimensional statues. It describes how images can be captured optically or manually rendered. The document then discusses image editing, both traditional analog techniques like photo retouching as well as digital editing software. It explains how image size refers to resolution in pixels and megapixels. Compressed file formats like JPEG can reduce file size but also decrease image quality the more an image is compressed. The document concludes by defining resolution and pixel resolution, noting that smaller pixel sizes capture more image detail for higher resolution.
Best Practices To Improve Your Digital Photographs
This presentation was originally written to accompany a lecture and demonstration so you may find some of this a bit "off". Power through it and see what you can take from it.
Digital Cameras
Digital cameras come in various types for different needs and budgets, including point-and-shoot cameras which are small, light, and inexpensive; prosumer cameras which are more versatile with some professional features; and professional SLR cameras which provide better image quality but are bulkier. Key components of digital cameras include the lens, which focuses light onto the image sensor, and the sensor which converts light to electric signals to create digital photos. Image quality is affected by the lens quality and zoom range, sensor resolution and size, and settings like ISO which controls light sensitivity. Buyers should consider specifications like these as well as features needed for their intended use.
Understanding Raster Graphics
Bitmap graphics are composed of grids of pixels that are each assigned a color value and stored numerically. Higher resolution images have more pixels and thus more detail but also larger file sizes. Compression reduces file size by removing some pixel data, with JPEG being best for photos and GIF for simple images. Common file formats include TIFF, EPS, JPEG, GIF and PDF, with the appropriate format depending on the image content and intended use.
Digital Cameras Sponsored
Digital cameras come in various types for different needs and budgets, from cheap point-and-shoot cameras to expensive professional SLR models. Key components that impact image quality include the lens, image sensor, and image stabilization system. Camera lenses use different elements and apertures to focus light onto the sensor, and features like zoom range, aperture sizes, and sharpness are important. Larger image sensors generally produce higher quality images but increase camera size and cost. Other factors like resolution, noise, ISO light sensitivity, LCD screens, and manual controls allow photographers flexibility in shooting styles and environments. Understanding these core camera technologies helps choose the right camera.
Glossary
Pixels are the smallest controllable elements that make up images on digital displays. Each pixel can only display one color and more pixels allow for more colors and higher resolution images. Resolution refers to the number of pixels per inch in an image, with higher resolutions allowing for larger printed photos without quality loss. Aspect ratio describes the width-to-height ratio of screens or images. Frame rate is the number of unique, consecutive images or frames displayed per second in video and film. Common video formats specify elements like the codec, frame rate, size and aspect ratio.
What is spatial Resolution
Spatial resolution refers to the ability to distinguish between two close objects or fine detail in an image. It depends on properties of the imaging system, not just pixel count. Higher spatial resolution means finer details can be distinguished. Pixel count alone does not determine spatial resolution, as color images require interpolation between sensor pixels. Spatial resolution is measured differently for various media like film, digital cameras, microscopes, and more. It affects the ability to distinguish fine detail like gaps in a fence as distance increases.

Resizing Photos Simplified
Digital images are composed of pixels arranged in a grid, with each pixel represented by values for red, green, and blue light. The resolution of an image refers to the number of pixels per inch, which impacts the level of detail visible. Image size is measured by the number of pixels, while resolution impacts the physical size at which the image can be printed clearly. The appropriate resolution depends on the intended use of the image, such as printing, viewing on screen, or sharing online.

DIGITAL IMAGE PROCESSING.docx
Digital image processing involves converting analog images to digital format using techniques like sampling and quantization. Sampling converts continuous images to discrete pixel values that define the image's spatial resolution. Quantization divides signal amplitudes into quanta to derive values that determine image quality. Together, sampling and quantization are key to converting images to digital format and improving qualities like sharpness, brightness, and clarity.
Computer image
Bitmap images are made up of grids of pixels and are resolution dependent, so they can lose quality when resized. Vector images are made up of mathematical lines and curves, so they are resolution independent and can be resized without losing quality. The document explains bitmap and vector images, and discusses how image size, resolution, and pixel dimensions relate to on-screen display and print quality. It provides guidance on preparing images for different mediums like web, print, and video.

Chap28
- 1. Outline the steps to determine image resolution.
- 2. In This Chapter, you’ll learn on: Identify processes which lead to degrading of image resolution and quality. Utilise imaging software to adjust an image resolution.
- 3. Degrading of image resolution and quality Sharpness is not doubt one of the factor for good quality image, and despite that lost sharpness can be restored by sharpening, Oversharpening, on the other hand can degrade image quality by causing "halos" to appear near contrast boundaries. Images from many compact digital cameras are oversharpened.
- 4. When an image is capture by the device, noise arises from the effects of basic physics— the photon nature of light and the thermal energy of heat— inside image sensors. Typical noise reduction (NR) software reduces the visibility of noise by smoothing the image, excluding areas near contrast boundaries. This technique works well, but it can obscure fine, low contrast detail. As we learn that an image is compose of dots, called pixels. The image that you see is created out of millions of pixels: hence, megapixels. Hence, Megapixels is the total number of pixels captured by an image sensor. Therefore a low quality image sensor is also an factor for the degrading of the image resolution
- 5. Megapixels and Print Size This table shows the relationship between camera megapixels, horizontal and vertical pixels in the image, and the size of a print at 200 pixels per inch. MEGAPIXELS IMAGE SIZE (PIXELS) PRINTED SIZE (INCHES) * 2.0 1224 x 1632 6.1 x 8.2 3.0 1536 x 2048 7.7 x 10.2 4.0 1704 x 2272 8.5 x 11.4 5.0 1944 x 2592 9.7 x 13.0 6.0 2048 x 3072 10.2 x 15.4 8.0 2236 x 3504 11.2 x 17.5 * The printed size is determined by dividing the horizontal and vertical pixels by the pixels per inch.
- 6. When your image capturing device has more megapixels, you get large size prints even if you print with lots of pixels per inch. You can always print using fewer pixels per inch to increase the size of your photographs, but image quality will suffer.
