Have you ever struggled with large file sizes when dealing with photos taken on your smartphone or images used on websites? That's where "image compression" comes in handy. This article explains the basics of image compression, its use cases, and the benefits of learning it. Master image compression and enjoy a more comfortable digital life! 1. What is Image Compression? Image compression is the process of reducing the file size of an image. Specifically, it reduces file size by reducing the number of pixels in an image or lowering the image quality. Why Compress Images? ・ Efficient File Transfer: When sending images via email or chat, large file sizes can take a long time or even prevent sending. ・ Improved Website Loading Speed: Large image file sizes on a website can slow down page loading, harming user experience. ・ Storage Space Savings: You can save storage space on your smartphone or computer. 2. Where is it Used? Image compression is used in a variety of situation...

We take photos with our smartphones and view images on websites… we interact with digital images every day. But have you ever deeply considered how digital images are represented? This article explains the basic concept of “image representation” in an easy-to-understand manner. We’ll introduce the mechanisms of image representation, its applications, and the benefits of learning it. Let’s step into the deep world of digital images together! 1. What is Image Representation? Image representation is the method of expressing information from the real world as digital data that can be handled by a computer. Simply put, it’s the mechanism of “how images are recorded and displayed by a computer.” Basic Elements of Image Representation: ・ Pixels: The smallest unit that makes up an image. They are small square dots. ・ Color: The color information held by each pixel. Commonly represented by a combination of RGB (Red, Green, Blue). ・ Resolution: The number of pixels contained in an image. The hig...

Have you ever heard the term “image correction”? It’s a technology that’s actually used in various aspects of our lives, such as filters in smartphone camera apps and retouching done by professional photographers. This article explains the basics of image correction, its use cases, and the benefits of learning it. Master image correction and enhance the expressive power of your photos! 1. What is Image Correction? Image correction is a technology that adjusts the color, brightness, contrast, and sharpness of digital images to make them easier to see and more appealing. Simply put, it’s “adjusting images.” Main Types of Image Correction: ・ Brightness and Contrast Adjustment:*・ Adjusts the overall brightness and difference between light and dark areas of the image. ・ Color Temperature Adjustment:*・ Adjusts the color tone of the image to be warmer (reddish) or cooler (bluish). ・ Color Correction:*・ Adjusts the balance of specific colors (red, green, blue, etc.). ・ Sharpness Adjustment:*・ ...

When you step into the world of image processing, you’re bound to encounter “binarization.” It might seem difficult… but binarization is a fundamental technique in image processing that leads to various applications. This article explains the mechanics of binarization, its use cases, and the benefits of learning it. Master binarization and expand your world of image processing! 1. What is Binarization? Binarization is an image processing technique that represents an image in black and white (two colors). The brightness of each pixel in the image is compared to a pre-set threshold value. Pixels with brightness above the threshold are represented as “white,” and pixels below the threshold are represented as “black.” It’s like creating a black and white photo. For example: ・ If the threshold is set to 128, pixels with brightness of 128 or higher are white, and pixels with brightness of 127 or lower are black. Binarization simplifies the image and has the effect of removing noise and empha...

“Image processing” might sound daunting to some. However, it’s a technology deeply integrated into our everyday lives.  This article provides a clear explanation of image processing fundamentals, its applications, and the benefits of learning it. Let's step into the world of image processing and explore its potential! 1. What is Image Processing? Image processing is a technology that involves performing various operations on digital images.  Simply put, it’s about “manipulating” images. Specifically, it involves performing the following operations: ・ Brightness and Contrast Adjustment: Basic processing to make images easier to see. ・ Noise Removal: Processing to eliminate unwanted points in an image and make it clearer. ・ Sharpening: Processing to emphasize the outlines of an image and make it appear more defined. ・ Color Correction: Processing to adjust the color tones and achieve a more natural look. ・ Image Scaling: Processing to change the size of an image. ・ Image Croppin...
