Webcams have become increasingly popular in recent times, primarily due to the rise of remote work and video conferencing. However, not many people understand the technical specifications that determine the quality of a webcam. In this article, we will explore some common misconceptions about these technical specifications and help you make a more informed decision when purchasing a webcam.

One of the most common misconceptions about webcams is that a higher resolution always translates to better image quality. While it is true that a higher resolution camera can capture more detail, the image quality also depends on factors such as sensor size, lens quality, and image processing software. A lower resolution camera with a high-quality sensor and lens can produce a better image than a higher resolution camera with poor-quality components.

Additionally, higher resolution cameras require more processing power and bandwidth to transmit the video, which can result in buffering and lag if the internet connection is not strong enough. Therefore, it is essential to consider all aspects of a webcam's technical specifications before making a purchase.

Resolution and megapixel are related terms, but they refer to different aspects of image quality.

Resolution refers to the level of detail or information that an image contains, usually measured in terms of the number of pixels in the image. For example, a 1920x1080 resolution image has 1920 pixels horizontally and 1080 pixels vertically, for a total of 2,073,600 pixels (or 2.07 megapixels).

Megapixels, on the other hand, refers to the total number of pixels in an image sensor or camera, and is usually used to describe the size or quality of a digital camera. For example, a camera with a 16-megapixel sensor is capable of capturing images with a resolution of 4,608 x 3,456 pixels.

In short, resolution refers to the actual number of pixels in an image, while megapixels refer to the number of pixels that the camera or image sensor is capable of capturing.

The image below compares the picture quality of Logitech C920 (2.0 MP), ideaCam (8.0 MP), and Facecam (4.0 MP). ideaCam produces better picture quality than a 1080P video environment, despite having the same resolution.

Most webcams boast high-definition quality, but only support 1080p resolution. Even if they have 4k resolution, they often have low specs and only 2 to 4 million pixels. ideaCam is different because it has an 8 million-pixel Sony CMOS camera with 2448p resolution and a 4:3 aspect ratio, and 4k level image quality. This means it has twice as many pixels as common webcams with 4 million pixels, resulting in clearer images with better detail.

ideaCam is perfect for video conferences as it can capture objects with more clarity and provide high-quality video.

Another common misconception is that a wider field of view (FOV) is always better for a better viewing experience. However, a wider FOV can lead to distortion and a loss of detail around the edges of the frame.

To make sure you get the best outcome, it's important to choose a webcam with an appropriate FOV that suits your needs. For video calls with 1-2 people, a FOV of 75°-90° is enough. For group meetings, a wider angle of 120° is better. If you need to capture physical objects without distortion, a FOV of around 75° is ideal.

ideaCam is mounted at a height of 27-32 inches on the screen, making it easy to capture paper sizes ranging from A4 to A3.

The camera's 3A functions - Auto Focus, Auto Exposure, and Auto White Balance - significantly contribute to its overall image quality. Although most webcams have automatic settings that adjust these functions based on the lighting conditions in the room, relying solely on them can lead to poor image quality in certain situations, such as low light or backlighting. Let's take a closer look at each function:

Modern cameras have different exposure metering modes that help adjust camera settings automatically for the best exposure. There are three main modes :

ideaCam uses center-weighted metering to adjust the exposure. It focuses on the central area of the frame and adjusts the exposure based on its brightness and contrast. This helps to avoid overexposure or underexposure in backlit environments, resulting in clearer and more natural images with better exposure when capturing a portrait or an object.

This function automatically adjusts the camera's focus to capture the clearest image. It uses either optical sensing or contrast detection. Unlike most webcams that offer only one focus mode, ideaCam can switch between auto and manual focus modes when used with its software, EnSpire. It can even switch modes automatically by flipping the camera. When flipped to the desktop view, it switches to fixed mode to avoid continuous focusing on your hand, thus preventing blurriness when presenting objects during video calls.

This function helps to ensure that colors are accurately represented in photos. Different light sources have different color temperatures, and if the camera doesn't adjust for these differences, the colors in the photo may look off. White balance compensates for these differences to make sure that colors look natural and accurate.

Are you confused about webcam technical specifications? If so, we hope this article can help you to find the best webcam for your virtual meetings. Consider BenQ ideaCam for an improved remote work experience as it offers advanced settings for clear and accurate images of both portraits and objects in any lighting condition.
