ひかりメーター - 照度計

☀️ Just point your smartphone camera. A cute and easy-to-use light meter app.

"Is this room bright enough for studying or reading right now?"
"Is there enough light where I've placed my houseplants?"
When you need to know these things, simply point your smartphone camera and measure the brightness (lux) on the spot.

■ Useful in these situations:
・Checking the brightness of your study desk or workspace (500-750 lux recommended)
・A space for reading, crafts, and other detailed work
・Creating a suitable environment for houseplants or photography
・Visualizing the brightness of your bedroom or living room

■ Features
🎯 A semi-circular meter and large numbers show the current brightness at a glance
😊 Displays the brightness in easy-to-understand terms such as "Just the right brightness" and "Too bright!"
👆 Terms like ISO, shutter speed, f-stop, and EV are explained on the spot when tapped, making it easy even for beginners
🎚 Includes a calibration function. You can adjust the values ​​to match your accurate light meter, improving accuracy.
🔆 Supports a wide range of brightness levels, from bright outdoors to dimly lit indoors.
■ How the measurement works
This app calculates brightness from the camera's exposure information (ISO sensitivity, exposure time, aperture). Using the same principle as a photo exposure meter, it provides stable measurements that are less affected by screen color, etc.

■ Precautions
・Values ​​may vary depending on the camera model due to differences in camera characteristics. If accuracy is required, please use "Calibration K" to match your light meter.

・Please measure without covering the lens with your fingers, etc.

・This app does not save or transmit photos or videos externally. All processing is done within the device.

Let's measure the "brightness" around us with the cute sun! ☀️
