Abstract:Abstract-The image sensor in the optical mouse reads the scene of the bottom, and compares it with the last sceneto acquire the moving data. The scene should be read with high frame rate to make the moving of the cursor soft and exact. The high frame rate means the short time to integrate the signal charge. The weak signal causes malfunctioning of the moving of the cursor. The signal should be amplified to ensure the signal to noise ratio. Some type of the pixel in the optical mouse uses a bipolar transistor t… Show more
