Variation of response between pixels with same level of input illumination. Resolution Usually the amount of pixels in the camera sensor; for example, RM-340/341 has a 640 x 480 pixel sensor resolution. In some occasions the term resolution is used for describing the sharpness of the images. Issue 1 COMPANY CONFIDENTIAL Page 5 –5...
