Keyence calls 2 mega-pixel mode a 'first'

By automatically shifting the 1-million pixel target area, the camera can use the full 2-million pixel image to perform inspections, widening range and increasing speed, says Keyence of its CV-2100/2600 line. (2600 is shown.)

's CV-2100/2600 machine vision cameras claim a number of industry firsts, including high-speed enhancement with 1 and 2 mega-pixel modes and highly sensitive image capturing, with an 81-level span/shift function.

The 1 mega-pixel mode cuts an area of 1-million pixels from the 2-million-pixel CCD, improving speed and accuracy for better support of high-speed production line applications, Keyence says. Higher resolution with same field of view is said to augment measurement accuracy; wider range with same precision per pixel can avoid necessity of mounting multiple cameras. Combination of sub-pixel processing and digitalization of image data allows the CV-2100 to achieve high accuracy and repeatability down to0/2600 will average multiple images providing stable and reliable data. Image data captured onto the CCD is converted to digital data within the camera unit and then transferred to the controller. As a result, the image will not deteriorate and is resistant to noise interference.

Camera sensitivity can be adjusted in 81 levels. Setting a higher sensitivity ensures sufficient brightness even while the high-speed shutter is used, eliminating need for strobe lighting. Span/shift function increases the difference in the contrast of low-contrast targets, ensuring more stable image processing. A 360° rotation search uses normalized correlation (for stability in poor lighting conditions) and enables a real-time search with a minimum speed of 61 ms. CV-2600 can be focused on the area of interest, 100 lines, decreasing process time to 12 ms.
