Abstract: A handheld device and system ins disclosed in which the device has a wide reading head with a narrow optical slot. The reader is used to read color patches on a target or the color output of a printer or other color reproducing device in which the colors to be measured are presented as a number of patches on a target. The light from the sensor is collimated and diffracted and focused onto a sensor for providing electrical signals indicative of the sensed patch. Repeated images of each test patch are taken and sent to the sensor. The output of the sensor is computed by on board electronics and an external computer to determine each color being measured.As indicated, light passes through a slot in the handheld device, is collimated and passed through a diffraction grating or prism so as to split the light into its spectral components and its position of its pixels with respect to the slot. The sensor is of the type found in a digital camera or similar means. Thus, the sensor provides signals which provide the spatial component in one direction, the spectral component in the other, and the intensity.Multiple images are taken of each colored patch. To calibrate the handheld device, the system calculates the spectral values and position of each pixel of a single-colored patch, converting these values into a grey scale and calculating the intensity and density of the light. This is then compared with pre-stored indicia to determine the accurate intensity level. A fully calibrated reader is then used to adjust the output of a color reproducing device, such as a color printer. It performs the same tasks of reading from the color target taken from the color reproducing device and matches the reflected output against stored values and calculates the provided signals to provide control signals to adjust the color reproducing device.
