Claims12
A portable, detachable image reader for a photocopy machine including an optical-electrical sensor for producing a video image of the optical image to be recorded, a high intensity light source, a memory means for temporarily retaining the video image, and a battery energized power supply for energizing the sensor, light source, and memory means;
- the addition of sampling read-out means and display means for different spatial portions of the video image less than the entire image, thereby to indicate an estimate of the extent of hard copy reproducibility of the video image.
A portable detachable image reader for a photocopy machine including an optical-electrical sensor for producing a video image, a light source, a memory for "temporarily" retaining the video image, adjustable framing means for defining the area of the image to be copied, an adjustable optical system for focusing optical images of different size on the sensor, and means coupling the adjustable framing means to the adjustable optical system for automatically focusing images of different size.
