Abstract: A camera-type image input apparatus comprises a light-receiving element disposed in a light-receiving area for receiving light from an object through a lens, and light-emitting elements disposed in the light-receiving area to irradiate the object through the lens. Since the light-emitting elements disposed in the light-receiving area irradiate the object through the lens to have an irradiation pattern formed on the object, a user can perform viewing and focusing based on such an irradiation pattern. Hence, viewing and focusing can be performed efficiently, and distortion-free pictures can be taken.

Abstract: A lens is provided for converging rays reflected from an object, and a line sensor is provided for receiving rays converged by the lens. The line sensor has a plurality of photoelectric conversion elements corresponding to predetermined pixels of one line. White level correction data are obtained for correcting a deviation of an output signal of each photoelectric conversion element from a standard value, and plane correction data is obtained for correcting unequal distribution of quantity of light dependent on the lens. An output signal of the line sensor is corrected with the white correction data and the plane correction data.

Abstract: A video disk player generates an error control signal according to the difference between write and read addresses, and causes a read clock to be synchronized in phase with a write clock, on the basis of the error control signal upon reception of an external video signal instead of a video signal produced by playing a video disk, thereby always keeping constant the difference between both addresses.

Abstract: An image processing apparatus generates an after-image effect by using a first memory in which one field of digital composite video signal selected from every 4 fields is stored successively and a second memory in which one field of the digital composite video signal which is the same as any one field of the field group stored in the first memory is stored successively, and combining the field outputted from the first memory and the field output from the second memory together. An image processing method according to the invention includes the steps of dividing a picture into a plurality of regions, writing image data of each point of the plurality of regions into each corresponding memory locations of a memory only during periods selected, for each of the plurality of regions, from periods of the cycle of four fields.

Abstract: A signal regeneration processor which carries out dropout correction for a signal by replacing a prescribed number of low-order bits of a signal obtained by delaying a digitized regenerated signal by a prescribed length of time, with a prescribed code in accordance with a dropout detection signal, and then by writing the signal in a signal processing memory according to the prescribed code contained in the data read from the memory. Since it is possible to confirm in advance the occurrence of a dropout on the reading side of the memory and to carry out dropout correction by address manipulation of the memory, a line memory for replacing a video data at the time of dropout correction can be eliminated.

Abstract: A video processing system in which data obtained from sampling an input video format signal according to a first timing signal is written into a first memory according to the first timing signal. Data is read-out of the first memory according to a second timing signal having a frequency equal to N times that of a horizontal synchronizing frequency of the input signal, thereby obtaining data with no time-base fluctuation. M-samples of data from the first memory is then written into a second memory, and data from the second memory is read-out such that the read-out signal from the second memory has a different phase than that of the input video format signal. The system is operable for simultaneously stopping data being read-out of the first memory and data being written into the second memory for a period of time equal to R+kM samples of the input video format signal, wherein R is an integer remainder of N/M, and k is either a positive integer or zero.

Abstract: Excess coating material removed from a coated web 1 by an air doctor 6 and entrained in the exciting gas mixture flow 8 is directed along a plate 9 to effect primary coating material separation and recovery in a chamber 11, whereafter the flow passes along an inwardly spiraling apparatus wall 14 which terminates in an air exhaust duct 16. The wall 14 initially continues the prolongation or extension plane of the plate 9, and includes secondary recovery chambers 13 and 15, whereby separation is implemented by both centrifugal and gravitational forces. The same concepts may also be used to recover solid particles in a surface abrasion apparatus such as a sand blaster.
