摘要： PURPOSE:To efficiently store and retrieve a picture by applying a marking to plural specific pictures selected from the plural pictures, storing and initially staring a retrieval from the specific picture based on the marking. CONSTITUTION:A storing means (a) applies the marking to the specific plural specific pictures (representative picture) selected from the plural pictures and stores together with the selecting information of the specific picture. In a retrieving means (b), the retrieval is initially started from the specific picture based on the marking, and a picture (slave picture) subordinate to the specific picture detected by the retrieval is outputted. In such a way, the branch structure of the representative picture and the slave picture is associated and stored to retrieve, so that a desired picture can be easily extracted with an extremely simple operation.

摘要： PURPOSE:To obtain sufficiently accurate information from a middle and to obtain rough information from circumferential parts. CONSTITUTION:An image pickup range of an image pickup element is divided into plural image pickup ranges, and a picture element pitch is formed in details for a photosensing section A1 of an image pickup range 1a provided in the middle to obtain picture information with high accuracy. Then the picture element pitch is formed rough to a photosensing section A3 of image pickup ranges 1c formed to the circumferential part and number of picture elements is decreased to be a required minimum value and rough picture element data are obtained from the circumferential part. Thus, high speed arithmetic operation is attained by fetching picture information with a low space frequency in a form with less reflection.

摘要： PURPOSE:To allow the automatic and inexpensive formation of multicolor images formed by color sepn. of the specific color image of a multicolor original with simple constitution by controlling eraser processing by digital exposing systems to the specific wavelength region in the original in parallel with read exposing of the multicolor original. CONSTITUTION:Only the light of the specific wavelength region in the luminous fluxes obtd. from analog scan exposing systems 2 to 5 is separated by a 1st color separating means and the reflected image entering via the 1st color separating means 8 is read by an image reading means 6. While the light of the specific wavelength region in the luminous fluxes obtd. from the analog scan exposing systems 2 to 5 is separated by a 2nd color separating means 7, the multicolor original images are formed on a photosensitive body 15. The irradiation of the photosensitive body 15 with a light beam by the digital scan exposing systems 9 to 12 is controlled in accordance with the output of the image reading means 6 and the region off the specific color region which can be separated in color by the 1st color separating means 8 is erased at the time of copying processing of the specific color which can be separated in color by the 1st color separating means 8 in an erasing means 52. The multicolor images formed by the color sepn. of the specific color image of the multicolor original are inexpensively and automatically formed with the simple constitution in this way.

摘要： PURPOSE:To improve picture quality by adding a burst signal, which has the same phase as the sampling phase of a picture signal and is amplitude-modulated according to a track position, to the partial period of the picture signal and recording the picture signal. CONSTITUTION:Picture signals, to which identification burst signals to synchronize with a sampling clock are added, are outputted through still video recording process circuits 110 and 111 to adders 112 and 113. On the other hand, pilot signals to be generated from a pilot signal generator 120 synchronously with a sampling clock to be outputted from a clock generating part 119 are supplied to the adders 112 and 113, these pilot signals are added to the identification burst signals from the adders 112 and 113, amplified in recording amplifiers 114 and 115, after that supplied to magnetic heads 116 and 117, and recorded in a video floppy 118.

摘要： PURPOSE:To record and reproduce information other than an image signal by recording a carrier signal modulated by an information signal other than the image signal together with the image signal on at least adjacent two tracks, and recording a pilot signal of single frequency together with the image signal on at least one track. CONSTITUTION:The carrier of an ID signal is recorded on the track A in a non-modulates state, and it is recorded on the track B in an ID encoder 11 in a DPSK-modulated by information data. When the signals of the picture elements of lines C and D are recorded, the carrier of a DPSK-modulated ID signal is recorded on the track C together with the image signal in the ID encoder 11 based on the information data, and only the carrier of a non- modulated ID signal is recorded on the track D together with the image signal. Thus, a frame image can be reproduced similarly as an on-going image even in a reproducing device corresponding to an on-going SV format in a video floppy recorded in such way.

摘要： PURPOSE:To eliminate shock due to pressing or detach of a solder iron and to reduce the deviation of position at heating and cooling of solder by forming the tip of the solder iron for heating as a rod and cutting of the rod tip after heating/cooling/solidifying. CONSTITUTION:When a current flows to a heater 5 at first, a cream solder 4 is started molten. At that time, the position of a soldered part is minutely moved, but it is corrected by moving slightly the position of a support member 8 while utilizing a piezoelectric element or the like. At interruption of the current of the heater 5, the solder 4 starts solidifying, but slight correction is exerted similarly before the solder is completely solidified. When the solder is cooled completely, the solder is solidified and fixed. A thin rod heat needle 6 is cut off finally after the solidification. The heat needle 6 is made of a tin plated copper wire or the like, which offers lase of cut-off so as not exert a large shock to a solidified part.

摘要： PURPOSE:To form an image in an only arbitrary area of an original by specifying the area of the original based on the position of an image having specific wavelength light read by a photographing means, and driving and controlling a second exposing means in order to remove a latent image in the specified area or an area other than that before starting a developing process. CONSTITUTION:A desired area of the original 1 is enclosed by using such a pen having a specific color which corresponds with the specific wavelength of a specified-image reading means 6. Then, a latent image is formed by exposing the original 1 onto an image carrier 15 with a first exposing means 2 of an image analogue exposing system. At the same time the specified-image reading means 6 recognizes the area enclosed with the specific color pen; the latent image inside or outside the area is selectively removed by exposing the latent image on the image carrier 15, corresponding to the image inside or outside the area, with the second exposing means 9. Therefore, the only desired image is developed.

Moreover, a recording means inputting the 1st pickup picture signal and the 2nd pickup picture signal and recording the 1st pickup picture signal and the 2nd pickup picture signal on separate areas provided on the recording medium is provided. Thus, the broad band picture signal is recorded on the recording medium without deterioration.

摘要： PURPOSE:To effectively use a luminous flux of a laser light source and to execute a scan by a beam waist diameter required on the surface to be scanned by using a retrofocus type as a collimator lens for obtaining a parallel luminous flux from a luminous flux of the laser light source, etc. CONSTITUTION:A collimator lens 3 is constituted of a retrofocus type. That is, a light beam I which is emitted from a light source 2 passes through the collimator lens 3, is reflected by the reflecting surface 1a of a rotary mirror 3, and next, by the reflecting surface 1b, becomes a reflected light beam R and passes through an (f)theta lens 4, is reflected by a mirror 7 and reaches on the surface to be scanned A. Subsequently, when the rotary mirror 5 rotates centering around a rotation axis 6, a scanning line is drawn in the direction vertical to the paper surface on the surface to be scanned A. In such a way, a luminous flux from a laser is used effectively without using a light source of a laser of a high output, etc., and also, a scan can be executed by obtaining the beam diameter required on the scanning surface (image forming surface).
