摘要： The position of the same point on each of the images of a single object formed by the imaging means of an endoscope is detected, and shift maps between the respective images are formed using the detected positions. Each of the imaging positions of the imaging means is estimated from the shift maps, and a relative shape of the object is then estimated from the imaging positions. Since a relative shape of the object is estimated using the correlation between the respective images, a relative shape of the object can be estimated even when not only the imaging means but also the object are moved. An absolute shape of the object can also be estimated using a length as a reference value.

摘要： There is provided a frozen picture memorizing memory holding as a frozen picture image a picture image signal imaged by an electronic endoscope. By the operation of a frozen picture directing switch, whether the frozen picture is adapted to the memorizing condition or not is judged through a picture image movement detecting circuit. In case it is judged to be adapted to the memorizing condition, the picture image signal is memorized actually as a frozen picture image to obtain a clear frozen picture having little color smear and fogging.

摘要： An image sensing system comprises photoelectric conversion element array which responds to the light from a subject and produces charges responding to the quantity of incident light, storage parts temporarily storing the charges produced by the array and a shift register which receives and outputs the charges in the storage parts. A first gate is installed between the array and the storage parts and a second gate is installed between the storage parts and the shift register. The storage time of the charges and the like can be controlled by controlling the first and the second gates by a control circuit. Then, when the subject is of high luminance, the charges are stored into the storage parts with the array and storage parts connected intact to each other by putting the first gating means in the ON state, and the completion of integration thereof is performed by putting the first gate in the OFF state. Also, when the subject is of low luminance, storage of charges is performed in the array with the first gate put in the OFF state, and a dark charges produced in the storage parts during that time is discharged before storing the charges of the above-mentioned arrays.

摘要： A photosensor, or an image sensor made of many such photosensors, including a plurality of photosensor pixels each having a logarithmic converter. The logarithmic converter converts source charges that are produced by a photoreceptor (or a photodiode) and proportional to the amount of the incident light into signal charges logarithmically proportional to the source charges whose amount does not grow so rapid as the amount of source charges grows. Owing to the logarithmic converter, the dynamic range of the photosensor (or image sensor) has a very wide dynamic range.

摘要： The movement detecting circuit of this invention has a band detecting circuit for detecting the signal components of a plurality of image signals. The output signal of this band detecting circuit is input into a band varying circuit for varying the band characteristics of the image signals. The plural image signals having had the band characteristics varied in the band varying circuit are input into a difference signal producing circuit which produces a difference signal of pixel signals approaching respective plural image signals representing the images of an object imaged at different times. A correlation amount between the corresponding plural difference signals produced by the difference signal producing circuit is detected in a correlation detecting circuit. The signal output detected in the correlation detecting circuit is quantified in a quantifying circuit.
