Inventor: YAZAKI HIDEKAZU
IPC: G06T5/00
Filed: 1986-05-09
Abstract: PURPOSE:To modify a photograph without inferiority by comparing with an air brush by the actual labor of a human being in a high speed response by weighting the respective picture elements of optional picture data according to a brush pattern determined by an optional function (for instance, Gauss function). CONSTITUTION:A central processing unit CPU1 forms the brush pattern 22 on a main memory device MS2 by the use of a previously applied weighting function. At this time, the size R of the brush pattern is set to a correction area. Subsequently, based on the instruction from the central processing unit CPU1, an arithmetic unit 3 between the picture elements performs the operation between the picture elements between the data of the respective picture elements of an area corresponding to the brush pattern in cost picture data 21 stored on the main memory device MS2 and the corresponding data of the brush pattern 22. When a desired picture cannot be obtained by the operation, an unnecessary picture element is masked by the use of a mask arithmetic function provided in the arithmetic unit 3 between picture elements, thereby a finer modification can be performed.

Title: Zoom lens
Inventor: TSUJI SADAHIKO
IPC: G02B15/12
Filed: 1986-05-10
Abstract: PURPOSE:To easily change the focal length without extending the overall length of a lens system by setting an auxiliary lens system in the image surface side on the optical axis of the second group in a zoom position of the telephoto end to change the focal length of the whole of the system when the second group is moved to the object side to vary the power from the wide angle side to the telephoto side. CONSTITUTION:The back focus in the zoom position of the telephoto end is the sum of the back focus in the wide angle end and the extent of movement of the second group II (absolute value), and consequently, a space in this zoom position of the telephoto end wider than that in the zoom position of the wide angle end is generated in the image surface side of the second group II. An auxiliary lens system C is set in this lens space between the second group II and the image surface which is generated at this time, thereby changing the focal length in a normal variable power range to that of another. That is, a relatively long back focus is attained in the telephoto end in what is called a two-group zoom lens, which is used as a wide angle zoom lens and consists of the first group I having a negative refracting power and the second group II having a positive refracting power because the position of the second group II in the telephoto end is nearer to the object side in comparison with that in the wide angle end.
