Title: Video camera
Inventor: HASHIMOTO HIROYUKI
IPC: G03B13/12
Filed: 1991-06-11
Abstract: PURPOSE:To recognize a picture border of a photo cameras accurately even when a zoom magnification is changed. CONSTITUTION:A video camera section and a photo camera section are arranged integrally in a cabinet. A zoom lens is employed for an image pickup lens 2 of the video camera and for an image pickup lens 3 of a photo camera. Variable resistors 44, 48 are arranged to the image pickup lenses 2, 3 to apply detection signals SDv, SDp to a controller 27. The picture border ratio of the image pickup pattern and the photo camera pattern differs from the zoom magnification. A data Ds used for controlling a display size of an image pickup pattern displayed on an EVF is outputted from the controller 27 depending on the picture border ratio. A glass plate on which displays a picture frame of the photo camera is arranged onto the screen of the EVF. The image pickup pattern is displayed variably onto the screen of the EVF based on the picture frame of the photo camera. Even when the zoom magnification is changed, the picture border of the photo camera is accurately recognized and the user surely implements the shutter operation and the zoom operation of the photo camera while observing the display pattern of the EVF.

Title: Image quantizing system
Inventor: IKEDA TSUTOMU
IPC: H04N5/14
Filed: 1981-09-04
Abstract: PURPOSE:To obtain a good binary coded image having no blur, by measuring the signal level of a picture element over the entire image and deciding the slice level of the image. CONSTITUTION:A multivalue image signal 14 delivered from a photoelectric converting device 11 is stored in an image storing device 15 and then fed to an intra-image peak value detecting circuit 16 to detect the intra-image peak value 17 representing the entire image. A reference slice level deciding circuit 18 decides the slice level to the entire image from the peak value 17. The signal 14 from the device 15 is fed to a quantizing circuit 20 to be binary coded. Thus a binary coded image signal is delivered. The circuit 18 gives an upper a limit to the slice level by the peak value 17 to prevent the occurrence of blur to the binary coded image which is caused by an excessively high slice level.
