  • Patent number: 10835109
    Abstract: An endoscope system includes: an imaging device detachably connected to an eyepiece unit of an endoscope inserted into a subject, the endoscope taking a subject image inside the subject from a distal end thereof, and the imaging device being configured to capture the subject image taken by the endoscope; a detection area setting unit configured to set a detection area in the captured image captured by the imaging device; a detection processing unit configured to execute, based on an image in the detection area in the captured image, a detection process for calculating an evaluation value of the image; and a subject image determining unit configured to determine a size of the subject image in the captured image, wherein the detection area setting unit changes an area of the entire detection area based on a determination result of the subject image determining unit.

  • Patent number: 5999161
    Abstract: An apparatus and method for extracting a desired portion of an image represented by compressed data. The compressed data is expanded in an expanding circuit and outputted therefrom in accordance with clock pulses. Such clock pulses, or data transfers or addresses associated therewith, are counted so as to determine the position of the data. The determined position of the data is compared to the desired portion so as to determine whether the data is within the desired portion. If the data is determined to be within the desired portion, such data is stored in an image memory. As a result, such extraction may be performed without utilizing an additional memory for temporarily storing the expanded data.

  • Patent number: 5999697
    Abstract: A still image recording/reproducing apparatus for recording and/or reproducing still image data and audio data onto and/or from a recording medium, such as a magneto-optical disk. Characters and/or patterns may be provided with the still image. Additionally, the still image may be modified and/or the size thereof may be increased or decreased.

  • Patent number: 5838394
    Abstract: A picture storage device conveniently employed in conjunction with an electronic still camera or a video camera has an input data converting unit for separating luminance signals of input color picture data having a non-interlaced data format with the sampling rate of the luminance signals and two-route color signals of 4:2:0 into a data string of even-numbered pixels and a data string of odd-numbered pixels, separating the two-route color signals of the color picture data into a data string of the former half pixels and a data string of the latter half pixels, and distributing and re-arraying the separated data, a storage unit having a storage capacity of at least one frame and adapted for storing data in a data re-arraying sequence by the input converting unit, a display data converting unit for converting the data stored in the storage unit into picture-displaying data, and a controller for controlling the input converting unit into synchronization with data writing in the storage unit.

  • Patent number: 5689310
    Abstract: A fader device for processing picture data supplied from outside, such as from a video tape recorder or a camera, with fade-in or fade-out processing with a desired color. For fade-in, a subtractor subtracts the color picture data supplied from a designated color picture data forming unit from picture data supplied from outside and transmits the resulting difference data to a multiplier, which then multiplies picture data from the subtractor with a gradually increasing coefficient supplied from the gain control unit and routes the result of multiplication to an adder. The adder adds picture data supplied from the multiplier to the color picture data supplied from the designated color picture data forming unit and routes the resulting addition signal to a monitor unit. For fade-out, the subtractor subtracts the color picture data supplied from the designated color picture data forming unit from data supplied from outside and routes the resulting difference signal to the multiplier.

  • Patent number: 5274457
    Abstract: A digital electronic still camera wherein additional information such as an operation characteristic of the camera can be recorded into and reproduced from a removable record medium. A pickup image signal is picked up by a CCD image sensor and converted into a digital signal by an analog to digital converter. The digital signal is temporarily stored into a digital memory and written onto a removable optical disk apparatus. The digital electronic still camera further comprises an additional information recording and reproducing circuit for recording and reproducing additional information such as an operation characteristic of the camera onto or from the optical disk apparatus.

  • Patent number: 4864431
    Abstract: In a magnetic tape recording system having a single master tape player and a plurality of slave recording devices each including at least one rotary magnetic head for repeatedly scanning a respective magnetic recording tape, and each receiving, from the single master tape player, a signal to be recorded along with an external sync or reference signal; each of the slave recording devices is provided with a respective time base adjusting memory in which the signal to be recorded is written in synchronism .with the external reference signal, and from which the signal to be recorded is read-out in synchronism with a reference pulse generated in timed relation to a predetermined rotational position of the respective rotary magnetic head.
