  • Publication number: 20240135539
    Abstract: The image processing device 1X includes an acquisition means 30X and a lesion detection means 34X. The acquisition means 30X acquires an endoscopic image obtained by photographing an examination target by a photographing unit provided in an endoscope. The lesion detection means 34X detects a lesion based on a selection model which is selected from a first model and a second model, the first model being configured to make an inference regarding a lesion of the examination target based on a predetermined number of endoscopic images, the second model being configured to make an inference regarding a lesion of the examination target based on a variable number of endoscopic images. Besides, the lesion detection means 34X changes a parameter to be used for detection of the lesion based on a non-selection model that is the first model or the second model other than the selection model.

  • Publication number: 20240127442
    Abstract: The image processing device 1X includes an acquisition means 30X, a variation detection means 311X, a selection means 312X, and a lesion detection means 34X. The acquisition means 30X acquires an endoscopic image obtained by photographing an examination target by a photographing unit provided in an endoscope. The variation detection means 311X detects a degree of variation between the endoscopic images. The selection means 312X selects either one of a first model or a second model based on the degree of variation, the first model making an inference regarding a lesion of the examination target based on a predetermined number of the endoscopic images, the second model making an inference regarding the lesion based on a variable number of the endoscopic images. The lesion detection means 34X detects the lesion based on a selection model that is either the first model or the second model selected.

  • Patent number: 9975398
    Abstract: A front-seat air conditioner and a rear-seat air conditioner, which are independent from each other, are provided. An engine is automatically stopped under preset stop conditions. When the engine is automatically stopped in a case in which the number of passengers is a specified preset number (five, for example) or larger during heating, the operation of the rear-seat air conditioner is stopped (reduction of power consumption) and the operation of the front-seat air conditioner is continued (prevention of windshield glass from being fogged). Thereby, the windshield glass can be prevented from being fogged during the engine's automatic stop, reducing the power consumption of air conditioning.

  • Patent number: 9610826
    Abstract: A blower fan is driven, and conditioning air flows down through an evaporator and then is supplied into a vehicle compartment. An idling-stop condition in a roof-open state is set to make an idling stop to be relatively easily attained, compared to a roof-closed state, so that a fuel economy can be improved. When an outside-air temperature is a specified temperature or higher or a solar-radiation intensity is a specified degree or greater at an engine's automatic stop, the blower fan is driven, so that the conditioning air is supplied toward a passenger in a manner of an electric fan. The evaporator through which the conditioning air flows down is sufficiently cool at the timing right after the automatic stop of the engine. Accordingly, it is preferable to configure such that the sufficiently-cooled conditioning air is supplied for a properly-long period of time.

  • Patent number: 7071529
    Abstract: A semiconductor device includes semiconductor elements and at least one dummy pattern. Each or at least some of the semiconductor elements has a Damascene gate structure or a replacing gate structure and is located in element-forming regions. In addition, at least a dummy pattern is located in a region different from the element-forming regions. The dummy pattern may have a semiconductor element structure of the same or different kind from the Damascene gate structure or replacing gate structure. The dummy pattern may be a pattern of an insulating film, an interface transistor, or an analog circuit capacitor electrode instead of the dummy gate.

  • Patent number: 6310370
    Abstract: A CCD solid-state image sensing device has power supply lines formed from a poly-silicon layer and a silicide layer formed on the poly-silicon layer. The silicide layer has a reduced optical reflectivity that inhibits reflections of light on a surface of the power supply line. The silicide layer is silicon combined with a refractory metal, such as tungsten, molybdenum, titanium, or the like. Further, a surface protective film is formed on the power supply lines. The surface protective film includes silicon nitride having an increased quantity of hydrogen that is supplied to an interface between a channel layer and a diffusion layer in order to promote bonding.
