  • Publication number: 20190194593
    Abstract: According to an aspect of the invention, an observation system includes at least one observation apparatus and a thermostatic bath. The observation apparatus includes an imaging unit, a temperature sensor, and first control circuitry. The imaging unit captures an image of the sample. The temperature sensor measures an internal temperature of the observation apparatus. The first control circuitry estimates a sample temperature based on the internal temperature and calculates an indication temperature based on the sample temperature and temperature distribution data of the thermostatic chamber. The thermostatic bath includes a memory and second control circuitry. The memory stores the temperature distribution data. The second control circuitry performs the temperature control by setting a set temperature based on the indication temperature.

  • Patent number: 7554535
    Abstract: In a display, the reduction in brightness which is a problem of the mobile picture improving method in a black reset scheme is reduced to a minimum value and a clear image is displayed. The display includes a movement amount extracting unit 42 to extract an amount of movement from a time series image signal and a ratio setting unit 43 to set a first period (image gradation display period) to conduct image display on the display element and a second period (black reset period) to display black image thereon according to the extracted amount of movement.

  • Patent number: 7483574
    Abstract: To provide an image processing apparatus and an image transmission apparatus capable of image display as excellent as a normal raster image even when the memory capacity is reduced in a display having a built-in memory, and an image processing method. The image processing apparatus of the present invention performs multi-valued dither processing at an image processing former stage 4 when a raster image 1 is input to a memory 2, and the raster image output from the memory 2 is subjected to reverse processing to the multi-valued dither processing in an image processing latter stage 5. With this construction, it is possible to obtain a display apparatus capable of suppressing a grainy feeling and pseudo colors, thereby realizing high quality images.

  • Patent number: 6911784
    Abstract: A display apparatus according to the present invention includes: a pixel including a plurality of sub-pixels; and a control unit which makes a control such that each of the plurality of sub-pixels is subjected to represent gradation with a plurality of levels. When a first sub-pixel of the plurality of sub-pixels represents one of a minimum gradation level and a maximum gradation level of the gradation with the plurality of levels, the control unit makes a control such that a second sub-pixel adjacent to the first sub-pixel of the plurality of sub-pixels represents other than the other of the minimum gradation level and the maximum gradation level. Thus, the display apparatus according to the present invention can suppress deterioration of picture quality caused by a configuration effect.

  • Publication number: 20010048771
    Abstract: An image processing method is provided, which makes it possible to enlarge an input or original image in such a way as to suppress or eliminate jaggies at the contours in the image, and which is applicable to a dot-matrix type display device with a fixed resolution. In the step (a) a local area is defined in an input image. The local area includes a target pixel and neighboring pixels surrounding the target pixel. In the step (b), a filtering operation is applied to the target pixel and the neighboring pixels in the local area while all the pixels in the local area are successively assigned to the target pixel, thereby outputting a filtered image. In the step (c), the filtered image and the input image are mixed together at a specific mixing ratio, thereby forming an output image. In the step (b), the median or average value is preferably used for forming the filtered image.
