Image Display Method and Device and Electronic Apparatus

Abstract: An image display method, device and electronic apparatus avoid to some extent a problem of a poor display effect due to adjusting an image purely depending on an RGB image conversion algorithm. The solution comprises obtaining a brightness value of current ambient light; performing image conversion on a frame of image having three primary color components to obtain a first display information, the first display information comprising four primary color gray scale values of each pixel in the image; adjusting the first display information to a second display information according to the brightness value, the second display information comprising four primary color gray scale values of each adjusted pixel; and displaying the image according to the second display information.

Image filter and image conversion method

Abstract: PROBLEM TO BE SOLVED: To reduce aliasing as much as possible in a display apparatus that has a delta arrangement type screen of a flat panel display. SOLUTION: In order to reduce the aliasing as much as possible, an image filter for performing a local neighborhood operation is incorporated. The image filter realizes low pass filtering including space frequency limitation that exceeds a Nyquist limit in the diagonal direction that is suitable for the display on the delta arrangement type screen of the flat panel display. Coefficients are optimized by constituting the local neighborhood operation for calculating display brightness from the brightness of N pieces of data points in an input image.

Particle property analysis display device

Abstract: PROBLEM TO BE SOLVED: To provide a particle property analysis display device capable of shortening a decryption work by analyzing a particle image and displaying the particle property three-dimensionally SOLUTION: This particle property analysis display device is equipped with a liquid flow forming means 2, an imaging means 10, an image analysis means 21, an image processing means 31, a display means 50 and an input means 40 The image analysis means 21 comprises a particle image cutting-out means 23 for cutting out each particle image from an imaged image, a particle size item data measuring means 24, a particle shape item data operation means 25, and a three-dimensional data statistical processing means 27 for totalizing two-dimensional frequencies wherein two kinds of specified items are used as two parameters The image processing means 31 comprises a three-dimensional bar graph data conversion means 32 for displaying the totalized two-dimensional frequency wherein the two kinds of specified items are expressed in two orthogonal coordinate axes in a bar graph having one coordinate axis orthogonal to the two coordinate axes, and a two-dimensional display image conversion means 33 for acquiring image formation data by converting the three-dimensional bar graph data into two-dimensional display image data on a specific camera position COPYRIGHT: (C)2007,JPO&INPIT

Radiation image reader

Abstract: PURPOSE:To make the fading of a reading signal in a practical low-temperature area small, to make image quality excellent and to improve the reading sensitivity of the signal by using a specified stimulable phosphor body for a conversion panel and specifying temperature on the inside of a reader incorporating the conversion panel CONSTITUTION:When a radiation source 101 is turned on, the transmitted radiation image of an object 102 is recorded and stored in the phosphor 104 of the radiation image conversion panel 103 Thereafter, the panel 103 is scanned by a stimulating light source 105 and stimulated luminescence emitted by the phosphor 104 is detected by a photodetector 107 At this time, an image recording part and an image reading part are covered with a housing 121 and a means 123 which cools the panel 103 is provided Then, since the phosphor including iodine is used for the panel 103, the intensity of the stimulated luminescence is high Besides, since the panel is cooled to the temperature of 250 deg-300 degK by the cooling means 123, the fading of the intensity of the stimulated luminescence can be suppressed and the signal is easily corrected
