  • Publication number: 20210381885
    Abstract: The disclosure provides a light-emitting element inspection device optically connected to at least one light-emitting element of a test object and including a dark box, a slide rail, an image-capturing device, a light-entrance plate, and a processor. The slide rail and the image-capturing device are disposed in the dark box. The image-capturing device slides on the slide rail. The light-entrance plate is disposed on one side of the dark box and has at least one hole optically connected to the light-emitting element. The image-capturing device is aligned with the light-entrance plate to capture an image of the light-entrance plate. The processor is coupled to the image-capturing device and is adapted to obtain a set of RGB values of the image, convert the RGB values into a set of HSV values, and determine whether the light-emitting element of the test object conforms to a standard based on the HSV values.

  • Publication number: 20170119196
    Abstract: A thermo tea maker includes a tea cup and a tea infuser. The exterior of the tea cup has a first isolation gap in a vacuum state to block the heat conduction from an inner part to an outer part of the cup part. The exterior of the tea infuser has a second isolation gap in a vacuum state to block the heat conduction from an inner segment to an outer segment of the tea infuser. The tea cup and the tea infuser are able to keep the tea warm. When the tea infuser is turned, the tea infuser will not scald the user's hand.

  • Publication number: 20160360918
    Abstract: A rotary tea maker includes a tea cup and a tea infuser. After the tea is brewed in a tea brewing room of the tea infuser, through rotation of the tea infuser, the tea is discharged from the tea brewing room to be stored in a tea room of the tea cup for use. The tea in the tea brewing room flows to a passage from a water outlet of the tea infuser and then enters the tea room from a through hole of the tea cup. During the process, the air in the tea room is expelled to the passage from the through hole when the tea is poured and then flows to the tea brewing room through an air hole of an air pipe of the tea infuser, so that the tea in the tea brewing room can be discharged to the tea room smoothly.

  • Patent number: 8830402
    Abstract: An image processing circuit and a method thereof are provided herein. The image processing circuit has a first scaling circuit, one or more line buffers, a first sharpness circuit, a second scaling circuit, and a second sharpness circuit. The first scaling circuit enlarges an input image along a first direction to generate a first enlarged image. The one or more line buffers temporarily store the pixel values of a plurality of pixel rows of the first enlarged image. The first sharpness circuit vertically sharpens the first enlarged image to generate a first sharpened image. The second scaling circuit enlarges the first sharpened image along a second direction to generate a second enlarged image. The second sharpness circuit horizontally sharpens the second enlarged image to generate a second sharpened image. Accordingly, it is possible to use the one or more line buffers having shorter data lengths to perform the vertical sharpening.
