  • Publication number: 20240263112
    Abstract: A culture device includes an accommodation portion that accommodates a culture solution and microalgae. The accommodation portion is provided with a guide portion and a gas supply portion. The gas supply portion includes an extended tube section that extends from an upper portion to a lower portion of the guide portion in the depth direction. The extended tube portion supplies gas at the lower portion of the guide portion in the depth direction. This gas causes convection in the culture solution. The convection includes an upward flow from a lower portion to an upper portion of the accommodation portion in the depth direction. The extended tube portion is located in an upward flow region where the upward flow region is the portion through which the upward flow passes.

  • Publication number: 20230091342
    Abstract: An anti-dazzle system includes a first obtainer, a second obtainer, a light reducer, and a control unit. The first obtainer obtains image data of a captured image of a surrounding environment from a first imaging sensor. The second obtainer obtains information for detection from which a movement of a head of a user is detectable, from the detection sensor. The light reducer includes a light reducing region that reduces an amount of light transmitted and is capable of moving the light reducing region in a predetermined range. The control unit detects a position of a light source included in the captured image of the surrounding environment based on the image data, and causes the light reducer to place the light reducing region between the light source and the head based on the position of the light source and the information for detection.

  • Patent number: 9282240
    Abstract: An imaging device includes a controller; an image sensor connected to the controller and outputting RAW data; and a memory connected to the controller. The image sensor is configured to output the RAW data to the controller at a predetermined pixel output rate. The controller generates first image data by reducing the RAW data output from the image sensor. The controller generates second image data by carrying out correction processing with respect to the first image data. The controller is configured to store the RAW data output from the image sensor and the second image data in the memory.
