An-mediated genetic transformation method for sea barleygrass is provided. The method includes: S1, selecting immature embryo materials of sea barleygrass with immature embryos each having a length in a range of 0.5-1.0, sterilizing them with alcohol and sodium hypochlorite to obtain sterilized seeds; S2, separating the immature embryos, crosscutting the immature embryos, and inducing callus generation and proliferation; S3, adjusting pre-culture time andinfection time of calli based on the callus generation andgrowth to thereby prevent excessiveliquid; and S4, performing adventitious bud induction culture and rooting induction culture under a shielding-formed low-light environment to obtain tissue culture plantlets. It relates to a tissue culture method for immature embryos of sea barleygrass with high green spot differentiation and plantlet formation rates, which is not limited by materials. A transformation and regeneration system has high genetic transformation and mutation efficiency.

An image capture device, a control method and a machine readable storage medium are disclosed. The image capture device includes: a processor, an infrared lamp, and a white light lamp. The processor in the image capture device is used to control the infrared lamp and white light lamp. The processor obtains current acquisition parameters of the image capture device, compares the magnification in the current acquisition parameters with a preset first magnification threshold and a preset second magnification threshold to obtain a comparison result, and controls switching states of the infrared lamp and the white light lamp according to the comparison result, the brightness of the environment and the gain, wherein, the first magnification threshold is less than the second magnification threshold.

Image capture device includes white light lamp and infrared lamp for capturing better quality images when the brightness of the environment is moderate
