Abstract: A 3D projection method and a 3D projection device are provided. The method includes: obtaining first and second eye images, wherein the first and second eye images respectively includes multiple first and second pixel groups, and each first and second pixel group includes a first, second, third, and fourth pixel; respectively generating a first and third projection image based on the first and third pixel of the first pixel group; respectively generating a second and fourth projection image based on the second and fourth pixel of the second pixel group; and sequentially projecting the first, second, third and fourth projection images. The first and third projection images correspond to the first eye image, the second and fourth projection images correspond to the second eye image, and the first and second eye images are respectively one and another of the left eye image and the right eye image.

Abstract: A 3D projection method and a 3D projection device are provided. The method includes: obtaining a first eye image and a second eye image, and forming a fusion image accordingly, wherein the fusion image includes multiple pixel groups, and each pixel group includes a first pixel, a second pixel, a third pixel and a fourth pixel; respectively generating a first projection image, a second projection image, a third projection image, and a fourth projection image based on the first, second, third, and fourth pixel of the pixel groups; and sequentially projecting the first, second, third and fourth projection images. The first and third projection images correspond to the first eye image, the second and fourth projection images correspond to the second eye image, and the first and second eye images are respectively one and another of the left and right eye image.

Abstract: An apparatus is adapted for charging and discharging a battery device having positive and negative terminals. The apparatus includes a power supplying unit operable so as to provide a direct current voltage output, a current control unit coupled to the power supplying unit so as to receive the direct current voltage output therefrom, and a control device coupled to the current control unit and adapted to be coupled to the battery device. The control device enables the current control unit when a battery voltage of the battery device is below a predetermined voltage value, and disables the current control unit when the battery voltage is at least equal to the predetermined voltage value. The current control unit is adapted to be coupled to the battery device in a charging state, where the positive terminal of the battery device is coupled to the current control unit so as to permit charging of the battery device when the current control unit is enabled by the control device.
