Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 A high-definition camera with adaptive ambient light comprises: a bottom plate 1, a support column 2 and a top plate 3, wherein the support column 2 is mounted on the upper wall of the bottom plate 1, the top plate 3 is mounted on the upper wall of the support column 2, a shooting structure is mounted on the lower wall of the top plate 3, a fill light structure is mounted on the upper wall of the top plate 3, and a shading structure is mounted on the rear wall of the bottom plate 1; the shooting structure comprises: a shooting device 4 and two light intensity sensors 5; the shooting device 4 is mounted on the lower wall of the top plate 3, the two light intensity sensors 5 are respectively mounted on the lower wall of the top plate 3, and the two light intensity sensors 5 are respectively located on the front and rear sides of the shooting device 4, the shooting structure can complete the shooting of documents, and the light intensity detection is performed by the two light intensity sensors 5, so that the shooting structure can shoot under the most suitable light.

[0030] Specifically, the fill light structure includes: a fill light electric turntable 6, a lamp holder 7 and a plurality of fill light lamp beads 8; the fill light electric turntable 6 is installed on the upper wall surface of the top plate 3, the lamp holder 7 is installed on the driving end of the fill light electric turntable 6, and a plurality of fill light lamp beads 8 are respectively installed on the lower wall surface of the lamp holder 7. When the light is insufficient, the fill light structure can fill light the captured file, and fill light is performed by gradually increasing the light intensity to achieve the best effect of fill light.

[0031] Specifically, the shading structure includes: a rear shading plate 9 and two telescopic shading plates 10; the rear shading plate 9 is installed on the rear wall of the bottom plate 1, and the two telescopic shading plates 10 are respectively installed on the left and right walls of the rear shading plate 9. When the external light is too strong, the utility model uses the shading structure to shade the light, so as to improve the light shielding effect and optimize the shooting environment.

[0032] Specifically, the lower wall of the base plate 1 is installed with shock-absorbing rubber feet 11, the base plate 1 and the support column 2 are connected by bearings, and the support column 2 can rotate, the upper wall of the base plate 1 is provided with slots, and a light board 12 is installed in the slot of the base plate 1, and a strong light warning light 13 is installed on the front wall of the top plate 3, wherein the shock-absorbing rubber feet 11 can absorb some small vibrations to optimize shooting, and the light board 12 can provide background lighting for translucent documents, and the rotation of the support column 2 can drive the top plate 3 to rotate, so that the shooting structure can find a better shooting angle.

[0033] Specifically, a diffuse light surface 14 is provided on the upper half of the rear shading plate 9, and the fill light beads 8 are directly projected onto the diffuse light surface. The diffuse light surface 10 is made of a rough reflective material. The diffuse light surface 10 scatters the light directly projected by the fill light beads 8. The light emitted by the fill light beads 8 is evenly dispersed in the shooting area after scattering, making the overall lighting of the shooting area more uniform, thereby avoiding overexposure caused by the fill light beads 8 directly projecting onto the object to be photographed, affecting the photographing effect of the object to be photographed, wherein the fill light beads 8 The adjustment of the illumination angle is a common technology in the prior art. For example, as described in a patent for an adjustable angle LED lamp bead (publication number CN216113441U), the angle of the lamp bead disk is adjusted to increase the illumination angle and range of the lamp bead. By adjusting the illumination angle of the lamp bead, most of the light from the fill light lamp bead 8 is directly irradiated on the diffuse light surface 10. In one embodiment, the fill light lamp bead 8 can also be installed obliquely, and by adjusting the inclination angle, most of the light from the fill light lamp bead 8 is directly irradiated on the diffuse light surface 10.

[0034] The lower half of the rear shading plate 9 is provided with a mirror surface 15, which is made of a smooth reflective material and can better evenly reflect the ambient light, thereby improving the overall brightness of the object to be photographed and making the ambient light more uniform, so that the object to be photographed can have better uniformity of illumination during the shooting process, thereby improving the overall shooting quality.

[0035] Working principle: When using the utility model, first connect the external AC power supply to the utility model to provide energy for the electrical appliances in the utility model, and then the operator unfolds the file to be photographed and places it on the upper wall of the bottom plate 1 and the light board 12. At this time, the utility model is started, and the shooting device 4 and the two light intensity sensors 5 start to work. At this time, the two light intensity sensors 5 can detect the light intensity reflected by the file near the shooting device 4. If the light is too strong, the strong light warning light 13 starts to flash to remind the operator to block the light. The operator can pull out the two retractable sunshades 10 for shading. If the light intensity is not enough, the fill light electric turntable 6 rotates ninety degrees, and the lamp holder 7 and the top plate 3 are in a mutually perpendicular state (under normal conditions). The light stand 7 and the top plate 3 are in a co-linear state for easy storage). At this time, a number of fill-in light beads 8 are exposed. At this time, the fill-in light beads 8 are better irradiated directly on the diffuse light surface 10. The fill-in light beads 8 include a left-side lamp bead group 16, a middle lamp bead group 17 and a right-side lamp bead group 18 arranged in parallel. At this time, the fill-in light beads 8 light up in groups in sequence. When the two light intensity sensors 5 detect that the light intensity reaches the standard, the fill-in light beads 8 stop lighting up, so that the fill-in light beads 8 can achieve multi-level adjustment and adaptation, so that the ambient light of the object to be photographed can reach a more suitable shooting state. The shock-absorbing rubber feet 11 can absorb some small vibrations to optimize shooting. At the same time, the light board 12 can provide background lighting for the light-transmitting documents, further improving the uniformity of the ambient light and achieving better shooting effects.
