Alternatively, after the first photographing band light sensing region 112 absorbs the first photographing band light in the first light, the remaining light continues to be transmitted to the depth of field measurement pixel unit 104. For example: the first photographing band light sensing area 112 may absorb red light, the first light transmission area 117 may transmit the red light and the depth of field measurement light, and the red light and the depth of field measurement light are obtained by filtering through the first light transmission area 117, the first photographing band light sensing area 112 absorbs the red light, and the depth of field measurement light continues to be transmitted to the depth of field measurement pixel unit 104.

Alternatively, after the second photographing band light sensing region 113 absorbs the second photographing band light in the second light, the remaining light continues to be transmitted to the depth of field measurement pixel unit 104. For example: the second photographing band light sensing area 113 may absorb green light, the second light transmission area 118 may transmit the green light and the depth of field measurement light, the green light and the depth of field measurement light are obtained by filtering through the second light transmission area 118, the second photographing band light sensing area 113 absorbs the green light, and the depth of field measurement light is continuously transmitted to the depth of field measurement pixel unit 104.

Alternatively, the third light required by the third photographing band light sensing region 114 and the depth measurement pixel unit 104 may include the light required by the third photographing band light sensing region 114 and the depth measurement pixel unit 104. Alternatively, the third light required by the third photographing band light sensing region 114 and the depth-of-field measurement pixel unit 104 may also include light unnecessary for the third photographing band light sensing region 114 and the depth-of-field measurement pixel unit 104, which does not interfere with the third photographing band light sensing region 114 and the depth-of-field measurement pixel unit 104. Alternatively, after the third shooting band light sensing region 114 absorbs the third shooting band light in the third light, the remaining light continues to be transmitted to the depth-of-field measurement pixel unit 104. For example: the third photographing band light sensing area 114 can absorb blue light, the third light transmission area 119 can transmit the blue light and the depth of field measuring light, the blue light and the depth of field measuring light are obtained by filtering through the third light transmission area 119, the third photographing band light sensing area 114 absorbs the blue light, and the depth of field measuring light is continuously transmitted to the depth of field measuring pixel unit 104.

In addition, the shown or discussed mutual coupling or direct coupling or communication connection may be an indirect coupling or communication connection through some interfaces, devices or units, and may be in an electrical, mechanical or other form. Units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the units can be selected according to actual needs to implement the present embodiment. In addition, functional units in the embodiments of the present disclosure may be integrated into one processing unit, or each unit may exist alone physically, or two or more units are integrated into one unit.

In the drawings, the width, length, thickness, etc. of structures such as elements or layers may be exaggerated for clarity and descriptive purposes. When an element or layer is referred to as being "disposed on" (or "mounted on," "laid on," "attached to," "coated on," or the like) another element or layer, the element or layer may be directly "disposed on" or "over" the other element or layer, or intervening elements or layers may be present, or even partially embedded in the other element or layer.
