Description

[0001] Cross-reference to related applications

[0002] This application claims priority to Korean Patent Application No. 10-2021-0107437, filed on August 13, 2021, with the Korean Intellectual Property Office, and Korean Patent Application No. 10-2022-0044524, filed on April 11, 2022, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to multi-image stabilization devices, camera apparatuses, and multi-image stabilization methods. Background Technology

[0004] Camera devices used in mobile devices such as smartphones can be equipped with image stabilization technology.

[0005] Smartphones may have technologies such as balance rings that can compensate for high-angle hand tremors, or sensor shifting technology to compensate for high-frequency hand tremors.

[0006] Existing smartphones can employ lens shifting methods to reposition lens assemblies or sensor shifting methods to reposition image sensors for image stabilization.

[0007] For example, in a lens shifting method, a gyroscope sensor is used to measure the angle and frequency of hand tremors, and a driver circuit (driver IC) uses the measured information to shift the lens in the opposite direction to the direction of the hand tremors.

[0008] Furthermore, in the sensor shifting method, a gyroscope sensor is used to measure the angle and frequency of hand tremors, and a driver circuit (driver IC) performs correction by shifting the image sensor in the opposite direction to the direction of the hand tremors using the measured information.

[0009] However, because existing smartphones use lens-shifting or sensor-shifting methods, they can correct low-frequency hand tremors but may not be able to correct high-frequency hand tremors, or they can correct high-frequency hand tremors but may not be able to correct high-angle hand tremors. In other words, existing smartphones may not be able to correct both high-angle and high-frequency hand tremors.

For clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative dimensions, scale, and descriptions of the elements in the drawings may be exaggerated. Detailed Implementation

[0061] In the following description, although exemplary embodiments of the present disclosure will be described, for example, with reference to the accompanying drawings, it should be noted that the exemplary embodiments are not limited thereto.

[0062] The following detailed description is provided to aid the reader in gaining a full understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent upon understanding this disclosure. For example, the sequences of operations described herein are merely illustrative and are not limited to those set forth herein, but may be changed, as will become apparent upon understanding this disclosure, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0063] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will be apparent upon understanding this disclosure.

[0064] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on," "connected to," or "attached to" another element, it can be directly "on," directly "connected to," or "attached to" the other element, or one or more other elements may exist between them. Conversely, when an element is described as being "directly" "on," directly "connected to," or "attached to" another element, no other elements may exist between them.

[0065] As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more of the relevant listed items; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more of the relevant listed items.

[0066] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, first assembly, first region, first layer, or first part mentioned in the examples may also be referred to as a second component, second assembly, second region, second layer, or second part.

[0067] For ease of description, spatial relative terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another as shown in the figures. These spatial relative terms are intended to include not only the orientation depicted in the figures but also different orientations of the device during use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element will consequently be “below” or “lower” relative to said other element. Therefore, the term “above” includes both upper and lower orientations, depending on the spatial orientation of the device. The device may also be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative terms used herein will be interpreted accordingly.

[0068] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. The articles “a,” “an,” and “the” are intended to include plural forms as well, unless the context clearly indicates otherwise. The terms “comprising,” “including,” and “having” specify the presence of the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0069] Due to manufacturing techniques and / or tolerances, variations in the shape shown in the figure may occur. Therefore, the examples described herein are not limited to the specific shapes shown in the figure, but include shape variations that occur during manufacturing.

[0070] In this document, it should be noted that the term “may” is used with respect to examples, such as what an example may include or implement, meaning that there exists at least one example that includes or implements this feature, but not all examples are limited to this.

[0071] As will be apparent upon understanding this disclosure, the features of the examples described herein can be combined in various ways. Furthermore, although the examples described herein have multiple configurations, other configurations are also possible, as will be apparent upon understanding this disclosure.

[0072] Exemplary embodiments provide a multi-image stabilization device, camera apparatus, and multi-image stabilization method that can use lens shifting (or prism tilting) and sensor shifting techniques to correct both high-frequency hand shakiness and high-angle hand shakiness.

[0073] Figure 1 This is a view illustrating a multi-image stabilization device according to an exemplary embodiment of the present disclosure.

[0076] For example, the driver circuit 500 analyzes the gyroscope sensor information GSI to determine whether it is high-angle hand shakiness or high-frequency hand shakiness. Based on the determination result, in the case of high-angle hand shakiness, the driver circuit 500 can drive the lens actuator ACT2 720 to perform lens shift correction, and in the case of high-frequency hand shakiness, the driver circuit 500 can drive the sensor actuator ACT3 730 to perform sensor shift correction.

[0080] In the camera apparatus disclosed herein, lens-shift image stabilization technology can perform high-angle image stabilization by increasing the distance used to move the lens, and sensor-shift image stabilization technology can perform high-frequency image stabilization because the image sensor is lighter than the lens, even though it may be difficult to correct high angles due to the connection of the stretchable printed circuit board (PCB), which will be described in detail below.

For example, lens assembly 120 may be moved into position in a direction perpendicular to the optical axis (e.g., the Z-axis) (e.g., the X-axis or Y-axis) by lens actuator ACT2 720. Based on the positional movement of lens assembly 120, shift correction can be performed on high-angle hand shake of camera body 100.

[0102] The image sensor unit 130 may include an image sensor 131 that converts incident image light into an image signal and a substrate 132 on which the image sensor 131 is disposed. The substrate 132 may be a PCB substrate, but is not limited thereto.

[0103] For example, the image sensor unit 130 can be moved into position in a direction perpendicular to the optical axis (e.g., the Z-axis) (e.g., the X-axis or Y-axis) by the sensor actuator ACT3 730.

[0106] To change the incident optical axis, the prism unit 110 can be positioned at the entrance side of the light incident from the camera body 100, and can change light incident along the X-axis direction to light along the Z-axis direction. For example, the prism unit 110 can be moved vertically and horizontally by the prism actuator ACT1 710.
